Focke-Achgelis Fa 325

The Focke-Achgelis Fa 325 Krabbe was a proposed rotary wing transport designed in Nazi Germany by Focke-Achgelis in 1942.

Design and development
Heinrich Focke began designing the Fa 325 for the Kriegsmarine, which was interested in a torpedo-armed helicopter. The design had four rotors, and was, effectively, two Focke-Achgelis Fa 223 Draches attached to each other, powered by two Bramo 301R-3 radial engines (BMW development of the Bramo 323 Fafnir engine for helicopter use). Empty weight was calculated at 9250 kg, and maximum take-off weight at 12268 kg. The Kriegsmarine leadership withdrew from the Fa 325 project in 1943, and Focke ceased further development.
