History JSC A.S. Yakovlev Design Bureau Yakovlev Yak-3
was a single-engine, single-seat World War II Soviet fighter
The Yakovlev Yak-3 (Russian: Яковлев Як-3) was a single-engine, single-seat World War II Soviet fighter. Robust and easy to maintain, it was much liked by both pilots and ground crew.[2] One of the smallest and lightest combat fighters fielded by any combatant during the war, its high power-to-weight ratio gave it excellent performance and it proved to be a formidable dogfighter
Design and development
Origins
The first of two prototypes had a slatted wing to improve handling and short-field performance while the second prototype had a wooden wing without slats in order to simplify production and save aluminium. The second prototype crashed during flight tests and was written off. Although there were plans to put the Yak-3 into production, the scarcity of aviation aluminium and the pressure of the Nazi invasion led to work on the first Yak-3 being abandoned in late 1941.
Variants
- Yak-3
- main production version
- Yak-3 (VK-107A)
- Klimov VK-107A engine with 1,230 kW (1,649 hp) and 2 × 20 mm (0.79 in) Berezin B-20 cannons with 120 rpg. After several mixed-construction prototypes, 48 all-metal production aircraft were built in 1945–1946 during and after WW2. Despite excellent performance (720 km/h (450 mph) at 5,750 m (18,860 ft)), it saw only limited squadron service with the 897th IAP. Though the problems with the VK-107 overheating were eventually mitigated, it was decided to leave the engine for the better-suited Yak-9.
- Yak-3 (VK-108)
- Yak-3 (VK-107A) modified with VK-108 engine with 1,380 kW (1,851 hp), and armed a single 23 mm (0.91 in) Nudelman-Suranov NS-23 cannon with 60 rounds of ammunition. The aircraft reached 745 km/h (463 mph) at 6,290 m (20,636 ft) in testing but suffered from significant engine overheating. Another Yak-3 with 2 × 20 mm (0.79 in) Berezin B-20 cannons was also fitted with the engine with similar results.

From 1991 to 2002 there were 21 Yakovlev Yak-3, Yak-7 and Yak-9 aircraft produced in the former Soviet Union using the original plans and dies.[13] These aircraft are powered by the American Allison V-1710 or the Pratt & Whitney R-1830 Twin Wasp engine in place of the Klimov V-12s used during the war. Several of these aircraft are airworthy, mostly based in the United States with others in Germany, Australia and New Zealand. Others have been converted to "Yak-3U" status from original Yak-11 trainers for private owners and museums.
Yakovlev Yak-3 WW2
Lighter and smaller than the Yak-9 but powered by the same engine, the Yak-3 was a forgiving, easy-to-handle aircraft loved by both novice and experienced pilots.
