Messerschmitt

Bf-109

Willy Messerschmitt's Bf 109 was the Luftwaffe's benchmark fighter throughout World War II. It was the mount of the vast majority of the German aces and scored more kills than any other Axis aircraft. Few fighters of the period bettered the Bf 109's longevity, either. The aircraft entered service in time to be blooded in Spain, and it remained the backbone of the Luftwaffe fighter arm until the end of the war.
