The Yakovlev Yak-10 (Russian: Яковлев Як-10) was a Soviet light liaison aircraft designed and built by the Yakovlev design bureau in the 1940s.^[1]^[2]

Design and development

In the late 1940s the Soviet forces had a need for a light liaison aircraft that was smaller than the Antonov An-2.^[2] The company derived two four-seat aircraft with wooden wings and metal fuselages, from the earlier AIR-6.^[1] The Yak-10, a high-wing strut-braced monoplane with fixed landing gear and the Yak-13 a low-wing cantilever monoplane with a manually retractable landing gear.^[2] Both aircraft were powered by a 145 hp M-11MF radial engine.^[2] After tests in 1945, the Yak-10 was awarded a production contract for 40 aircraft, despite unimpressive performance.^[2] The company built a number of different variants but soon produced an improved design, the Yak-12, which, although of similar layout, was not a derivative of the Yak-10.^[2]

The Yak-10 only entered limited production before it was replaced by the superior Yakovlev Yak-12, and although the Yak-13 proved to be superior to the original Yak-10, production was not carried out.^[1]^[2]

Variants

Yak-10: Strut-braced high-wing monoplane powered by a Shvetsov M-11MF radial engine.^[2]
Yak-10G: Floatplane variant with twin floats.^[2]
Yak-10S: Ambulance variant with room for one stretcher.^[2]
Yak-10V: Dual control.^[1]
Yak-13: Low-wing monoplane derivative, using an almost identical fuselage and Shvetsov M-11MF engine installation, with a cantilevered wooden low wing for direct comparison with the Yak-10. One built.^[2]^[3]
