The AH-64A assault helicopter was the first to start production. The crew sits side by side in an armored compartment. The ship is powered by two GE T700 turboshaft engines. The 701 engine was utilized in the A-model until 1990 when it was replaced by the 701C version, which was more powerful. On September 25, 2012, Boeing was awarded a $136.8 million contract to remanufacture the last 16 AH-64As into the AH-64D Block II version.
