York Space Systems
Designs, mass-manufactures, and operates standardized spacecraft platforms and end-to-end mission solutions for national security and commercial constellation customers
York Space Systems is a publicly traded defense and space prime contractor that designs, mass-manufactures, and operates standardized spacecraft platforms for government and commercial constellation missions. The company produces three satellite bus families: the S-CLASS for ESPA-compatible smallsat constellations, the LX-CLASS for medium payloads up to 300 kilograms, and the M-CLASS for large earth-observation and communications missions exceeding 1,000 kilograms of payload mass. All three platforms share a common technology baseline that streamlines production and supply chain management.
York serves as a primary supplier to the Space Development Agency's Proliferated Warfighter Space Architecture, delivering transport layer satellites with Link-16 connectivity and optical inter-satellite links. The company completed delivery of 21 Tranche 1 Transport Layer spacecraft in 2025 and demonstrated space-to-ground laser communications. Through its acquisition of ATLAS Space Operations, York operates a global ground station network of over 50 antennas across 20-plus countries via the Freedom GSaaS platform. Its Bastion ground software and Multi-Mission Operations Center provide constellation-scale command and control. Founded in 2014 and headquartered in Greenwood Village, Colorado, York went public on the NYSE in January 2026.
