Firefly

Firefly-α [Firefly Space Systems]

Firefly is a small liquid fueled orbital launch vehicle, which is being developed by Firefly Aerospace, Inc.. Both stages are Kerosene and LOX fueled and pressurized by Helium.

After Firefly Space Systems, which was developeing the first version of the Firefly launch vehicle, was closed due to a law suit concerning intellectual property rights, the assets were taken over by the newly formed Firefly Aerospace, Inc., which restarted the Firefly development without using the contested aerospike design.

The first stage is powered by four of the Firefly built Reaver engines. The second stage is to be propelled by the Lightning engine.

As a launch site for polar orbits, the SLC-2W complex at Vandenberg AFB, which currently still hosts Delta vehicles, is planned to be modified for the Firefly vehicles. For low inclination orbits no launch site has been chosen. Candidates are Cape Canaveral, Florida, the proposed Spaceport Camden on Georgia’s Atlantic coast, and the Mid-Atlantic Regional Spaceport at Wallops Island, Virginia.

The basic Firefly-α (Firefly Alpha) vehicle carries up to 1000 kg payloads to low earth orbit. A Firefly-β (Firefly Beta) featuring two more core stages as boosters will deliver about 4000 kg to low earth orbit at a later date.

A maiden launch of the Firefly-α is planned for 2019.
