238 OCU, was detached to North Luffenham from RAF Leeming which was having its runways extended to 7000 ft to accommodate Gloster Javelins.

3GRSS was responsible for the third-line maintenance repair of all ground radar and radio communication/navigational and landing aids located at airfields throughout Great Britain and Northern Ireland.

The Centre was commanded by a senior RAF Medical Officer who with his medical and technical team were responsible for fitting and instructing aircrew in the use of flying protective clothing and equipment, including partial pressure suits, which kept the pilot conscious in the event of loss of cabin pressure at high altitude.

Instruction in medical aspects of high performance aviation included experience of hypoxia and exposure to sudden explosive decompression of an aircraft cabin.

This was carried out in a complex of RAF Mark V decompression chambers installed on the site for aircrew training and research purposes.

A plaque to commemorate the Language School was unveiled in 2005 by Air Commodore Bruce Benstead, the last Station Commander at RAF North Luffenham.
