AH-56 Cheyenne

English: AH-56 Cheyenne was an unsuccessful, but sophisticated military attack helicopter which was designed as a replacement for the interim AH-1 Cobra. The AH-56 was intended to correct the AH-1's deficencies in speed, survivability and firepower. The AH-56 is an interesting aircraft in that it is not a true helicopter, combining features and characteristics of both a conventional helicopter and fixed-wing aircraft - sometimes known as a compound helicopter.
