Relativity Space is a Launch Vehicles company founded in 2015 and based in Long Beach, United States. It has raised $2.4B in total funding, most recently a Series F in 2023.

A second Chinese launch company successfully lands an orbital-class reusable booster, marking rapid progress in China's reusable rocket race.
Two-stage, partially reusable medium-lift launch vehicle powered by 13 Aeon R liquid-oxygen-methane engines, targeting the LEO constellation market with a first launch from Cape Canaveral. Primary structures use friction-stir-welded aluminum, while engines are manufactured via Relativity's Stargate powder-bed-fusion and wire-arc additive platforms, enabling a fast print-to-build cycle. Terran R is positioned as a Falcon 9-class competitor, and Relativity has booked nearly $3B in launch contracts against it as of 2025.
Proprietary large-scale metal 3D printing system combining laser powder bed fusion and wire-arc additive manufacturing to produce rocket engine and structural components. It is designed to cut part count from tens of thousands to hundreds and compress production lead times from years to weeks. Stargate systems at Relativity's Long Beach factory manufacture Aeon R engines and structural hardware for Terran R, demonstrating factory-scale additive manufacturing applied directly to aerospace production.
15 patents on file, but none with both an extractable figure and an abstract on Google Patents yet.
