As the first established Joint Fighter Wing, the 501st JFW is a specialist unit comprised of several of the greatest aces of the time. The unit was stationed in Britannia under the jurisdiction of the headquarters of the Western World (Headquarters: Britannia / Air Force Commander: Air Marshal Trevor Maloney) until the Liberation of Gallia after which it was disbanded. The unit has since been reformed at the order of Air Vice Marshal Adolfine Galland and is currently based in Romagna, on an island in the Adriatic Sea.
This Joint Fighter Wing is focused on the defense of Britannia and the recovery of Gallia, where their HQ is located on a strategic island in the Adriatic Sea. They have shot down a large number of Neuroi.
