York Space Systems (York) has received first contact and has confirmed the healthy status of all 21 satellites launched on September 10 from Vandenberg Space Force Base in support of the Space Development Agency’s (SDA) Proliferated Warfighter Space Architecture (PWSA) Tranche 1 Transport Layer (T1TL) mission.

Deploying and confirming the health of 21 satellites within hours of launch is a historic milestone. The achievement demonstrates the scalability and reliability of York’s space vehicle production and operations model, supporting SDA’s goals of resilient, low-latency satellite communications are available to U.S. and allied warfighters.

York is the first of the prime contractors selected for the T1TL mission to launch and deploy. York will complete its T1TL contract launch and deployment campaign with an additional 21 satellites later this year. York is proud to continue to support SDA as it fields this critical capability for national security space.

York’s rapid first-contact success was powered, in part, by ATLAS Space Operations’ (ATLAS) software-led ground architecture. Acquired by York earlier this year, ATLAS provides a fully U.S.-owned, globally distributed ground station network and mission planning software. This integrated capability enables York to connect with its spacecraft faster and more efficiently than ever before. By streamlining connectivity across an expanding ground network, York is delivering the infrastructure required to rapidly field resilient defense architectures like Golden Dome and ensure decision advantage for the warfighter.

Confirming health so quickly across 21 satellites is proof that York’s high-rate production paired with disciplined mission operations delivers results. This success further highlights York’s central role in enabling the DOD’s vision for a proliferated architecture that ensures resilience and decision advantage for the warfighter,” said Melanie Preisser, VP and GM of York.
