Responsive Small Launch Services

Ready for Launch

Firefly’s small-lift rocket, Alpha, is equipped to launch more than 1,000 kg to low Earth orbit in support of commercial, civil, and national security missions. The flight-proven vehicle is designed to be a responsive, reliable, and cost-competitive launch option, enabling direct, on-demand deliveries when and where customers need to fly. Alpha can be launched domestically or internationally through Firefly’s launch facilities at the Vandenberg Space Force Base in California and new launch capabilities coming soon at the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, Virginia in 2025 and at the Esrange Space Center in Sweden starting 2026.

Repeatable Reliability for Your Mission

Manufactured entirely in the USA, Alpha utilizes our patented tap-off engine cycle, which reduces complexity with fewer parts and improves reliability compared to staged combustion or gas generator cycles. We also utilize advanced carbon composite technologies for Alpha’s entire airframe and cryogenic propellant tanks, enabling a strong, lightweight vehicle at value prices.
