The EH101 Merlin Mk 3 is the newest RAF helicopter, the RAF having ordered 22 EH101 (Merlin) support helicopters for £755m in March 1995.

Merlin is a direct replacement for the Westland Wessex, and it operates alongside the Puma and Chinook in the medium-lift role.

Its ability to carry troops, artillery pieces, light vehicles and bulk loads, means that the aircraft is ideal for use with the UK Army's 16 Air Assault Brigade. Deliveries took place between 2000-2002.

The aircraft can carry a load of 24-28 troops with support weapons. The maximum payload is 4,000 kg and Merlin has a maximum range of 1,000 km, which can be extended by external tanks or by air-to-air refuelling. The Merlin Mk 3 has sophisticated defensive aids, and the aircraft is designed to operate in extreme conditions with corrosion-proofing for maritime operations. All weather, day/night precision delivery is possible because of GPS navigation, a forward-looking infra-red sensor and night vision goggle compatibility. In the longer term, the aircraft could be fitted with a nose turret fitted mounting a .50 calibre machine gun.

During March 2007 the UK MoD announced the acquisition of 6 x additional Merlin Mk 3A from Denmark.

In 2013, a Merlin Life Sustainment Programme was in its Assessment Phase. This upgrade assessment looked at options to enhance the Merlin Mk3/3A aircraft's ability to support amphibious operations.

Following an upgrade we would expect Merlin 3/3A aircraft to remain in service until 2030.

All the above aircraft are under the control of the Joint Helicopter Command (JHC).
