| Summary | South Korea's first domestically developed and produced launch vehicle, designed entirely without foreign engine technology. Nuri TF4 (Nov 2025) was the first launch managed by Hanwha Aerospace rather than KARI — marking the transition to commercial operation. KASA (Korea Aerospace Administration) took over programme oversight in 2024. | JAXA's small solid-fuel rocket derived from the M-V rocket heritage. Designed for highly autonomous operations — launch preparations could be managed by just 8 people. The sixth and final E-6 mission (Oct 2022) failed when the PBS kick stage didn't ignite; a ground explosion during Epsilon S testing (Jan 2023) ended the programme. | ULA's workhorse from 2002–2024. Launched Mars Science Laboratory (Curiosity), OSIRIS-REx, Solar Orbiter, Lucy, New Horizons, and the Boeing Starliner. Its Russian RD-180 first-stage engine became a political liability after 2022; last flight was the Amazon Kuiper testbed on Apr 9, 2024. |
