''Down Periscope'' is a 1996 comedy movie starring KelseyGrammer as Lieutenant Commander Thomas Dodge of the United States Navy. Though considered by many to be a talented officer, he has been denied command of his own submarine twice for his... [[MilitaryMaverick cavalier command style]]. A third denial will forever bar him from commanding a submarine.

But Vice Admiral Winslow has a feeling that summarily dismissing an officer like Dodge would be a bad thing, and has come up with a method of proving it -- a war game which pits the USS ''Stingray'', one of the Navy's last remaining diesel submarines, against the East Coast nuclear navy. Dodge's assignment -- simulate a terrorist strike against Charleston and Norfolk.

However, his opponent, Rear Admiral Graham, doesn't think the Navy needs irrepressible screwups like Dodge, and is willing to [[TheNeidermeyer stretch the rules to the breaking point]] to prove it -- starting by giving said screwup [[RagtagBunchOfMisfits the crew he believes such a screwup deserves]] -- ultimately a mistake that will make a laughing stock of the U.S. nuclear navy, as Admiral Winslow has explicitly ordered Dodge to "think like a pirate" to show that most of the world doesn't play by the book, and that's exactly what Dodge is going to do.

Notably Lt. Emily Lake (Lauren Holly) is supposed to be the first female submarine crew member in the history of the United States Navy. She is a Diving Officer.

The film is a parody of ''Up Periscope'' and other films in the submarine-film genre.
!!Examples of:

* AccidentalInnuendo: See HehHehYouSaidX below.[[invoked]]
* AccidentalMisnaming: Nitro can never get Admiral Graham's name right.
* ArtisticLicenseMilitary: There's plenty of stuff that has those actually familiar with the RealLife US Submarine Service laughing not only at the intentional comedy that's a surprisingly accurate reflection of submariners, but the unintentional variety as well. While some of the inaccuracies are due to writer ignorance, and some are due to RuleOfCool or convenience to the plot, some of the issues surrounding the USS ''Orlando'' can be chalked up to the film production staff not having access to classified USN information.
* TheAllegedCar: The Stingray. It was chosen for the war game ''because'' of its obsolete, decrepit nature.
* BehindTheBlack: When Pascal is walking the plank, Lt. Lake doesn't seem to notice Pascal is going to fall safely into a fishing net until he actually does so.
* BlunderCorrectingImpulse: While the submarine is [[spoiler:passing between the propellers of a larger ship]] Dodge gives less than perfect orders to get Lt. Lake out of her crisis of ability.
* BrickJoke: When he first meets his crew, Dodge gets Stepanek to settle down by informing him that "if I throw you off, it'll be in the middle of the Atlantic." Later in the film, Dodge does in fact throw an insubordinate member of his crew off of the ''Stingray'' in the middle of the Atlantic - but it's not Stepanek, it's [[spoiler:Pascal]], and [[spoiler:he's tossed onto the waiting net of a helpful fishing boat rather than into the water]].
* BunnyEarsLawyer: Most of the crew fit this trope, [[RagtagBunchOfMisfits which is how they ended up on the ship to begin with]], starting with their Commanding Officer, LCDR Dodge. Both on and off the job, he's an immature goofball, but he also shows that immature does not necessarily mean irresponsible. His antics are never shown to actually affect his job performance, he gets along well with his subordinates, and he whips a derelict rustbucket submarine into seaworthiness over the course of a montage.
* ChekhovsSkill: Sonar's attempts to mimic whales by recording their calls.
* ChekhovsGun: Two live torpedoes.
* TheChewToy: Nitro has to endure electric currents through his body ''several times'', just so Dodge can talk to somebody.
* {{Cloudcuckoolander}}: Nitro, due to having "absorbed a lot of voltage" in his electrical career. His EstablishingCharacterMoment is basically him testing loose wires for voltages ''without a meter''. 'Sonar' Lovacelli is, to a lesser degree, one as well.
* ComicallyMissingThePoint: When the ''Stingray'' makes its first dive down to 500 feet, Chief Engineer Howard attaches a string to the walls of the sub. As the ''Stingray's'' depth increases, the water pressure begins squeezing the hull, causing the string to sag noticeably. Howard grins at Nitro (having put up the string to demonstrate this very thing) and says...
-->'''Howard:''' Bet ya never saw anything like that on one of those big nukes.\\
'''Nitro:''' Uh, no, we didn't have clotheslines. We had those dryer things, with a window in the front.
* TheComicallySerious: Just about the entire crew of the ''Orlando''. They act completely professional and serious at all times, completely unaware of [[HilarityEnsues ensuing hilarity]] happening on the ''Stingray'', or the [[CrazyEnoughToWork unconventional tactics]] her crew is pulling off to elude them.
* CommunicationsOfficer:
** Nitro, a skilled but very eccentric electrician who manages to coerce the aging ship's radio equipment to work via various short-circuits (including several passing through [[AmusingInjuries his own body]]).
** Creator/PattonOswalt has a small role as ''Stingray'''s dedicated radio operator.
* CompositeCharacter: Nitro is apparently both the ship's electrician and radio operator (in RealLife, these are separate rates). Justified in that for this mission, the ''Stingray'' really doesn't need a full-time radio operator.
* ControlFreak: Executive Officer Martin Pascal just can't relax and go with the flow...
* CustomUniformOfSexy: Lt. Lake's uniform ends up being much more revealing after her shipmates sabotage her laundry.
-->'''Dodge''': Lt. Lake, you are ''almost'' [[DoubleEntendre out of uniform]].
* DamageControl: The ''Stingray'' ends up busting some water mains in the engine room during a risky maneuver, leading to Stepanek's BigDamnHeroes moment.
* DidntThinkThisThrough: Pascal tries to remove Dodge from command, as Dodge has intentionally disregarded Graham's orders (Dodge did so because he has higher orders from Winslow). He fails to account for two things. One, Dodge's actions have [[AFatherToHisMen earned the respect of the crew]]. Two, his own actions [[TheNeidermeyer have alienated the whole crew]]. He seems shocked and outraged when he realizes that Dodge has called him mutinous and is about to take care of the matter.
* DoubleEntendre: Take a RagtagBunchOfMisfits. Add one cute dive officer. HilarityEnsues.
--> '''Stepanek, on seeing Dodge exiting the aft torpedo room serving as Lake's quarters:''' Polishing the old torpedo, Sir?
* EmbarrassingTattoo: One of Rear Admiral Graham's complaints against Thomas is his owning one of these.
-->''' Rear Admiral Graham:''' I just don't think we should be handing over control of a billion dollar piece of equipment to a man who has [[spoiler: 'Welcome Aboard' tattooed on his penis]]!
* FreakierThanFiction: The basis of the movie - war games pitting decades-old naval hardware against modern equipment - has not only been done repeatedly in RealLife, but has often resulted in victories for the low-techs through skill and guile. The losing side has even [[MovingTheGoalposts changed the rules mid-game]] on occasion, but not in a subtle manner like Graham's manipulation of the playing area - they actually declared that ''[[TheBattleDidntCount the ships the low-techs sank were floating again]].''
* FriendlyEnemy: The crew of the ''Orlando'' are just doing their best to win the wargame, same as the crew of the ''Stingray''. It's Graham that acts as the BigBad of the film.
* GettingCrapPastTheRadar: "So what's this tattoo I've been hearing about?" "Well, it's a long story..."
* GoshDangItToHeck: Commander Knox
* HarmlessVoltage: Nitro, of course. With all the voltage he's absorbed over the years, it hardly even bothers him any more.
* HehHehYouSaidX: Dodge, when talking to the crew about a woman (Lt. Lake) being on board:
-->'''Dodge:''' All right, look, gentlemen. I know this is an unusual situation. Can't be easy for Lt. Lake here to be thrown into a jungle such as this, and I know it will make things hard on all of us...\\
'''Crew:''' [laughter]\\
'''Dodge:''' Let me re-phrase that. It's going to make things ''difficult'' on all of us as well. But if we just work together as a team, I'm sure we can handle ourselves...\\
'''Crew:''' [laughter]\\
'''Dodge:''' ''Comport'' ourselves as professionals. That is all.
* HisNameReallyIsBarkeep: Nitro's name really is Nitro -- his full name being "Michael K. Nitro" according to the filming script. He's considering "Mike" as a nickname.
* {{Homage}}: Sonar is one to Radar from ''Series/{{MASH}}'', in name if not necessarily manner.
* HotSubOnSubAction: The ''Stingray'' has to make the final stage of their run on Norfolk with the ''Orlando'' in hot pursuit.
* HyperAwareness: Sonar Technician 2nd Class E.T. "Sonar" Lovacelli can hear how much change is dropped on a nearby submarine. And a crewman eating an Oreo on another deck. And a couple of lobsters dukin' it out. This IS helped by his listening equipment, but it takes more than fancy gear to point out that someone dropped "forty-five cents. A quarter... and two dimes", after jerking as if an explosion went off in his ear after the coins hit the deck.
* IndestructibleEdible: The can of Deviled Ham mentioned in ItTastesLikeFeet.
* IndyPloy: Almost everything Lt. Cmdr. Dodge does amounts to winging it.
-->'''Dodge:''' Men, we'll need to use a tactic that is somewhat bizarre and extremely risky.\\
'''Spots:''' Actually, sir, [[LampshadeHanging I think we prefer to go with bizarre and risky]]. [[CrazyEnoughToWork It's worked for us so far]].
* InsaneAdmiral: Rear Admiral Graham. He starts off as just an asshole, but by the end of the film the lengths he goes to to try and rig the wargame and screw Dodge over have pushed him fully into Mad Brass territory.
* InsultBackfire: Graham's protests against giving Dodge a submarine over his "Welcome Aboard" tattoo only amused the other Admirals, and potentially made them more impressed with Dodge as a submariner (a naval branch that ''emphasizes'' roguish qualities). Admiral Winslow himself saw it as a positive trait for a renegade sub captain.
-->'''Winslow:''' Damn it to hell, don't go by the book! Think like a pirate! I want a man with a tattoo on his dick! Do I have the right man?\\
'''Dodge:''' (glumly) By a strange coincidence you do, sir.
* JerkassFacade: Stepanek. He makes no secret of the fact that he's out to make as much of a pain in the ass of himself as he can. [[spoiler:However, he draws the line at screwing over the other members of the crew.]] Interestingly, the fašade crumbles entirely once he has a chance to play BigDamnHero in the engine room; Yes, Stepanek, there is a place for foulmouthed badasses on submarines, it's not all cramped clockwork boredom.
-->'''Stepanek''': ''Now '''that''' was fun!''
* JoinTheArmyTheySaid: When stringing halogen lamps on the periscope as part of a ruse [[spoiler:to look like a fishing boat in rough nighttime weather]], Jackson sings an old US Army recruiting ad song.
-->'''Jackson:''' Be all that you can be!\\
'''Dodge:''' That's the ''army'' song, Jackson!
* LargeHam: Dodge
** Admiral Winslow.
* MovingTheGoalposts: Graham constantly changes the rules in order to give himself the advantage in the war games, including "I have to know where my attacker is coming from in order to catch him," as if a real enemy combatant would make it that easy. Dodge rightly ignores him; he had higher orders.
* MilitaryBrat: [[spoiler:Stepanek]], of all people. Turns out his father is [[spoiler:Vice Admiral Winslow]], and [[spoiler:Stepanek's]] been using his mother's maiden name to avoid allegations of favoritism.
* TheMountainsOfIllinois: An odd version: The Appalachians do run through Virginia, but aren't visible in any way in Norfolk, being nearly 200 miles away!
* MsFanservice: Lt. Lake, after her laundry is sabotaged.
--> '''Dodge:''' Lieutenant Lake, you are ''almost'' out of uniform.
** In-Universe, the crew views Lake as this until she proves her skill as dive officer.
* TheNeidermeyer: Rear Admiral Graham, [=LT=] Martin Pascal as well.
* NeverLiveItDown: In-universe example: Dodge's EmbarrassingTattoo, which everyone seems to know about and feel the need to mention.
* NiceJobFixingItVillain: Graham's providing a bum crew for Dodge probably would have steered him straight for another wargame victory, if only Sonar hadn't been among them. His insane talents for hearing and radar use are the most directly responsible for Dodge coming ahead in troubling situations.
* NoIndoorVoice: Pascal, most of the time. Of course, it ''is'' Rob Schneider...
* NoodleIncident: The Murmansk brushing incident. Although it's known that in RealLife there have been such incidents (which generally are the end of the responsible CO's career), the details of the one involving Dodge are unknown.
* ObfuscatingStupidity: Buckman, when confronted by Pascal regarding his [[LethalChef cooking]].
--> '''Pascal:''' Buckman! There was a ''fingernail'' in my food! You fat ass moron! Yesterday, it was a band-aid!\\
'''Buckman:''' Sorry Sir, the band-aid was holding the fingernail on.
* OfficeGolf: Early in the film, Dodge gets chewed out by his captain for playing golf off the top of their sub as it was sailing into port. He actually does rather well, hitting a long shot onto shore and getting very close to the hole.
--> '''Knox:''' Do you want me to pull in so you can putt out!?
* PermissionToSpeakFreely: Emily Lake asks for this, gets it, and then kisses the captain.
* PirateParrot: Nitro wears one [[spoiler:at Pascal's walking the plank. Oh, and it is an uncooked chicken.]]
-->'''Buckman:''' Don't let it fly away, that's supper.
* PlankGag: Dodge gets Buckman to unwittingly pull one on Stepanek, as Stepanek's comeuppance for slacking while everyone else is doing scut work.
* RadioContest: Nitro tried to connect the sub to Admiral Graham's phone call. Being Nitro, it got misdirected,
--> '''Dodge:''' Dodge here... 'Stairway to Heaven'... Music/LedZeppelin, 1971, right? Well, hey, good news, guys! We just won the Music/BillyJoel tickets and the WROK T-shirts! Nitro, you wanna get me ''Admiral Graham'', now?
* RagtagBunchOfMisfits: Dodge's crew obviously. We've got:
** A hot-tempered and uptight Executive Officer.
** A crusty old Chief Engineer who's actually a civilian contractor (because no active Naval personnel is familiar with a ''Balao''-class engine system).
** A rebellious Engineman who ''wants'' to be Court Marshaled.
** A sharp-eared Sonar Technician who could not only hear a pin drop, but identify the make and model of said pin from the sound it makes hitting the floor.
** A compulsive gambler with a well-established (and hilarious) losing streak.
** A former U.S. Naval Academy basketball player who choked on his Big Game.
** A shock-prone (and shock-addled) Electrician who can channel more voltage than a [[Franchise/{{Pokemon}} Pikachu]].
** A cigar chomping chef of questionable culinary skill and personal hygiene.
** A female Dive Officer to test the feasibility of a coed crew (giving Dodge further headaches).
** And pretty much every other insubordinate reject the Navy had available. All put together in a World War II vintage rustbucket of a submarine by a GloryHound Admiral who was actively sabotaging both the wargames and Dodge's career.
* RealSongThemeTune: "In the Navy" by the VillagePeople.
* ReasonableAuthorityFigure: Vice Admiral Winslow. He's sees the potential in Dodge and gives him higher orders that give him more flexibility than Graham would permit in the war game.
* ReassignmentBackfire: Dodge and his ''entire crew''. He also sees the importance of the war game to the Navy, while Graham simply sees it as another feather in his cap.
* RockBeatsLaser: The whole point of the film's plot is that an old diesel submarine could be a threat to US harbors - if it was crewed and commanded by people willing to play outside the rule books of more conventional submarine forces in an underwater version of guerrilla warfare. This is TruthInTelevision for modern diesel-electric subs with air-independent propulsion; not so much for a WorldWarTwo vintage submarine.
* ShipTease: Dodge and Emily. At one point Emily even expresses her admiration and gratitude to Dodge by giving him a kiss on the lips.
* ShutUpHannibal: Towards the end, Dodge calls out Admiral Graham on his flagrant cheating.
-->'''Dodge:''' Since when did the rules ever apply to ''you?''\\
'''Graham:''' You watch yourself, Dodge. You are addressing a ''superior officer''!\\
'''Dodge:''' No, merely a ''higher ranking'' one! Catch us if you can!
* SideBet:
** Money exchanged hands aboard the ''Orlando'' right after the climax of the film, between Captain Knox (CO of the ''Orlando'') and his XO.[[note]]eXecutive Officer[[/note]]
** Spots and Jackson are seen exchanging money a couple of times. Keep an eye on them whenever something exciting happens.
* SilentRunningMode: Pretty much a given in a submarine movie, and played with in multiple scenes:
** When the ''Stingray'' is trying to avoid detection by the ''Orlando'' earlier in the exercise, they're doing well in hiding until Buckman [[ToiletHumor rips a massive fart]] that the Orlando's sonar operator says almost sounds like an explosion.
** Other notable events that break silence: three loose coins hitting the deck (''Orlando'') and ''[[SoMuchForStealth accidentally hitting the ocean floor]]'' (''Stingray'').
** However, it's successfully inverted by the ''Stingray'' as well. At one point, being hunted by sonar, Dodge leads his crew in a drunken singalong. However, combined with some modifications to their profile and a howling storm, they convince the opposing sub that [[HiddenInPlainSight they're just a trawler full of drunk fishermen]].
* SpringtimeForHitler: Since he doesn't want to serve on a submarine at all (let alone one like the ''Stingray''), Stepanek tries to get himself kicked out of Cmdr. Dodge's crew, starting from the moment he first arrives. Of course, Dodge sees through it immediately.
--> '''Lt. Cmdr. Dodge:''' If I throw you off, it'll be in the middle of the Atlantic. Board the damn boat.
* TheSquadette: Emily Lake.
* StrawHypocrite: Graham doesn't like Dodge because he doesn't play by rules, or act like a proper officer. So how does Graham go about ensuring that Dodge won't receive command of a submarine? By cheating, and generally being an arrogant prick.
* StripperCopConfusion: In RealLife, at the time the movie was made women weren't allowed on US submarines -- Dodge is thus thrown by Lake's appointment as the ship's dive officer, not knowing about a (then fictional) experimental program to see if women will be allowed to serve on subs. He thought that she was hired by the crew as a present for him.
* SubmarinePirates: A U.S. Navy wargame calls for simulating an attack by terrorists working in conjunction with Submarine Pirates. Winslow's orders explicitly say "think like a pirate". The ''Stingray'' crew even plays it up [[spoiler:when making LT Pascal WalkThePlank following CAPT Dodge's decision to ignore RADM Graham's attempt to rig the wargame]], flying a "Jolly Roger" flag and dressed up in piratical clothing. [[CloudCuckooLander Nitro]] never bothers to change out of his costume or wash off the fake beard for the rest of the run, and even giving the occasional "Arr".
* TitleDrop: It's a sub movie called "Down Periscope". A title drop is a given.
* ThoseTwoGuys: Spots and R.J., the ''Stingray'''s Planesmen. The movie occasionally pauses to show them discussing whatever while at their post, usually R.J.'s basketball career and Spots' betting.
* ToiletHumor: Buckman almost ruins SilentRunningMode with a mammoth fart. More comedy as the crew must stifle any urge to shout in disgust, which stretches into an [[OverlyLongGag Overly Long]] [[IncrediblyLamePun Gag]].
-->'''Dodge''': ''Someone find Buckman and launch him out a torpedo tube!''
* WalkThePlank: What the crew of the ''Stingray'' makes [[spoiler:Pascal]] do when he pushes them too far. [[spoiler:A fishing boat is in on the joke and catches him in a strung net for laughs.]]
* WayPastTheExpirationDate:
** The food stores aboard the ''Stingray'' date, in at least one case, back to UsefulNotes/TheKoreanWar.
--->'''Pascall:''' Goddammit, Buckman, this stuff's been on the ''Stingray'' since Korea! This can expired in 1966!\\
'''Buckman:''' What's the matter, sir? It still tastes like creamed corn...\\
'''Pascal:''' Except, it's DEVILED HAM!
** Most of the crew view the ''Stingray'' as such, at least until she starts winning the wargame.
