What widely used on aircraft in the 1930s through 1950s was the result of the development of the M-25?
Wright R-1820 Cyclone The Wright R-1820 Cyclone 9 was an American radial engine developed by Curtiss-Wright, widely used on aircraft in the 1930s through 1950s. It was produced under license in Spain as the Hispano-Suiza 9V or Hispano-Wright 9V, and in the Soviet Union as the Shvetsov M-25.
Focke-Wulf Fw 200 Condor The Focke-Wulf Fw 200 "Condor", also known as "Kurier" to the Allies, was a German all-metal four-engined monoplane originally developed by Focke-Wulf as a long-range airliner. A Japanese request for a long-range maritime patrol aircraft led to military versions that saw service with the "Luftwaffe" as long-range reconnaissance and anti-shipping/maritime patrol bomber aircraft. The Luftwaffe also made extensive use of the Fw 200 as a transport.
