 == History ==
-The Browning-Colt Mk 12 is a variant of the [[Hispano 404 (20 mm)|Hispano 404]] series of automatic cannons. Developed in the 1950s, it uses the same basic as the preceding [[M24A1 (20 mm)|M24A1]], but this new design for the United States Navy and Marine Corps uses a lighter projectile for a better rate of fire and higher muzzle velocity. The Mk 12 Mod 0, the base model came about after experience from the Korean War showed that the .50 caliber machine guns such as the [[M3 Browning (12.7 mm)|M3 Browning]] was an insufficient armament for fighter jets. The Mk 12 was used on the [[F3H-2|F3H-2 Demon]], [[F4D-1|F4D-1 Skyray]], [[A-4 (Family)|A-4 Skyhawk]], early version of the A-7 Corsair II, [[F11F-1]] Tigers and most notably on the Vought F-8 Crusader which was dubbed the "last of the gunfighters" as the United States Armed Forces planned to move away completely from auto-cannons or guns in favor of missiles. The Mk 12 did not have an illustrious career on the F-8. Despite its nickname, the Mk 12 was prone to jamming during dog-fighting maneuvers resulted in four confirmed victories with the Mk 12 on the F-8. Internationally, it was used by Argentina, Australia, Brazil, France, Kuwait, Malaysia, New Zealand, The Philippines and Portugal who were all international customers of the A-4 Skyhawk, A-7 Corsair II, and F-8 Crusader. As of 2013, it is still in service with the Skyhawks of the Brazilian Navy and Argentinean Air Force.
