The US Department of the Air Force is reviewing its procurement of low Earth orbit military satellites, potentially replacing the planned 140 satellites for the Proliferated Warfighter Space Architecture (PWSA) Transport Layer Tranche 3 with SpaceX's Starshield satellites. This decision, impacting the 2026 budget, aims to reduce costs. While the first two tranches of PWSA remain funded, concerns about reduced competition and vendor dependence on SpaceX have been raised by lawmakers. The Air Force is analyzing alternatives, but no final decision has been made.
