P-40
The Curtiss P-40 was an American single-engine, single-seat, all-metal fighter and ground attack aircraft that first flew in 1938. It was used by the air forces of 28 nations, including most Allied air forces during World War II, and remained in frontline service until the end of the war. By November 1944, when production of the P-40 ceased, 13,738 had been built.
