The Becker Type M2 20 mm cannon was a German autocannon developed for aircraft use during World War I by Stahlwerke Becker. It was first mass-produced in 1916 and was installed in a variety of aircraft. It was the only German autocannon to see service in the air during the war.^[1]

The Becker also served as the pattern for the famous Swiss-built Oerlikon 20 mm cannon, which is in service to this day, and in a later form, was the original inspiration, through the Swiss design after World War I, for the World War II German Luftwaffe's MG FF (Maschinengewehr Flügel Fest, "fixed wing-mount automatic ordnance") 20 mm autocannon design.
