| 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. | The world's most frequently flown orbital rocket. Block 5 first stages have landed over 280 times and reflown up to 23 times. Backbone of Starlink and commercial crewed launches. | 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. |
