The 99th Fighter Squadron was initially equipped with Curtiss P-40 Warhawk fighter-bomber aircraft. The 332nd Fighter Group and its 100th, 301st and 302nd Fighter Squadrons were equipped for initial combat missions with Bell P-39 Airacobras (March 1944), later with Republic P-47 Thunderbolts (June–July 1944) and finally with the aircraft with which they became most commonly associated, the North American P-51 Mustang (July 1944). When the pilots of the 332nd Fighter Group painted the tails of their P-47s red, the nickname "Red Tails" was coined. The red markings that distinguished the Tuskegee Airmen included red bands on the noses of P-51s as well as a red rudder; the P-51B and D Mustangs flew with similar color schemes, with red propeller spinners, yellow wing bands and all-red tail surfaces.
