This Westland Sea King HC Mk.4 aircraft was built to standard 4/Y/1 under a Ministry of Defence contract and was the 15th aircraft of a total of 39 built for operation in the troop transport role by the Royal Navy. It first flew on 20th September 1982 and was delivered to the Royal Navy on 2nd October 1982.

The history of its usage from 1982 to 1998 is not known as the relevant documents were not supplied with the aircraft.

Since 1998 the aircraft has been operated at various times by 845, 846 and 848 Naval Air Squadrons from bases including Yeovilton and Croatia and from ships including HMS Ark Royal and HMS Ocean. Its final operational base was Boscombe Down where the aircraft was used by QinetiQ between April 2013 and December 2015.

Further investigation of the aircraft’s history between 1982 and 1998 was not considered necessary as the information on its maintenance and operational status since 1998 is complete and all necessary overhauls and other maintenance activities have been carried out.

When withdrawn from service in December 2015 it had accumulated 10,182:25 hours of its 20,000 hour life.  It was purchased in June 2019 and registered G-CMDO on 17th June 2019.
