Relativity Space
Overview
Vertically integrated 3D-printed rocket manufacturer. Pivoted from small Terran 1 (reached space March 2023 but did not achieve orbit) to larger reusable Terran R. SES multi-launch agreement ($200M+) secured as anchor customer. Aeon R engine completed 25+ successful hot fires at Stennis Space Center. First Terran R flight targeting NET Q1 2027.
Moat: World's largest metal 3D printers (Stargate) enable rapid design iteration at a fraction of traditional tooling cost. Terran R's partially 3D-printed reusable first stage targets Falcon 9 payload class at lower per-unit manufacturing cost. SES anchor contract provides $200M+ revenue visibility.

Near-term Catalysts
- 2026
Terran R first stage completion and engine integration
Major manufacturing milestone on path to first flight
- 2027 Q1
Terran R first flight
Validates 3D-printing manufacturing approach at orbital scale; unlocks SES and government revenue
Top Risks
- No orbital flights yet — significant execution risk before first Terran R launch
- Delay from 2026 to 2027 first flight target; further delays could pressure SES contract
- Funding gap risk if additional capital needed before first flight generates revenue
- SpaceX Falcon 9 and Rocket Lab Neutron target similar medium-lift market segment
