In the early 1980s it was thought the UK could be wiped out with use of ~15% of the total Soviet nuclear arsenal. It was also assumed there would be a nuclear, chemical and conventional war across Europe and Turkey. America chose to deploy in Europe from 1983 up to 464 USAF Gryphon Ground Launched Cruise Missile (GLCMs) that were based on the US Navy BGM-109 Tomahawk cruise missile, as well as 108 US Army Pershing II ballistic missiles. Some SLCM and ALCM were also deployed. RAF Molesworth and Greenham Air Base were the recipients of the non submarine launched missiles."@en . . .
