Terran 1 was our first pathfinder vehicle, a two-stage small-lift launch system that made its debut and launched in March 2023.

Terran 1 demonstrated our ability to simultaneously develop novel technologies while planning, designing, testing, and operating an orbital-class launch vehicle. Building on this foundation, we are now focused on Terran R, our medium-to-heavy lift reusable rocket. Key engineering learnings from the Terran 1 program – including LOX methane propulsion systems, gas generator combustion cycles, guidance, navigation, and control algorithms, in-house developed flight software, structural dynamics, and aerothermodynamics – are directly relevant to the Terran R vehicle.
