Coke used a corner of the aircraft carrier's Bridge Wireless Office, a Telegraphist who wrote down the RDF reports from the cruisers, and a Bigsworth Board, a portable device used by air observers, which was roughly two feet across and had pantograph-plotting arm fitted, which was a small mechanical device to solve the wind triangle.

Initially, only the incoming enemy's location, course, and airspeed was passed to the aircraft carrier's fighters.

However, Coke later worked out how he could track the carrier's fighters, with dead reckoning and a regular radar check, enabling him to order the course, airspeed and sometimes altitude to intercept.

[4] Coke attended the Naval Air Division in the Admiralty in May 1941 to arrange for his next duty, after completing his tour on Ark Royal.

Following on from his experiences, he was posted to RNAS Yeovilton (HMS Heron), in Somerset, to set up fighter direction school with a programme and he devised a three-week training course of theoretical and practical tasks.

The civilian company, Airwork Services Ltd, was then contracted to provide the live interception flights from January 1950, operating out of RNAS Brawdy and its satellite, RAF St Davids.

This was known as the Air Direction Training Unit (ADTU) and it initially operated with de Havilland Sea Mosquito and Taylorcraft Auster V aircraft.

[8] The RN School of Meteorology, moved from the Royal Naval College, Greenwich to HMS Harrier in October 1946.

[10] The meteorological training relocated to RNAS Culdrose (HMS Seahawk), where it later included Oceanography, after fourteen years at Kete.

Over the next decade the school operated at Kete until July 1960, when it transferred to HMS Dryad (shore establishment).

The rating training moved to RNAS Culdrose (HMS Seahawk) in 1959, and this was followed by the officers’ courses, along with the rest of the school, during 1960.

In July 1960 the Radar Plotter Training relocated to HMS Dryad (shore establishment), and by the end of the year the Aircraft Direction Officer Training had returned, after fifteen years at Kete, to RNAS Yeovilton (HMS Heron).
