Space Launch Complex 5 (SLC-5) was a launch pad at Vandenberg Space 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.

Satellites launched from the complex included Transit, OV3, Explorer and P35 (DMSP) spacecraft.

Between 2009 and 2012, the original complex architecture was demolished and was left untouched for the rest of the decade.

In 2024, it was announced that the United States Space Force had leased the site to Phantom Space Corporation for their Daytona line of launch vehicles,[1] with its inaugural launch slated for Q4 2025.
