 After tests in 1945, the Yak-10 was awarded a production contract for 40 aircraft, despite unimpressive performance.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.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.
