->'''J.A.R.V.I.S.:''' Sir, the Mark VII is not ready for deployment.\\
'''Tony Stark:''' Then skip the spinning rims, we're on the clock.
-->-- ''Film/{{The Avengers|2012}}''

When something is brand-new, fresh off the assembly line, there is typically a period of testing and shakedown to work out all the bugs and make sure everything's working the way it should and ensure a smooth entry into service. The larger and more complex it is, the more tests it needs before its deployment. In this case, however, that important step is skipped and it's put directly into service, untried and unfinished.

Why? Because it's needed, ''right now''! Never mind that some subordinate is bound to complain, "But Sir, it's not ready yet!" Their warnings can be ignored for now, even though you might have to regret the results later.

This is common in military settings, where one side finds itself lacking in resources or up against something its current assets can't handle and so starts deploying things that really aren't ready yet. Ships that have just barely finished being built, and still have the paint drying, if that, tanks that were just designed suddenly being fielded, weaponry that has just been assembled, or at times computer systems that are compiled and implemented.

This can cause more problems, as parts of it will not be up to standards or even active at all. Field installations will then be required to get finished in days or less what might take weeks at a dedicated facility. Rushed programs will have many undetected bugs, and be unstable.

If the characters are heroes, this serves to point out how cutting edge the weapon is and may involve a MillionToOneChance. If the one giving the order is a villain, then it shows how desperate he is to defeat TheHero and his RagtagBandOfMisfits, and if they are just clueless [=NPCs=] then this is the cue for the experiment to [[GoneHorriblyWrong Go Horribly Wrong]]. Can also be used to show that ScienceIsBad. Other times, it's openly acknowledged that this is a bad idea, but [[GodzillaThreshold the situation is so dire that all the other options are even worse ideas]].

[[folder:Anime & Manga]]
* In ''Anime/MazingerZ'', Kouji decided using the [[MidSeasonUpgrade Jet Scrander]] during a battle even though it had not been tested yet in an "If I do not use it I'll die anyways" kind of situation.
* In ''Anime/NeonGenesisEvangelion'', the dummy plug system wasn't ready but Gendo Ikari thought '''it's sufficient.'''
** There's also the Evangelion units themselves. They use Unit 00 and Unit 01 in combat, even though they are a prototype and test type, respectively. Predictably, both units have numerous issues like going berserk.
* In ''Manga/NausicaaOfTheValleyOfTheWind'', the Demon Giant used by the Torumekians in the final battle was not yet ready. Consequently, it [[spoiler:fell apart after a couple of shots]].
** Movie only. In the comics it became an important character. [[spoiler:Nausicaa eventually names it Ohma; it thinks she's its mother.]] However, it quickly becomes clear that [[spoiler:Ohma ''still'' wasn't ready. It spends its time with Nausicaš slowly falling apart, eventually dying when Nausicaš has it make a HeroicSacrifice to "save" the world.]]
* Used by Char 'The Red Comet' Aznable in the Final Battle of ''Anime/MobileSuitGundam'', taking out an advanced - and unfinished - prototype mecha to match the 'White Devil' Gundam. Fortunately the only thing missing from the mecha was the LEGS which, while otherwise useful for inertial maneuvering in Zero-G, were rendered unnecessary by the thrusters in its lower torso. Consequently, while it was structurally only 80% complete, it was at full combat ability.
** The unanimated Perfect Zeong, on the other hand, would have had the legs (with the torso thrusters moved onto them). It would likely have been slower (due to the added mass) and a somewhat larger target, but more agile (better movement from the legs). Given that Char has a history of using his mobile suits' feet as weapons, the very large legs of the Perfect Zeong would have allowed for some fairly impressive kicks, too.
** An example with rather more serious consequences was the Colony Laser, Zeon's answer to the Federation's Solar Flare System, which was fired early in an attempt to prevent a secret surrender offer. It was completely wrecked as a result, denying the Principality a potentially war-winning superweapon. Apparently, it didn't occur to Gihren to wait for the Colony Laser to be completed, then ''stage a coup and break the treaty'' afterward.
** The Big Zam, activated by Dozle Zabi during the last hours of the Battle for Solomon, is another example, and one that was largely acceptable, wiping out half the Federation fleet before going down.
** In ''[[Anime/MobileSuitGundamCharsCounterattack Chars Counterattack]]'', Amuro and his team had just started the testing phase of the Nu Gundam's systems when hostilities broke out between Earth and Char's forces. Because of the urgency of the situation, they quick-wired the remaining equipment into the cockpit, slapped on whatever weapons they could find[[note]] quite literally in the case of the mech's [[AttackDrone Fin Funnels]], which were a last minute addition[[/note]], then launched without fine-tuning the instruments.
* In ''Manga/FullmetalAlchemist'', the activation of [[spoiler:doll soldiers]] qualifies. The villains are losing, so some military guy decides to use them, and scientists warns him that the tests aren't done yet, he ignores the warning, activates them and both get killed.
* ''Anime/TheSoulTaker'' (the anime): When the main villain activates Soul Anubis after its upgrades (another typical example) despite researcher's warnings, Soul Anubis ignores orders and starts to follow orders of the ''true'' BigBad.
* Team Rocket from ''Anime/{{Pokemon}}'' has on numerous occasions [[LampshadeHanging lampshaded]] the fact that many of their scheme-of-the-week contraptions haven't been properly tested.
* In the movie version of ''MagicalGirlLyricalNanoha'', Precia Testarossa was told by her superiors to have her experimental reactor ready for a full-power activation in a week. [[IgnoredExpert She tried to explain that she needed a month to complete the construction and testing, but they decided the stock price impact of getting done three weeks early was more important than making sure the thing would work]]. The reactor suffered a catastrophic meltdown upon activation... [[spoiler:resulting in the death of Alicia, Precia's daughter. Thus causing Precia's very demonstrable insanity as the BigBad of the story.]]
* ''Anime/DigimonTamers'': [[WellIntentionedExtremist Yamaki]] orders the activation of the Juggernaut program in order to wipe out all the Digimon, despite being told that it's not ready yet. This results in creating a portal that allows the Devas to enter the real world.
* A sizable portion of the problems that Sousuke has with the Arbalest in ''LightNovel/FullMetalPanic'' can be traced to the fact that it's technically still in beta, and not likely to change due to the fact that its creator committed suicide two months before the start of the series.
* In ''{{Yaiba}}'' during the Underworld Arc, Boss pit the young samurai against his best warriors, Gold and Silver, and his subordinates warns him that they're still incomplete. Of course, he doesn't listen.
* [[TheRival Reiji]] from ''Anime/YuGiOhArcV'' debuts his pendulum cards (an until-then exclusive for TheHero Yuya) when he and Yuya dueled. However, he evidently didn't test them beforehand, because he was surprised when the scales suddenly changed on him. It was at that point he realized they needed some work, but it can be assumed he rushed them out for the sole purpose of showing them to Yuya.

[[folder:Comic Books]]
* In issue 30 of ''ComicBook/ArchieComicsSonicTheHedgehog'', Robotnik and Snively are testing the Transdimensional Teleporter in order to perfect two-way travel. However, before activating the device, Snively wants to run some final diagnostics. Robotnik gets upset at the idea of "a test of a test" and activates the machine himself Ė and ends up in the Void. [[spoiler:As a side effect, the roboticized Uncle Chuck who was the intended test subject regains free will.]]

[[folder:Fan Works]]
* ''Manga/{{Evangelion 303}}'': [[http://eva303.smackjeeves.com/comics/910401/012/ In chapter 3]], Nerv wanted to use a new, experimental aircraft to perform a reconnaissance mission. [[BridgeBunnies Maya]] points out that the Jet's never been flown, even for a test flight, and they're expecting it to fly to the other side of the world, and back, at nearly 4 times the speed of sound. [[TheProfessor Ritsuko]] admits that she feels the same way, but the commander's going before the senate about the project's budget soon and needs an "ace in his pocket"; Plus, they don't know how much time they have left until SEELE's endgame. They launch.
* ''Fanfic/TheSecondTry:'' In the original timeline, Gendo tried to invoke this trope with the Dummy Plug system, and it worked (temporarily). In the altered timeline, his attempt fails because his son knew how to go about [[IncrediblyLamePun pulling the plug on it.]]
* In ''FanFic/WorldwarWarOfEquals'', as [[TheReptilians The Race]] overrun more and more of Ukraine, the Ukrainian government authorizes the unleashing of untested nerve gas on Race infantry out of sheer desperation.

* ''Film/TheAdventuresOfBuckarooBanzaiAcrossThe8thDimension''. In a FlashBack to the BackStory, Professor Hikita and Dr. Emilio Lizardo are working on an experiment to penetrate the 8th Dimension.
-->'''Professor Hikita:''' Almost ready, Dr. Lizardo. Almost.\\
'''Dr. Emilio Lizardo:''' [Prepares to start the experiment]\\
'''Hikita:''' No, not yet. No!\\
'''Dr. Lizardo:''' [Continues his preparations]\\
'''Hikita:''' No, not yet! Not yet! I'm not ready!\\
'''Dr. Lizardo:''' [Starts the experiment, leading to disaster]
* ''Film/TheLastStarfighter''
-->'''Grig:''' Remember, Death Blossom delivers only one massive volley at close range...theoretically.\\
'''Alex:''' What do you mean "theoretically"?\\
'''Grig:''' After all, D.B. has never been tested. It might overload the systems, blow up the ship!\\
'''Alex:''' What are you worried about, Grig? Theoretically, we should already be dead!
* ''Film/WildWildWest''
-->'''Jim West:''' That flying machine idea of yours. Were you acting like you knew what you were talking about, or can you build it?\\
[After the machine is prepared]\\
'''Artemus Gordon:''' Although he was considered insane by his peers, Bernoulli's theory states that the air flowing over a bird's wing is at a lower pressure than the air flowing under the wing. That's called "lift", and that is what we're now going to...attempt. Of course, it's only a theory, it's never been tested...\\
'''West:''' Stop talking.\\
'''Gordon:''' Sorry.
* ''Film/BatmanForever'':
-->'''Bruce Wayne:''' Were all the Batsuits destroyed, Alfred?\\
'''Alfred Pennyworth:''' All except the prototype with the sonar modifications you invented. But you haven't tested it yet.\\
'''Bruce:''' Tonight's a good night.
* Film/JamesBond, ''Film/TheWorldIsNotEnough'': Q's new "fishing boat" isn't ready yet when Bond hijacks it.
** ''Film/NeverSayNeverAgain''. "Not perfected yet?!"
* This seems to be a recurring problem in the ''Franchise/StarTrek'' movies:
** In ''Film/StarTrekTheMotionPicture'', Kirk rushes the completely redesigned and refit ''Enterprise'' out before she's finished due to an incoming threat to Earth. The first time they fire up the untested warp drive, the engines go into imbalance and throw the ship into a wormhole that the crew barely escape.
** ''Film/StarTrekVTheFinalFrontier'' has the ''Enterprise''-A being sent into action despite being barely operational to investigate a HostageSituation.
** ''Film/StarTrekGenerations'' begins with the ''Enterprise''-B being forced to undertake a rescue mission despite being on a shakedown cruise and not having most of her main systems installed, which was supposed to happen on Tuesday.
** Averted thus far in the reboot films. In fact, in ''Film/StarTrek'', the ''Enterprise'' is among a whole fleet responding to Nero's attack on Vulcan, and actually gets there ''last''... though [[spoiler:the delay saved the ''Enterprise'', as the ''Narada'' [[CurbStompBattle wiped out the fleet]] the moment they dropped from warp, and Nero didn't expect the ''Enterprise'' to show up afterward]].
* In the ''Film/SpiderMan1'' movie, Norman Osborne turns into the Green Goblin in the test of his stimulants after being told that it has never been tested on humans and isn't ready yet.
* Shows up in ''Film/IronMan1''. Unusually for a hero using this trope, Tony's first flight could be charitably called a miserable failure that he barely survives. It does, however uncover a previously unknown flaw in the armor's design that [[ChekhovsGun comes into play later]].
-->'''J.A.R.V.I.S.:''' Sir, there are still terabytes of calculations required before an actual flight is...\\
'''Tony Stark:''' Jarvis... sometimes you gotta run before you can walk.
** The same situation comes up in ''Film/{{The Avengers|2012}}''. Tony's old Mark VI suit is too trashed to rely on anymore, so he demands that J.A.R.V.I.S. prepare his still in testing Mark VII. The new suit arrives just in time to save his life and works perfectly during the whole battle. Of course, the Mark VII being an incremental upgrade of by then well-proven technology means there was at least theoretically less that could go wrong.
** As of ''Film/IronMan3'', Tony's become erratic from PTSD and has been rushing through prototypes without giving them the proper testing time. His successes in the film were generally earned in ''spite'' of the flawed tech instead of because of it - in fact, a number of the action scenes avert this trope because the armor is so unreliable he doesn't use it at all.
* The executioner's complaints to the warden about the unreliable electric chair in ''Series/{{Seed}}''.
--> Alright, look. We have to cancel this execution, and you know that. Okay, this chair, it cannot do the job. Okay, we have standards here. I have standards here! You remember the last time? It was like the goddamn Fourth of July in there!
* In ''JusticeLeagueDoom'', they are about to phase the entire planet to let a solar flare pass through. Though this was mainly due for being short on time.
-->'''Cyborg''': Now I just need to do a test run.\\
'''Batman''': This IS the test run. (Activates it)
* Not a device, but a chemical. In ''Film/{{Evolution}}'', the heroes are trying to figure out how to stop a hostile alien lifeform that threatens to make every Earth lifeform extinct in a matter of months due to its [[EvolutionaryLevels rapidly-evolving nature]]. The military decides to obliterate the aliens with tons of napalm. However, the heroes accidentally discover that fire only speeds up the evolution. Then the protagonist looks at a periodic chart and determines that the aliens ''must'' be susceptible to selenium poisoning by going two rows down and one to the right of nitrogen (the aliens are nitrogen-based), same as arsenic (two down and one right from carbon) is poisonous to humans. So they load up on selenium (in the form of Head & Shoulders shampoo) and take a fire truck to kill the aliens. It works. They never bothered to test their theory on any alien samples beforehand.
* {{Lampshaded|Trope}} in ''Film/{{Ghostbusters}}''.
-->'''Ray:''' You know, it just occurred to me that we really haven't had a successful test of this equipment.\\
'''Egon:''' I blame myself.\\
'''Peter:''' So do I.\\
'''Ray:''' Well, no sense in worrying about it now.\\
'''Peter:''' Why worry? [[WhatCouldPossiblyGoWrong Each of us is carrying an unlicensed nuclear accelerator on his back.]]
* In ''Film/PacificRim'', the Mark I [[HumongousMecha Jaegers]] were thrown together in 14 months. Unfortunately, this meant that certain features were skimped, including [[spoiler: radiation shielding for the pilots. As a result, Marshall Pentecost (the BigGood, a former Mk. I pilot) is SecretlyDying of radiation poisoning]].
* ''Film/AirplaneIITheSequel''. Ted Striker decides that he'll have to take the shuttle to 0.5 Worp (half the speed of light) in order to get back to the Moon before they run out of air. He's warned that the Worp drive has never been tested and that the ship will apart at that speed. It's later mentioned that no one has flown at that speed before. Of course it works anyway.
* In ''Film/GalaxyQuest'', the Thermians built the ''NSCA Protector'' from what they gathered from the Galaxy Quest TV show. The ship's flying capabilities had never been tested due to the Thermians' missing navigational skills. The ship turns out to be working just fine. Also, Jason decides to activate the Omega 13, a most powerful device that was never tested before. It works like a charm.
* ''Film/TheMartian'': The resupply probe that NASA intends to send to Watney is launched without going through its final preflight quality checks, since those take several days and Watney's on a bit of a time crunch. The rocket carrying it explodes shortly after launch.

* In the surprisingly witty children's book ''Have You Seen Who's Just Moved in Next Door to Us?'' one page has an Igor do this to his Frankenstein.
--> '''Frankenstein:''' More power, Igor!\\
'''Igor:''' But master! Think of the electric bill!
* A justified example in ''PerryRhodan'' issue #400: the installations needed to fake the destruction of Earth's entire solar system by hiding it [[JustOneSecondOutOfSync five minutes ahead in the 'relative' future]] are actually finished, but because the success of the plan hinges on no potential enemy realizing what actually happened and a sudden dis- and reappearance of the entire system would be impossible to hide they simply ''cannot'' be fully tested ahead of time. Fortunately, all the effort and prep time that went into them do in fact pay off.
* In the Literature/VorkosiganSaga book ''The Vor Game'', the brand-new flagship of the Barrayaran fleet, ''Prince Xav'', launches for battle with construction crews still aboard putting in the finishing touches. [[spoiler: Fortunately, getting there with big enough guns mostly ends the actual battle]]
* In ''Literature/HonorHarrington'', during the Second Havenite War, many [[TheKingdom Manticoran]] ships were deployed without completing full builders' trials, and sometimes with shipyard reps still aboard.
* In the ''Star Trek TNG'' novel "Rogue Saucer", the ''Enterprise'''s saucer section has been undergoing repairs when it's called into action, without time to do the proper tests. Unusually for the ''Star Trek'' setting, rushing into service without testing does cause difficulties later: when the time comes to dock with the stardrive section (which is in hot pursuit of the villains' ship), one of the repairs turns out to be faulty. They have to stop and make further repairs, giving the bad guys a head start.
* In ''Literature/CommandAndConquerTiberiumWars'', in the midst of fighting the Scrin, GDI scientists are working on developing more effective weapons, which even includes foregoing their aversion to [[GreenRocks Tiberium]]-based weaponry. They hastily develop a Tiberium-based beam weapon that appears to be effective but, during a pitched battle, a major flaw is discovered. There is a small chance that the weapon's Tiberium shielding may fail, resulting in the soldier being exposed. Despite this, GDI command orders the soldiers to keep using it, as there's nothing better.

[[folder:Live Action TV]]
* ''Series/StarTrekTheOriginalSeries'' episode "The Naked Time". The Enterprise is minutes away from burning up in the planet's atmosphere.
-->'''Scott:''' Captain, you can't mix matter and antimatter cold. We'd go up in the biggest explosion since...\\
'''Kirk:''' We can balance our engines into a controlled implosion.\\
'''Scott:''' That's only a theory. It's never been done.\\
'''Kirk:''' We've got to risk a full-power start. The engines were shut off. No time to regenerate them. [snip] We've got to risk implosion. It's our only chance.\\
'''Spock:''' It's never been done.\\
'''Kirk:''' Don't tell me that again, Science Officer! It's a theory. It's possible. We may go up into the biggest ball of fire since the last sun in these parts exploded, but we've got to take that one in 10,000 chance!
** Scotty is, in fact, the patron saint of this trope. All other Starfleet engineers aspire to live up to his example.
** Just about every prototype and jury-rigged piece of machinery, in fact. So much so that it's probably covered at Starfleet Academy.
** ''Series/StarTrekVoyager'': The ''Delta Flyer'' was built in a matter of days, but since they were in a race with some aliens to get one of their probes back, they had to launch before it was ready. It was still suffering from a microfracture problem that led to a hull breach in the atmosphere of a gas giant.
* ''Series/StargateSG1'':
** The Asgard ship ''O'Neill'' was barely out of drydock before it was used to draw a Replicator fleet away from the Asgard homeworld and blown up.
** The Russian BC-304, ''Korolev'', was rushed into service to help fight the Ori invasion at the Supergate, and was destroyed in the battle.
*** The same may have happened with the Chinese ''Sun Tzu'' in the ''Series/StargateAtlantis'' GrandFinale, as it received ''far'' worse damage than the American ''Apollo'' and might end up being scuttled.
* ''Series/StargateAtlantis'': In an AlternateTimeline the newest BC-304, the ''Phoenix'', was sent to the Pegasus Galaxy to help curb Michael's forces. It was so new that more than half it's systems were not operable yet and Carter and McKay had to finish the work themselves. While it's not stated, it's implied that the ''Phoenix'' didn't even have working railguns and only used the Asgard plasma beams. While they're devastating, they're useless against small, maneuverable targets (which the Wraith tend to spam).

[[folder: Sports]]
* In 1996, Formula 3000 manufacturer Lola began work on a UsefulNotes/FormulaOne entry, with an eye to joining the sport in 1998. However, title sponsor MasterCard demanded the team enter in 1997 instead, leaving them barely enough time to design and build the car and no time at all to test it. When they got to the first race, the car was abysmally slow, both drivers failed to qualify, [[EpicFail and the team promptly collapsed]].

[[folder: Tabletop Games]]
* Happens occasionally in ''TabletopGame/{{Warhammer 40000}}''.
** The Tau have sent several of their MiniMecha battlesuits into service without proper testing (sometimes with unintended side-effects) and one of their experimental rifles had the nasty tendency to kill its own wielder via neural feedback.
** The Imperium did this in Armageddon. There were plenty of reports of Leman Russ battletanks being piloted mere seconds after their construction (without even a single coat of primer) and joining the battle raging just outside the factory doors.
** The Orks do this all the time, but mostly because "testing" and "safety" aren't really in their vocabulary.

[[folder: Video Games]]
* The Trace machine from ''VideoGame/AnotherCode'', which was only just finished mere days before the start of the game. A little more justifiable than most, given the need for a human test subject and Richard was the only one there when it was finished. [[spoiler:The earlier model in the second game averts this, as it was tested and worked perfectly.]]
* Said to Elder Lyons about Liberty Prime near the end of ''VideoGame/{{Fallout 3}}''.
* In ''VideoGame/ShadowTheHedgehog'', the commander calls for a GiantMecha called the Diablon (which he himself will pilot). The subordinate responds in this way.
* ''VideoGame/SonicUnleashed'': Dark Gaia, of course, who had yet to reach maturity within the planet's core. Ergo, it was still incomplete at the time of its awakening. Ergo, it was unable to sustain its own weight upon its release. [[OverlyLongGag Ergo]], it scattered across the world.
* ''Videogame/CrashBandicoot1996'': When Dr. Neo Cortex and N. Brio are trying to brainwash the newly created titular hero.
-->'''Dr. Cortex:''' Quickly! Into the Vortex!\\
'''N. Brio:''' But Doctor Cortex, the Vortex is not ready! We have no idea what it could do!
* ''VideoGame/CommandAndConquerRedAlert3'': In the bowels of the besieged Kremlin, Colonel Cherdenko has an exchange with Dr. Zelinsky about his [[TimeTravel Time Machine]] that follows this trope.
* Done in ''VideoGame/{{Croc}} 2'', where Baron Dante tells his minions to send out a giant t-rex robot. Naturally, he doesn't listen.
* In the Hikage Street level of ''[[VideoGame/JetSetRadio Jet Set Radio Future]]'', [[AxCrazy Hi]][[TheCaptain ya]][[DiscOneFinalBoss shi]] yells at a subordinate to send in "the experimental weapon!" He's met with this reaction, and it's implied that he has a pretty violent tantrum. The subordinate reluctantly obeys. Oddly enough for a SecretWeapon, this is considerably early in the game, and he returns in a later chapter with an improved version.
* In ''VideoGame/ProfessorLaytonAndTheUnwoundFuture'', [[spoiler:Bill Hawks]] pushed his [[spoiler:time machine]] into testing before it was ready because corporations were offering him lots of money. The resulting disaster [[spoiler:killed Claire and dozens of other people]], and resulted in [[spoiler:Dmitri seeking a way to bring Claire back, while Clive, a young boy orphaned by the disaster, grew up to want revenge on both of them]].
** [[spoiler:Also notable in that Bill Hawkes not only got away scott free for this, but [[KarmaHoudini actually got the money from the corporation and used that money to eventually become Prime Minister]].]]
* One of the Web Of Intrigue nodes in ''VideoGame/{{Prototype}}'' recalls General Randall insisting that the {{Super Soldier}}s be fielded immediately despite a scientist's reservations on the decision. Hilariously, he tells the ''scientist'' he's "not paid to think." The Super Soldiers work fine, and in fact are superior to the Hunters in several ways.
* In the introduction cutscene to ''VideoGame/DonkeyKong64'''s final level, K. Rool realizes that the Kongs are attacking, and that he needs to arm his DoomsdayDevice NOW. As the Blast-o-Matic powers up, a minion pleadingly tries to tell him it's not finished and could blow them all up, but K. Rool is too wound up to listen to reason.
* At one point in ''VideoGame/BatmanArkhamCity'', you call up Alfred and tell him to drop off a grapnel upgrade that will allow you to travel farther and faster. Alfred warns Bruce that Lucius Fox hasn't declared it ready for field deployment yet, but Batman insists that he can handle it (justifying the difficult PassThroughTheRings missions that unlock it). As far as the gameplay is concerned, the upgrade works fine.
** The Extreme Environment (XE) Batsuit in ''VideoGame/BatmanArkhamOrigins''' "Cold, Cold Heart" DLC story is a prototype, thermal system-equipped Batsuit still in development, but Batman is able to put it on and use it just fine, and he has to since otherwise he doesn't have a hope in hell of beating or even surviving Mr. Freeze without it. The trope is played with here, as it's ''Batman'' who argues against using it as its still unfinished and untested, Alfred insisting on its usage, and that Batman has Alfred finish it up and run some tests before deploying it.
* Applies to [[LostSuperweapon The Crucible]] in VideoGame/MassEffect3, since the galaxy knows they cannot beat [[EldritchAbomination The Reapers]] in a conventional fight. [[PlayerCharacter Commander Shepard's]] War Assets determine the level of completion by the endgame. Even at 100% they have no idea what it will even do.
* ''VideoGame/StarcraftIIHeartOfTheSwarm'': during the attack on Korhal, Mengsk orders special new nuclear weapons used against a group of Ultralisks attacking the city. The nukes produce a unique type of radiation, which the Zerg are able to absorb in order to mutate all of their Ultralisks into ''[[AutoRevive Torrasques]]''. Mengsk's aide does warn him that using the nukes wasn't a good idea...
* In ''VideoGame/GhostbustersTheVideoGame'', ''your job'' is to test the prototype equipment. Peter and Winston [[LampshadeHanging hang a lampshade]] on it with this exchange:
--> '''Peter''': And what makes you think it's going to stop guys like us?
--> '''Winston''': Yeah, man, what are we? The FDA?
* ''VideoGame/TIEFighter'' has the Corvette ''Vorknkx'', which houses an experimental cloaking device that is extremely unstable if used in conjunction with a hyperspace engine. [[spoiler:Zaarin does anyways. It explodes.]]
* ''VideoGame/KerbalSpaceProgram'' lets you do this to ''yourself''. Kerbal astronauts will happily crew your creations, the personnel in the VAB and SPH are a bunch of yes-men to whatever the hell craft you're assembling, and while there ''is'' a checklist in the assembly buildings to make sure you have the various pieces needed for certain tasks, you're under no obligation to even obey ''that''. Literally nothing stops you from taking Kerbals across the Kerbol system and back in a completely untested craft except for how well the craft was designed and piloted. Fan lore paints the whole Kerbal species as this: they're so excited about going to space, that everything resembling caution or design testing and review goes completely out the window.
* In ''VideoGame/XComEnemyUnknown'', your base includes a laboratory full of scientists feverishly reverse-engineering captured alien tech and sending your soldiers into the field with hastily cobbled-together prototypes based on principles that aren't fully understood and concepts that were entirely unknown mere days before. [[GameplayAndStorySegregation They all work perfectly.]]

[[folder: Webcomics]]
* Shows up in ''Webcomic/TheAdventuresOfDrMcNinja''. The leader of Raptor Force insists that [[spoiler:a horrorsaurus]] be sent to the battlefield, over the scientists' protests that it's too young.
** And in "Army of One", the doctor asks how he could say no to a machine that [[spoiler:clones him hundreds of times so he can learn many lifetimes of study in a few years, and then merge back into one]], and is unfazed when told that the machine is completely untested.

[[folder:Western Animation]]
* ''WesternAnimation/JonnyQuest'' TOS episode "The Robot Spy": The title opponent is escaping.
-->'''Race Bannon:''' What if they can't stop it, Doctor?\\
'''Benton Quest:''' Then we'll use my Parapower Ray Gun.\\
'''Race:''' But you don't even know if it works! You haven't tested it yet!\\
'''Benton:''' We don't have a choice. We have to test it now. We've got to stop the robot!\\
** As it turns out, the gun is CoolButInefficient; it stops the robot, but not the way it was supposed to.
* Used in ''WesternAnimation/{{Superjail}}'' when the Twins' creation Combaticaus starts dominating The Warden's Fight City arena. The Warden call on The Doctor to release Prototype 7 which the Doctor exclaims its not ready. Subverted however in that it turns out to be more then a match for Combatitcus and saves the Superjail staff when Fight City starts to crumble.
* ''WesternAnimation/{{Arthur}}'' plays with this in the episode, "Get Smart", in which Mr. Ratburn's class is equipped with a new computerized whiteboard called HUGO (a ShoutOut to HAL-9000 from ''2001ASpaceOdyssey'') - HUGO claims Ratburn is incorrect in one of his lessons, despite Ratburn insist he's correct. Brain is suspicious of HUGO's true accuracy, and his suspicions are confirmed, not only by doing his own research, but also thanks, in part, to [[ImagineSpot a vision he has]] where the laboratory HUGO was developed turned up its accuracy level was only 98%, which the developers dismiss, figuring 2% inaccuracy isn't going to make a difference.
* Deconstructed a number of times on ''WesternAnimation/{{Exosquad}}'':
** The GRAF Shield (a device which essentially weaponizes gravity and crushes its targets like tin cans) is used for the first time without being tested by the Neos in an attempt to surprise the Exofleet. It seems to work at first, but then starts destroying the Neo ships. It's assumed that the device doesn't work, but in truth it was sabotaged in such a way so that it would look that way.
** Later the humans of the Exofleet are reduced to hiding from the Neos in the middle planets of the solar system, having been driven out of the the core planets of Earth, Mars, and Venus. They frantically try to construct a GRAF Shield of their own around their main base so they'll have one safe spot in the solar system. As a Neo fleet closes in on them, they frantically use their untested weapon... and it works just long enough to scare the Neos off before shorting out and needing to be rebuilt. What follows is several tense episodes where the only thing keeping the Neos from crushing the remains of the Exofleet is their mistaken belief that the GRAF Shield is operational, and the humans don't dare to do anything that would clue the Neos in.
** Near the very end of the series as the Exofleet and SpacePirates begin attempting to reconquer Earth, Phaeton orders the release of all [[PeopleJars Neo Lords currently in production]] to bolster the defense of Earth, but the incompletely bred Neo Lords dissolve into mush almost instantly and cannot be deployed to combat, effectively wasting all the effort that went into the project.
* In ''WesternAnimation/DangerMouse'', Colonel K sends the titular character a vitamin pill prototype that he instructs to have tested and to not give it to himself or Penfold. Naturally, Penfold thinks it's a piece of candy and swallows it anyway. It turns him into a [[RhymesOnADime rhyming superhero]], the Blue Flash.
* On ''WesternAnimation/DuckTales'', Fenton launches a successful ad campaign for a product called "Pep", but has neglected to actually ''make'' a product to sell. Going to Gyro Gearloose, he chooses a prototype gum that allows the chewer to float, despite Gyro's warnings that it's untested. Unfortunately, the gum works too well, and now all of Duckburg's citizens can't get back down.
* In ''WesternAnimation/KimPossibleMovieSoTheDrama So the Drama'', Kim puts on the battlesuit for the first time to rescue Eric from Dr. Drakken, despite Wade's protests that the suit is "still just experimental". The suit works just fine, but [[spoiler:Kim is caught off guard when Eric reveals himself to be one of Drakken's synthodrones]].

* During UsefulNotes/TheAmericanCivilWar the ''Monitor'' was rushed into production by the Union in order to combat the ''Virginia'', the first iron-sided ship fielded by the Confederates.
* For the July 1943 ''Operation Citadel'' of UsefulNotes/WorldWarII, known in German and English as 'the Battle of Kursk', Hitler delayed the offensive so a hundred 'Elefant' assault guns, a hundred Panzerkampfwagen-VI 'Tiger' heavy tanks and another hundred Panzerkampfwagen-V 'Panther' medium tanks could be deployed alongside the 1.5k regular tanks. As it happened, a good half of the new German vehicles were knocked out by non-combat factors - many suffered simple mechanical breakdowns or were immobilised by Soviet minefields. The process of fixing the damage was exacerbated by the engineers' lack of familiarity with the new machines. In combat their impenetrable frontal armour also failed to keep them from being disabled by Soviet anti-tank infantry, who used artillery fire to separate the German infantry from the panzers and then got up close to blow the panzers' tracks off with handheld weaponry. This was facilitated by the lack of machine guns on many of the new German vehicles, many of which had yet to be equipped with them on account of the speed of their production and shipment to the front. To add insult to injury, prior combat-testing of the vehicles actually resulted in some of them being destroyed outright. This is because the Soviets had captured the first 'Tiger' prototype used in combat (at Leningrad in the winter campaign of 1942-3), designed a new model of anti-tank gun capable of penetrating its 'impenetrable' frontal armour, and deployed the first hundred of these new guns to the ''Kursk'' sector.
* HMS ''Prince Of Wales'' was immediately dispatched in pursuit of ''Bismarck'' with shipyard workers still aboard even though she hadn't been given a proper shake-down period. She still managed to give a good account of herself during the battle of Denmark Strait despite constant problems with turrets of a new, untested (and quite troublesome, as it turned out) design that reduced her firepower to to just two guns for much of the battle. Despite her difficulties she scored the hit that forced the Bismarck to turn back. It's especially notable because the Germans elected not to include ''Tirpitz'' in their sortie because ''Tirpitz'' was still in her shakedown period.
