| Summary | Australia's first domestically developed orbital launch vehicle attempt, using a hybrid-propellant first and second stage; the maiden flight failed 14 seconds after liftoff in July 2025. | 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. | Europe's primary small satellite launcher derived from Vega. The P120C first-stage motor is shared with Ariane 6's solid strap-on boosters. Avio took over programme management from Arianespace in Dec 2025. |
