1st Pursuit Group P-43s assigned to the Blue Force during the 1941 Carolina Maneuvers

P-43 Lancer fighters were first delivered to the United States Army Air Corps in 1940. Although initially favored, rapid fighter development of the late 1930s and early 1940s led to these fighters becoming obsolete within a year. Despite the US Army's disinterest in the P-43 Lancer design, China, which had been at war since 1937, ordered enough to keep the production line open until 1942. Some of these China-bound fighters were assigned to the American Volunteer Group, also known as the "Flying Tigers".

In the air fighters P-40 and P-43.
