The T-34A was used by the USAF for primary flight training during the 1950s. The original Mentor, a Beechcraft Model 45 derived from the famous Beechcraft Bonanza, was first flown in December 1948. The first military prototype, designated YT-34 by the USAF, made its initial flight in May 1950.

After extensive testing the USAF ordered the Mentor into production as the T-34A in early 1953. The first production T-34A was delivered to Edwards AFB in October 1953 for evaluation, and deliveries to the Air Training Command began in 1954.

The T-34A served as the standard primary trainer until the USAF introduced the Cessna T-37 jet trainer in the late 1950s. As they were replaced by the T-37, many T-34s were turned over to base Aero Clubs. In all, 450 T-34As were produced for the USAF. Three hundred fifty were built in the U.S.A. and 100 more were produced in Canada under license. In addition, two U.S. Navy versions of the Mentor were produced: the T-34B and the turboprop-powered T-34C. The Mentor also was built for the military forces of at least 10 friendly foreign nations.
