Browning-Colt Mk12 Mod 0 (20 mm)
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
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.
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.
