The Beechcraft T-34 Mentor is an American propeller-driven, single-engined, military trainer aircraft derived from the Beechcraft Model 35 Bonanza .
Three initial design concepts were developed for the Model 45, including one with the Bonanza's signature V-tail , but the final design that emerged in 1948 incorporated conventional tail control surfaces for the benefit of the more conservative military (featuring a relatively large unswept vertical fin that would find its way onto the Travel Air twin-engine civil aircraft almost ten years later). The Bonanza's fuselage with four-passenger cabin was replaced with a narrower fuselage incorporating a two-seater tandem cockpit and bubble canopy , which provided greater visibility for the trainee pilot and flight instructor. Structurally, the Model 45 was much stronger than the Bonanza, being designed for +10 g and −4.5 g , while the Continental E-185 engine of 185 horsepower (hp) at takeoff (less than a third of the power of the T-6's engine) was the same as that fitted to contemporary Bonanzas.
The Model 73 Jet Mentor shared many components with the piston-engined aircraft; major visual differences were the redesigned cockpit which was moved forward in the fuselage and the air intakes for the jet engine in the wing roots , supplying air to a single 920 lbf (4.1 kN) Continental J69 jet engine in the rear fuselage.
Equipped with hardpoints for training or light attack, able to carry 1,200 lb (540 kg) of weapons on four underwing pylons. The armament could include flares, incendiary bombs, rocket or gun pods and antitank missiles. Widely exported.
Powered by a 920 lbf (4.09 kN) Continental J69-T-9 turbojet engine . The sole aircraft first flew on 18 December 1955.
Argentine Naval Aviation – 15 T-34C-1 in 1978.
Colombian Air Force – Purchased 50 T-34s in 1954, with six more acquired in 1970 and 10 in 1977. The final T-34 was retired in December 2013.
