Designs and manufactures satellite platforms, reusable spaceplanes, expandable habitats, and propulsion systems for national security and civil space
Sierra Space designs and manufactures satellite platforms, spacecraft subsystems, reusable spaceplanes, propulsion systems, and expandable orbital habitats. The company produces satellite structures for the Space Development Agency's Proliferated Warfighter Space Architecture and builds spacecraft for classified national security programs.
The Dream Chaser is a lifting-body spaceplane that launches inside a rocket fairing and lands autonomously on conventional runways. The company is developing the Large Integrated Flexible Environment (LIFE), an inflatable habitat module that expands to 27 feet in diameter and provides approximately 300 cubic meters of pressurized volume. Sierra Space partners with Blue Origin on the Orbital Reef commercial space station program. Its VORTEX engine technology uses a coaxial vortex flow field for propellant mixing. A subsidiary of Sierra Nevada Corporation, the company has raised over $2 billion since 2021, including a $550 million Series C in March 2026 at a $5 billion valuation.
