| Summary | Primary launch vehicle for Cygnus ISS cargo missions from 2013–2023. Its Ukrainian-built Zenit-derived first stage and Russian RD-181 engines became untenable after the 2022 invasion of Ukraine. Northrop switched NG-20 onward to Falcon 9 while Antares 330 (with Firefly Miranda engines) is in development. | 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 primary small satellite launcher derived from Vega. The P120C first-stage motor is shared with Ariane 6's solid strap-on boosters. Avio took over programme management from Arianespace in Dec 2025. |
