"The Tuskegee Airmen /tʌsˈkiːɡiː/ is the popular name of a group of African-American military pilots (fighter and bomber) who fought in World War II. Officially, they formed the 332nd Fighter Group and the 477th Bombardment Group of the United States Army Air Forces. The name also applies to the navigators, bombardiers, mechanics, instructors, crew chiefs, nurses, cooks and other support personnel for the pilots.

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 and later, P-51s, 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."
