In the military, innovation has driven military conquest as someone found new ways to do something that was better than what came before. However, in SpeculativeFiction, it seems that a lot of people have decided [[NinjaPirateZombieRobot combining previous concepts into one über-machine]] is easier than [[CreativeSterility coming up with something original]].

Enter the Military Mashup Machine. In reality, some of these would be [[AwesomeButImpractical far more expensive than practical]], with other existing military technologies being much easier to get the same results from, but [[RuleOfCool if it looks cool]], why not present it as worthwhile?

While generally members of SpeculativeFiction or ScienceFiction, these can also show up in SteamPunk as well. See AirborneAircraftCarrier and TheBattlestar for specific {{Sub Trope}}s.

[[folder: Land Battleship]]
The [[BaseOnWheels Land Battleship]] is a landgoing vehicle bristling with heavy artillery, generally the equivalent of a naval vessel's guns only on land, or rather, a ''really'' big tank. Often used in deserts and grasslands.

[[folder: Anime & Manga ]]

* ''Franchise/{{Gundam}}'' has a slight love affair with these, which have featured from the beginning to the more recent ''[[Anime/MobileSuitGundamSEEDDestiny Gundam SEED Destiny]]''. Perhaps the most bizarre version was the Battleships of the [[Anime/MobileSuitVictoryGundam Zanscare Empire's]] land forces, such as the [[http://www.mahq.net/mecha/gundam/v/adrastea.jpg Adrastea-class]], which were essentially naval ships on enormous motorcycle wheels.
** The ''[[Anime/MobileSuitGundamSEED Gundam SEED]]'' spinoff ''[[Manga/MobileSuitGundamSEEDAstray Gundam SEED Astray]]'' shows that that universe's land battleships are ''amphibious''; though designed specifically for land combat, they use an exotic "scale system" that works just as well on water as on land. ''[[Anime/MobileSuitGundamSEEDDestiny Gundam SEED Destiny]]'' reverts to the relatively more conventional "giant tank" with tracked propulsion in the form of the [[http://www.mahq.net/mecha/gundam/seed-destiny/hannibal.htm Hannibal class]].
* ''TengenToppaGurrenLagann'' goes typically overboard, by making the [[http://www.gurren-lagann.net/mecha/images/daigurren.gif featured land battleship]] a literal ''battleship on legs'' and a HumongousMecha to boot (ironically, it requires special adjustments to cross water). General Guame's Dai-Gundo is more typical of this kind of thing. [[spoiler: Ignore the phallic connotations of its design.]]
** Those special modifications include (and apparently consist entirely of) a HumongousMecha-scaled ''kayak paddle'' and ''flippers''. It's even seen paddling its feet like a duck.
** The humanoid designs are [[JustifiedTrope justified]], as in the series, the human form is more conducive to spiral energy.
* The ''Rhinoceros''-class ships in ''VideoGame/SuperRobotWarsOriginalGeneration''.
* ''CodeGeass'' gives us [[http://codegeass.wikia.com/wiki/Vehicles#G-1_Base several]] [[http://codegeass.wikia.com/wiki/Vehicles#Longdan types]] of land bases, which are basically airships on the ground (until they perfect the float systems, anyway). The actual development of Knightmares themselves were stated to be a result of this, since the 1st and 2nd "Generations" were the result of cobbling together existing technology (Factspheres, Landspinners, emergency cockpits, legs, etc.) together ForScience. The 3d generation Ganymede was the first true unique advancement in the technology.
* ''MaiOtome'' has these as well (and normally used as the launch platforms for the ''Otome's'' themselves), considering the planet where the story takes place is a ''Desert Planet''. Heck even a civilian ferry travels on land.

[[/folder]]

[[folder: Literature ]]

* The titular Land Leviathan from MichaelMoorcock's 1974 novel "The Land Leviathan".
* The ''original'' land battleship, from the story "The Land Ironclads," by H.G. Wells, is possibly the earliest example, predating actual tanks.
* Creator/KeithLaumer's ''Literature/{{Bolo}}s'': automated (and eventually artificially intelligent) land battleships of the Dinochrome Brigade (called "continental siege units" in early stories) which grew to have more firepower than the space battleships that transported them. (Their main guns are generally fusion lances with output measured in ''megatons per second''.) The largest models are capable of defending or conquering an entire planet, solo, and they, rather than their commanders, are the ''de facto'' protagonists of the stories where they appear.
* ''Literature/LegacyOfTheAldenata'':
** The Tiger [=IIIs=] from ''Watch on the Rhine'' are land battleships. The design of the Tiger III is never specified, but it is also known to be capable of shooting down spacecraft in low orbit as well as taking out swarms of [[HordeOfAlienLocusts Posleen]].
** The [=SheVa=] unit "Bun-Bun" has added weapons and equipment to arguably make count as a land battleship, but it still isn't quite on the same level as the Tiger [=IIIs=]. Other [=SheVa=] units, however, are more akin to just really big mobile artillery pieces.
* Creator/RobertAHeinlein's short novel ''IfThisGoesOn...'' has the major land force of the USA be Land Battleships.
* Scott Westerfeld's Literature/{{Leviathan}} features Land Frigates, which are essentially actually German Battleships with [[SpiderTank legs]].
* Spoofed in the HarryHarrison short story ''Navy Day''. The US Army declares their waterbourne rivals obsolete after developing a technology that enables vehicles to drive on the ocean. Naval scientists work frantically while Congress debates whether to abolish the Navy once and for all -- just as they are about to vote in favor the Admiral points to the battleship now 'sailing' down Constitution Avenue.
* Subverted in Harry Turtledove's ''Literature/WorldWar'' series. [[ScaryDogmaticAliens The Race]] has "landcruisers" but they're just normal-sized tanks, the lizards hadn't really bothered to come up with many specialized words for their military technology since they'd fought only ''two'' wars in the past 100,000 years before invading earth.
** At the same time, they have the word "cruiser", which is a naval term, despite the Race hailing from a [[SingleBiomePlanet desert world]] with no oceans or any other major bodies of water. In fact, it's specifically mentioned that our battleships and aircraft carriers are a mystery to them. They also call their spacecraft "ships", and it's not just TranslationConvention either. A Chinese woman who has studied their language wonders why "planes that never land" are called "ships". The Race obviously can't think of space travel in terms of SpaceIsAnOcean because they never had an AgeOfSail.

[[folder: Live Action TV ]]

* [=GoGoVoyager=] from ''Series/GoGoSentaiBoukenger'' is basically a battleship with wheels (and a terrain-flattening roller), able to go from sea to land and leave a path of devastation. Did we mention [[CombiningMecha it also seperates into five assault vehicles]] [[HumongousMecha AND combines again into a big horkin' robot?]]
* [[Series/KyoryuSentaiZyuranger Ultimate Daizyujin]]/[[Series/MightyMorphinPowerRangers Ultrazord]]. DescriptionPorn warning: Start with an oversized robot brachiosaurus on wheels. Split the tail into two {{BFG}}s, and put one on each front shoulder. Take a skyscraper-sized robot formed from a robot TyrannosaurusRex, a robot mammoth/mastodon, a robot triceratops, a robot smilodon, and a robot pterosaur, and a robot aquatic dragon. Remove the chest armor and tail from the dragon, and retract its missile-launcher hands into the shoulders. Then tilt the feet around, split it at the middle, and put it on the humanoid robot as armor, making sure to tilt the head crest up. Put the brachiosaur's chestplate (which has several firing barrels) on the humanoid robot's chest, and put its front paws on the humanoid robot as gauntlets. Attach the dragon's tail to the and chestplate to the brachiosaurus in the appropriate spots. Then stand the humanoid robot in a bay in the brachiosaurus' back. Voila. The resulting machine can roll along at a good clip, and packs enough firepower to blow up even the devil.

[[folder: Tabletop Games ]]

* The Imperial Baneblade in ''TabletopGame/{{Warhammer 40000}}'' is a tank the size of a large house and mounts no fewer than 11 separate weapons, ranging from heavy bolters (firing fully-automatic armor-piercing mass-reactive explosive gyrojet rounds) to laser cannons to ginormous conventional cannons. It's also the standard chassis for a whole family of super-heavy tanks, including variants like the Shadowsword [[HumongousMecha Titan]]-killer, which sports a [[{{BFG}} Volcano Cannon]] that's usually carried by the Titans it's designed to destroy. Larger Imperial land battleships include the Ordinatus (a tracked WaveMotionGun), Leviathan (mobile command centre, basically a BaseOnWheels), and the Capitol Imperialis (a tracked castle packing a potent cannon while still having room for two companies of ''tanks'').
** Chaos forces have daemonically possessed/traitorous versions of all the above, sporting screaming mouths the size of houses and bladed tentacles the size of trains.
** The [[OurDwarvesAreAllTheSame Squats]] favored these sort of engines over HumongousMecha, including the Cyclops, a rolling juggernaut that's approximately fifty percent [[NamesToRunAwayFromReallyFast Hellfury Cannon]], and of course the [[CoolTrain Land Train]]. The aforementioned Leviathan was originally a Squat invention as well.
* The ''Ogre'', one of several classes of autonomous robotic moving fortresses from the game of the same name (and its successor, ''G.E.V.'') from Steve Jackson Games. The concept is partially derived from Creator/KeithLaumer's ''Literature/{{Bolo}}s'', and partially from Steve Jackson's need to reduce the numbers of counters he had to put in each box. In the original game, a combined arms force consisting of powered armor infantry, tanks, artillery, and hovercraft, each of whom, in the game universe, fires ''nuclear weapons'', opposes ''one'' unit -- the Ogre. In the original scenario, where all the defenders have to do is prevent the Ogre from reaching a specific point on the gameboard, the Ogre usually wins.
* ''DystopianWars'' has Land Battleships large enough to mount [[UpToEleven Saint Paul's Cathedral]] on their backs, while also carrying various weapons that make them more than able to live up to their moniker.

[[/folder]]

[[folder: Video Games ]]

* ''VideoGame/PlanetSide'' - The Sunderer (and its variants) are basically ''giant'' buses as large as a house, with massive spikes on front, tank cannons on top, and ball turrets on the sides. And they can carry [[PoweredArmor MAX units]]. Oh, and they can use a EMP pulse on anything near them, making them minefield sweepers as well. ''Planetside 2'' drops most of their armaments in exchange for the ability to [[BaseOnWheels anchor down and activate a spawning field]], or phase through base shields.
* ''VideoGame/{{Haze}}'' - The Land Carrier is what its name suggests: rather than a Land Battleship, it's a rather useless land helicopter carrier which seemingly whiles away the hours by driving in circles.
* ''VideoGame/MetalSlug''
** ''Metal Slug 2'' - The [[http://metalslug.wikia.com/wiki/Big_Shiee Big Shiee]], the boss of mission four.
** ''Metal Slug 5'' also has the boss of Mission four, which is a Land ''Submarine'' that can [[SandIsWater submerge itself in the desert]].
* ''VideoGame/SupremeCommander'' - The Fatboy actually mounts battleship calibre guns on rotating turrets. And it has a landing pad on top. Taking it even farther are the Salem Class destroyers of the Cybran Nation which are actual warships which sprout spider legs when they reach land in order to render them amphibious They are ships on legs!
** In the sequel, all of the Cybran ships can do that, with the right research.
* A recurring unit from the ''VideoGame/CommandAndConquer'' games is the Mammoth Tank, a two-barreled behemoth with anti-aircraft rockets that's big enough to crush other tanks. It's a staple of the Global Defense Initative in the ''[[CommandAndConquerTiberiumSeries Tiberium]]'' series (though it's technically a ''[[HumongousMecha walking]]'' battleship in ''Tiberian Sun''), while the Soviets in the ''[[CommandAndConquerRedAlert Red Alert]]'' series eventually rename it the Apocalypse tank. Even in ''CommandAndConquerGenerals'', the Chinese get a similar Overlord tank, which is big enough to support a bunker, gatling turret, or propaganda tower.
** In the ''Kane's Wrath'' expansion for ''CommandAndConquerTiberiumWars'', GDI also gains the MARV, which is an even ''bigger'' mobile treaded deathmobile with ''three'' railguns, garrisonable infantry bunkers, and the ability to consume entire Tiberium fields instantly.
** On another note, there's also the Juggernaut artillery walker, which is more or less a Battleship turret on legs.
** ''VideoGame/CommandAndConquerRedAlert3'' does one better, with ''amphibious battleships.'' Not a battleship-sized tank on treads, but a literal [[http://portal.commandandconquer.com/portal/site/redalert/template.MAXIMIZE/factions_en/?javax.portlet.tpst=887f789b1e9f05362087dce7b100cda0_ws_MX&javax.portlet.prp_887f789b1e9f05362087dce7b100cda0_viewID=proxy_view_secondary&javax.portlet.prp_887f789b1e9f05362087dce7b100cda0_wcproxyurl=http%253A%252F%252Flocalhost%253A8080%252FSiteAssets%252Ffactions%252FAssault_Destroyer.html battleship on treads.]]
* See VideoGame/SupremeCommander's Salem-Class, above.
* The Marmotah and Batomys from ''VideoGame/ValkyriaChronicles'' fits this trope to a T.
* ''[[NoituLove Noitu Love 2]]'' has one as its [[http://www.youtube.com/watch?v=XK37gN7kCwQ very first boss]]. Humorously, when defeated, it sinks despite being fought ''on a city street''.
* ''VideoGame/ArmoredCore: For Answer'' hinges on destroying incredibly HumongousMecha that are land (and sometimes air or water) battleships. The gigantic carrier-type beasts are oversized and difficult to control. They are, however, valuable in that they project an obscene amount of power into an area, and can move to another area relatively easily. They are also extraordinarily frightening to fight: when the ten-meter tall mech that you're piloting isn't as big as the ''smallest gun'' on the carrier, you ''know'' you're in trouble.\\
\\
The corporations which deploy them appreciate that [[CrewOfOne no one person can control them]]. As oppossed to the HumongousMecha such as the one piloted by the protagonist.
* ''VideoGame/TalesoftheAbyss'' gives us a literal land dreadnought, the Tartarus.
** Even better it can ''float'' in water, and goes on to be the party's first global transport. It's not amphibious though; as resident SmartGuy Jade points out it's "just a landship that happens to float on water". It was never really meant to be used as a boat. In fact, by the time you get it, the Tartarus' propulsion systems are so mucked up that it can never travel on land again.
* In ''ChromeHounds'', there's the Tarakian Unidentified Weapon, "M-99 Super Patriot". It is literally a Modern-day Supertanker (you know, the giant, 5 mile long ocean going ship), loaded down with [[{{BFG}} giant (triple barreled) cannons]], [[KillItWithFire flamethrowers]], and [[GunsAkimbo lots]] [[MoreDakka and lots]] [[GatlingGood of gatling guns]]. It also is a mobile HQ for enemy forces- and launches a bottomless supply of enemy [[GoddamnBats ACVs]].
* ''[[{{Area88}} U.N. Squadron]]'' - Land carriers are used for a few bosses.
* The ''Call to Power'' series has Leviathans, enormous, heavily armed with most weapons of that particular period in that game, but extremely slow moving. In game, the unit is more powerful in every combat statistic than every other unit, but can only move one square per turn, even on roads. Fusion tanks in the same series might also apply.
* The arcade game series ''Raiden'' is chock-full of these, to the extent that in the later games, even the {{Mooks}} are a good example of the "smaller" types.
** The Stage 4 boss in the original is a mobile TempleOfDoom.
* Cocoon in ''VideoGame/MetalGearSolidPeaceWalker'' is basically a battleship mounted on treads, complete with a hedgehog.
* The screen-filling supertank bosses (called "Think Tanks" in the manual) in ''Iron Tank''.
* The final stage of ''VideoGame/BattleGaregga'' has a giant land-based aircraft carrier.
* ''VideoGame/StarcraftII'' has the Odin, a prototype HumongousMecha that is practically indestructible and can tear apart entire bases single-handedly. Its impracticality is [[LampshadeHanging lampshaded]] by Raynor's engineers, who design the scaled-down Thor based on it.
* ''EndOfNations'' features a massive battleship sized tank called the Panzer Hulk armed with more than a [[MoreDakka dozen cannons]].
* ''VideoGame/{{Fallout 3}}: Broken Steel'' has the Enclave's Mobile Base Crawler, which is based on a space shuttle transport crawler.
* ''VideoGame/{{Fracture}}'' features the Dreadnought, a walking amphibious land battleship that the Pacificans are hoping will win them the war with one quick knock-out blow.
* ''VideoGame/MarchOfWar'' features the European Alliance's Siege Tank and the Shogun Empire's Akuma class Landship, dieselpunk land-battleships in the 1940s.

* ''GIJoe'' has had a number of these in toy form, although they rarely appeared in the cartoons. One of them, the General ([[http://en.wikipedia.org/wiki/General_(G.I._Joe) The Other Wiki link]]) did recieve the focus of an entire episode. Driven by the Russian guy no less. Go peristrokia.
* The Land Titanic from ''{{Futurama}}''. Though it sank.
* The Nazi wheel tank from the ''WesternAnimation/JusticeLeague'' episode "The Savage Time". These were taken from the old ''ComicBook/{{Blackhawk}}'' comics during that time.
* [[LosingYourHead Skullus]], one of the [[EvilSorcerer Evil Sorcerers]] from ''WesternAnimation/ThundarrTheBarbarian'', possesses [[http://images.wikia.com/thundarr/images/b/bb/Skulluslandmachine.png a huge war machine]] which runs the gamut from land battleship to BaseOnWheels...er, treads.

[[folder: Real Life ]]

* TruthInTelevision: there was such a school of thought in 1920s to 1930s advocating the use of powerful vehicles to serve as trench-breakers and infantry support. As the expected pace of warfare was restricted by both technological limitations and the speed of infantry, these largely concentrated on larger and more heavily armoured vehicles.
** Both the British and Germans considered building these during UsefulNotes/WorldWarII. The Germans prototyped at least one, with several more designs in the works before the war's end prevented their construction. By contrast, the British eventually gave up on the concept due to it being more expensive than it would be worth.
** [[http://www.achtungpanzer.com/panzerkampfwagen-viii-maus-porsche-typ-205-tiger-iip.htm Panzerkampfwagen VIII Maus]]. "Mouse". At 188 tons, it is the heaviest tank ever constructed. Yeah, they really built this monstrosity. Two prototypes were built; the V1 had a weighted mockup turret with no weaponry, while the V2 had a real turret and armament. Both were captured by Russian troops, but the V2 was gutted by internal explosions in the process. The turret from the V2 prototype survived reasonably intact, and was lifted off the ravaged V2 hull (using six captured 18-ton halftracks) and mated with the V1 hull. This hybrid vehicle was returned to Russia, and survives to this day [[http://en.wikipedia.org/wiki/File:Metro-maus1.jpg on display]] at the Kubinka tank museum.
*** [[RealityEnsues Reality Ensued]]: it was a total failure. Sure, it had a {{BFG}} and was a fortress on wheels, but it broke windows on nearby buildings when it moved, and bogged down on anything except asphalt, cobblestone, or concrete.
** One proposed German design featured ''a pair of battlecruiser cannon''. It's none other than the [[http://www.militaryfactory.com/armor/detail.asp?armor_id=293 Landkreuzer P. 1000 Ratte]] (Literally "Rat"; the fact that they called it "land cruiser" rather than "tank" is in and of itself telling). Wanna know what it would have looked like? [[http://strangevehicles.greyfalcon.us/mauspic/ratte100.jpg Have fun]]. Note the soldier standing on top for scale.
*** Oh, it gets worse/better than that. Around the same time as the Ratte, they were also working on the Landkreuzer P. 1500 Monster, which would've been ''even bigger'', with a ''[[http://paradiselost522.250free.com/dora_color.jpg Dora gun]]'' mounted on it. Fortunately for the Axis (and to a ''much'' lesser extent, the Allies), Albert Speer realized how idiotic both projects were (no matter how heavy the armor is, a "land cruiser" would inherently be a large, slow target that Allied air power could just keep dropping bombs on until the thing died) and canceled them.
** French [[http://www.militaryfactory.com/armor/detail.asp?armor_id=282 Char 2C]]. 69 metric tons.
*** Big, but [[SubvertedTrope not exactly a land battleship]].
** The Soviet [[http://en.wikipedia.org/wiki/T-35 T-35]] probably qualifies - a veritable Games Workshop Tank with five turrets, but about as much use as you might expect. This one got into series, though soon canceled as obsolete.
*** This was based on the Earlier British [[http://en.wikipedia.org/wiki/Vickers_A1E1_Independent A1E1]], which was about as successful. Nor was the t-35 the only offshoot, for the Russians also built the T-28 and T-100, the British built the Medium Mk I, and Medium Mk III, and even the Germans got in on the act with the Neubaufahrzeug, though having a greater presence of mind, cancelled the idea soon after.
*** The Soviet [[http://en.wikipedia.org/wiki/T-28 T-28]], nicknamed ''Postivaunu'' (Stagecoach) by Finns in WinterWar. Formidable three-turreted monster, but an abysmal failure in practise.
** And then there's the [[http://www.tankmuseum.ru/p1.html IS-7]] heavy tank, which there were only three made, but actually had the 130mm S-70 naval cannon as a main weapon, in addition to no less than 8 machine guns as secondaries.
* The tank itself was initially considered this, to the point that the first one not only were armed with [[http://en.wikipedia.org/wiki/QF_6_pounder_Hotchkiss naval guns]], but they were originally developed and crewed by the ''Royal Navy'' (the British Army had decided the idea was impractical. Winston Churchill, then First Lord of the Admiralty, disagreed, and was proven right). Bonus point for originally being called ''landships'' before the name tank, chosen for secrecy (they told everyone, including the factory workers that built the first batch, they were mobile water tank for use in desert warfare in Mesopotamia), settled in.

[[/folder]]

[[folder: Anime and Manga ]]

* The ''Manga/{{Area 88}}'' manga features one of these, albeit on land: The land carrier moves on tracks, launches unmanned fighters, and hides itself by burrowing under the desert sand. Perhaps unsurprisingly, it is very difficult to cool.
* ''Franchise/{{Gundam}}'' and its multiple continuities had several of these serving to launch both aerial and amphibious mobile suits.
* ''MacrossZero'' had the Auerstadt as the Anti-UN forces' home base, launching both variable fighters and transforming mini-sub OCTOS.
* The ''Tuatha de Danaan'' from ''Lightnovel/FullMetalPanic''.
* The Dai-Gunkai of ''TengenToppaGurrenLagann''. Notable for being one of the few capable of creating ''its own ocean'' when it needs to travel over land.
* The ''Killer Whale''-class subs in ''VideoGame/SuperRobotWarsOriginalGeneration''. And if we add '''submersible flying space battleship''', there's also the ''Hagane'', ''Shirogane'', and ''Kurogane''.
* UNS ''Daedalus'' from ''SuperDimensionFortressMacross'' is a submersible HumongousMecha carrier.
* At one point, the team manager in ''{{Zoids}}: New Century'' brags that his already massive, snail-shaped Zoid carrier (overlapping somewhat with Land Battleship above) is capable of functioning underwater. Since it can launch flying Zoids, it pretty much counts.
* ''SuperAtragon'': Both the ''Ra'' and ''Liberty'' are submarine-battleships. The ''Ra'' carries and launches jet-powered sea planes.
* The Silvius from Last Exile Fam the Silver Wing. A aerial aircraft carrier that is capable of submerging for defense.
* In ''[[Anime/MobileSuitGundamSEED Gundam SEED]]'', the majority of Zaft's navy seems to be comprised of Vosgulov-class submersible mobile suit carriers.

[[folder: Video Games ]]

* ''VideoGame/SupremeCommander'' has the Atlantis-class submersible carrier for the UEF.
* ''AceCombat 5'' had a pair of these on the Yuktobanian side, although they were actually ballistic missile platforms that happened to be able to launch their own fighters for air defense. The first one, ''Scinfaxi'', had a rear takeoff area for Harriers and F-35s, while the Hrimfaxi had unmanned aircraft in vertical launch tubes (it can even launch them while submerged!).
* ''VideoGame/MetalGearSolid2'' gives us Arsenal Gear, a submersible HumongousMecha carrier.
* ''CrimsonSkies'' included a mission where a British submarine carrier, the HMS Barracuda, tries to attack and destroy their own base as well as destroy the Fortune Hunters and their zeppelin in order to hide evidence that they were planning an invasion of Hawaii.

[[/folder]]

[[folder: Real Life ]]

* Truth in Television once again. [[http://en.wikipedia.org/wiki/Submarine_aircraft_carrier Everyone from the United States to Japan has toyed with making these]] at one point. Japan actually deployed at least two dozen such subs of three different designs by the end of World War II. Several were tasked with "doomsday" attacks on the American mainland using biological weapons, but these were never successfully developed and the subs were reassigned to attack the Panama Canal. Before they could actually act on these orders, the war ended and they were seized by the United States. Rather than allow the technology to fall into Russian hands per war alliance treaties, the Navy chose to [[http://starbulletin.com/2005/03/20/news/story1.html scuttle the subs instead]]. One of these subs became part of the plot for the CliveCussler novel ''Black Wind'', in which it actually was carrying biological weapons.
** The British attempt (HMS M2) ended predictably badly as adding screen doors to a submarine sounds. While on a training exercise they opened the hangar doors too soon, which of course let the water in. It was lost with all hands.
* Also after the war both the US and USSR toyed with the idea of [[http://www.navy.mil/navydata/cno/n87/usw/issue_13/soviets_giants.html Amphibious Assault Submarines]] with capabilities ranging from submersible landing-ships up to Landing Helicopter Docks. The ''Tuatha de Danaan'' from ''LightNovel/FullMetalPanic'' is supposed to be a derivative of the Russian Typhoon class ballistic missile submarine, which is something that the Russians actually considered at the end of the Cold War.

* It doesn't come up in the average game of ''TabletopGame/{{Warhammer 40000}}'', but the Chimera infantry fighting vehicle used by the Imperial Guard is fully amphibious. The Land Raider used by Space Marines is a bit too heavy for that, but is so well-armored (and fully-pressurized) that one battle between the Space Wolves and Tau took place five miles underwater, on the ocean floor.

[[/folder]]

[[folder: Video Games ]]

* The Fatboy from ''VideoGame/SupremeCommander'' is also this. Ditto the Cybran Monkeylord spiderbot (which is more of a HumongousMecha). Supreme Commander loves this trope, with many more amphibious tanks and mecha to choose from. The UEF Percival, the Cybran Wagner, Brick, and Megalith, the Seraphim Othuum and Ythotha, and the Aeon Galactic Colossus are all perfectly happy going scuba diving. And if you count amphibious hovertanks, you get to count the UEF Riptide, the Seraphim Fobo, and the Aeon Aurora, Ascendant, Asylum, and Blaze.
** Preceding the Fatboy were the "Crock" and "Triton" tanks of ''TotalAnnihilation'', which also had hovercraft of its own.
** The Cybrans even have a battleship that ''sprouts legs'' and walks onto land.
* Franchise/MetalGear RAY. A giant, walking, swimming battletank, with an armor-piercing water cutter.
* The two BossInMookClothing tanks in ''{{Raiden}} II'''s second stage, and the Stage 3 boss in most installments.
* ''CommandAndConquerRedAlert3'' makes extensive use of amphibious units, as a way to make the inclusion of sea combat less frustrating and complex. The Empire of the Rising Sun has the [[MeaningfulName Tsunami Tank]], the Soviet Stingray is a boat that sprouts legs, while the Allies have the Assault Destroyer.

* TruthInTelevision yet again; several sorts of [[http://en.wikipedia.org/wiki/DD_tank amphibious tanks]] were designed, built and deployed in World War II. Likewise, a number of modern armored vehicles include amphibious capability, and most tanks can ford rivers using snorkels.
** A more extreme example is the German "Tauchpanzer" variant of the [[http://en.wikipedia.org/wiki/Panzer_IV Panzer IV]]: a tank capable of driving under 15 meters of water.
*** More extreme still was the gargantuan proposal ''Midgardsschlange'' for a 60,000 ton armoured, articulated ''train'' that could run on land, the bottom of the sea or even drill underground. It was designed by Nazi Germany in the 1930s and got to the vital asking for funding stage before the engineers involved were forced to go work on something sensible.
** The German ''[[http://en.wikipedia.org/wiki/Seeteufel Seeteufel]]'' design was an odd take on the "amphibious tank" concept, being practically a mini-submarine with tank threads. Proposed armament consisted of two torpedoes and a machine gun or a flamethrower. Not a practical design by any metric, but imagine the look on the Allied troops' faces when one of these would crawl up from a lake and start spouting flames at them.
** The P1000 Ratte And the P1500 monster previously mentioned under land battleship also would have had the ability to drive underwater up to a certain depth. This actually made sense for two reason, one both vehicles where designed partially using U-boat parts so adding more submarine features wasn't a terrific leap in cost. The other reason was that vehicles so heavy couldn't use conventional bridges, as they would crush them.
** Don't forget that the Japanese also used them, although [[http://en.wikipedia.org/wiki/Type_2_Ka-Mi theirs]] [[http://en.wikipedia.org/wiki/Type_3_Ka-Chi floated]] rather than driving submerged.
** The [[http://en.wikipedia.org/wiki/PT-76 PT-76]] is probably the most successful of modern amphibious tanks.
*** Arguably, its biggest success is in being cheap, lightweight, and armored enough to serve as an universal chassis for the whole lot of other Soviet vehicles, from self-propelled artillery to SAM launchers, adding more to its Military Mashup Machine status.
*** so, what you're saying is that In Soviet Russia, water full of Tank?
**** [[http://www.perekop.ru/history/nord-crimea-1941-172sd/attachment/perekop-1941-t37-tanks/ Sometimes]] [[http://www.cultinfo.ru/fulltext/1/001/010/001/252522462.jpg it]] [[http://www.panoramio.com/photo/7070048 is]]. Though [[http://www.diorama.ru/forum/files/thumbs/t_pantera_svastika.jpg not always]] the same [[http://mk-armour.narod.ru/2003/b_02/Photo_36.jpg way]].
** A quite successful historical amphibious tank was the [[http://en.wikipedia.org/wiki/DD_Sherman DD Sherman]] of WWII. The DD Sherman was a typical M4 Sherman medium tank with a collapsible skirt allowing it to float, and a drive modification operating a propeller providing it with propulsion while in the water (other tanks were similarly converted, but the Shermans were the most common). The main problem faced by the tanks was they were easily swamped and sunk during rough seas (as happened to the tanks deployed in the assault on Omaha Beach). However if managed properly, the tanks could prove devastatingly effective in support of amphibious operations (as occurred on the other beaches at Normandy). Other modifications for amphibious use, such as snorkels to allow operation while partially or even fully submerged, were also applied to the highly-adaptable Sherman.
** Remember that Maus we showed you on the Land Battleship section? It also counts as one of these. With air piped in through a snorken, another Maus powering it from the beach, they were literally designed to go across rivers because bridges would just collapse with them on top. Once it goes across, It then helps the other Maus through the river.

* The VF-0s in ''MacrossZero'' can, apparently, fly underwater. For short periods, at least. Ironically, this is the early version that runs on jet engines, as they hadn't got the alien fusion reactors working yet. There is an explicit shot of the intakes closing before it hits the surf, and it appears to be coasting.
* The Hammer Head [[{{Zoids}} Zoid]] can do this.
* To quote ''MarineBoy'''s theme, "Flying sub ahoy!"

* ''ComicBook/GoldDigger'' gave the villainous Night Flight an entire wing of these.
* From [[http://superdickery.com/index.php?option=com_content&view=category&layout=blog&id=33&Itemid=52&limitstart=64 an old comic book]].
* Turned UpToEleven by the ''[[Franchise/StarWarsExpandedUniverse Clone Wars]]'' comic books, with ''starships'' that operate underwater, crewed by Mon Calamari, appearing during the battle of Kamino. As their commander said while piloting one of the damn things:
-->'''Commander Merai''': [[WhatWereYouThinking What are they]] ''[[WhatWereYouThinking thinking]]'', defending a water world with ships that can't submerge?
* Top Cow's ''Fathom'' comics had one of these in testing, based on a recovered fighter from the race the titular character was from. Semi-F-14ish with variable wings, but mounted with a forward sweep design.

* Though not explicitly armed, the automated transports used by Syndrome in ''TheIncredibles'' get to Nomanisan Island by air... then go under water to dock.
* ''Film/SkyCaptainAndTheWorldOfTomorrow'' (2004) did this with submersible propeller planes.

* The [=KingFisher=] in the ''Series/DoctorWho'' novel ''The Indestructible Man'', a CaptainErsatz of everything Gerry Anderson ever did.
* Creator/EdgarRiceBurroughs' ''Beyond Thirty'' (alternate title ''The Lost Continent''): the protagonist is the captain of a Pan-American Navy "aero-sub" -- a submarine capable of AntiGravity flight. Sadly, he doesn't have his vessel throughout most of the story, having been thrown overboard by a mutineer in the first chapter.

[[folder: Live Action TV ]]

* The Puddle Jumpers from ''Series/StargateAtlantis'' take this to it's illogical conclusion: submersible spacecraft.
* The "Delta Flyer" from ''Series/StarTrekVoyager'', in similar fashion to the above mentioned "Puddle Jumpers", was modified in Season 5 Episode 9 "Thirty Days" to operate underwater. Making it a combination spacecraft/submersible. As with all shuttles in the Star Trek universe, it had atmospheric capability and space for multiple crew members, in effect making it a combination spacecraft/submersible/fighter/transport.
* The "[=SkyDiver=]" from ''{{UFO}}'' was a submarine whose entire front end was a JATO-boosted rocket plane called Sky One. At need, the [=SkyDiver=] would flood its rear ballast tanks until its bow pointed upward, and Sky One would launch...from ''under water''.
* The [[ExactlyWhatItSaysOnTheTin Flying Sub]] from ''Series/VoyageToTheBottomOfTheSea'' was the coolest thing on the show.
* ''Series/PowerRangersOperationOverdrive'' has the Special Hydro-Aero Recon Craft, aka [[FunWithAcronyms SHARC]]. ''Why'' you'd need your plane to drive on the surface of water is a good question, but it sure [[RuleOfCool looks awesome doing it]].
* ''Series/JyudenSentaiKyoryuger'' has Plezuon. This is the category it ''best'' fits, but really, where can't it go? Based on a plesiosaur, it was born/made for underwater use, but it was refitted for ''space'' travel. Its first partner even has the SpaceIsAnOcean metaphor as part of his roll call phrase; the seas of the earth and the sea of stars belong to "[[InTheNameOfTheMoon the marine hero, Kyoryu Violet]]!" (Its humanoid transformation enables land combat, but that's sorta cheating.)

* A number of vehicles in the ''{{Rifts}}'' Underseas sourcebook.
* The system defence boats of ''{{Traveller}}'' are capable of flying in space and in atmosphere and can go underwater, at least in the ''{{GURPS}}'' version. It helps that the vehicle rules of ''{{GURPS}}'' practically ''invite'' people to design vehicles that fit this trope.
** And they were pure eeeeevil in 3rd edition. No RPG should have make the player draw a square root.
** In defence of ''GURPS Vehicles'', it doesn't expect people to be doing this in the middle of a session of regular play. The ongoing design example from the book, incidentally, is more than worthy of inclusion on this page - a FlyingCar (kept aloft by ImportedAlienPhlebotinum and propelled by a jet engine, which can also give it a bit of extra speed on land) that's also a submarine, has military-grade electronics and is armed with concealed machine guns. Film/JamesBond, eat your heart out.

[[folder: Video Games ]]

* Almost all scrolling shooters allow the player's air or spacecraft to fly underwater without consequence.
* Although ''VideoGame/StarFox64'' had a separate submarine for the underwater mission, Arwings and other starfighters in ''Star Fox Command'' can do this.
** The unreleased ''Starfox 2'' also counts when fighting in the seas of Fortuna, but it's more like a jet fighter that turns into a submersible mecha that swims.
* ''CommandAndConquerRedAlert3'''s [[http://cnc.wikia.com/wiki/Sea-Wing Sea-Wing]] is a submersible ambush jet fighter.
* ''{{XCOM}}: Terror from the Deep'', the second XCOM game, had the player fighting Unidentified Submersible Objects (ie, [=UFO=]s that could go underwater) with a small fleet of their own submarine-jets.
* ''{{Elite}}'' had the Moray Star Boat, because aquatic species need to get shot at by SpacePirates too.
* Possibly an unintentional example in the Tiny Bronco in ''FinalFantasyVII'', a plane that, when its engines are crippled by gunfire, is used by the party as a boat.
* Stage 2-1 of ''{{Contra}}: Shattered Soldier'' features a submarine that transforms into a giant VTOL gunship.
* ''Videogame/MechWarrior Living Legends''' [[SpacePlane aerospace fighters]] are capable of flying in space, inside atmospheres, or underwater, with no performance drops.
* The planes of ''VideoGame/SineMora'' are prop-driven rather than jets, but can convert to underwater movement simply by flipping their wings (so the props face backwards instead of forwards) and seem to function just as well underwater as they do in the air.

[[folder: Western Animation ]]

* ''GIJoe'' had the S.H.A.R.C. (Submersible High-speed Attack and Reconnaissance Craft.) The [[MerchandiseDriven toy company]] intended it to be strictly a submarine, but in playtesting, kids started treating the toy as an aircraft. So now it's both.
* ''The New Adventures of He-Man'' had a vehicle capable of submersion, atomspheric flight and space flight called Astrosub.
* The triple-changer Broadside in ''Franchise/TransformersGeneration1'' transforms into both an aircraft carrier and a jet.
* Dr. Claw's CoolCar in ''InspectorGadget'' can turn into a jet or a submarine.

* The Soviet Union designed a [[http://en.wikipedia.org/wiki/Flying_submarine flying submarine]] in the 1930s, but it was never actually built.
* The USA had [[http://davidszondy.com/future/Flight/flying_sub.htm a similar idea]].
* The United Kingdom messed around a bit with a seaplane jet fighter, the [[https://en.wikipedia.org/wiki/Saunders-Roe_SR.A/1 Saunders-Roe SR.A/1]], and the Americans similarly worked on the [[https://en.wikipedia.org/wiki/F2Y_Sea_Dart Convair F2Y Sea Dart]], but both nations moved away from seaplane fighters once carrier-born fighter jets became practical.

[[folder:Mobile Factory]]
The is [[ExactlyWhatItSaysOnTheTin exactly what it sounds like]]. A factory capable of pumping out mass-produced (often robotic drone) war machines, combat-ready right off the assembly line. This is usually its primary purpose, though it may have other weapons.

[[/folder]]

[[folder: Anime and Manga ]]

* The ''SuperDimensionFortressMacross'' was able to build new and replacement mecha (at least it could in ''{{Robotech}}''), not to mention the Zentraedi/Robotech Master factory sattelite. Each of the colony fleets shown in ''Macross7'' and ''MacrossFrontier'' included factory ships as well.
* The [[TengenToppaGurrenLagann Chouginga Dai-Gurren]] has the production facilities and raw materials to build several dozen city-sized [[HumongousMecha giant robots]] in a matter of days.

[[/folder]]

[[folder: Literature ]]

* The [[DarkEmpire World Devastators]] from the ''Franchise/StarWarsExpandedUniverse'' not only did this, but ate the planets they were attacking, then refined the raw materials. If given enough time, a fleet of World Devastators could consume the entirety of a planet and convert it into new war machines. Including ''more World Devastators''.
** EVS Construction Droids are walking factories that tear apart buildings on one end and reassemble them at the other. They're not strictly military, though there's that one time [[XWingSeries Rogue Squadron]] hijacked one and went on a {{Kaiju}}-style rampage to evacuate a section of an enemy city before it could be {{Kill Sat}}ted. But that definitely wasn't the intended purpose.
* The General Systems Vehicles of [[Creator/IainBanks Iain M. Banks]]'s [[Literature/TheCulture Culture]] novels qualify as, among other things, mobile factories. These ships are large enough to be home to billions of people and can crank out other massive ships, as described in '''Excession''.

* The Cylon Resurrection Ship in ''Series/BattlestarGalacticaReimagined'' is a mobile ''people'' factory.
** More ''Galactica:'' Tyrol actually had his crew build a whole Viper out of spare parts onboard the ''Galactica,'' and a damn good one at that. In fact, due to the availability of pretty much any material ''but'' metal, it was also their only stealth ship.
** The civilian ships also had sewage treatment ships and mining ships.
** And the ''Pegasus'' had been designed with a Viper factory on board.
** Conversely, in the original Galactica series, there seemed to be a shortage of shuttlecraft. Every shuttle in the original series had the same markings (GAL 356) even when the shuttle came from the Pegasus.
* The seed ships in ''Series/StargateUniverse'' travel the universe building Stargates and placing them on habitable worlds
* The ''Series/StarTrekVoyager'' crew used their MatterReplicator to replace the shuttles they frequently lost. Eventually they even designed a new shuttle class.

[[folder: Video Games ]]

* Aircraft carriers in many RealTimeStrategy games usually operate like this.
* The restored Necron Monolith from ''{{Dawn of War}}''. When the Necron's headquarters building is brought fully back online, it transforms from an ominous black pyramid of doom into an evil floating pyramid of doom and green lightning that can suddenly materialize right in the middle of your base. While it holds the award for the single slowest unit in the entire game, it can teleport, has a gigantic cannon, and regenerates. As if that wasn't enough, it still maintains the ability to produce units.
* ''VideoGame/SupremeCommander'''s Fatboy is able to construct military units as well. (For those keeping score, that makes the Fatboy a Submersible Land Battleship Carrier (it has a landing pad) that can construct its own support force. ''And'' it mounts heavy-duty shield generators. Though it's so enormous it occupies most of the shielded area, leaving little room for its support force.)
** As well as all of its carriers building aircraft, ''VideoGame/SupremeCommander'' also has: the Tempest, a Submersible Battleship that constructs smaller ships, although it can't travel on land; the Cybran Megalith, a carrier that can build select Cybran land units, and the Aeon Czar, which is a ''flying'' mobile factory and AirborneAircraftCarrier armed with a WaveMotionGun, flak cannons, AAM, and depth charges.
* The base of operations for King K Rool in ''DonkeyKong64'' houses a BFG and produces its own mooks in its bottom.
* The Protoss Carrier in ''VideoGame/StarCraft'' manufactures and launches its own robotic interceptors. The Reaver similarly builds Scarab drones that are used as self-guided bombs.
** The Carrier returns in ''StarCraftII'', the Terrans gain the Raven, and the Zerg the Brood Lord. Could also be broadly applied to Terrans as a whole, since their major production buildings can move, although they can't produce units while doing so.
* A mainstay of the ''CommandAndConquer'' games ([[InNameOnly excluding]] ''[[CommandAndConquer Generals]]'') is the Mobile Construction Vehicle, a slow-as-molasses, helpless unit that can deploy into a Construction Yard capable of building an entire base from scratch in a matter of seconds. In later titles they gained the ability to pack up and move elsewhere to set up new bases.
** In the ''CommandAndConquerTiberianSun'' expansion, ''Firestorm'', both factions gained mobile factory units that could deploy into unit-producing buildings similar to the MCV; particularly dangerous when paired with the Brotherhood of Nod's mobile cloaking generators.
* All capital ships (and the carrier-class non-capital ships) are capable of constructing their own fighter escorts in ''SinsOfASolarEmpire''. This is subverted (or averted?) for the Advent faction, as their fighters are merely psionic constructs.
* The Mothership in the ''VideoGame/{{Homeworld}}'' games can construct just about any other type of warship type, depending on the game. In ''Homeworld 1'', it can build any and every type of ship up to Heavy Cruiser; in ''Homeworld Cataclysm'', the Command Ship is also capable of constructing every other ship type up to Dreadnought. ''Homeworld 2'' is where it branches off, where the Mothership is capable of constructing only up to Destroyers; to construct anything bigger, it has to call in a Shipyard, which is capable of building anything up to the biggest unit, the Battlecruiser. Carriers themselves are capable of constructing small and medium-sized craft (up to Frigates). The downside is that the Mothership has no maneuverability to speak of (in the first game it cannot move at all), and its own weaponry is in the peashooter range.
** Partially justified in the first game's campaign, as the Mothership was supposed to be mobile, but [[spoiler:the destruction of Kharak]] forced it to begin its journey before the engines were complete (it uses hyperspace jumps to go from one mission to the next). The resulting inability to avoid even slow-moving threats becomes a major plot point.
* The carrier Antaeus in ''HostileWaters'' has a large number of nanobots that can create a helicopter, tank, or a few similar things in about a second. You can only have a dozen or so tanks/helicopters/whatever active at a time but when you lose one you can replace it very quickly.
* One never-ending source of Mooks in ''Jak 3'' is the KG War Factory, endlessly producing robots of the former Krimzon Guard. Granted, why they didn't use this machine in the previous game to put the whole city on lockdown while trying to take out the Underground when they were finally making a real impact, is completely unknown.
* The only way to employ Seaplanes in ''AdvanceWars: Days of Ruin'' is to construct them in Carriers.
* ''HaloWars'' has the Elephant, which is a mobile barracks.
* The majority of Night Elf buildings in ''WarcraftIII'' are mobile, and while they can't perform their primary function while moving, they ''can'' fight.
* The ''Xtended Terran Conflict'' GameMod for ''[[VideoGame/{{X}} X3 Terran Conflict]]'' has the M7D Drone Frigate class of ships, which will build high-powered combat drones equivalent to a M4-class interceptor. Loses are quickly replaced by building more drones. The frigates are fairly fast, but have mediocre shielding and firepower. Other factory ships exist, such as the Goner Aran, a mobile shipyard which can build a wide variety of ships, plus the standard factory ships which produce weapons/shields/ore/energy/crystals/food.

* Some starships in ''Webcomic/SchlockMercenary'' are equipped with [[{{Nanomachines}} Fabbers]] big enough to create other starships. At one point the main characters acquire a particularly big one, and consider fitting it with engines and crew quarters and naming it ''The Scrapyard of Insufferable Arrogance''. (mocking [[ScaryDogmaticAliens Ob'enn]] naming schemes)

* While not a factory, real naval ships have machine tools on board to fix broken equipment. You can do quite a lot of work on a real aircraft carrier.
* The Soviet retreat behind the Urals in UsefulNotes/WorldWarTwo, the largest industrial migration in history, is about as close as we have ever come to this trope in real life. Entire factories were literally uprooted, stuck on railway cars and sent East.

* At some point, most silly works will include efforts to make a flying tank. Sometimes this will be to just slap wings on that ever-so-aerodynamic thing, the main battle (or light) tank.
** That would include the A-Gears in ''AirRivals'', which are not so much an aircraft but a ''flying hovercraft tank'' that's capable to not only traverse land and aquatic terrains, but also ''latch itself onto edges of ravines and cliffs''. To hammer the point home, one of the equippable armors had wings on it. Predictably though, its survivability drops down once it actually does take to the air, especially when pitted against other, more fighter-oriented Gears...
** The Landmaster in ''VideoGame/StarFox'' is a tank with boosters which allow it to roll, hover and generally be much more maneuverable than a regular tank.
** The Soviets attempted to build a flying tank during UsefulNotes/WorldWarII as an attempt to bring a tank very quickly into battle. Basically a tank with wings and tail strapped to it, it's more of a glider - a bomber would tow it into the air, then it would sail into the battle field, land, ditch its wings and tail, and start blasting away at the enemy. It was cancelled because they didn't have a towing plane with enough engine power to haul the hulking thing into the air fast enough.
*** They eventually ''did'' succeed in building a flying tank during the Cold War; aka the Hind helicopter.
** Imperial tanks in Literature/EmpireFromTheAshes use a fully-functional gravitonic drive, and can hit Mach 2 in atmosphere. [[LightningBruiser They are also heavily shielded]], and capable of deploying more conventional tracks for increased stability and decreased power budget.
** Hovertanks in ''Webcomic/SchlockMercenary'' are essentially small spacecraft with big guns mounted on the front end. But they are still called tanks.
** ''VideoGame/ToySoldiers Cold War'' features one as a boss fight. It was based of the real life Antonov A-40; which was designed to be towed behind a plane and then let loose to glide to it's designation. A prototype was built and it didn't go much further than that.
** Put in the flying cars cheat into GTA 3 and the Rhino tank will fly, propelled by recoil from shooting backwards. It's arguably easier to fly than the clipped-winged Dodo. Works in Vice City too, where it can fly higher than helicopters and planes.

* HumongousMecha in most Real Robot settings seem to be mashups of your average infantry soldier and an armored tank or jet fighter.
* The Mobile Armours of ''Anime/MobileSuitGundam'' are often even straighter examples: Large non-humanoid units, built with the same technology as Mobile Suits, that acted as more specific machines like submarines, flying tanks, land battleships, and more.
** Don't forget the Magella Attack! It's a tank whose turret can detach and fly. A ''CoolPlane'' it's not- apparently a tiny plane with a gigantic tank cannon on the front isn't very practical.
** Zoids are the animal versions of the same principle.
* The Grandia Tank in ''Nadia'' is a triple threat: a tank on land, an airship, and a paddle-wheeled boat. It runs off [[SteamPunk steam with punch card controls!]]
* ''CodeGeass'' has airships that are submersible, a HumongousMecha that turns into a fighter jet-thingie, and another that turns into a stealth submarine ''as well'' as being a jet fighter. Extra points for the latter being the main character's personal unit.

Eventually, it goes over the ocean, to the relief of the commander: 'Call the Navy!'

* DaleBrown's EB-52 Megafortress and other machines that fall into the CoolPlane category are essentially mash-ups of heavy bombers and fighters. Since in real-life the most difficult changes would involve changing some programming lines in a radar's software and adapting the bomb bay to carry an ''[[MacrossMissileMassacre obscene]]'' [[MacrossMissileMassacre amount air-to-air missiles]], this concept [[http://en.wikipedia.org/wiki/B-1_Lancer#B-1R just might]] become TruthInTelevision as well.
* Navy pinnaces in the ''Literature/HonorHarrington'' series are the bastard children of the space shuttle and the B-1R mentioned above, scaled up to the size of a 747. They are interplanetary space craft, SpaceMarine assault ships and fighter-bombers rolled into one.
* From the Creator/EEDocSmith SpaceOpera ''[[Literature/{{Lensman}} First Lensman]]'':
-->The vehicle, while slow, could go -- literally -- anywhere. It had a cigar-shaped body of magnalloy; it had big, soft, tough tires; it had cleated tracks; it had air- and water- propellers; it had folding wings; it had driving, braking, and steering jets. It could traverse the deserts of Mars, the oceans and swamps of Venus, the crevassed glaciers of Earth, the jagged, frigid surface of an iron asteroid, and the cratered, fluffy topography of the moon; if not with equal speed, at least with equal safety.
* Similar to the ''Lensman'' example above, the ''Literature/PerryRhodan'' universe gives us the so-called 'Shift' -- an amphibious, flight-capable, yet still tracked tank usually equipped with DeflectorShields and energy weapons that can operate and fight in pretty much any environment, including some of the more extreme alien ones.
* In ''Literature/TheCourseOfEmpire'', the hastily cobbled together spaceships used in the fight against the Ekhat invasion of Earth are human missile submarines - with two rows of four tank turrets in place of most of the missile launchers - converted into spacecraft with Jao technology.

* In ''Franchise/StarTrek'', Federation ships appear to mix the functions of warship, science vessel, deep space exploration ship, and diplomatic vessel all into a single hull. This is epitomized in ''Series/StarTrekTheNextGeneration'' with the Galaxy class of starship (including, naturally, the flagship ''Enterprise''), which is all of the above ''[[UpToEleven plus what is functionally a small town]]'', complete with schools, recreation areas, and a bar. The Federation also seems to have an aversion to calling their ships "warships" despite the fact that they have more than sufficient shields and firepower to stand up to the dedicated warship designs used by other spacefaring civilizations. (This policy is reversed during [[Series/StarTrekDeepSpaceNine the Dominion War]]).
** ''Film/StarTrekIntoDarkness'' adds submersible to that last, though that might be just something in the altered timeline.
* The ''[[Series/{{Andromeda}} Andromeda Ascendant]]'' takes large parts of TheBattlestar, and adds troop transport, science vessel, mobile factory, diplomatic vessel, planet killer and ''star destroyer'' to boot. All such ''Glorious Heritage''-class heavy cruisers have such capabilities.

* Some {{Transformers}} have multiple forms, resulting in things like this. Perhaps most well-known is the Decepticon Triple-Changer Blitzwing, whose alternate modes are a [=MiG-25=] and a Type-74 tank.

** Anything with TransformingMecha really, when you basically have tanks that turn into mechs. Literally when you bring CombiningMecha into the equation.
* The SHIELD Helicarrier shows up in pretty much every Marvel Comics-based animated series. ''WesternAnimation.UltimateSpiderMan'' takes it a step further by having it wrecked and rebuilt as the Tri-Carrier, which is able to ''split'' into the spacefaring Astro-Carrier, the submersible Aqua-Carrier, and the flying Dragon-Carrier.

* In the ''VideoGame/{{Homeworld}}'' games, your mothership is a space factory/carrier, able to manufacture everything else in your fleet and house all of its smaller craft, while also able to maneuver(or even make hyperspace jumps) to any part of the battle area like any other ship. However in the original game, on its own, it's still fairly vulnerable.
** The Carrier-class ships from the first game also functioned as factory/carriers, but weren't able to build the larger ships (like Carriers) and were much faster and more maneuverable than the Mothership.
** In the ''Cataclysm'' expansion, it's possible to add "battleship" to the number of roles it fills. While still fairly vulnerable, it was much more capable of fending off fighters and small capital ships on its own. With a particular upgrade, they could even wipe out enemy fleets.
** In ''Homeworld 2'', though, the Mothership went back to being vulnerable to pretty much anything, and ''another'' factory/carrier ship, the Shipyard, was added. It could build the largest ships in the game, which the regular Mothership couldn't, but was even slower and less maneuverable.
* ''FinalFantasyVIII'' features the main protagonists and antagonists using a mash-up of guns and [[KatanasAreJustBetter swords]]. The user would load a cartridge into the "gun" part and "fire," which would cause the blade to vibrate and [[RuleofCool magnify damage]].
** RealLife: There were real examples of Sword-Guns, though they weren't very popular. Commonly, they involved a knife/revolver combination.
** Of course, the rifle bayonet is a somewhat more successful example of a gun/edged weapon hybrid.
** While not edged, the powerhead (aka "shark stick" or "bang stick") uses a similar principle in a "jab with a stick" fashion.
*** Parisian hoodlums who called themselves the "Apaches" had weapons that could be used as a dagger, a revolver, or a set of brass knuckles.
*** Some [[UpperClassTwit upstanding gentlemen]] in the seventeenth century created cutlery pistols - as in a knife-pistol and a ''fork'' pistol.
** The 'gunblade' of Final Fantasy VIII is actually more akin to the [[{{Vibroweapon}} vibroblade]] concept, which is quite popular.
* ''VideoGame/{{Starcraft}}'s'' Terran siege tank, which switches from main battle tank to artillery platform.
** Then there's the Viking in ''VideoGame/StarcraftII'', which switches from mecha to space superiority fighter.
* ''CommandAndConquer Red Alert 3'' is pretty much in love with this trope, especially the gadget-heavy Empire. Between the examples listed and others, there are very few units that don't qualify. Even most buildings can be planted in the water, so long as the unit they produce can exist on water. The Empire don't even have an air factory, since every single flier they field transforms from a vehicle, ship, or infantry.
* To a lesser extent, the Sonic the Hedgehog titles. The easiest example being the Egg Carrier, having a runway on the front of it, robot construction rooms in the interior (complete with "training" areas), as well as a couple entire stages within it.
* ''ChromeHounds''. Yes, the titular [[AMechByAnyOtherName Hounds]] are supposedly HumongousMecha, they're more like ''tanks''. And by that I mean, a hound is probably a wall of Artillery cannons, Battleship guns, hulking armor, [[MoreDakka machine guns that turn M1-Abrams into swiss cheese]], on anything from humanoid bipeds to tanks. ([[RealRobot Oh, and tanks/wheels tend to be a bit faster.]]) and the cockpits range from bridges of ships to jet-fighter cockpits.
* ''VideoGame/MetalGearSolid3's'' ''Shagohod'' was a tank/hovercraft/ICBM launcher hybrid. With legs. They were just forelimbs, meaning it couldn't walk upright like the titular Metal Gear, so it compensated with a pair of Archimedes' screws. Have we mentioned it was rocket-boosted?
* ''VideoGame/ShinMegamiTenseiStrangeJourney'''s unique model of dimensional-hopping warship model definitely counts. It has fabrication labs for weapons and technology development, outer weapons systems, plasma shields, hospital sectors, an AI navigator, and, oh, yes, ''rocket-boosted VTOL capabilities''.
* ''VideoGame/MassEffect3'': Reapers can fight planetside almost as well as they can fight in space, "standing" on their front tentacles and acting as a gigantic, mobile artillery platform. The only drawback is that it weakens their shields somewhat (though not nearly enough to make a difference), as they have to divert extra energy to the mass effect fields keeping them from falling over or [[SquareCubeLaw collapsing under their own weight]] while in a gravity well. They also count as Mobile Factories, of a sort, as they can take in living or dead lifeforms and turn them into Husks, making them into Reaper ground troops.

* Arguably, the original aircraft carrier was a working real-life example of this, attempting to combine an airbase with a ship.
** ...and while we're at it: the AirborneAircraftCarrier in all its many incarnations.
** British carriers of UsefulNotes/WorldWarOne, many of which were conversions of warships already in service, tended towards a different hybrid status. HMS Vindictive, converted from a cruiser, carried five 7.5in guns; the former battleship HMS Furious, meanwhile, witnessed the first successful landing of an aircraft on a moving ship while still mounting a single 18in gun aft. The concept was revived (albeit briefly) in 1940, when lack of carriers and need for airborne protection led to suggestions that battleships under construction should be redesigned to carry ten fighters.
*** Also worthy of mention are the M-class submarines, which began as a project to fit a 12in battleship gun on a submarine, and which ended up in one case as a submarine aircraft carrier.
*** Partly to get around the Second London Naval Treaty and partly because they just did things differently, the Soviet Union built four "aviation cruisers", essentially VTOL aircraft carriers with anti-shipping missiles built in. The VTOL aircraft, the Yak-38 "Forger" was spectacularly poor. The current sole Russian carrier, the ''Admiral Kuznetsov'' is also an example, albeit a full-length one with Su-33 fighters on, since it has vertical launchers for heavy anti-ship missiles hidden underneath the flight deck. The Russian Navy currently intends to strip those out and expand the hanger whenever they have the time and money to do a full refit.
*** Due to a shortage of carriers after the Battle of Midway, the Imperial Japanese navy converted the battleships Ise and Hyuga into carrier-battleships, removing the rear guns and installing flight decks. The design was not successful. The shortage of both planes and pilots by that point didn't help, but even if there had been enough to go around the fact that only seaplanes (inherently slower and less agile than conventional fighters due to the drag from their pontoons) could be properly operated would have still made them ineffective.
*** Most of these belong in the Battlestar category.
** An Amphibious Assault Ship is probably as close as practical towards several mash-ups into a single ship, taking on the functions of aircraft carrier, troop transport/beach assault ship, command ship, and - when some earlier designs still had decent-sized guns[[note]]With the introduction of the [=LCAC=] landing hovercraft and the V-22 Osprey tilt-rotor, the US Navy stopped putting guns on the newer designs because an amphibious assault will now be launched from a hundred miles or so offshore, well out of gun range.[[/note]] - bombardment ship.
*** Probably no more of a mash-up than the [=LSTs=] ('Landing Ship Tank's) of WWII, which had to be good in both deep and shallow water.
** Many battleships carried seaplanes; today, many destroyers and cruisers carry helicopters, as did the ''Iowa'' class battleships when they were brought back into service in TheEighties.
*** Many battleships were built before radar was around, so the seaplanes served the scouting function. Now that we have radar, the seaplanes have been replaced by helicopters to serve in the ASW role.
*** And then there [[http://www.damninteresting.com/submersible-aircraft-carriers were]] [[http://www.regulus-missile.com/SubmarineWings.htm many]] [[http://www.navalofficer.com.au/index.php?option=com_content&view=article&id=288:carriersub&catid=44:submarines1&Itemid=80 attempts]] to carry planes on a submarine, including Japanese "Sen Toku" with 3 torpedo-bombers.
** The unlucky French submarine [[http://en.wikipedia.org/wiki/Surcouf_(N_N_3) ''Surcouf'']]. Touted as an "underwater cruiser" it was armed with ''two'' 203mm guns in a forward turret and 10 or 12 (accounts differ) torpedo tubes, and housed a scout seaplane in a hangar below decks to use the full range of those guns. It was also armed with a significant number of AA cannons and machine guns. However it never saw action: it was accidentally rammed by a US freighter off the coast of Cuba and sank with all hands.
* The Israeli [[TankGoodness Merkava]] is arguably a mild example, armed as well as any other main battle tank in the field AND capable of doubling as an APC. Some are even equipped as [[DeadlyDoctor ambulances]]. In practice, though, the Merkava's rear compartment is normally used to carry extra ammo for the main gun. On the other hand, it made adapting the Merkava chassis into a pure APC (something that would be virtually impossible with most modern main battle tanks) not only plausible but easy, resulting in the Namer (contraction of "Nagmash" (Hebrew for APC) and "Merkava"), the most heavily armored APC in current use.
* Successful real life example with the Russian MI-24 Hind helicopter, which was designed to combine the roles of a transport and attack helicopter. Basically, it's a flying [[AwesomePersonnelCarrier Infantry Fighting Vehicle]]. However, serving as a transport made it bigger and less maneuverable than a pure attack helicopter. Though in terms of pure straight-line speed it's still the fastest attack helicopter to ever go beyond the prototype stage.
* [[http://www.diseno-art.com/encyclopedia/strange_vehicles/x-wing.html RSRA X-Wing]]. (No, not [[Franchise/StarWars that X-Wing]].) It's a plane! It's a helicopter! It's a plane ''and'' a helicopter!
* See [[http://www.amazon.com/My-Tank-Fight-Zack-Parsons/dp/0806527587/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1205083504&sr=8-1 My Tank is Fight!]] for a look at flying tank ideas, among other Military Mashup Machine concepts from RealLife.
* Several countries [[http://en.wikipedia.org/wiki/Winged_tank experimented]] with flying tanks in ''UsefulNotes/WorldWarII'', some included in the book above.
** If any practical real-world aircraft could get away with calling itself a flying tank, the [[RealLife/CoolPlane A-10]] is it. Also, one even successfully shot down an Iraqi fighter with its [[GatlingGood Avenger rotary cannon]] during the UsefulNotes/GulfWar, even though not designed for air-to-air combat.
* Wouldn't be a complete article without mentioning [[http://en.wikipedia.org/wiki/Lockheed_AC-130 the AC-130]]. With the weapons load including a ''105mm howitzer'' it's is informally classified as a flying artillery platform. I mean just look at that thing.
* The AC-130 is cool, but similar attempt was done on at least two [[http://www.stormbirds.net/variants262a1aU4.htm ME262]], the Me262 A-1a/U4 variant, with 50mm Anti-tank cannon fitted on its nose. Consider WWII have light tanks with smaller cannons.
* The Boulton Paul Defiant: a WWII RAF fighter/interceptor with a machine gun turret behind the cockpit and no forward armament[[note]] the turret guns ''could'' be triggered by the pilot, with the intention of allowing forward fire as in a standard fighter, but the cockpit was in the way, which forced the guns to elevate by 19 degrees when pointed forward. It would have been difficult to design a gunsight that would handle this, so the pilot ended up without one[[/note]]. The weight of the turret and gunner seriously impacted on the aircraft’s performance compared to other fighters, and it was still vulnerable to attack from beneath or dead ahead. Initially, the Defiant brought down quite a few rather surprised Luftwaffe pilots, [[note]]many of whom confused it with the similarly-shaped Hawker Hurricane[[/note]] but once they knew what they were dealing with, they made mincemeat of it. [[note]]The turret fighter concept had worked rather well back in the WWI era, with a number of successful models, particularly the RAF’s Bristol F.2 Fighter, which the Defiant was intended to emulate. However, that was the era of biplanes, open cockpits, top speeds a quarter of those in the WWII era, and rather more forgiving aerodynamics. Which, for instance, allowed the Bristol F.2 to be equipped with both a turret ''and'' a forward machine gun. By the time the practical limitations of the turret fighter in the WWII closed-cockpit arena had become apparent, a number of turreted versions of successful fighters (such as the Mosquito) were in the process of being designed or commissioned. None made it into service.[[/note]] It proved a very successful night fighter, as it could shoot the German bombers from underneath, and provided the backbone of the RAF night fighter command before the advent of Bristol Beaufighter.
* Its a corvette! It's a heli carrier! It's a Landing ship! No it's a [[http://en.wikipedia.org/wiki/USS_Freedom_(LCS-1) Littoral combat ship!]]
* [[https://en.wikipedia.org/wiki/Flying_boat Flying Boats]], being a fairly straightforward combination of a boat and an airplane. For decades, these planes were used as long range transports, bombers, and scouts, as they did not require a prepared runway to land and refuel, as long as there was a sizeable enough body of calm water to land on. Flying Boats which were unable to fly due to damage or being overloaded could often simply sail like a boat, using their engines to push them along and their rudder to steer, as happened with a Catalina flying boat that ended up taking on 56 shipwrecked sailors after the sinking of the USS ''Indianapolis''. Various models are still in use to this day, although their popularity faded with the development of proper long-ranged land-based planes, and in particular Jet Liners such as the Boeing 767.
* A much less conventional hybrid between a plane and a boat is the ground effect vehicle, also known as ekranoplanes. These often look like strange flying boats with short wings but rely on the ground effect principle, which basically they ride on a cushion of air that forms between the wings and the ground (or the sea). While smaller ground effect vehicles are basically high speed hovercrafts, the larger are often solely relegated to the water and often function as high speed cargo haulers. It still isn't decided if they technically planes or ships, which is important as they could be considered the fastest ships or the heaviest airplanes.
