LaGG-3-4

The prototype of the LaGG-3 was called the I-301 and was designed by Semyon A. Lavochkin, Vladimir P. Gorbunov and Mikhail I. Gudkov. The prototype was later renamed the LaGG-1 and production aircraft were called the LaGG-3. The prototype was designed and produced by the GAZ-301 factory in Khimki to the North West of Moscow. The design was approved for production in January of 1940 and in the prototype's name the I- prefix stood for istrebitel "destroyer" and the number signified the design bureau responsible (which in this case was the GAZ-301 factory). The I-301 was a single-seat, low-wing monoplane, with a semi-monocoque fuselage, and skinned with birch veneer and plywood.

The 4th Series of fighters incorporated several changes such as replacing the Berezin machine gun firing through the propeller hub with a ShVAK 20 mm with 120 rounds, deletion of the starboard cowl mounted Berezin machine gun, taller antenna mast, enlarged wing root intakes, and enlarged oil cooler intake. The 4th Series used a Klimov M-105PA engine of 890 kW (1,200 hp) During 1941 2,463 LaGG-3's were produced with 2,141 being built after their factories were relocated to the East. The counterweight at the bottom of the rudder from the 1st Series was deleted of the 4th Series.[8] In an effort to improve performance the fuel capacity was reduced from 904 lb (410 kg) to 749 lb (340 kg) and range was reduced to 438 mi (705 km).
