Base defense weapons systems

Koku-Jieitai Master Sgt. Hiroshi Osawa, a 2nd Air Wing Base Air Defense M-61 20 mm Vulcan cannon operator, explains the capabilities of the installation’s defense network to a group of U.S. Airmen participating in a 10-day U.S.-Japan Bilateral Career Training, at Chitose Air Base, Japan, April 12, 2017. The Vulcan is capable of firing 6,600 rounds per second and its six rotating barrels, firing at one time, permit a high rate of fire while simultaneously reducing the problem of barrel wear and heat generation. Koku-Jieitai is the traditional term for Japan Air Self Defense Force used by the Japanese. (U.S. Air Force photo by Tech. Sgt. Benjamin W. Stratton)
