MIM-72A CHAPARRAL SURFACE-TO-AIR MISSILE AND M163 VULCAN MINI GUN SYSTEM HISTORIC FILM 71612

Made by the Aberdeen Proving Ground, this film gives a history of the development of the MIM-72A/M48 Chaparral as well as the M163 Vulcan Air Defesne system. The M61 Vulcan is a hydraulically or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon which fires 20 mm rounds at an extremely high rate (typically 6,000 rounds per minute). The M61 and its derivatives have been the principal cannon armament of United States military fixed-wing aircraft for fifty years.
