The 2nd Space Launch Squadron is an active United States Space Force unit. It is located at Vandenberg Space Force Base, California, and was reactivated in July 2019 with the merger of the 4th Space Launch Squadron and the 1st Air and Space Test Squadron.


When founded, the two launch squadrons at Vandenberg Air Force Base divided launch duties, with the 4th Space Launch Squadron working with Titan II and Titan IV vehicles while the 2nd worked with Delta II, Atlas, and other launch vehicles. On 18 May 1998, the two squadrons merged into the 2nd SLS. The merged squadron was responsible for all launch operations at Vandenberg AFB. The reason for the merger was the similarity in missions performed by both units. It was inactivated after the last Titan IV launch. In June 2019 the 4th Space Launch Squadron and the 1st Air and Space Test Squadron merged and reactivated as the 2nd Space Launch Squadron. The reestablished unit took on all the missions of both the 1st Air and Space Test Squadron and the 4th Space Launch Squadron. the 2nd Space Launch Squadron was one of only two space launch squadrons in the U.S. Air Force. the other being the 5th Space launch Squadron at Cape Canaveral.[3]

Both space launch squadrons are now part of the U.S. Space Force.
