A Short History of the MG 81

Development of the MG 81 began in the late 1930s as a successor to the MG 15 machine gun. Mauser designed the MG 81 to address the need for a lightweight, reliable, and high-rate-of-fire weapon for aircraft armament. Introduced into service in the early 1940s, the MG 81 quickly became a staple armament for Luftwaffe aircraft.

The MG 81 was praised for its robust construction, ease of maintenance, and relatively high rate of fire, making it effective for both offensive and defensive roles in aerial combat. It saw extensive use on various German aircraft throughout World War II, contributing to the firepower of fighters, bombers, and reconnaissance planes.

As the war progressed, the MG 81 remained in service alongside other machine guns such as the MG 131. Its reliability and adaptability ensured its continued use until the end of the conflict, despite advancements in aircraft armament technology.
