The AH-64 is a two-seat attack helicopter powered by two General Electric T700 turboshaft engines, with high-mounted exhausts on either side of the rotor shaft. The crew sit in tandem, with the pilot sitting behind and above the gunner. The crew compartment is armoured against 20mm gunfire. The helicopter is armed with a 30mm M230 chain gun which is slaved to the gunner's helmet-mounted gunsight. The AH-64 carries a range of external stores on its stub-wing pylons, typically a mixture of AGM-114 Hellfire anti-tank missiles Hydra 70 general-purpose unguided 70mm rockets, and AIM-92 Stinger anti-aircraft missiles for defence. In case of emergency the pylons also have mounting points for personnel transfer
