Merlin Mk 1

Submarine Hunter

Merlin Mk1 – the world’s most potent submarine hunting helicopter. The Merlin Mk1 have been in service with the Fleet Air Arm since the late 1990s and, after thorough testing and evaluation, the helicopters have been on the front line since 2000.

Beyond searching for submarines, we carry out traditional maritime helicopter duties: anti-piracy/drug-running patrols, surveillance and reconnaissance, srch and rescue, and passenger and load transfers.

There are more than 40 Merlins in service with the Fleet Air Arm in training and front-line squadrons. 

Most of these are in the middle of a £750m upgrade to turn the Merlin Mk1 into the Merlin Mk2 which has more powerful computer systems and is easier for aircrew to operate.
