This complex included two launch pads 18A and 18B. Pad 18A was used to launch 14 Vanguard space vehicles for NASA and the U.S. Navy between 8 December 1956 and 19 September 1959. Pad 18B supported 17 Thor missile launches between 4 June 1958 and 1 March 1960. Following termination of the Vanguard program, Pad 18A supported ten Blue Scout Junior launches for the Air Force between 21 September 1960 and 10 June 1965. Pad 18B supported half a dozen Blue Scout I, Blue Scout II and Scout missions between 7 January 1961 and 13 April 1962. Complex 18 was deactivated on 1 February 1967.
