501 AH-64A Apaches upgraded to AH-64D standard have been delivered to the US Army.
The AH-64D Longbow is fitted with the Longbow millimetre wave fire control radar and the Longbow Hellfire missile. The AH-64D Longbow was deployed by the US Army in Afghanistan as part of Operation Anaconda, in support of Operation Iraqi Freedom and, from June 2003, in South Korea. It was used in Operation Desert Storm and has supported low intensity and peacekeeping operations worldwide including Turkey, Bosnia and Kosovo. The Apache was first used in combat in 1989 in the US military action in Panama.
The US Army has more than 800 Apaches in service, and more than 1,000 have been exported.
It entered service with the US Army in 1984 and has been exported to Egypt, Greece, Israel, the Netherlands, Japan, Saudi Arabia, United Arab Emirates (UAE) and the UK. The Apache is a twin-engined army attack helicopter developed by McDonnell Douglas (now Boeing).
