EL SEGUNDO, Calif. - The U.S. Space Force’s Space Systems Command has awarded two additional launches under the National Security Space Launch Phase 3 Lane 1 program to enhance national missile tracking capabilities.
Scheduled to begin in the third quarter of fiscal year 2027, the two launches will deploy payloads from Cape Canaveral Space Force Station in Florida and Vandenberg Space Force Base in California under the $178.5 million SDA-4 task order awarded to SpaceX.
The launches will place dozens of Sierra Space-built satellites into orbit as part of a distributed missile tracking system designed for rapid data delivery and resilience. This system is intended to improve detection, tracking, and warning of missile threats across multiple orbits.
