* 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 ''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]].)

** The Empire of the Rising Sun has the [[MeaningfulName Tsunami Tank]], the Allies have the Assault Destroyer, a destroyer that deploys treads to move on land, while the Soviet Stingray is a boat that sprouts legs and shoots electricity. The first two are actually more dangerous on land due to being able to crush infantry/vehicles, while the Stingray can only use it' Planarhockwave AoE attack in the water.

* ''TabletopGame/{{WarhammerFantasy'' has Marienburg's [[https://warhammerfantasy.fandom.com/wiki/Land_Ship land ships]].

* Warhammer Fantasy has Marienburg's https://warhammerfantasy.fandom.com/wiki/Land_Ship land ships.

* 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.

* Stage 2-1 of ''{{VideoGame/Contra}}: Shattered Soldier'' features a submarine that transforms into a giant VTOL gunship.

** 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.

* ''Fortress Saga AFK'' has your hero Louis begin with a SteamPunk bastion walking on 4 mechanized legs. It's powered by a sentient seed of the World Tree and for defense it has a massive cannon and several balconies for heroes to attack from. Later he can extend the fort's size or earn other forts such as the Sydney Opera House flying on {{Magitek}} rockets.

* ''TabletopGame/BattleTech'' has Mobile Structuers, which are literally buildings built on huge tank treads. They're impossibly rare in the setting, since the technology needed to create them was largely lost at the collapse of the Star League and even the League never considered them to be actually useful. Sure, they had the armor and firepower to take on an entire battalion of mechs and could utterly destroy [[TrampledUnderfoot anything under their tracks]] but they were horrifically slow, insanely expensive, and impossible to transport offplanet, limiting them to purely defensive roles.

Compare MixAndMatchWeapon, similar principle applied to hand-held weapons.

* Though not explicitly armed, the automated transports used by Syndrome in ''WesternAnimation/TheIncredibles'' get to Nomanisan Island by air... then go under water to dock.

** 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, a destroyer that deploys treads to move on land.

* The ''Tuatha de Danaan'' from ''Lightnovel/FullMetalPanic''. Special note should be mentioned that it primarily carries [[RealRobot mechs]] instead of aircraft. It should also be mentioned, that it's also Ballistic Missile Submarine, and can also launch mechs in this fashion as well, instead of a catapult launch.

* 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.

* The titular Objects of ''LightNovel/HeavyObject'' are all-in-one mechanized units capable of land and sea combat with enough firepower to raze small countries. They can serve as artillery or employ precision attacks to eliminate a single person; they counter infantry, smaller mechanized units, naval vessels, and aircraft. Third generation models go even further by incorporating strategic assets such as space elevators and oil refineries into the Object.

* The British series ''Series/{{UFO}}'' from 1969-70 has the ''Skydiver'', an atomic submarine with a detachable fighter jet attached to its nose. The plane is launched while the whole assembly is still underwater and makes its way to the surface by its own power. Naturally, the plane has no way to land on water but has to find an airfield on land. It is never shown how it is re-attached to the sub after a mission.

* The "[=SkyDiver=]" from ''Series/{{UFO}}'' is a submarine whose entire front end is a JATO-boosted rocket plane called Sky One. At need, the [=SkyDiver=] floods its rear ballast tanks until its bow points upward, and Sky One can launch... from ''under water''. (The word "SKYDIVER" on the side of the craft also separates. The jet is now labeled "[=SKY=] and the submarine [=DIVER=].)

[[folder: Land Battleship]]

* ''VideoGame/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, a destroyer that deploys treads to move on land.

* Many amphibious tanks and armored personnel carriers do exist in the RealLife. Unfortunately, they tend to be extremely unstable and unseaworthy, and tend to sink easily - with often fatal results.

** Remember that Maus we showed you on the Land Battleship section? It also counts as one of these. With air piped in through a snorkel, 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 Allies have two [[AwesomePersonnelCarrier Awesome Personnel Carriers]]: A hovercraft with a machine gun and torpedoes, and an IFV that starts equipped with missiles but changes its armament depending on the infantry loaded inside. And since EnemyExchangeProgram is a big part of the game, there's a different gun for ''every'' infantry unit, inculding animals and heroes.
