Lavochkin La-7

The La-7 was a development of the La-5, which was very similar in appearance. It was fitted with a 1850hp (1380Kw) Shvetsov radial engine. Armament was increased to three ShVak 20mm cannons. The oil radiator was moved to the lower center of the fuselage. The La-7 had increase in speed of about 10-15mph over the La-5. Due to the improvements it was preferred by many Soviet Aces for its speed, maneuverability, firepower and general performance. The La-7 prototype first flew in early 1944.
The La-7 was about 44mph faster than the FW-190 (its main nemesis)

Although the La-7 was initially designed with the three-cannon arrangement, only about 368 were delivered in this configuration, compared with more than 3000 two-cannon La-7's delivered. The first operational unit to receive the new fighter was the 176th Guards Fighter Aviation Regiment in July 1944. The La-7 scored 55 victories in the 63rd Guards Fighter Aviation Regiment between September 15th and October 15th 1944. The La-7 ended service for the Soviets in 1947.
