Operational Use
The main types to utilise the Type M2 were large aircraft - the Friedrichshafen G.III bomber and AEG G.IVk ground-attack machine. Tests in smaller, single-engined aircraft were not so successful, but were carried out extensively through the rest of the war, commencing with an Albatros J.I in December 1917. Due to the gun's operating principles, it could not be synchronised, and this posed an immediate problem for its installation in this type of plane. The solution adopted after the tests with the Albatros J.I was to mount the gun at an angle to fire downwards. Fitting the gun to a fighter with a pusher configuration was another obvious solution, and trials were carried out with an Albatros D.VI. Other intended installations were for an AGO C.I and the Hansa (Caspar) D.I, but these were not carried out before the Armistice.
Total production figures are not known, but were in excess of 539; a total of 362 were surrendered to the Allies.
