As Ystrebytel 9, representing a further development of a family of single-fighters A C. Yakovlev. When his task was to create the design plane, able to more effectively confront the German car. The basis was the Yak-7B, which 1942 g. on a range of combat capabilities are the best in the Red Army Air Force. Fundamental changes undergone wing, in which a wooden spar design replace metal (the rest of the airframe components were wooden). This not only gave a weight gain, but also has increased the volume of fuel tanks.

For further weight saving and removed one of the two 12.7 mm machine guns BS (in the armed left one more a synchronous machine gun and 20mm cannon ShVAK, firing through propeller shaft). Also, a more powerful engine M-105PF (1260 hp). To improve visibility dropped fairing and install a new lamp.
Experienced fighter sample, were designated Yak-7DI, It was submitted for testing 26 June 1942 g. The results were encouraging, aircraft surpassed the Yak-7B on flight distance, and at the same filling showed better maneuverability and climb. 5 August was completed gosis-tests carried, and Yak-7DI have adopted under the designation Yak-9. Since October 1942 g. Novosibirsk plant number 153 began production of the Yak-9 in parallel with the Yak-7B, From January 1943 g. the plane began to produce the Omsk plant number 166.

Combat use Yak-9

The first Yak-9 appeared at the front in December 1942 g. at Stalingrad. Bulk deliveries of new aircraft in the first half 1943 g. revealed quality problems. Shortcomings had to eliminate the rem-teams in the parts just before the Battle of Kursk – first battle, in which the Yak-9 used in a significant number. To her top Yak-9 was operated (along with other types of machines, mainly, Yak-1 and Yak-7) 256-I, 273-I, 303-I 323rd IAD, 1-I Hyades. At the end of July 1943 g. to the fighting on the Kursk Bulge started 11th Mixed Air Corps, has three shelves Yak-9 (4-m, 148-m and 293-m). Airplane showed very manoeuvrable in the horizontal, and in a vertical plane, easy to manage. However, the car behind the best fighters of the enemy of high-speed qualities and armament. This was because, that the Yak-9 was a much smaller motor power, Cem of Bf 109G and Fw 190A.

Qualitative superiority in arms compared with the conventional Yak-9 had Yak-9T. According to statistics, average consumption of 20 mm shells at one downed aircraft the Yak-9 was 147, and the Yak-9T 37-mm shells – only 31. One of the first Yak-9T was 133rd GIAP, who fought for them in August 1943 g. Aircraft, armed with 37 mm cannons, We tried to apply, and not without success,, even against enemy tanks and enemy craft in the Black Sea.

Operation of the Yak-9D shows, that the increased supply of fuel in most cases is not necessary and only a ballast, decreasing, in addition, survivability fighter. Therefore, in parts per console bins Yak-9D are often installed plug. But in some episodes of combat extended range has been demanded. So, a group of 12 Once 9DD in August 1944 g. perebazyrovalas in Bars (Italy), where accompanied by a transport aircraft, dostavlyavshye hruzы yuhoslavskym partisans. Yak-9DD also involved to escort American bombers B-17 and B-24 1944 g. during "Frentik" operation (shuttle bombing raids).

Yak-9B December 1944 g. They fought in the 130th IAD (3-First Byelorussian Front). High-rise Yak-9PD entered service parts of the Moscow air defense zone. In October 1944 g. It took place the combat debut of the Yak-9U – them to conduct military trials armed 163rd IAP, in force in the Baltic. The aircraft showed sharply increased military capability: two months of tests, spending 18 air Combat, regiment knocked 28 Fw 190A and 1 Bf 109G cost of losing just two of their machines.

By the end of WWII the Yak-9 was one of the main types of Soviet fighters, He remained as such in the early postwar years. As of 1 September 1946 g. Soviet fighter aircraft was 3698 Yak-9 – 31 % its composition. After the war machine of the Yak-9U and Yak-9P operated in the Soviet Air Force prior to the 1950s.

In addition to the Air Force of the Red Army and Soviet Navy Naval Aviation, Yak-9 arrived on Allied weaponry. In particular, in summer 1943 g. Yak-9 and Yak-9D was a French regiment "Normandie". In September 1944 g. Party Yak-9 gave Bulgaria, defected to the anti-Hitler coalition. Since October 1945 g. Yak-9M and Yak-9T aircraft operated by the Polish Army. They took part in the fighting in Poland, and later in Northern Germany. In the aftermath of the Yak-9 supplies, including new versions, Poland continued. Besides, Aircraft of this type entered service in China Air Force, North Korea, Hungary, Yugoslavia, Albania.
