Description

The ShVAK (Russian: ШВАК: Шпитальный-Владимиров Авиационный Крупнокалиберный, Shpitalnyi-Vladimirov Aviatsionnyi Krupnokalibernyi, Shpitalny-Vladimirov large-calibre for aircraft) is a 20 mm autocannon which could be mounted on aircraft, either in the wings, the fuselage or in turrets. There are 3 variants of the ShVAK, 'standard' ShVAK, 'early' ShVAK (which lacks API and FI bullets), and the ShVAKs which is a standard ShVAK synchronised and regulated to fire through a propeller arc without destroying the propeller. The synchronised ShVAK has a lower rate of fire compared to the other versions.

The turreted ShVAK has the same characteristics as the standard wing or fuselage mounted ShVAK cannons.

General info

Tell us about the tactical and technical characteristics of the cannon or machine gun.

Available ammunition

Describe the shells that are available for the weapon and their features and purpose. If it concerns autocannons or machine guns, write about different ammo belts and what is inside (which types of shells).

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Pros and cons

Pros:

  • Decent rate of fire at 720 to 800 RPM
  • Good accuracy even during prolonged bursts
  • Fragmentation-Incendiary round (FI) is good for pilot snipe and set fire
  • Tracer belt is full of FI-T aka Soviet's laser beam (keep beam on target at all time!)

Cons:

  • HEI has the worst explosive effect compared to 20 mm shells of other nations
  • Struggles against large framed and heavily armoured aircraft
  • Mediocre muzzle velocity
  • Useless at defeating armour > 20 mm
  • Most ShVAK installations have less than 200 rounds
  • Has a tendency to 'spark'

History

Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.

See also

Links to the articles on the War Thunder Wiki that you think will be useful for the reader, for example:

  • reference to the article about the variant of the cannon/machine gun;
  • references to approximate analogues by other nations and research trees.

External links

Paste links to sources and external resources, such as:

  • topic on the official game forum;
  • encyclopedia page on the weapon;
  • other literature.
