The AH-64 Apache is the United States Army's principal attack helicopter, and is the successor to the AH-1 Cobra. It was designed by Hughes, was further developed by McDonnell Douglas, and is currently produced by Boeing.
The AH-64 is a two-seat attack helicopter powered by two General Electric T700 turbo-shaft engines. The crew sit in tandem, with the pilot sitting behind and above the copilot-gunner in an armored crew compartment. The helicopter is armed with a 30mm M230 chain gun and carries a mixture of missiles and rockets on its stub-wing pylons.
