| Summary | 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. | 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 next-generation medium-heavy rocket replacing Atlas V. Powered by two BE-4 engines on the first stage and a cryogenic Centaur V upper stage. Primary customer is USSF under NSSL Phase 2. |
