 EH101 MERLIN HM Mk1

A merlin EH101 helicopter performs a flypast of Norfolk and Invincible

Merlin was ordered in the early 1990s in a contract worth £1.5 billion and the first of 44 production aircraft appeared in 1996 and Merlin was accepted into service in 1999.

The Royal Navy currently operates 38 x aircraft (with four in reserve) in the anti-submarine and anti-surface warfare role in 5 x squadrons (814, 820, 824, 829 and 700 Sqns). All are based at RNAS Culdrose. When embarked the aircraft can operate from almost any capable flight deck.

The aircraft has a state-of-the-art mission system, which processes data from an extensive array of on-board sensors, giving Merlin an independent capability to search for, locate and attack submarine targets. It is this autonomous capability which makes Merlin almost unique among Anti Submarine Warfare helicopters.

Merlin’s operational debut came during operations in the Northern Gulf and Southern Iraq during 2003. The planned out of service date for the Merlin Mk 1 is 2029.
