| Summary | 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. | 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. | LandSpace's enhanced methalox launcher, the higher-performance successor to the original Zhuque-2 (the first methalox rocket ever to reach orbit, in 2023) — see slug 'zhuque-2' for the original vehicle already in our database. |
