The Aero L-39 Albatros is a single engine Czechoslovakian trainer that doubles as a light attack aircraft.


The L-39 was developed in the 1960s as a successor to the L-29 Delphín and first flew on 4 November 1969. After going through a number of tweaks and prototypes, production began in 1972. While used extensively by the Czech Air Force, the Albatros was also very successful in the export market, particularly with the Soviet Union. Over 3,000 were built before production ended in 1999, the majority of which are still in use. As examples were phased out of military service, the L-39 also became popular as a civilian aircraft due to its relative agility and inexpensiveness, and continues to see use as an aerobatic aircraft as well as a warbird. The Albatros was developed into the L-59 Super Albatros and L-159 Alca.
