Sierra Space is a Colorado-based defense technology company with more than three decades of heritage, developing space systems for U.S. national security, civil, and commercial customers, as well as global allies. Its work spans satellite platforms, critical subsystems, propulsion systems, hypersonic technologies, and infrastructure for national security missions.
The company operates two flagship programs. Dream Chaser is a winged, reusable commercial spaceplane - claimed to be the only one of its kind. LIFE (Large Integrated Flexible Environment) is a large-scale inflatable habitat designed for commercial space stations. Together, these programs represent Sierra Space's push into reusable launch and long-duration space infrastructure.
Beyond its flagship programs, Sierra Space supplies a broader portfolio of flight-proven hardware across the defense and civil space sectors, including satellite platforms, propulsion systems, and hypersonic technologies. The company describes its customer base as encompassing U.S. national security agencies, civil space programs, and international partners.
