The Lavochkin-Gorbunov-Gudkov LaGG-1 (Лавочкин-Горбунов-Гудков ЛаГГ-1) was a Soviet fighter aircraft of World War II. Although not very successful, it formed the basis for a series of aircraft that would eventually become some of the most formidable Soviet fighters of the war.
History
The LaGG-1 was designed in 1938 as a light-weight aircraft designed around the Klimov M-105 engine and built out of laminated wood to save on strategic materials. The first prototype flew on March 30, 1940, and once some initial difficulties had been worked out of the design, proved to be promising, if somewhat short of what its designers had hoped for. By this stage, however, the need to modernise the Soviet Air Force had been made plain by recent losses in the Winter War with Finland, and the aircraft, initially designated I-22 was ordered into production.
Some 100 aircraft were sent to evaluation squadrons, where their shortcomings quickly became obvious. The aircraft was clearly underpowered, and lacked agility and range. Furthermore, while the seven prototypes had been carefully custom-built and finished to a very high standard, the mass-produced examples were comparatively crude, and this only added to the existing weaknesses.
As reports of these problems came back to the design team, a series of modifications were undertaken that would result in the LaGG-3.[1]
