Aerospace/Defense

Based in Cedar Park, TX, Firefly is developing a family of low-cost, high-performance, dedicated small satellite launchers to extend humanity’s reach into the universe. Our team consists of highly experienced aerospace engineers that have spent the better part of the past decade working at various NewSpace companies, including SpaceX, Blue Origin and Virgin Galactic. Firefly’s flagship launch vehicle, Alpha, is a 2-stage rocket with variants capable of delivering 400-840kg payloads to Low Earth Orbit (LEO) utilizing efficient technologies including all-composite propellant tanks, an annular aerospike, & conventional engines running Liquid Oxygen (LOx)/hydrocarbon propellants. Developmental operations are highly streamlined with design and engineering, manufacturing, test-site and ground processing all located in central Texas. To maximize commercial opportunity, Firefly must “get there first”. This fundamental consideration drives the selection of technologies in the design of Alpha. The second consideration is fielding a vehicle with game-changing low launch costs. These factors demand a “simplest-soonest” approach to tech selection.
