| Summary | The world's most powerful solid-propellant launch vehicle and the largest rocket yet flown from a sea platform. Orienspace's barge-launched Gravity-1 gives Chinese commercial customers a mobile, weather-flexible ride for mid-inclination smallsat batches; both flights to date succeeded. | A Japanese commercial solid-fuel small launcher that has failed on all three flight attempts through March 2026, putting its commercial viability in serious question. | The larger sibling of Kuaizhou-1A, roughly 3.75x the payload class, road-mobile and solid-fueled, recovering commercial cadence after a 2020 debut failure. |
