WASHINGTON — Firefly Aerospace on Oct. 18 said it is collaborating with Aerojet Rocketdyne to increase the performance of its upcoming Alpha launch vehicle, and is considering Aerojet Rocketdyne’s AR1 engine for a future launch vehicle.
Cedar Park, Texas-based Firefly said its debut Alpha rocket, set to launch in the first quarter of 2020, will feature 3D-printed components from Aerojet Rocketdyne on its first-stage Reaver engines.
The company’s second vehicle, Beta, may use the AR1 engine Aerojet Rocketdyne previously promoted as an option for United Launch Alliance’s Vulcan rocket, the two companies said.

Their Feb 2020 goal wound up being derailed but they are finally starting to make progress. Payload to LEO is 2000lbs at $15M price.

First stage integrated test. 165 thousand pounds of total thrust (4 engines).

So now they are starting to dream of future plans including this.

Firefly Aerospace’s Alpha rocket ready for first launch

The rocket could have been ready sooner but for the delayed delivery of a component needed for its flight termination system. Markusic declined to identify the specific component or its supplier, but said it was one of the few major components that the company did not develop in-house.

“The vendor could not get the components qualified and delivered on time,” he said. “We’re a year behind schedule on that flight termination system.”

I checked with Firefly, whose first Alpha launch is scheduled for Thursday from Vandenberg, and they say they have no issues with consumables that would delay their launch.

Firefly Alpha first stage engine use a unique system to power the Turbopumps
