A Fairey Gannet aircraft is being transported to St Athan today. The post-WW2 plane was designed to fly from aircraft carriers. Maintenance work will be carried out on the aircraft by Hunter Flying Ltd in Barry.
After winning the contract to take over search and rescue helicopter cover from the RAF, Bristow Helicopters have released details of the new fleet that will be deployed in April 2015.
There will be two helicopters at both its Welsh bases -Caernarfon Airport and the MOD site at St Athan near Barry.
Caernarfon's Sikorsky helicopters will cover an area of 250 nautical miles around the base and each carry three stretchers and up to 10 seated casualties. Augusta Westlands will cover 200 nautical miles around St Athan and each have room for two stretchers and six seated casualties.
All the helicopters will have a crew of four and be capable of flying at 145 nautical miles an hour.
St Athan will become the key training area for aerobatic display teams from around the UK. Hunter Flying Ltd oversees the maintenance and operation of the largest private collection of classic aircraft of its kind in the world - many of which are used by display teams at airshows.
Hunter Flying relocated its entire operation to South Wales this year as a planned expansion at Exeter Airport, its former base, meant it had to find new premises. Hunter flying is the first private business to move into St Athan Aerospace Business Park.
