Boeing AH-64 Apache

1st Flight 1975

The Boeing AH-64 Apache is an American twin-turbo shaft attack helicopter with a tail wheel type landing gear arrangement and a tandem cockpit for a crew of two.

It features a nose-mounted sensor suite for target acquisition and night vision systems.

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 hard points mounted on stub-wing pylons for carrying armament and stores, typically a mixture of AGM-114 Hellfire missiles and Hydra 70 rocket pods.

The AH-64 has significant systems redundancy to improve combat survivability.

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 prototype YAH-64 was first flown on 30 September 1975.

The U.S. Army selected the YAH-64 over the Bell YAH-63 in 1976, and later approved full production in 1982.

After purchasing Hughes Helicopters in 1984, McDonnell Douglas continued AH-64 production and development.

The helicopter was introduced to U.S. Army service in April 1986.

The advanced AH-64D Apache Longbow was delivered to the Army in March 1997.

Production has been continued by Boeing Defence, Space & Security, with over 2,400 AH-64s being produced by 2020.

The U.S. Army is the primary operator of the AH-64.

It has also become the primary attack helicopter of multiple nations, including Greece, Japan, Israel, the Netherlands, Singapore, and the United Arab Emirates.

It has been built under license in the United Kingdom as the Agusta Westland Apache.

American AH-64s have served in conflicts in Panama, the Persian Gulf, Kosovo, Afghanistan, and Iraq.

Israel used the Apache in its military conflicts in Lebanon and the Gaza Strip.

British and Dutch Apaches have seen deployments in wars in Afghanistan and Iraq.
