established in 1960 as an Electronic countermeasures (ECM) measurement and evaluation unit by RAF Bomber Command Headquarters (HQBC), High Wycombe. The unit measured the signal strength, frequency bandwidths and aerial performance of the operational Handley Page Victor and Avro Vulcan V bombers as they flew a course towards, over or away from the unit varying from straight-lines to polar patterns. Results were passed back to Operations Research Branch, (HQBC), BCDU at RAF Finningley and each aircraft's base for the Electronics Engineers and Technicians to review for performance improvement of each piece of equipment that was measured. The combined success of 112 S.U., BCDU at RAF Finningly and each of the aircraft's bases along with the Operations Research Branch at (HQBC) and technical support from RRE Malvern (later to become RSRE Malvern) was demonstrated by the V-force during the Operation Skyshield exercises and readiness through the Cuban Missile Crisis in the early sixties and subsequent exercises up to the time that the unit was closed in 1983. In the early 1980s, part of the Airport was upgraded in a £40 million upgrade and extension of the main runway and taxiways along with new hangars, to accept Panavia Tornado aircraft. By 1 April 1982 this work was completed, the buildings commissioned and RAF Stornoway was established once again in order to become a Forward Operations Base. After sixteen years in this role and also the end of the Cold War, the station was finally closed on 31 March 1998 and reverted to Stornoway Airport. After this some of the buildings were sold off, one becoming a Christian school, and others including the Nissen hut accommodation blocks were demolished. The runway remains in use as part of Stornoway Airport, and other parts of the site are used as a ground for holding stunt shows and vehicle exhibitions. Units The following units were also here at some point: No. 303 Ferry Training Unit RAF (December 1942 - March 1943) Detachment of No. 1693 (General Reconnaissance) Flight RAF (August 1944 - ?) RAF Stornoway in fiction RAF Stornoway is featured in the Tom Clancy novel, Red Storm Rising, as a base for RAF operations over the North Atlantic and against Soviet-held Iceland. Later the displaced carrier air wing from USS Nimitz is based there after the carrier sustains battle damage. Also mentioned in passing in Katherine Kurtz's Death of an Adept.
