Find the best place to watch the launch from Vandenberg
Space Launch Complex 4E has witnessed the launch of 248 rockets, including 248 orbital launch attempts. While Vandenberg SFB, CA, USA, has been the site for 862 rocket launches.
Vandenberg Space Force Base is a United States Space Force Base in Santa Barbara County, California. Established in 1941, Vandenberg Space Force Base is a space launch base, launching spacecraft from the Western Range, and also performs missile testing. The United States Space Force's Space Launch Delta 30 serves as the host delta for the base, equivalent to an Air Force air base wing. In addition to its military space launch mission, Vandenberg Space Force Base also hosts space launches for civil and commercial space entities, such as NASA and SpaceX.
Rocket
SpaceX Falcon 9 Block 5
Falcon 9 is a two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of satellites and the Dragon spacecraft into orbit. The Block 5 variant is the fifth major interval aimed at improving upon the ability for rapid reusability.
Landing
Core B1063
B1063 has landed back at the launch site after this flight. Booster B1063 last launched 12/17/2025 and has seen 30 successful launches and landings. Notable launches include Sentinel-6 and Dart.
A sonic boom is likely to occur a few minutes after launch as the booster returns to the launch site. Be prepared for a loud but thrilling experience! Learn more about rocket launch sonic booms
Landing Zone 4 - LZ-4
LZ at Vandenberg
Return to Launch Site - RTLS
A return to launch site usually means that after stage separation the booster flips and does a burn back towards the launch site, landing near where it initially launched from.
Agency
SpaceX
Space Exploration Technologies Corp., known as SpaceX, is an American aerospace manufacturer and space transport services company headquartered in Hawthorne, California. It was founded in 2002 by entrepreneur Elon Musk with the goal of reducing space transportation costs and enabling the colonization of Mars. SpaceX operates from many pads, on the East Coast of the US they operate from SLC-40 at Cape Canaveral Space Force Station and historic LC-39A at Kennedy Space Center. They also operate from SLC-4E at Vandenberg Space Force Base, California, usually for polar launches. Another launch site is being developed at Boca Chica, Texas.
