Merlin Helicopters
Nicholas Soames: To ask the Secretary of State for Defence when the RAF Merlin Mark 3 will be transferred to the Royal Navy. [60876]
Mr Robathan: We intend to upgrade and transfer our current fleet of Merlin Mk 3/3a helicopters to the Royal Navy: the first upgraded helicopters will enter service with the Commando Helicopter Force in time to replace the Sea King Mk 4 helicopters, which are planned to be withdrawn from service in 2016.
