| 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. | NASA's human deep space launch vehicle for the Artemis programme. Uses heritage RS-25 shuttle main engines (4 per flight, expended). Block 1B with Exploration Upper Stage cancelled Feb 2026; Block 1 will fly through Artemis IV at minimum. | Primary launch vehicle for Cygnus ISS cargo missions from 2013–2023. Its Ukrainian-built Zenit-derived first stage and Russian RD-181 engines became untenable after the 2022 invasion of Ukraine. Northrop switched NG-20 onward to Falcon 9 while Antares 330 (with Firefly Miranda engines) is in development. |
