Gravitics

Gravitics designs and manufactures large space structures for commercial and national security applications, including space station modules, orbital carriers, and cargo logistics spacecraft. Founded in 2021 and headquartered in the Seattle metropolitan area, the company operates a fabrication facility in Marysville, Washington, employing a shipyard-style manufacturing approach with shared tooling across its product lines.

The company's StarMax module provides approximately 400 cubic meters of pressurized habitable volume in a 7.6-meter diameter, 9.8-meter tall aluminum structure, representing one of the largest standalone spacecraft interior volumes under development. StarMax units can function independently or interconnect as building blocks for larger orbital stations. Gravitics holds a $125 million contract with Axiom Space to provide pressurized utility spacecraft for the Axiom Station.

On the defense side, Gravitics develops the Diamondback and Medusa orbital carriers, designed to pre-position and protect maneuverable space vehicles for rapid tactical response. The companion Viper OTX orbital transfer vehicle supports payload delivery to MEO, GEO, and cislunar orbits. The U.S. Space Force selected Gravitics for a STRATFI program worth up to $60 million to demonstrate orbital carrier technology, and the Missile Defense Agency awarded the company a SHIELD IDIQ contract in January 2026. All products share a common 4-meter diameter form factor with interchangeable components, enabling dual-use across commercial station infrastructure and defense missions.
