| Summary | CASIC's road-mobile, quick-response small solid launcher, operated commercially by ExPace since 2017 — one of the higher-cadence Chinese small-lift vehicles. | 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 liquid-biomethane orbital smallsat launcher from Interstellar Technologies, Japan's most established private rocket startup by suborbital flight heritage, though not yet flown to orbit. |
