Back in 1918, German arms engineer Reinhold Becker came up with a 20x80mm round that fired using primer ignition blowback in a very large machine gun to fire at 300-rounds per minute. [6] Although European designers were moving towards heavier 30 mm weapons for better hitting power, the U.S. initially concentrated on a powerful 0.60-inch (15 mm) cartridge designed for a pre-war anti-tank rifle, expecting that the cartridge's high muzzle velocity would be beneficial for improving hit ratios on high speed targets. The 20 mm caliber is a specific size of cannon or autocannon ammunition. The firing rate is selectible at 4,000 spm or 6,000 spm. From left to right:.223, .338 lapua, 50BMG, 20MM Vulcan *This is a destructive device but can be purchased by licensed dealers or with paperwork similar to buying a tranferable machinegun or suppressor and by paying a $200 transfer tax.

The round is fired by an electric priming system where an electric current from a firing lead passes through the firing pin to the primer as each round is rotated into the firing position. The Polsten was designed to be simpler and much cheaper to build than the Oerlikon without reducing effectiveness. A large shipment of 800 guns was lend-leased to Japan using the Italian submarine Comandante Cappellini , arming 388 Japanese Ki-61-I hei fighter planes. Projectiles for these guns are very similar to those for the Oerlikon 20 mm guns of World War II fame.

Lockheed Martin Armament Systems was later acquired by General Dynamics, who currently produce the M61 and its variants. [8], In 1993, General Electric sold its aerospace division, including GE Armament Systems along with the design and production tooling for the M61 and GE's other rotary cannon, to Martin Marietta. A 2000 USAF safety report noted 24 premature detonation mishaps (causing serious damage in many cases) in 12 years with the SAPHEI round, compared to only two such mishaps in the entire recorded history of the M56 round.

The Vulcan first entered aerial combat on 4 April 1965 when four North Vietnamese Air Force MiG-17s (J-5s)[20] attacked a force of 10 escorting North American F-100 Super Sabres (2 of which were assigned weather reconnaissance duties) and 48 Vulcan-armed and "bomb-laden" F-105 Thunderchiefs, shooting down two of the latter. While captured German designs (principally the Mauser MG 213C) showed the potential of the single-barrel revolver cannon, the practical rate of fire of such a design was still limited by ammunition feed and barrel wear concerns. The next generation of fighters built post-Vietnam incorporated the M61 gun internally. The South African Denel-Mechem NTW-20 is a 20mm anti-material rifle and qualifies quite admirably for the title of worlds most powerful sniper rifle 110 examples were constructed, but 109 of them were later converted into M16 MGMCs..

Japan's Mitsubishi F-1 carried one internally mounted JM61A1 Vulcan with 750 rounds. The 20 mm Hispano cannon carried by the P-38 and P-61, while formidable against propeller-driven planes, had a relatively low rate of fire in the age of jets, while other cannons were notoriously unreliable. These variants of the T45 were known as the T171 and T150 respectively and were first tested in 1952. The M61A2's lighter barrels allow a somewhat higher rate of fire, up to 6,600 rounds per minute.[12].

The M61A1 gun is mounted in the aircraft’s starboard wing root, aft of the engine inlet. [14] PGU-28/B is a "low-drag" round designed to reduce in-flight drag and deceleration, and has a slightly increased muzzle velocity of 3,450 feet per second (1,050 m/s). [21][22][23], The first confirmed Vulcan gun kill occurred on 29 June 1966 when Major Fred Tracy, flying his F-105 Thunderchief with the 421st TFS, fired 200 rounds of 20mm into a MiG-17 that had just fired a 23mm shell through one side of his cockpit and which exited out the other side.

The improved pods were self-powered and properly synchronized to the sights, while the USAF versions of the F-4 were hastily fitted with internal M61 cannon in a prominent fairing under the nose, well before the war ended (Navy Phantoms never received a cannon, continuing to rely on air-to-air missiles alone). [26], Two gun pod versions, the SUU-16/A (also designated M12 by the US Army) and improved SUU-23/A (US Army M25), were developed in the 1960s, often used on gunless versions of the F-4. M197 20mm Automatic Gun GPU-2A 20mm Gun Pod. One of Vulcan’s biggest disadvantages stems from the fact that it was designed as an airborne weapon system.
