From 1907 to 1947, the army ran this program to train pilots for the
US Army Air Service (1918-1926),
US Army Air Corps (1926–1941), and
US Army Air Force (1941–1947). During America's involvement in
World War II (1942–1945), the rank of flight cadet was changed to that of aviation cadet, often abbreviated as A/C, and the program name was changed to the "
Aviation Cadet Training Program". From 1947, this program was run by the now separate
US Air Force. The pilot cadet program ended in 1961, but the navigator cadet program ended in 1965. ==Naval Aviator Training Program (USN)==
