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.
