Description

The Browning Colt Mk12 is a 20 mm autocannon used by the United States Navy in many naval fighters and attack aircraft from the 1950s. It was a further development of the Hispano HS 404 cannon that had been on many British, French and some American planes. Both its rate of fire and muzzle velocity are high, making it easy to shoot down high speed targets.

Vehicles equipped with this weapon

General info

The cannon is capable of firing up to 1,000 rounds per minute, the shell velocity of all types is 1020 m/s and the one second burst mass is 1,825 kg. The explosive mass of HE shells is 14 g, enough to cause a significant amount of damage to a wing with the single hit. Its accuracy it quite good, however it has two times higher shell spread than for example the M3 Browning machine gun.

Available ammunition

The Mk 12 cannon fires 20 x 110 mm USN ammunition, which was developed from the 20 x 110 mm Hispano-Suiza ammunition used by the AN/M2 and AN/M3 cannons.

The Mk 12 Mod 0 cannon can be equipped with the following belts:

  • Default: AP-T · HEI · HEI
These are comprised of Mk 106 HEI and Mk 108 AP-T rounds and are the stock belts that come with the cannon.
  • Universal: AP-T · HEI
These general-purpose belt is made up half HEI rounds and half AP-T rounds.
  • Ground targets: AP-T · AP-T · HEI · AP-I
Intended to be used against armoured ground targets, this belt is made up almost entirely of armour-piercing ammunition. It features Mk 106 HEI, Mk 107 AP-I, and Mk 108 AP-T rounds.
  • Air targets: AP-T · HEI · AP-I · HEI
This belt is arranged in much the same way as the Universal belts. However, every fourth round is now a Mk 107 AP-I round.
  • Stealth: AP-I · HEI · HEI · HEI
This belt contains the most HEI rounds of any available for the Mk 12, with Mk 106 HEI and Mk 107 AP-I rounds.
Penetration statistics
Belt Penetration @ 0° Angle of Attack (mm)

Default 33 31 27 24 19 14
Universal 33 31 27 24 19 14
Ground targets 36 33 27 24 19 14
Air targets 36 33 27 24 19 14
Stealth 36 33 27 22 17 14

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:

  • High rate-of-fire
  • Good at intercepting high speed targets due to high muzzle velocity

Cons:

  • Low amount of ammo per gun
  • Very inaccurate
  • Low ammo

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.
