The word Vulcan conjures different images for different people. If you are into Roman mythology, you think of the God of Fire. If you like the show Star Trek, Vulcan is that red planet Spock calls home. But if you are in the US military or build models of those vehicles, Vulcan is the 20mm Gatling gun that is so deadly on the battlefield.
First used in 1959, the M61 has adorned most of the US aircraft from the F-104 to today’s F-22. Its 6,000 rounds per minute can chew up enemy targets, and it has also been used by the Navy in the Phalanx CIWS system and the Army as the M163 Anti Aircraft weapon.
