The concept of a new fighter for the Soviet Air Force was pitched in 1943. While the earlier Lavochkin La-5 proved to be one of the best Soviet fighters produced up to that point, the main designer of the La-5, Semyon Lavochkin, felt that it could be improved even further. Work on a completely new fighter began in the early months of 1944. The new fighter was supposed to be an improved version of the La-5 design. The changes included the incorporation of a lighter and more durable metal air frame in place of the earlier wooden one. Other changes included the mounting of a new gun sight and propeller, as well as the strengthening of the landing gear struts and streamlining of the wings. It was to be armed with three Berezin B-20 20 mm cannons, however the delay in production meant that most new La-7s were armed with 2 x 20 mm ShVAK cannons, like its predecessor. After more tests, the new fighter was accepted into serial production in late 1944.

In certain circumstances, the speed allowed the Soviet pilots to intercept Fw 190 fighter-bombers - a feat impossible to achieve for other Soviet fighters like the Yak-3.

Soviet ace Ivan Kozhedub scored 17 kills while flying the La-7 - his last one being an [[Me262A-1a|Me 262]] jet. After the war the La-7 was replaced by the La-9 prop fighter, although many were still used by other communist states as both fighters and trainer aircraft.

Description

GarageImage Dolgushin's La-7.jpg


Dolgushin's La-7 is a gift Rank IV Soviet Fighter with a battle rating of 4.0 (AB), 4.7 (RB), and 5.0 (SB). It was introduced in Update 1.49 "Weapons of Victory". The plane is painted after the camouflage scheme of Soviet pilot Sergei F. Dolgushin in the 156th fighter aviation regiment from September 1944 onward.

The key to staying alive in the La-7 lies in deceiving the enemy. By flying at around 4.5 km altitude you present yourself as an easy target for Boom & Zoom aircraft that are flying at higher altitudes. When you spot someone diving at you, break off and evade his burst, while slowly luring him into maneuver combat - this way you will start gaining the edge while the enemy loses his speed and momentum in the turn. Another habit worth developing in the La-7 is ammo conservation - the ShVAK shoot fast and in RB it is a skill worth having - it is crucial to only take shots that you know will hit and aiming them carefully. This way you stand a bigger chance of critically damaging the enemy airplane. By following those rules you will soon find yourself researching the final Lavochkin piston fighter - the La-9.

Survivability and armour

  • 55 mm Bulletproof glass in cockpit front
  • 66 mm Bulletproof glass in cockpit rear (Can be upgraded to 75 mm with Armored glass modification)
  • 8.5 mm Steel plate behind the pilot (Can be upgraded to 10 mm with Rear armor plate modification)

Armaments

Offensive armament

Main article: ShVAK (20 mm)

Dolgushin's La-7 is armed with:

  • 2 x 20 mm ShVAK cannons, nose mounted (170 rpg = 340 total)

Suspended armament

Dolgushin's La-7 can be outfitted with:

  • Without load
  • 2 x 50 kg FAB-50 bombs (100 kg total)
  • 2 x 100 kg FAB-100 bombs (200 kg total)

Usage in the battles

Dolgushin's La-7.

Tactics

The strengths of all La-7 variants lie in very good low altitude performance - ideally, you want to engage your enemies at altitudes lower than 5 km - higher up, the power output of the engine reduces drastically, making you an easy target. Aside from the speed, the La-7 possesses very good turning capabilities - while it is not as good a turner as some British and Japanese designs, it can give many German and US aircraft a run for their money.

Pros and cons

Pros:

  • Excellent low altitude performance (< 3,000 m/9,843 ft)
  • Decent maneuverability
  • Great acceleration and climb
  • Good roll rate
  • Centre-mounted cannons
  • Decent visibility
  • Good speed in level flight
  • Pilot armor options
  • Bomb options

Cons:

  • Poor performance at high altitude (> 4,000 m/13,124 ft)
  • Poor maximum dive speed
  • Fast-firing cannons mean less fire time
  • Tends to bleed energy
  • Center-mounted cannons can be difficult to master
  • Poor stock plane as well as belts
  • Relatively poor durability- wings tend to rip at higher speeds compared to contemporaries
