The Yak-9 represented further development of the successful Yakovlev Yak-7 fighter, a production version of the lightened Yak-7DI, taking full advantage of the combat experience with its predecessor. Greater availability of duralumin allowed for lighter construction which in turn permitted a number of modifications to the basic design.

Yak-9 variants carried two different wings, five different engines, six different fuel tank combinations and seven types of armament configurations. In December 1943, it became possible to install the more powerful M-107 engine on a new Yak-9U airframe: the engine mounting was new with individual faired exhaust pipes; fuselage structure and wings were made of metal and the whole aircraft was covered with a Bakelite skin .[5] Fuel capacity was increased to 400 l (106 US gal). In order to re-balance the model, the wing was repositioned four inches forward and in order to improve pitch control, the horizontal tail surfaces were slightly reduced.[6] The rear part of the canopy was lengthened and the antenna cable was moved inside it. Usual armament was a 20 mm (0.79 in) ShVAK cannon with 120 rounds firing through a hollow propeller shaft and a 12.7 mm (0.50 in) UBSmachine gun with 170 rounds.

The State trials took place from January to April 1944. They revealed a clear superiority in top speed over all other fighters in service on the Eastern front, up to 6,000 m (19,685 ft). The aircraft was simple to fly and stable. Unfortunately, the problems with the M-107A engine and moreover all the M-105 variants from which it derived, persisted:power plant overheating, oil leaks, loss of pressure in climbs, intense vibrations, burning out sparkplugs and a short engine life. Despite these defects, the Yak.9U/VK-107 was ordered into production in April 1944, with 1,134 machines produced by December 1944.[7]
