The Norderstedt EF-51 is an Acrean Great War-era piston fighter aircraft. Produced in very high volume throughout the 1930s, the EF-51 was one of the most advanced aviation designs in use when it first appeared in 1932. Throughout its service, the EF-51 was highly regarded for its remarkable engine performance and armament, using MD605 engines which produced over 2000 hp in later EF-51G and EF-51K series fighters.
