The Focke-Achgelis Fa 223 Drache ("Dragon" in English) was a helicopter developed by Germany during World War II. A single 750 kilowatt (1,000 horsepower) Bramo 323 radial engine powered two three-bladed 11.9 metre (39 feet) rotors mounted on twin booms on either side of the 12.2 metre (40 ft) long cylindrical fuselage. Although the Fa 223 is noted for being the first helicopter to attain production status, production of the helicopter was hampered by Allied bombing of the factory and only 20 were built.
