''The Final Countdown'' is a ScienceFiction film about TimeTravel that was released in 1980.

Warren Lasky (Creator/MartinSheen), an independent observer tasked with evaluating Navy procedures, is an unwelcome guest on the aircraft carrier USS ''Nimitz'', which is departing Pearl Harbor for an otherwise routine cruise. A few days into the cruise, things change when the carrier is suddenly pursued and overtaken by a mysterious electromagnetic storm. Emerging from the storm, the sailors find themselves cut off from modern civilization -- their communications don't work, their escorts have vanished, and there are no ships or planes on radar. However, they are able to pick up shortwave radio broadcasts that seem to date from WorldWarTwo.

Further investigation reveals that it's no hoax; they have somehow been transported back in time -- carrier, planes, and all -- to December 6, 1941. Captain Yelland (Creator/KirkDouglas), not being an idiot, realizes the potential of a modern nuclear carrier to turn the tide of the forthcoming Pearl Harbor battle. Wing Commander Owens (James Farentino) is not so certain, believing that it's impossible to alter the past and that any attempt would be doomed to failure.

Meanwhile, the ship's aircraft have shot down two Japanese Zero fighters that attacked a yacht (part of the Japanese forces' attempts to ensure that nobody could warn the U.S. of the impending attack), and two survivors have been rescued, one of whom turns out to be U.S. Senator Samuel Chapman (Charles Durning). Commander Owens, an amateur World War II historian, recognizes the Senator as having disappeared around the time of the Pearl Harbor attack. More crucially, had he ''not'' disappeared, he would likely have been Franklin Delano Roosevelt's running mate in the 1944 election and on his subsequent death, President of the United States.

Now they have a dilemma. Return Senator Chapman to Pearl Harbor, and not only can he alter history by becoming President, but now he's seen the ''Nimitz'' and thinks that it's part of a secret weapons program intended to trap the Japanese and make FDR a hero. Don't return him, and they've kidnapped or possibly murdered a public official of the United States. Amid the preparations for the upcoming battle, it's decided to compromise: drop the Senator and his beautiful assistant, Laurel Scott (Katharine Ross), off on a deserted island where they can ride out the war. Needless to say, Chapman isn't too happy when he finds out. Nor, it seems, is history changed so easily, as the time storm puts in one final appearance...

For the same initial premise with the sides reversed, see ''{{Zipang}}'' where a modern Japanese Aegis destroyer named the ''JDS Mirai'' gets inexplicably teleported back to the Battle of Midway.

Not to be confused with the {{Music/Europe}} song of the same name.

!!This movie contains examples of the following tropes:

* AlienSpaceBats: How the time storm comes to exist, how it works, and why it's targeting the ''Nimitz'' is left completely unexplained. The MartinCaidin {{novelization}} implies that it would be explained in a sequel, which never happened.
* ArtisticLicenseShips: mostly averted (see BackedByThePentagon, above), but the final scene substituted the ''USS Kitty Hawk'', as at the time the movie was filmed the ''Nimitz'' was part of the Atlantic fleet, which would've made sailing into Pearl Harbor somewhat difficult.
* BackedByThePentagon: The film crew got several days to shoot on the actual aircraft carrier ''Nimitz''. Actual ''Nimitz'' personnel played filmed roles, as well. For example, the F-14 that performed the Immelman from just above the water, in the dogfight with the [[ReportingName Zekes]], was flown by the Executive Officer of VF-84.
* BangBangBANG: During the hostage crisis in the ''Nimitz'' sickbay, the people seem more shaken by the bloodshed than by the effects of multiple assault rifles being fired on full auto in a small room.
* BornInTheWrongCentury: Commander Owens.
* BulletTime: The explosion of one of the Zeroes when hit by a Sidewinder missile from an F-14 is slowed down for several moments.
* ComingInHot: A fighter pilot incapacitated by the time storm makes a crash landing on the carrier.
* CoolBoat: The USS ''Nimitz'', first ship of her class, and the largest warship in the world at the time.
* CurbStompBattle: Two F-14 Tomcats versus two [=A6M=] Zeros. Heavily [[LampshadeHanging lampshaded]]. The ''Nimitz'''s air wing would have similarly shredded the Japanese attack force, but never gets a chance.
* ExplosiveInstrumentation: Control panels can be seen shorting out and throwing showers of sparks during the time travel sequences. Thankfully not many of the crew seem to be injured by these malfunctions.
* FakeNationality: The Japanese pilot taken prisoner is played by Korean actor Soon-Tek Oh.
* FighterLaunchingSequence: The film is replete with these; the very first shot of the film starts off with an F-14 taking off from (the modern-day) Pearl Harbor airfield. There are also numerous shots of Navy warplanes taking off and landing on the ''Nimitz'', including one scene where the strike group sent to attack the Japanese fleet is launched, which takes several minutes to play out.
* GenreSavvy: Captain Yelland's realization that the storm's reappearance and pursuit of his ship just as his forces are going to intercept the Japanese in the Pearl Harbor attack could only mean that it has come to take them home.
* GrandfatherParadox: Discussed and a reason not to use the Nimitz to win WWII in a matter of weeks. Besides the issue of changing the fates of millions of people and possibly preventing some of the crew's parents from meeting, the Nimitz itself is in danger. A swift end to WWII means no Manhattan Project, which in turn means Hyman Rickover never gets the chance to start the Navy Nuclear Propulsion Program, which means no nuclear powered ''USS Nimitz''.
* GunsAkimbo: A Japanese pilot does this during the hostage situation mentioned below; brandishing both an [=M1911A1=] pistol and an [=M16A1=] rifle.
* HonorBeforeReason: Yelland plans to use the ''Nimitz'' to turn the tide of Pearl Harbor because he's a U.S. Navy captain and obligated to defend his country, never mind the paradoxes it would create.
* HostageSituation: Happens when a surviving Japanese pilot overpowers a guard and grabs not one, but -''two''- guns.
* InfantImmortality: Played with; the Japanese pilot points one of his commandeered guns at Laurel's dog as it runs out of the sickbay, but the only reason he doesn't shoot it is because he's distracted by Laurel shouting at him not to.
* JerkAss: Senator Samuel S. Chapman. Being a [[StrawmanPolitical Strawman Pacifist]] also doesn't help his case.
* JustPlaneWrong: Although the US aircraft are, indeed, correct (see above, about Pentagon backing and filming aboard the actual USS ''Nimitz''), the [=A6Ms=] were really T-6 "Texan" trainers. T-6 "Texans" being [[WeaponsUnderstudies rather easier to come by]] than intact [=A6M=] Zeros.
* LetsGetDangerous: At first the F-14s just fly circles around the pair of Zeros, until they get the order to "splash the Zeros," and then they stop fooling around, leading to the CurbStompBattle mentioned above.
* MadeOfExplodium: The helicopter near the end explodes in a hilariously huge fireball because a flare gun is accidentally discharged near the doors.
** Inverted with the second Zero during the dogfight scene; the real-life [=A6M=] Zero was a notorious FragileSpeedster, yet when hit by a burst of [=20mm=] shells from the F-14's cannon [[note]] Which we might add shoots at 6 '''thousand''' rounds per minute [[/note]], it suffers little more than a knocked-out engine and crashes into the ocean largely intact. [[note]] Ironically, in real life, the Sidewinder would've been the one most likely to disable a Zero, while the M61 Cannon would've just shredded one. [[/note]]
* MassTeleportation
* MidAirRefueling: After the Tomcats get an ID pass on Sen. Chapmens yacht, an A6 Intruder modified with refueling equipment is dispatched to them to refuel them. When the aircraft meet up, there's naturally some humor about the job of the Tanker in question.
--> -'''Tomcat Pilot "Alert 1":'''(After the drouge makes contact) "Gooooood, Contact. You've got a green light, fill her up, check the oil, and clean the windshield. Over"
* OhCrap: Just look at the faces of the Japanese pilots when the F-14s scream past them, it's ''priceless''
* OurTimeTravelIsDifferent: The wormhole version.
* PistolWhip: Happens twice; first when the Japanese pilot hits a Marine in the gut with the butt of his own rifle, then later on when Senator Chapman cold-cocks a helicopter pilot with a flare pistol.
* PoorCommunicationKills: Had they told the civvies the plan, it might have avoided at least four deaths.
* RedAlert: There are two General Quarters scramble scenes; following the first time storm, and again when arming up the strike group to engage the Japanese fleet. Only the first one includes the blaring klaxon though.
* [[SuperiorFirepowerOtherNavalNukes Peace Through Superior Firepower]]: See the entry for the ''Nimitz'' class carriers.
* SemperFi: US Marines can be seen acting as security personnel onboard the ''Nimitz'', as per their traditional role aboard Navy ships.
* SetRightWhatOnceWentWrong: Does the ''Nimitz'' cause the StableTimeLoop by rescuing Senator Chapman? Commander Owens certainly thinks so.
* ShownTheirWork: Despite being a science fiction/fantasy film, this movie has one of the most accurate portrayals of aircraft carrier flight operations that you are likely to find.
* TheSlowPath: [[spoiler:Commander Owens, after being stranded on the island, takes the long way back to the present, resulting in TheReveal that he parlayed his knowledge of the future to set up the StableTimeLoop -- in part, by getting Lasky aboard for that particular voyage.]]
* StableTimeLoop: Perfectly wrapped up by TheReveal at the end, making this one of the "stabler" time loops in filmmaking.
* StockFootage: Many of the aircraft scenes. Of course, many were actually shot on the real life ''Nimitz'', making this only a partial example. During the second TimeTravel sequence, stock footage of the Pearl Harbor attack is shown.
* TemporalSickness: Passage through the time storm is extremely disorienting to everyone on the ''Nimitz''.
* ThrowItIn: The A-7 Corsair being caught by the barricade was an actual emergency landing on board the ''Nimitz'', and the film crew was allowed to capture it and put it in the film.
* TimeTravel
* TheUnfought: The Japanese task force (with the exception of the two Zeroes). Even lampshaded by a couple of US pilots.
--> '''Pilot 1:''' "Mission aborted? But we can see 'em!"
--> '''Pilot 2:''' "Ah they're gonna let the Japs do it again!"
* WhatHappenedToTheMouse:
** The pilot who makes the emergency barricade landing on the carrier after the first time storm is never seen or mentioned again, leaving the viewer to wonder what becomes of him.
** The E-2 "Hawkeye" AWACS aircraft is never seen again after they make visual contact with the Japanese fleet.
* WorldWarII
* YouAlreadyChangedThePast
* YouCantFightFate: The time storm sure is persistent. It's lampshaded by Captain Yelland, who immediately guesses that the storm has reappeared to take them home and recalls the carrier's aircraft so they won't be stranded.
* YouWouldntBelieveMeIfIToldYou: Not the precise words, but occurs twice - once when Commander Owens is trying to avoid explaining their presence in 1941 to Laurel and Sen. Chapman; and again after the ''Nimitz'' has returned to Pearl, as admirals are storming aboard to demand to know how an entire aircraft carrier got lost in the Pacific Ocean.
