The 444th Air Base is an Osean Air Defense Force base. It is located in south-east Usea in Zapland.


The base covers two areas: an island airbase and a mainland installation. A prison is included as part of the base.

The mainland installation is used as a decoy base. A large variety of aircraft is stored there, including F-16C Fighting Falcons, F/A-18F Super Hornets, C-17A Globemaster IIIs and B-52H Stratofortresses.

A small naval dock is situated on the edge of the island airbase, housing three ships of the Osean Maritime Defense Force.,


The base was originally a prison for convicted Osean military prisoners. Avril Mead was also sent here despite being a civilian.

On the outset of the Lighthouse War, Osea devised to use the base as a lure. Fake targets including planes and even runways were set up for Erusean forces to bomb. It was Osea's intention to build up their forces elsewhere while this base served to distract Erusea.

Spare Squadron was later formed from pilots who were serving sentences at the base and the 444th Air Base served as their base of operations until Operation Full House where majority of Spare Squadron and 444th Air Base personnel would be stationed in Tyler Island while Trigger and Count assigned to protect base commander D. McKinsey's transport on route to Bulgurdarest.



  • The number 4 is considered an unlucky number in Japan; it can be pronounced "shi", which shares the same pronunciation for death (死).
  • The 444th Air Base may be based on the former Johnston Island Air Force Base in Johnston Atoll.
  • The use of inflatable dummies by the dummy air base is a reference to Operation: Fortitude, a World War II deception operation intended to convince the Germans that the D-Day landings would come by way of the Pas de Calais instead of Normandy.
