Submarine

Submarines are naval warships which can fully operate while completely submerged underwater. They have a distinctive cylindrical body, and are typically propelled with a propeller or pump jet at the rear of the ship.

A diverse selection of submarines have appeared in Ace Combat games, including fictional ones such as those of the Scinfaxi class. Submarines in the series have also carried a variety of weapons, from burst missiles to AA guns to even acting as underwater aircraft carriers.

Strangereal
Submarines have been in use for decades in the Strangereal universe; it is not known how far back their deployment goes.

Dragonet and Scinfaxi classes
The first existing record of submarine development exists sometime prior to the 1980s, when an unknown Usean country developed the Dragonet-class of submarines. During the Osea/Yuktobania Cold War, the Yuktobanian Navy developed the Scinfaxi-class of submarines, which received criticism, particularly from the Osean Foreign Minister at the time, about its similarity to the Dragonet-class.

By the 1990s, two Dragonet-class submarines were fully constructed and operational: the Fensalir and the Folkvangr. Both were also developed with the capability to carry submarine-launched ballistic missiles. When the Usean Continental War broke out in the late 1990s, both submarines were captured and used by the Usean Rebel Forces to attack the Usean Allied Forces - notably, the Folkvangr attempted to fire an SLBM at Saint Ark to destroy it. However, both submarines (and the SLBM) were destroyed by Phoenix.
