    Flag Officer Sea Training Fleet Air Arm

    Flag Officer Sea Training
    Flag Officer Sea Training (FOST) is the certifying body for the RN that its units and those of the Royal Fleet Auxilliary (RFA) are competent to join the fleet for operational tasking. In its basic form (BOST), this means crews can find their way around the ship or submarine in darkness or smoke and that they can handle the craft in a safe and efficient manner. Advanced operational training teaches crews to fight the vessel and manage any damage, to maximum effect. It also teaches key elements of disaster relief and logistics support.
    As part of its Advanced training and evaluation programmes, FOST arranges realistic exercises around the British Coast, mainly in the English Channel and Western Approaches. It is aided in this by the participation of many naval and air units (from Flag Officer Surface Flotilla, Flag Officer Submarines, the Royal Fleet Auxilliary and Flag Officer Naval Aviation) plus a comprehensive communications infrastructure, including the coastal radar from the ex-gunnery school at HMS Cambridge, just to the east of Plymouth.
    FOST was formed at Portland in 1958 but after the 1999 base closure, moved its HQ to the HMS Drake shore establishment at Devonport. It used to maintain a small air taxi operation from the nearby Plymouth Airport until this closed in Dec 2011. This is now run from HMS Raleigh during the day with the helicopters repositioning to Newquay for overnight hangarage. The unit has detached underwater specialists on the Clyde and staff specialists at Northwood (HMS Warrior).
    FOST's expertise is recognised worldwide and approximately one third of its work involves training visiting foreign naval units.
    Flag Officer Sea Training is not formally part of the Fleet Air Arm, but it is convenient to list it here.
