-Before World War II, the aircraft of different nations were armed with either rifle-calibre machine guns or heavy machine guns with rifle-calibre machine guns to supplement them. In the United States, the [[M2 Browning (12.7 mm)|M2 Browning]], which emerged from a World War I era development program, came to serve as the main armament of aircraft in both the US Army Army Corps and US Navy. However, overseas the Europeans were working on developing aircraft armed with more powerful explosive cannons. While the development of these weapons also began during World War I, the 1930s marked the period where the designing of cannon-armed fighters began in earnest. The United States was not one to fall behind and first developed the [[M4 (37 mm)|37 mm M4]] cannon for aircraft use. However, the gun suffered from a low muzzle velocity and short range. Therefore it was only used in service on the [[P-39 (Family)|P-39]] and [[P-63 (Family)|P-63]] interceptors before a replacement was sought.

 The British Government would come to the aid of the United States in the search for a replacement when they requested the United States produce the [[Hispano Mk.I (20 mm)|20 mm Hispano Mk.I]] under license. This cannon was itself a licensed version of the French [[Hispano 404 (20 mm)|Hispano 404]] cannon. The British would ultimately not select the American-designed M1 cannons due to the fact they were unreliable. The problem was later found to stem from the use of a longer chamber as the 20 mm was seen as artillery by United States doctrine and built to looser tolerances. Jamming presented the additional problem of throwing the plane's aim due to the uneven recoil forces of having a single cannon firing. The United States Army Air Corps would adopt the M1, but the problems led to the later adoption of the 20 mm AN/M2. The AN/M2 differs primarily in terms of the dimensions and some of the receiver parts. The M2 uses receiver slides with a projection that fits into a receiver side slot and the slide is held in place by a cotter pin. The receiver is also .02 inches longer than the M1 gun.

-The AN/M2 was planned to become a standardized armament for American aircraft during World War II. The conversion was set to begin once enough cannons and ammunition were available, but it would be too late during the war for the conversion to occur. As a result, the fighters of World War II were still chiefly armed with large numbers of M2 Browning machine guns. The AN/M2 would still see action but in special roles on interceptors such as the [[P-38 (Family)|P-38 Lightning]], night fighters such as the [[F6F-5N|F6F-5N Hellcat]], and [[P-61A-1|P-61 Black Widow]], and bombers such as the [[B-29A-BN|B-29 Superfortress]] and [[SB2C (Family)|SB2C Helldiver]]. It still saw use on a small number of fighters later in the war specifically with the [[F4U-1C|F4U-1C Corsair]] used by the Marines at Okinawa.
