The Yak-7 was a Soviet single-seat fighter of the Second World War, created at Alexander Yakovlev's design bureau (OKB) on the basis of the two-seat Yak-7UTI trainer. It was produced in several versions — the Yak-7A, Yak-7B, and Yak-7DI — and saw combat from 1942. The aircraft's Nizhny Novgorod connection comes through the Sokol plant (Aircraft Plant No. 21 in Gorky), which built aircraft of the Yakovlev family during the war years.

Design and Variants

The baseline Yak-7B was powered by a Klimov M-105PF engine, a twelve-cylinder liquid-cooled unit with a takeoff power of about 890 kW (1,210 hp). Its armament consisted of a 20 mm ShVAK cannon firing through the propeller hub and a 12.7 mm UBS machine gun on top of the engine cowling; it could also carry two FAB-100 bombs.

The Yak-7DI (long-range fighter) was developed in June 1942 at Novosibirsk Aircraft Plant No. 153 named after V. P. Chkalov: it was based on the Yak-7B fuselage and a new wing with duralumin spars, which allowed four fuel tanks with a total capacity of 675 liters to be fitted. The prototype's first flight took place on July 6, 1942, and only one example was ever built. Performance of the Yak-7DI: maximum speed of 565 km/h at an altitude of 3,800 m, rate of climb of 13.88 m/s, service ceiling of 10,000 m, and range of up to 1,540 km. In August 1942, a decision was made not to put this machine into series production; after further refinement, it was launched into serial production under the designation Yak-9, which became one of the most widely produced Soviet fighters.

Combat Use

The Yak-7B was part of the arsenal of a number of outstanding Soviet fighter pilots. In particular, Amet-Khan Sultan, twice a Hero of the Soviet Union, flew the Yak-7B and the Yak-1 during the Great Patriotic War alongside other aircraft — the British Hurricane, the American Airacobra, and the Soviet La-7; in all, he flew 603 combat sorties and shot down 49 enemy aircraft, either personally or as part of a group.[1]

Series Production

Among the manufacturers of the Yak-7 was the Tushino Machine-Building Plant: in 1942–1945 it produced about three thousand combat aircraft of the Yak-7 and Yak-9 types, and also organized their repair and restoration. The single example of the Yak-7DI variant was built in Novosibirsk at Plant No. 153.

The Yak-7 and Nizhny Novgorod

The Sokol aircraft plant (during the war, Plant No. 21 in Gorky) is among the enterprises historically associated with the Yakovlev family of aircraft. The plant specialized in building fighters during the wartime period and later became one of the sites for producing the next generation of aircraft from the Yakovlev design bureau. In scale modeling, the aircraft is represented, among others, in 1:72 scale — the firm DogFighters Models released a model of the Yak-7B under catalog number 16359.
