developed by General Dynamics M61A1 \Per minute can be fired 6,000 of the standard of M50 ammunition (optional firing rate). Wide range of equipment in the U.S. active-duty fighter, speed high reliability.
history

set a great service in World War II, the M2 .50 caliber machine gun type to North Korea face of rough skin and flesh of the MiG 23 37 mm gun with enough force appears Xinyou Yu

1947, the newly formed U.S. Air Force began to seek a new gun to replace the 12.7-mm machine gun. World War II experience shows, Germany, Japan and Italy, the Axis fighter tactical advantage in the gun position occupied by the U.S. P-51, P-47 equipped with a broad white Browning 12.7mm machine gun range is short and the power of small, and P- 38 equipment, 20 mm, \In the following the Korean War, F-86 fighter is more exposed the shortcoming of lack of gun power, significantly weaker than the MiG-15 large caliber gun.
U.S. Navy has for the small torpedo boat, gunboat development of electrically driven Gatling, a Gatling gun, the 19th century Gatling gun that emerged a new look, driven by the power of human-driven change, the basic principle remain unchanged. The high rate of fire guns, but because of restrictions on materials technology at that time, barrel wear quickly under the high rate of fire, life expectancy very short, not in use. After the metallurgical technology and new materials with the development of the modern version of the Gatling Gatling gun can finally surfaced.

1950, General Electric began as the U.S. Air Force's \Chad. J. Gatlin invented in the 19th century, Gatling Gun. In 1953, pre-production of \In the first airborne test revealed the body can not successfully discharged waste of gunpowder, spreading the problem, and for a time led to the suspension test. Later in the F-104 gun bay was designed to better address the problem after smoke hole.

the most advanced F-22 still retains the gun, red circle is that it is gun muzzle, in order to reduce the RCS value, usually is closed

After the aircraft should not prejudice the missile after, M61 became the standard U.S. fighter weapons, more F-22 specially designed lightweight \type movements is not installed M61, however, external gun pod can be). As GE's Ordnance Department have been Martin. Marietta acquisition, the M61A1 is now the official name of Lockheed - Martin M61A1.
structure

Gatlin Gatling gun barrel at the rate of fire and life on the possession of inherent advantages. While rotating in the barrel and each barrel are in different stages of launch. When the barrel to the highest point of rotation, the bore ammunition hit in fat, and then rotate to the highest point of throwing shells - loader - the highest point in the next rotation to Shiyou hit in fat - so the cycle. So the whole guns rate of fire is the sum of the six barrel rate of fire, as six 20 mm single-barrel gun and type in the shooting. Since the shooting of six barrel-sharing loop, so the next number in the same shot, \The main disadvantage of the gun (and perhaps should not call it bad) is very high firing rate, a short time to spend a lot of ammunition, in order to maintain a continuous shooting time, require large-capacity ammunition box. Single-barrel gun in Russia, the European fighter aircraft, ammunition capacity less than the U.S. fighters, one different from tactical ideas, and second, the different rate of fire gun.

original Gatlin principle cannon shells commonly used for bomb-chain , including certain models of \Although Gatlin after a long development theory is extremely reliable, but in the \Shells in the high-speed pull chain, the junction is easily deformed, bent or broken, causing machine gun jams. In addition, the elastic chain is also taking up valuable space ammunition boxes, reducing the amount of ammunition. This requires the development of new devices for bombs.
