The Lavochkin-Gorbunov-Gudkov LaGG-3 (Лавочкин-Горбунов-Гудков ЛаГГ-3) was a Soviet fighter aircraft of World War II. It was a refinement of the earlier LaGG-1, and was one of the most modern aircraft available to the Soviet Air Force at the time of Germany's invasion in 1941. Overweight despite its wooden construction, at one stage 12 LaGG-3s were being completed daily and 6,528 had been built when factory 31 in Tbilisi switched to Yak-3 production in 1944. The LaGG-3 proved immensely unpopular with pilots. Some aircraft supplied to the front line were up to 40 km/h (25 mph) slower than they should have been and some were not airworthy. In combat, the LaGG-3's main advantage was its strong airframe. Although the laminated wood did not burn it shattered when hit by high explosive rounds.
In War Thunder LaGG-3 is a Tier 3 fighter that begins an agile fighters tree designed mostly for dogfighting, with lower speeds and a higher maneuverability than the Mig tree (which begins with I-15).
