Development

Entwicklung

The T-34 was the brainchild of Walter Beech, who developed it as the Beechcraft Model 45 private venture at a time when there was no defense budget for a new trainer model. Beech hoped to sell it as an economical alternative to the North American SNJ- Texan, then in use by all services of the U.S. military. Production of the T-34B for the U.S. Navy began in 1955, this version featuring a number of changes reflecting the different requirements of the two services.
After a production hiatus of almost 15 years, the T-34C Turbo-Mentor powered by a Pratt & Whitney Canada PT6A-25 turboprop engine was developed in 1973. Development proceeded at the behest of the USN, which supplied two T-34Bs for conversion. After re-engining with the PT6, the two aircraft were redesignated as YT-34Cs, the first of these flying with turboprop power for the first time on 21 September 1973. Mentor production re-started in 1975 for deliveries of T-34Cs to the USN and of the T-34C-1 armed version for export customers in 1977, this version featuring four underwing hardpoints. The last Turbo-Mentor rolled off the production line in 1990.

Operational history

Einsatzgeschichte

 

The T-34C is still used as the primary training aircraft for US Navy and Marine Corps pilots. The T-34C is currently being replaced by the T-6 Texan II. NAS Pensacola has already completed the transition to the T-6 and one of three training squadrons at Whiting Field has also transitioned. The remaining two squadrons will be transitioned in 2011.
