The Comanche was intended to be an advanced armed reconnaissance and attack helicopter. The Comanche was specifically tailored to the role of armed scout to replace the U.S. Army's OH-58D Kiowa Warrior, which is an upgraded version of a Vietnam War-era observation helicopter. It was both smaller and lighter than the AH-64 Apache attack helicopter that it had been intended to accompany. The RAH-66 was powered by a pair of LHTEC T800 turboshaft engines, each capable of generating up to 1,563 hp (1,165 kW) of power. The RAH-66's fuselage was long and composed of composite materials; it was designed to be capable of fitting more readily onto transport ships, enabling the Comanche to be more rapidly deployed to flash points and other rapidly-developing situations. However, in the event of strategic transport assets not being available, the helicopter's ferry range of would have allowed it to fly itself to battlefields overseas on its own.
