Space Launch Complex 2 (SLC-2) is an active rocket launch site at Vandenberg Space Force Base, in California, USA. It consists of two launch pads: SLC-2E (originally LC 75-1-1), used by the PGM-17 Thor and several of its derivatives from 1958 to 1972, and SLC-2W (originally LC 75-1-2), which is currently used by the Firefly Alpha after historically being the west coast launch site of the Delta II.

Space Launch Complex 2 was originally part of Launch Complex 75 (LC 75) and was known by designation LC 75-1 or just 75-1 (and the launch pads were designated LC 75-1-1 and LC 75-1-2). The first launch out of the newly designated Space Launch Complex 2 was that of a Delta E with ESSA-3 on 2 October 1966 from SLC-2E.^[1]

SLC-2E and SLC-2W are located approximately 2,000 feet (610 m) apart.^[2]
