MK-12 20mm Automatic Gun
The MK-12 gun utilized in the A-4 aircraft is a fixed mounted, gas blow back, air cooled, electrically fired, pneumatically driven weapon, with a rate of fire of 1000 rounds per minute. The MK-12 is dependent upon an outside source for
electrical and pneumatic power requirements. A MK-7 feed mechanism mates the gun to the ammunition system that has a capacity of 100-200 rounds of linked MK-100
series 20mm electrically primed ammunition.
