-The research and development into the next aircraft armament design was designated "Project Vulcan". In June 1946, the United States Air Force and Army Ordnance gave a contract to the General Electric Company,<ref name="FAS-M61">Pike et al. 2000</ref> with the specifications for a weapon in .60 caliber (~15 mm), with between 5 to 10 barrels, weighing less than 100 lbs (~45 kg) per barrel, not exceed 80 inches (~203 cm) in length, and with a minimum RPM of 1,000. General Electric delivered the first gun, designated ''T45'', as model "A" in April 1949, which was capable of firing up to 4,000 RPM. The design was refined that by the Summer of 1950 it was capable of reaching 5,000 RPM and later up to 6,000 RPM. Ten T-45 model "A" guns were produced and extensive tests were placed onto the guns to demonstrate feasibility and reliability. By December 1950, the work on T-45 progressed into the development of model "C", of which 33 were made in three different calibers: .60 caliber, 20 mm, and 27 mm. These were tested between Army Ordnance and Air Force and the 20 mm gun version, designated ''T171'', was selected for further testing. 27 units of T171 were produced and delivered for follow-up tests and met or exceeded specifications by having six barrels, weighed about 50 lbs per barrel (total weight around 290-300 lbs), had an overall length of 72 inches, and had a rate of fire up to 6,000 RPM. The 20 mm T171 was tested within a [[F-104A|Lockheed F-104]] and was first test-fired in 1953.<ref name="F16-M61"><nowiki>F-16.net</nowiki> n.d.</ref> In 1956, the 20 mm T171 gun was standardized under the full name '''M61, 20 mm.

-The M61 was powered by either hydraulics, ram-air turbine, or a electric motor to allow compatibility with any aircraft. A multi-barrel rotary cannon, the rotation of the barrels work to strip a cartridge from the belt, fire it, then eject it within a barrel's single rotation. This rotation ensures that only one barrel is firing at a time, which helps improve the individual barrel life span. The M61 barrel life is around 15,000 rounds, while the gun overall was 100,000 rounds, with maintenance overhauls expected at around 45,000 rounds.<ref name="Gatling-Epilogue"/> The weapon's only noticeable downsides in its design was the high consumption of ammunition associated with its rate of fire and the 0.3 second of spool time required for the M61 to reach its full rate of fire to begin firing.<ref name="F16-M61"/>

-The original M61 was fed by linked 20 mm shells. However, the high rate of fire caused issues with the links that caused malfunctions during the feeding of the gun. The M61 ejection also caused issue as the large number of shell casings and links can present the risk foreign object damage to the fast-moving jet's engine. These issues were resolved with the development of a linkless feeding system, with ammo moved into a conveyer belt that feeds the gun. Some installation of this feeding system can also attach a second conveyer belt moving the spent casings back into the ammo storage area so that they do not need to be ejected. The M61 with this new feeding system was designated the [[M61A1 (20 mm)|M61A1]] and became the primary version of the Vulcan.<ref name="F16-M61"/>

-The M61 and M61A1 would initially serve as the main gun armament of most of the United States Air Force interceptors such as the F-104, [[F-105D|F-105]], and F-106. However, as the Vietnam War raged showed the value that a gun armament has on aerial combat, the M61 proliferated and aircraft not originally using the cannon were either modified to accept the M61 cannon in the fuselage or mounted externally in gun pods. Today, many of the "teen-series" of fighter jets in use by the US Air Force and Navy has the M61 or its variants as their main gun armament.<ref name="FAS-M61"/><ref name="F16-M61"/>
