SDA Procurement Lags as Pentagon Moves to Dissolve Agency

The Space Development Agency (SDA) is facing a critical juncture as the Pentagon prepares to shutter the semi-autonomous organization and integrate its procurement pipeline into the U.S. Space Force, according to Ars Technica. Lawmakers in both houses of Congress have supported the agency's closure in drafts of this year's National Defense Authorization Act.

Established in 2019 to bypass traditional bureaucracy, the SDA was tasked with deploying the Proliferated Warfighter Space Architecture (PWSA)—a constellation of missile warning and data relay satellites in low-Earth orbit designed to track ballistic and hypersonic missiles. While the agency aimed for monthly launches, Ars Technica reports the mission has been hindered by supply chain bottlenecks, production delays, and technical failures.

Recent deployments have been particularly fraught. Following launches in September and October of last year, the SDA stood down for nine months. Gurpartap “GP” Sandhoo, director of the SDA, told reporters that satellites manufactured by Lockheed Martin and York Space Systems faced propulsion and thermal control issues while ascending to an operational altitude of over 600 miles. Sandhoo noted that the radiation environment at 1,000 kilometers caused orbit-raising to be "sporadic." Additionally, ground controllers lacked sufficient station coverage to communicate with the spacecraft.

Despite these setbacks, a SpaceX Falcon 9 rocket launched a third group of data transport satellites from Vandenberg Space Force Base on Thursday, bringing the Tranche 1 transport total to 63. The full Tranche 1 architecture is intended to include 154 satellites: 126 for data relay and 28 for missile tracking. Much of this capability will eventually support the Trump administration's "Golden Dome" missile shield, a top Space Force priority.
