The MG14 German Parabellum Machine Gun was designed and implemented in 1913. Designed primarily as an aircraft armament weapon. The Parabellum was also the first German Gun to be properly "synchronized" to the primary prop of a fighter, by famed aircraft designer Anthony Fokker. Weighing just 18 pounds, it was a forward mounted fixed weapon, capable of a sustained rate of fire of 700 rounds per minute. The Parabellum fired both the 7.9mm round. Later in the War, it was the primary defense weapon for Zeppelin crews. The Parabellum also was chosen as the main armament for one of Germanys first prototype Mono-planes, The Fokker E1.
