This is a Hurricane class heavy lift rocket with over 2000 ton payload capacity to LEO. I made it using existing rocket engines and srb`s. First stage has 24 RD 171 engines and 18 Space Shuttle srb`s. Second stage has 19 RS-68 engines modified for optimal vacuum use.
You will need multistage 2 and spacecraft 3 for this addon to work. Fuel MFD is needed if you want to pump fuel from included fuel tank payload.
