Relativity Space
Manufactures reusable medium-to-heavy-lift launch vehicles using large-scale metal 3D printing and autonomous robotics
Relativity Space designs and manufactures reusable launch vehicles at its headquarters in Long Beach, California. The company's primary vehicle, Terran R, is a medium-to-heavy-lift rocket delivering 23,500 kg to low Earth orbit in its reusable configuration and 33,500 kg expendable, powered by Aeon R methane-oxygen engines.
The company developed Stargate, a proprietary large-scale metal 3D-printing platform integrating AI and autonomous robotics, though under new leadership has shifted toward more traditional manufacturing alongside additive techniques. Relativity maintains launch infrastructure at Cape Canaveral and Vandenberg Space Force Base. The company has secured over $3 billion in launch service agreements from commercial and government customers. In March 2025, former Google CEO Eric Schmidt assumed the role of chief executive and took a controlling stake.
