The Lavochkin La-7 was a Soviet single-seat single-engine monoplane fighter. It was a further development of the La-5FN.
The first prototype was built in January 1944, making its first flight on 2nd February and entering state trials on 16th February. The aircraft entered serial production in May 1944, designated La-7, and fully replaced the La-5FN on production lines by November 1944.
The La-7 was one of the best serial fighters of WWII, highly maneuverable with advanced performance characteristics and powerful armament. One on one, it was greatly superior to contemporary Axis, British and US fighters at low and medium altitudes. Other features included improved survivability and ease of control.
A total of 5,735 La-7s were built before the end of WWII.
