| 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. | Rocket Lab's medium-lift reusable rocket targeting the $100B constellation replenishment market. Uses a 'hungry hippo' fairings design that opens at the top rather than traditional clamshell separation. First flight delayed to Q4 2026 after a Jan 2026 propellant tank test anomaly. | A two-stage medium-lift launcher originally designed with a reusable combined-booster-recovery concept in mind, though currently operational vehicles fly expendable. Exclusively from Wenchang. |
