The Yakovlev Yak-11 (NATO reporting name: "Moose", Russian: Як-11) was a trainer aircraft used by the Soviet Air Force and other Soviet-influenced air forces from 1947 until 1962.


The Yak-11 design was based in large part on the successful Yak-3 fighter; it became the Soviet Air Force's most widely used trainer aircraft and has sometimes been equated in importance with the T-6 Texan. The first prototype flew on 10 November 1945; the aircraft entered service in 1946. In total, 3,859 aircraft were produced between 1947 and 1956. From 1953, an additional 707 were licence-built in Czechoslovakia under the name LET C-11. Both Yak-11 and C-11 were used in all Warsaw Pact countries, as well as many African, Middle Eastern and Asian countries, such as Afghanistan, Albania, Algeria, Bulgaria, China, Czechoslovakia, East Germany, Egypt, Indonesia, Iraq, Hungary, Poland, North Korea, Romania, Somalia, Soviet Union, Syria, Vietnam, Yemen and Austria.

In 1958, the Yak-11 was to be replaced by the tricycle-geared Yak-11U which was intended as a trainer for jet pilots. However, the U variant was only produced in small numbers, and the Yak-11 remained in service with the VVS until 1962. A licensed copy of the Yak-11U, the LET C-11U, was also produced in Czechoslovakia in a small series.

Due to its Yak-3 lineage, the Yak-11 has recently seen widespread popularity among warbird enthusiasts. Souped-up versions of the Yak-11 can be frequently seen at air races. About 120 Yak-11s remain in airworthy condition.
