The MG 81 is a German belt fed 7.92×57mm Mauser machine gun which was used in flexible installations in World War II Luftwaffe aircraft, in which capacity it replaced the older drum magazine-fed MG 15.
The MG 81 was developed by Mauser as a derivative of their successful MG 34 general-purpose machine gun. Development focus was to reduce production cost and time and to optimize the machine gun for use in aircraft. Developed in 1938/1939, it was in production from 1940 to 1945.
