The strategic location of the United States resulted in the development of two major branches of military aviation — army and naval aviation. Specifications of primary importance were a long operating range, strength and durability, and easy maintenance. The U.S. focused on building high-speed, high-altitude fighters with the ability to carry strike weapons to provide air support to ground and naval forces, and protect friendly high-altitude bombers.
Fighters were mostly designed for vertical mid- to high-altitude combat. The P-51 Mustang and F4U Corsair are perfect representations of the U.S. fighters. Jet-powered aircraft were also employed as fighters to achieve air superiority in mid- and high-altitude combat.
Heavy fighters were designed as strategic aircraft to be rapidly deployed over long distances and perform a wide range of missions. Priority was given to maximum speed and long flight range.
American fighters are split into two lines: a carrier line (more maneuverable and climb) and an air force line (good allround speed and climb)
American heavy fighters are the fastest and more manoeuvrable of their tier but have less firepower and HP pools of their german and british counterparts.
