The MG 81 was a German belt fed 7.92 mm machine gun, used in flexible installations in World War II Luftwaffe aircraft, replacing the older drum magazine-fed MG 15.
The MG 81 was developed by Mauser as a derivative of their successful MG 34 infantry machine gun. Development focus was to reduce production cost and time and to optimize for use in aircraft. Developed in 1938/1939, it was in production from 1940 to 1945.
A special twin-mount MG 81Z (the Z suffix stands for Zwilling - meaning "twin") was introduced in 1942. It paired up two of the weapons on one mount to provide even more firepower with a maximum rate of fire of 3200 rounds/minute without requiring much more space than a standard machine gun.
Applications[]
The MG 81Z can be found in many unique installations in the Luftwaffe. Some of the more known applications, are a pair of MG 81Z's installed in the hollow tail cone of the Dornier Do 217. Designated R19 (R for Rüstsatz) as a factory designed field conversion/upgrade kit, it allowed the pilot of the Do 217 to shoot at pursuers. Another application was the "Watering can", an externally mounted pod with 3 sets of guns and ammo meant to be attached to a Junkers Ju 88 and used to strafe ground targets.
