The '''Lavochkin-Gorbunov-Gudkov LaGG-1''' ({{langx|ru|Лавочкин-Горбунов-Гудков ЛаГГ-1}}) was a [[Soviet Union|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.

==Design and development==
The LaGG-1 was designed in 1938 by [[Semyon Lavochkin]], {{ill|Vladimir P. Gorbunov|ru|Горбунов, Владимир Петрович}} and {{ill|Mikhail Gudkov|ru|Гудков, Михаил Иванович}} of [[OKB|design bureau]] [[OKB-301]] in [[Khimki]] to the north-west of Moscow. It was designed as a light-weight aircraft  around the [[Klimov M-105]] engine and built out of [[plywood|laminated wood]] to save on [[strategic material]]s. 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 new fighter proved clearly underpowered. It lacked agility and range. Furthermore, while the prototypes  were carefully handmade and finished, the mass-produced examples were comparatively crude.

The subsequent modifications undertaken by Lavochkin's [[OKB]] would result at last in the [[Lavochkin-Gorbunov-Gudkov LaGG-3|LaGG-3]].<ref name="GordonSCAoWWII">{{cite book |last1=Gordon |first1=Yefim |last2=Khazanov |first2=Dmitri|title=Soviet combat aircraft of the Second World War |publisher=Midland Pub. |isbn=1-85780-083-4 |pages=23–24}}</ref>
