Space Launch Complex 3E
SLC-3E is a launch pad at Vandenberg Space Force Base. It was originally built for the MIDAS program and later used for various other missions. After a period of inactivity, it was refurbished in the early 2000s to launch Atlas V rockets. The pad is now being upgraded to accommodate the new Vulcan Centaur rocket. The last Atlas V launch from SLC-3E happened in November 2022, with the first Vulcan launch expected in 2025.
