Description

The Aero L-29 Delfin (NATO reporting name: Maya) is widely regarded as the most produced military training aircraft in the world. It served as the standard training aircraft for the Warsaw Pact countries and many other states with varying degrees of association with the Soviet Union. It is estimated that around 3,500 L-29s were built, with 2,000 of them being allocated to the Soviet Air Forces.

The origins of the L-29 date back to the late 1950s when the Czechoslovakian aerospace manufacturer Aero Vodochody began developing a new jet trainer to replace the aging piston-engine trainers in service at the time.

The L-29 Delfin was a jet trainer aircraft characterized by its simple design and construction. It featured a mid-wing configuration with straight wings and a T-tail arrangement. The landing gear was strengthened to withstand high stresses and to operate from unprepared or minimally-prepared runways. Despite being relatively underpowered with its Motorlet M-701 turbojet engine, the L-29 exhibited interesting flight characteristics and was a pleasure to fly. The aircraft had manual flight controls, while hydraulic systems were utilized for operating the flaps and air brakes. It had tandem seating for the trainee pilot and instructor, each with separate canopies. Both occupants were equipped with interconnected ejection seats that would fire in synchronization to avoid mid-air collisions.

The aircraft served in various training roles, including basic, intermediate, and weapons training. It could be equipped with pods, bombs, or rockets for ground attack missions, carrying up to 200 kg of military payload, and proved effective in this role. During the 1973 Yom Kippur War, Egyptian L-29s were employed in ground attack missions against Israeli land forces, and the type was used during the late 1960s Nigerian Civil War.

Production of the L-29 continued from 1963 to 1974 before gradually being replaced by the L-39 Albatros in many air forces. However, it continued to serve alongside the L-39 for some time. During the First Nagorno-Karabakh War, Azerbaijani forces extensively utilized the L-29 for ground attack missions but suffered significant losses to Armenian air defenses. In 2016, it appeared that some examples were still in service in Angola and Georgia.
