York Space Systems, Inc. is a leading U.S.-based space and defense prime contractor specializing in the design, manufacture, and delivery of mission-critical satellite platforms and integrated space solutions. Founded in 2012 and headquartered in Denver, Colorado, the company provides end-to-end services encompassing spacecraft production, launch coordination, ground segment operations, and on-orbit mission control for national security, government, and commercial clients. York distinguishes itself through proprietary hardware and software that enable scalable, cost-effective satellites—produced at roughly half the cost of competitors—supporting complex requirements across the space ecosystem lifecycle. As the top provider to the U.S. Department of Defense's Proliferated Warfighter Space Architecture, with substantial revenue from Space Development Agency contracts and a $642 million backlog, York excels in rapid deployment, high-volume production, and innovations like Link-16 connectivity from space. Employing around 670 people under CEO Dirk Wallinger, it recently went public via an upsized IPO, trading as YSS, with plans to acquire a key supplier to bolster supply chain resilience. York's vertically integrated model drives efficiency in the evolving satellite industry, emphasizing agility, security, and global connectivity.
