In September 2025 York Space Systems deployed 21 satellites for the Space Development Agency’s Tranche 1 within hours of launch.
York Space Systems is a primary contractor for the Space Development Agency’s Tranche 1 Transport Layer.
The acquisition of Orbion is a strategic response to increasing demand for the Space Development Agency’s Proliferated Warfighter Space Architecture (PWSA).
Sierra Space holds an SDA Tranche 2 Tracking Layer contract with a maximum potential value of $740 million to build 18 missile warning, tracking, and fire control satellites.
The SDA is considering shifting planes of satellites between vendors and potentially moving a second batch of York Space Systems satellites onto an earlier launch slot if Lockheed Martin requires more time for troubleshooting.
The SDA centralized payload processing by replacing individual vendor-managed plans with an integrated SDA-led coordination model to alleviate processing chokepoints.
The next SDA launch, originally slated for late 2025, is now tentatively targeted for late March or April 2026 pending resolution of software readiness issues and the SpaceX anomaly investigation.
The Government Accountability Office issued report GAO-26-107085 on January 28, 2026 finding that the SDA is overestimating the technology readiness of its tracking layer and lacks a unified architecture-level schedule to track how individual tranche delays impact global missile defense capabilities.
The Space Development Agency released a status update on March 5, 2026 that identifies significant hurdles in scaling its Proliferated Warfighter Space Architecture (PWSA).
