Me Bf 109 E-2
- E-2 (Limited production, additional Motorkanone engine mounted MG FF cannon, otherwise as E-3)
Only very limited numbers of the E-2 variant were built, for which the V20 prototype served as basis. It was armed with two wing mounted, and one engine mounted Motorkanone MG FF cannon, which gave considerable trouble in service, as well as two synchronized MG 17s cowl machine guns. In August 1940, II./JG 27 was operating this type.
