An M61 Vulcan and the feed system for an F/A-18, on a stand. Each of the cannon's six barrels fires once in turn during each revolution of the barrel cluster. The multiple barrels provide both a very high rate of fire—around 100 rounds per second—and contribute to prolonged weapon life by minimizing barrel erosion and heat generation. [9]
The gun fires at 3,000 rounds per minute in short bursts of 10, 30, 60, or 100 rounds, or it can fire in continuous fire mode at a rate of 1,000 rounds per minute. [4] A linkless feed system is used. Its 20x102mm round gave it a low effective range of only 1,200 meters (3,900 ft), and its standard air-defense load of HEI-T rounds would self ...
The heart of the M167 is the M168 Cannon, a variant of the M61 Vulcan 20×102 mm rapid-fire rotary cannon. It was also effective against lightly armored ground targets. The M167 gun has now been withdrawn from service by U.S. military units, but is still used by other countries.
M197 Vulcan ©Hunini ... nicknamed “The Pig,” could spit out a sustained rate of fire at 100 rounds per minute, but this extreme rate meant the barrel had to be swapped out about every 10 ...
The M197 is essentially a lightened version of the General Electric M61 Vulcan cannon, with three barrels instead of six. Its maximum rate of fire is one quarter that of the Vulcan, largely to limit its recoil for light aircraft and helicopter use. It shares the Vulcan's M50 and PGU series 20 mm ammunition.
This rate was later changed to a fixed rate of 3,900 rpm. [3] At this speed it would take 18 seconds of sustained fire to empty the magazine. In practice, the cannon is limited to one and two-second bursts to avoid overheating and conserve ammunition; barrel life is also a factor, since the USAF has specified a minimum life of at least 20,000 ...
To develop a more reliable weapon with a higher rate of fire, General Electric designers scaled down the rotary-barrel 20 mm M61 Vulcan cannon for 7.62×51mm NATO ammunition. The resulting weapon, designated M134 and known as the "Minigun", could fire up to 6,000 rounds per minute without overheating.
In 1946, a Model 1903 Gatling gun was borrowed from a museum and set up with an electric motor drive by General Electric engineers. During test firing, the 40-year-old design briefly managed a rate of fire of 5,000 rounds per minute. In 1949 General Electric began testing the first model of its modified Gatling design, now called the Vulcan Gun ...
