Defense forces worldwide fly two variants of the AH-64 multimission combat helicopters: the AH-64A Apache and the next-generation version, the AH-64D. Equipped with radar, the aircraft is known as the AH-64D Apache Longbow. Without radar, it is the AH-64D Apache. (In the U.K., where all next-generation Apaches will have radars, Apaches are in production by AugustaWestland. The British Army will field these aircraft under the designation AH-Mk1.)
The AH-64D Apache Longbow is the newest version of the combat-proven AH-64A Apache and fulfills attack helicopter and reconnaissance requirements of several armed forces worldwide. It can perform loops, left and right rolls and turns, split S and hammerhead maneuvers, and 360 degree turns, all while flying at full mission weight of approximately 16,000 pounds.
