The Curtiss P-40 first flew in 1938, being a modification of the Curtiss P-36 Hawk. It was the third most produced American Fighter after the P-47 and the P-51. The Warhawk flew with most Allied Air Forces in every theater of operations from the Aleutian Islands to North Africa and the South Pacific. Claire Chennault’s famed Flying Tigers, the 1st American Volunteer Group(AVG), was a unit of the Chinese Air Force. Although ready for combat before the attack on Pearl Harbor, the Tigers didn’t see combat until December 20, 1941. The Flying Tiger’s shark mouth fighter remains among the most recognizable of any individual aircraft of WWII. During the Japanese attack on Pearl Harbor, December 7, 1941, P-40’s from Haleiwa Field engaged the attacking Japanese planes and managed to shoot down several of them. This P-40E, is of the 23rd Fighter Group(CBI) Theater, integrated from the AVG in 1942.
