context_page_description: The Yakovlev Yak-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. 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.
  Marcel Albert, a World War II French ace who flew the Yak-3 in the USSR with the Normandie-Niémen Group, considered it a superior aircraft to the P-51D Mustang and Supermarine Spitfire. It was also flown by Polish Air Forces and the Yugoslav Air Force, after the war.

  main production version
  Yak-3 (VK-107A)
  Klimov VK-107A engine with 1,230 kW (1,649 hp) and 2 × 20 mm 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/447 mph at 5,750 m/18,865 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 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 Berezin B-20 cannons was also fitted with the engine with similar results.
  Yak-3K
  tank destroyer with a 45 mm Nudelman-Suranov NS-45 cannon, only a few built because Yak-9K was a better match for the weapon
  Yak-3P
  Production started after war armed with 3 × 20 mm Berezin B-20 cannon with 120 rounds for the middle cannon and 130 rpg for the side weapons. A total of 596 being built, none of them took part in combat. The three-cannon armament with full ammunition load was actually 11 kg (24 lb) lighter than that of a standard Yak-3, and the one-second burst mass of 3.52 kg (7.74 lb) was greater than that of most contemporary fighters.
  Yak-3PD
  high-altitude interceptor with Klimov VK-105PD engine and a single 23 mm Nudelman-Suranov NS-23 cannon with 60 rounds of ammunition, reached 13,300 m (43,635 ft) in testing but did not enter production due to unreliability of the engine.
  Yak-3RD (Yak-3D)
  experimental aircraft with an auxiliary Glushko RD-1 liquid-fuel rocket engine with 2.9 kN (650 lbf) of thrust in the modified tail, armed with a single 23 mm Nudelman-Suranov NS-23 cannon with 60 rounds of ammunition. On 11 May 1945, the aircraft reached 782 km/h (486 mph) at 7,800 m (25,591 ft). During the 16 August test flight, the aircraft crashed for unknown reasons, killing the test pilot V.L. Rastorguev. Like all mixed powerplant aircraft of the time, the project was abandoned in favor of turbojet engines.
  Yak-3T
  tank destroyer version armed with 1 × 37 mm Nudelman N-37 cannon with 25 rounds and 2 × 20 mm Berezin B-20S cannons with 100 rpg. Cockpit was moved 0.4 m (1 ft 4 in) back to compensate for the heavier nose. Engine modifications required to accept the weapons resulted in serious overheating problems which were never fixed and the aircraft did not advance beyond the prototype stage.
  Yak-3T-57
  single Yak-3T with a 57 mm OKB-16-57 cannon
  Yak-3TK
  powered by a VK-107A engine, and fitted with an exhaust turbocharger.
  Yak-3U
  Yak-3 fitted with Shvetsov ASh-82FN radial engine with 1,380 kW (1,851 hp) in an attempt to increase performance while avoiding the overheating problems of VK-107 and VK-108. Wingspan increased by 20 cm (8 in), wings moved 22 cm (9 in) forward, cockpit raised by 8 cm (3 in). Armament of 2 × 20 mm Berezin B-20 cannons with 120 rpg. The prototype reached 682 km/h (424 mph) at 6,000 m (19,685 ft) and while successful did not enter production because it was completed after the war.
  Yak-3UTI
  two-seat conversion trainer based on Yak-3U powered by Shvetsov ASh-21 radial piston engine. The aircraft became the prototype for the Yak-11.
