Tim Ellis and Jordan Noone founded the company in 2015 to build rockets with 3D-printed engines and structures, manufactured on proprietary Stargate metal printers at the Long Beach, California headquarters. Terran 1 flew once in March 2023 and failed to reach orbit after an upper-stage anomaly, prompting a pivot to the larger, partially reusable Terran R powered by 13 Aeon R engines. Eric Schmidt acquired a controlling stake and replaced Ellis as CEO on March 10, 2025, after the firm struggled to close new funding. Terran R targets a first flight no earlier than 2026 from Launch Complex 16 at Cape Canaveral, against a reported $2.9 billion order backlog.
