“The Lockheed AH-56 Cheyenne was a single-engine attack helicopter developed by Lockheed for the United States Army‘s Advanced Aerial Fire Support System (AAFSS) program to produce the Army’s first dedicated attack helicopter. Lockheed designed the AH-56 utilizing a four-bladed rigid-rotor and configured the aircraft as a compound helicopter; with low-mounted wings and a tail-mounted thrusting propeller. The Cheyenne was powered by a GE T64 turboshaft engine and was intended to provide a 212-knot (244 mph, 393 km/h) dash capability in order to serve as an armed escort to the Army’s transport helicopters, such as the UH-1 Iroquois…”
