NEXT GENERATION LAUNCH VEHICLE

Firefly Beta is an evolutionary design based on Firefly Alpha technology. Beta is a 2-stage launch vehicle capable of delivering 11,000 kg to a 200 km (125 mile) Low Earth Orbit and has the capability of achieving Geosynchronous Transfer Orbits.

The Beta vehicle utilizes technologies such as all carbon composite tanks, heritage LOx/RP-1 liquid fueled engines and builds on other elements of the existing Alpha architecture. Firefly Beta will have lowest cost per kg to orbit of all launch vehicles in the 8,000 kg and under class.
