The Curtiss P-40Warhawk / Tomahawk / Kittyhawk 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 those of most Allied powers during World War II, and remained in front line service until the end of the war. By November 1944, when production of the P-40 ceased, 13,738 had been built.
The P-40 was kept in combat until the end of the war. Their last great contribution was in the defense of Denver in 1944. By now, the planes had adopted a hit and run strategy in which they would quickly dive on the enemy, shoot them up, then wheel for home just as fast.
