The British Army’s Apache attack helicopters, built by Boeing [BA], operated by the Army Air Corps, flew their 50,000 hour on operation in Afghanistan recently the Ministry of Defense (MoD) said.

This represents a third of all U.K. Apache flying, a huge proportion of the total, MoD said April 14.

Apache helicopters have been conducting operations in Afghanistan since 2006, deploying initially with 16 Air Assault Brigade, shortly after being introduced into service with the British Army. Since then the aircraft have been constantly deployed on Operation Herrick, the United Kingdom’s name for operations in Afghanistan, where they provide support to ground forces, tactical strike, reconnaissance, and armed escort to other helicopters.

To maintain Apache’s high tempo of operations, the aircraft are fully supported by air and ground crews from the Army Air Corps (AAC), and technicians from the Royal Electrical and Mechanical Engineers (REME). All these soldiers perform a vital function, keeping the aircraft serviceable and airborne.

The current detachment, 664 Squadron AAC, part of 4 Regiment AAC, is commanded by Maj. Simon Wilsey, who actually flew the 50,000th hour.

“The operational tempo we have maintained over the last eight years has been challenging, but the resilience of our soldiers, and especially that of their families supporting them, is outstanding. I am proud and lucky to command such high caliber, professional soldiers and such an amazing capability as the Apache,” Wilsey said.

The Apache will continue to play a key role with 16 Air Assault Brigade once operations in Afghanistan draw to a close and the brigade starts to focus on readiness for contingency operations.

Commander of the Joint Aviation Group, Col. Jaimie Roylance of the Royal Marines, said: “This immaculately versatile machine has, for nearly 8 years, been the most clinically precise and effective attack helicopter when it has needed to be. But, equally, and sometimes at the same time, it has been the most wonderfully effective keeper of the peace, and protector of the vulnerable in its escort and deterrent roles.”
