L-39 and L-139
Aero Vodochody has produced several variants of the basic L-39C, the simplest version of its second-generation jet trainer, and the L-39ZA training and light-attack aircraft. Both the L-39C and L-39ZA are powered by AI-25TL turbofan engines. The L-39V is a single-seat target tug. The L39ZO is similar to the L-39ZA, but lacks the gun pod.
The L-139 trainer/light-attack aircraft is powered by an AlliedSignal TFE731-4 turbofan. The aircraft has US avionics, including a head-up display. The L-139 was evaluated by South Africa in 1995.
L-59 and L-159
The L-59 and L-159 are developed versions of the L-39 jet trainer. The prototype L-59 was flown in September 1986, and the first production example followed in October 1989. The L-59E was flown in April 1992, leading to deliveries between January 1993 and the end of 1994.
The L-159A is a single-seat ground-attack development of the L-59, powered by the 28kN International Turbine Engines F124 turbofan in place of the L-59's Progress DV-2, and is being developed for the Czech air force. The prototype L-159T two-seat trainer flew for the first time in August 1997. A two-seat attack version, the L-159B, is also proposed.
