Space Development Agency Reaches 83% Completion After Nine-Month Technical Pause

A SpaceX Falcon 9 rocket has launched 21 more satellites into polar orbit for the Pentagon’s Proliferated Warfighter Space Architecture, pushing the total on-orbit count to 105 of the 126 transport satellites required. The launch comes after a nine-month technical pause to address four categories of failures, including thermal behavior and electric propulsion issues. The program aims to deliver initial operational warfighting capability in 2027, with the activation of the optical inter-satellite link mesh remaining a key unresolved technical milestone. This development was first reported by Unknown Source.
