History
During World War II, the French Hispano-Suiza Hs.404 became the standard Allied aircraft cannon. However, these nations were not idle during the war and worked to improve this design. In the United States, the Ordnance Department’s attempt to make an improved shorter version of their licensed-built AN/M2 cannons spawned the T31 and later the M3 which had reliability issues. When the reliability issues that plagued the American variants of the Hispano-Suiza continued, the newly independent United States Air Force would adopt a variant after World War II called the M24. In an attempt to improve reliability, the M24 uses an electric firing mechanism that allows for re-cocking of a lightly struck round. The M24 would be one of the replacements M2 and M3 Browning machine guns in aircraft use. It primarily served as the turret armament of post-war bombers starting with the B-36 Peacemaker, Boeing B-47 Stratojet, and B-66 Destroyer. Fighters would mostly find their machine guns replaced with the FFAR Mighty Mouse rockets under the belief that the Jet Age made cannon armament obsolete for interceptors due to insufficient range. However, a small number of aircraft such as the F-86K Sabre and the F-89B Scorpion still received cannons. The M24A1 variant differs from the standard M24 through the bolt retainers for holding the shell casing, breech block side plate contacts for alternative synchronization methods, a new breech block with heat treatment and a changed angle, a flat spring on the firing pin contact for better contact, a reduced diameter breech block slide coil spring and spring guide, a new locking system for the gas cylinder, a two-part guide-spring, a new design and heat treating for barrel and breech block locking key, a large cotter pin for the magazine, a modified gas tube to accommodate the new contact plates, and a short slot to house the new breech block contact. The service life of the M24 was short. The United States captured data on the German Mauser MG 213 revolver autocannon which was used as the basis of the FMC T-160 tested during the Korean War and later the M39 revolving cannon adopted in 1952. The M39 would replace the M24 in Air Force service.
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
