| Summary | Relativity Space's Falcon-9-class successor to Terran 1, partially 3D-printed, with 13 Aeon R methalox engines on a reusable first stage; second stage and fairing expendable. | ISRO's small-satellite launcher, designed for quick-turnaround dedicated smallsat missions. Full manufacturing, marketing and launch rights were transferred to Hindustan Aeronautics Limited in June 2025 under a technology-transfer agreement. | ULA's workhorse since 2002 and the longest-serving active US rocket. Launched Mars Science Laboratory (Curiosity), OSIRIS-REx, Solar Orbiter, Lucy, New Horizons, and the Boeing Starliner. Production ended in 2024 and ULA no longer sells the vehicle, but it continues flying a sold-out backlog of Starliner and Amazon Leo missions into the late 2020s. |
