York Space Systems Completes Successful Dragoon Mission Test Objectives

York Space Systems  a leading, US-based national defense and commercial prime providing a comprehensive suite of mission-enabling solutions, today announced the successful completion of initial Dragoon mission objectives. The mission proved that York’s spacecraft can both send and receive tactical data via UHF, which the U.S. military relies on for secure, real-time connectivity with assets in the field. Completing this two-way link from low Earth orbit (LEO) confirms York’s ability to deliver operationally relevant tactical communications at speed and scale, on a platform built for the demands of modern defense.

York satisfied initial mission exit criteria through five successful demonstrations over a three-month period, including three downlink demonstrations, which validated the spacecraft’s ability to transmit data down to a stationary government ground terminal, and two uplink demonstrations, which confirmed the ability to push most data from the ground back up to the spacecraft.

“Dragoon wasn’t just a technical exercise, it was proof that York can deliver space-based tactical communications that work,” said Melanie Preisser, GM and EVP at York. “Two-way connectivity between a satellite and ground forces is operationally essential, and we’ve now demonstrated it on orbit. That opens doors to mission sets that matter deeply to national defense.”

The ability to establish bi-directional tactical communications from a proliferated LEO platform is a meaningful addition to York's mission set portfolio. As the Department of War (DoW) accelerates its push toward resilient, distributed space architectures, the demand for proven suppliers who can deliver this kind of capability at speed and on orbit has never been greater. Dragoon positions York squarely at the center of that demand. Dragoon will continue with demonstrations for another quarter to test additional capabilities.

“This mission is emblematic of what York was built to do: take on hard missions, execute with precision, and deliver capabilities that directly strengthen U.S. defense posture,” added Preisser. “This success expands our proven mission set portfolio at exactly the right moment, as DoW looks to a capable, responsive industrial base to meet the demand for tactical space capabilities. York is ready to meet that demand.”

The successful completion of Dragoon expands York’s portfolio of eight unique mission sets aligned with national defense priorities and positions the company to capitalize on the approximately $20 billion in classified mission sets outlined in the DoW’s FY2027 mandatory budget. Notably, Dragoon leveraged an inventory spacecraft platform and delivered a complete mission to orbit in seven months, demonstrating that York can respond to emerging defense needs without sacrificing significant mission performance. To meet that demand, York has invested in an inventory of 20 spacecraft platforms, enabling delivery on timescales up to 75% shorter than current mission timelines. As the U.S. government continues to prioritize a broad and robust supplier base, York’s demonstrated UHF capability underscores its commitment to delivering missions that work, and to the enduring need for space-based tactical support for the warfighter.
