The Royal Navy formally introduced the Merlin HM1 helicopter into service on 1 December at RNAS Culdrose, where the aircraft will begin flying trials with the Intensive Flying Trials Unit, 700M Squadron.

The squadron, which is likely to operate four Merlins, will be responsible for introducing service operating procedures and training personnel, as well as for assessing the future potential of the aircraft.

The naval Merlin is a joint project between Lockheed Martin ASIC, the lead contractor, and GKN Westland. The navy has so far received seven Merlins, which have been used for performance, support and electromagnetic compatibility trials. A total of 44 Merlins is due to be received by the RN by 2001, with the first front line squadron in service in the latter half of the same year. The programme is worth around £1.5 billion ($2.5 billion).

The Merlin features an advanced mission system including Marconi Blue Kestrel search radar, Marconi/Thomson-CSF dipping sonar, Marconi AQS 903 acoustic processor, Racal Orange Reaper electronic support measures and a datalink, an innovation for RN helicopters. The three-engined helicopter will operate from the RN's three Invincible-class light carriers and Type 23 frigates.
