Demonstration of the 30-mm GAU-8 Avenger (A-10 Thunderbolt II Main Gun) and the 20mm M61 Vulcan mounted on Phalanx CIWS, C-RAM during test fire / training. 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 was originally produced by General Electric. After several mergers and acquisitions, it is currently produced by Gener

In 1949, General Electric carried out the first tests of the T-45 prototype — the six-barrel Gatling system that would evolve into the legendary M61 Vulcan. That early design already reached a rate of fire of about 2,500 rounds per minute, an impressive leap for post-war aviation engineering. By 1950, engineers pushed the firing rate to around 4,000 rpm, and in 1952 the improved 20 mm version, designated T-171, entered official testing. The weapon proved so reliable and powerful that it was stan
