Israel used the Apache in its military conflicts in Lebanon and the Gaza Strip. American AH-64s have served in conflicts in Panama, the Persian Gulf, Kosovo, Afghanistan, and Iraq. It has been built under license in the United Kingdom as the AgustaWestland Apache. It has also become the primary attack helicopter of multiple nations, including Greece, Japan, Israel, the Netherlands, Singapore, and the United Arab Emirates.

Army is the primary operator of the AH-64. Production has been continued by Boeing Defense, Space & Security, with over 2,400 AH-64s being produced by 2020. The advanced AH-64D Apache Longbow was delivered to the Army in March 1997. After purchasing Hughes Helicopters in 1984, McDonnell Douglas continued AH-64 production and development. Army selected the YAH-64 over the Bell YAH-63 in 1976, and later approved full production in 1982. The prototype YAH-64 was first flown on 30 September 1975. The Apache began as the Model 77 developed by Hughes Helicopters for the United States Army's Advanced Attack Helicopter program to replace the AH-1 Cobra. The AH-64 has significant systems redundancy to improve combat survivability. It is armed with a 30 mm (1.18 in) M230 chain gun carried between the main landing gear, under the aircraft's forward fuselage, and four hardpoints mounted on stub-wing pylons for carrying armament and stores, typically a mixture of AGM-114 Hellfire missiles and Hydra 70 rocket pods. It features a nose-mounted sensor suite for target acquisition and night vision systems.

The purpose of this is for power saving as the sleep mode is essentially a low current mode. Deep Sea Electronics Contol Modules have built in sleep mode that is similar to that found commonly on many electrical devices.
