Relativity Space

Relativity Space manufactures the Terran R, a heavy-lift launch vehicle designed for high-cadence, reusable orbital delivery. The two-stage rocket utilizes the Aeon R engine, which burns liquid methane and liquid oxygen. Terran R provides a payload capacity of 23,500 kilograms to low Earth orbit in its reusable configuration and up to 33,500 kilograms when flown expendably. The company leverages its proprietary Stargate technology, a large-scale metal 3D-printing system that integrates artificial intelligence and autonomous robotics to manufacture complex aerospace structures with significantly reduced part counts. Relativity operates from its 1-million-square-foot headquarters and manufacturing facility, known as the Wormhole, in Long Beach, California.

The company maintains launch infrastructure at Space Launch Complex 16 at Cape Canaveral Space Force Station and Launch Complex 4 at Vandenberg Space Force Base. Relativity serves a diverse customer base including commercial satellite constellation operators and government agencies such as NASA and the U.S. Space Force. Following the 2023 flight of Terran 1, the first predominantly 3D-printed rocket to reach space, the company shifted its primary focus to the Terran R platform. In March 2025, former Google CEO Eric Schmidt assumed the role of chief executive and took a controlling stake in the privately held firm to lead its commercial scaling and development efforts.
