Note: Note: | There were two variants: MG FF (A) with mechanical trigger, for movable mounting, the trigger operated by the shooter. MG FF (B) with electric launcher, designed for fixed installation. The supply of the cannon ammunition was carried out from a short in-line magazine for 15 grenades or from drum magazines with a capacity of 30, 45, 60, 75 and 100 rounds. The weight of the empty drum magazine for 60 grenades 8.2 kg, full weighed 20.3 kg. A more efficient Minengeschoss ammunition was developed for the MG FF cannon, which gave rise to the modernized MG FF/M (ammunition was not interchangeable). Both types of MG FF and MG FF/M cannons were mounted in fighter aircraft as fixed weapons, when installed in the wing of the aircraft caused problems quite a large drum magazine. For aircraft Fw 190 A-1 to A-5 was the usual combination of modern cannons MG 151/20 with MG FF cannons and more often with MG FF/M, but it is true that the MG FF and MG FF/M cannons were often dismantled for units to save weight. This weapon also had its comeback, in the years 1942 - 1943 it was mounted on the fuselages of night fighters such as Schräge Musik. | The 0.79in MG-FF cannon has been created by firm "Erlicon". It was applied in wing and turret variants. Wing cannon had ammunition load on 60 or 100 cartridges, turret - on 15 or 30 or 45 cartridges. The MG FF and FF/M saw widespread use in fighters such as the Bf 109 E-3 to F-1, Bf 110 C to F, and Fw 190 A-1 to A-5. The Fw 190 was typically fitted with an inboard pair of MG 151 and an outboard pair of MG FF, although the MG FF were sometimes removed in the field in order to save weight.The cannon was also fitted to bombers such as the Do 217, Ju 88, He 111, Do 17, as well as many other aircraft. Although the MG FF was often replaced with the 0.79 in MG 151/20 from 1941 onwards, it saw a come-back in 1943 as the primary Schräge Musik gun in the Bf 110 night fighters, as it perfectly fitted into the rear cockpit. |
