| 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. | Europe's flagship launcher replacing Ariane 5. The Vinci re-ignitable upper stage enables multi-orbit missions and controlled deorbit. Primary customers: Amazon Kuiper, European government payloads, and ESA science missions. |
