History
The site was originally planned as a satellite station for RAF Exeter for No. 10 Group of RAF Fighter Command. Construction started in the summer of 1941. The landing strip was grass rather than tarmac and few permanent buildings apart from the control tower and two blister hangars, with aircraft being protected by blast pens. Ground defence was provided by the Somerset Light Infantry.
It opened as an RAF station on 10 July 1942 and was made available for use by the Royal Navy and 886 and 887 Squadrons, who flew Fairey Fulmars were the first to occupy the site, soon to be replaced by 790 Naval Air Squadron. Various squadrons subsequently used the station either while undergoing training and preparation for service or for fighter interception training for Air Direction Radar operators or flight controllers who were trained at RNAS Yeovilton (HMS Heron).
In August 1942 891 Naval Air Squadron transferred from RNAS Lee-on-Solent where it had been formed to Charlton Horethorne with six Sea Hurricanes to prepare for carrier operations, later transferring to RNAS St Merryn and then embarking on HMS Dasher to take part in Operation Torch. Other squadrons posted to the base during 1942 included: 782, 879 and 809 Naval Air Squadrons.
On 1 December 1942 Charlton Horethorne was formally transferred from the RAF to the Admiralty and designated as HMS Heron II. In 1943 a new watch tower was built, more runways laid out in the grass and further hangars built. Further squadrons were temporarily stationed at the base with 780 Squadron staying the longest. In 1945 the base was taken over by RAF Maintenance Command who used it for storage until the end of 1947. It then became a satelitte training field for RAF Old Sarum and kept on a Care and Maintenance basis until it was de-requisitioned and returned to farmland.
A number of units were here at some point:
