The Army specified that the AAH was to be powered by twin General Electric T700 turboshaft engines that produce 1,500 shp (1,120 kW) each. The T700 was the same powerplant fit specified for a new Army utility helicopter competition that would be won by the UH-60 Black Hawk. The AAH would be armed with a 30 millimeter cannon and 16 TOW anti-tank missiles. The missile armament specification was later modified to include an alternate load of 16 laser-guided AGM-114 Hellfire anti-tank missiles. The Hellfire was then in development and promised greater range and lethality than TOW.
