Current Status
Pivoted from small Terran 1 (first launch March 2023, reached space but not orbit) to larger Terran R. First flight hardware in production: thrust section complete, all 8 first-stage structural barrels welded, first 2 Aeon R flight engines finished. Aeon R qualification engine completed 11+ hot fires in May 2025 including 4 in a single day. SES signed multi-launch agreement.
Future Outlook
First Terran R flight targeted H2 2026. Delayed NSSL (National Security Space Launch) bid to focus on debut. Positioned as medium-lift competitor to Falcon 9 with 3D-printing manufacturing advantage for rapid iteration. Raised $1.2B+ total funding.
