It was a development and refinement of the Lavochkin La-5, and the last in a family of aircraft that had begun with the LaGG-1 in 1938. By 1943, the La-5 had become a mainstay of the Soviet Air Force, yet both its head designer, Semyon Lavochkin, as well as the engineers at TsAGI ("Central Aerohydrodynamics Institute") felt that it could be improved upon. The LaGG-1 had been designed at a time when it was felt necessary to conserve strategic materials such as aircraft alloys, and had a structure built almost entirely of wood. With Soviet strategists now confident that supplies of these alloys were unlikely to become a problem, Lavochkin began replacing large parts of the airframe (including the wing spars) with alloy components. Various other streamlining changes were made as well, increasing performance further. The prototype, internally designated La-120 by Lavochkin, flew in November, and was quickly put into production, entering service the following spring. The La-7 earned itself a superb combat record by the end of the war, and was flown by the top two Soviet aces of the conflict. The aircraft was also used as a testbed to explore advanced propulsion systems, including a tail-mounted liquid-fuelled rocket engine (La-7R), two under-wing pulsejets (La-7D), and two under-wing ramjets (La-7S). None of these variants proved worth pursuing, and turbojet technology quickly overtook them. Total production of the La-7 amounted to 5,753 aircraft, including a number of La-7UTI trainers. Those aircraft still in service after the end of the war were given the NATO reporting name Fin. La-07
