Prince William has qualified as an operational search and rescue captain in the Royal Air Force.
He passed with flying colours the two day military assessments that concluded on 29 May.
It now means the future British Monarch will be able to fly Sea King helicopters and command search and rescue operations.
The Prince lives at the RAF base in Anglesey, North Wales with wife Kate Middleton, and has been part of operations with the 22 squadron since September 2010.
