Yak-11 airplane model. Sometimes equated with the North American T-6 trainer in terms of its widespread use, 3,859 basic Yak-11s were produced through 1956. Although production then ceased in Russia, it continued in Czechoslovakia, where it had been licensed to LET in 1953 with the designation C.11. An additional 707 of those aircraft were manufactured by LET. Many of the Yak-11's still operational in the USSR were replaced in 1958 by the Yak-11U, a tricycle-geared variation of the aircraft intended for training jet fighter pilots. Yak-11/C.11's were used not only by Warsaw Pact nations, but also by various other communist countries around the world.
While it is no longer a front-line aircraft, the Yak-11 has gained a new lease on life as a popular "warbird" thanks to its World War II Yak-3 lineage. Modified (in several instances as high-performance single-seat racers) and equipped in some cases with Pratt and Whitney engines, Yak-11s may currently be found in civilian use from Reno, Nevada to Western Australia, with specific airframes known to be in service in Belgium, the United Kingdom, France, Sweden and the Czech Republic.
