Space Launch Complex 5 (SLC-5) was a launch pad at Vandenberg Air Force Base in California, United States. It was previously part of the Point Arguello Naval Air Station, during which time it was designated Launch Complex D or LC-D. Constructed in 1961, it was used by 69 Scout rockets between 1962 and 1994. Satellites launched from the complex included Transit, OV3, Explorer and P35 spacecraft. Most of the satellites launched from SLC-5 were placed into low Earth orbits, or low medium Earth orbits.
