| 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. | 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). |
