On Saturday, September 2 at 7:25 a.m. PT, SpaceX launched the Space Development Agency’s second Tranche 0 mission to low-Earth orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California. The space vehicles launched during this mission will serve a part of SDA’s Proliferated Warfighter Space Architecture, a new layered network of satellites in low-Earth orbit and supporting elements that will provide global military communication and missile warning, indication, and tracking capabilities. This was the thirteenth launch and landing of this Falcon 9 first stage booster, which previously launched Sentinel-6 Michael Freilich, DART, Transporter-7, Iridium OneWeb, and eight Starlink missions.
