| Summary | 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. | A medium-lift successor to Firefly's Alpha, co-developed with Northrop Grumman, aimed at the national-security and commercial medium-lift gap between small launchers and heavy-lift vehicles. | ISRO's small-satellite launcher, designed for quick-turnaround dedicated smallsat missions. Full manufacturing, marketing and launch rights were transferred to Hindustan Aeronautics Limited in June 2025 under a technology-transfer agreement. |
