| Success rate | 83.3%as of [2]5/6 successes. E-6 (Oct 12, 2022) PBS upper stage failed to ignite, eight satellites lost. Epsilon S (next-generation) ground test anomaly Jan 2023 effectively ended the programme. | 98%as of [2]49/50 successes. Only failure: F6 (Nov 2003, MTSAT-1R lost due to SRB separation anomaly). Retired after Flight 50 (GOSAT-GW, Jun 28, 2025). ↑ Best | ~55%as of [2]IFT-1 through IFT-11; ~6 complete mission successes, remainder partial or vehicle lost. No orbital payload deployment yet. |

| Summary | 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. | Japan's flagship medium-lift rocket for 24 years, retiring after an exceptional 49/50 mission success record. Launched the SELENE lunar orbiter (2007), Akatsuki Venus probe (2010), Hayabusa2 (2014), SLIM lunar lander (2023), and the ALOS series Earth observation satellites. | Largest and most powerful rocket ever flown. Super Heavy booster uses 33 Raptor engines. V3 Ship introduced Aug 2025. Mechazilla caught the booster on IFT-5 (Oct 2024) and IFT-10 (Aug 2025). Primary vehicle for Artemis HLS lunar landing (Artemis III planned 2026). |
