The AH-64 Apache is the United States Army's principal attack helicopter, and is the successor to the AH-1 Cobra. The AH-64 is powered by two General Electric T700 turboshaft engines.

The crew sits in tandem, with the pilot sitting behind and above the copilot-gunner in an armored crew compartment. The AH-64 is armed with a 30 mm M230 chain gun and carries a mixture of AGM- 114 Hellfire and Hydra 70 rockets on four hard points mounted on its stub-wing pylons.

Designed by Hughes Helicopters in response to the Army's Advanced Attack Helicopter Program, it was built to endure front-line environments and to operate during the day or night and in adverse weather using avionics and electronics, such as the Target Acquisition and Designation System, Pilot Night Vision System,(TADS/PNVS), passive infrared countermeasures, Global Positioning System (GPS), and the Integrated Helmet And Display Sight System (IHADSS).
