The Maschinengewehr 30, or MG30 was a German-designed machine gun that saw some service with various armed forces in the 1930s. It was also modified to become the standard German aircraft gun as the MG15 and MG17. It is most notable as the design pattern that led to the MG34 and MG42, and thus is one of the major ancestors of many of the weapons in service which would later find widespread use even into the present day.
Further modification in 1936 led to the MG17, which included provisions for belt-fed ammo in addition to the drums, increased the rate of fire to about 1,200 rpm, and was suitable for use with an interrupter gear for shooting through the aircraft's own propellor.
In 1942 aircraft guns had increased dramatically in size, and the 7.92 mm weapons were no longer considered useful by the Luftwaffe. Many were then sent to the army, who started a program to modify them into ground-based weapons by adding a bipod and simple metal stock.
