In 1956 the United States were permitted to extend to sites on Ascension Island the Long Range Proving Ground already established in the Bahamas to track guided missiles fired from Cape Kennedy. This year they were also permitted to establish a station to track space craft. The conditions governing both facilities are contained in White Papers (Cmnd. 9810 and Cmnd. 2741). There is also a purely temporary facility for air/sea rescue in connection with the Gemini space flight.
