Ascension Island will release a set of 4 stamps to commemorate 7oth Anniversary of RAF.On 1 April 1918, the Royal Navy Air Service (RNAS) merged with the Royal Flying Corps (RFC) to form the Royal Air Force (RAF) and with this merger, some 238 motor boats moved to the RAF Marine Craft Section to support their newly acquired flying boats and for limited Search and Rescue operations. At the time, there was little specialist equipment and certainly no central organisation to support aircrew lost at sea, with their rescue being very much reliant on passing naval or merchant ships.
Today, the UK maintains a year-round, 24-hour SAR capability through its Search and Rescue Force which not only has its helicopters of 22 and 202 Squadrons located at six sites, but also helicopters from the Royal Navy and Maritime Coastguard Agency. The RAF Mountain Rescue Service has existed since 1943 and Teams are based at RAF Valley, Kinloss, Leuchars and Leeming. Each Mountain Rescue Team is manned by a core of permanent staff and volunteer RAF personnel.
