Propellant mix is slush LH2/RP-1/LOX. LH2 and LOX are used to cool the spikes before entering the combustion chamber. The tanks are either HC-based, or made of 3D molded titanium and epoxy, and are protected by Linar. They are 31M in height, 4M in diameter, multi-celled, and are housed on either side of the cargo bay. At least 200MT of propellant is required.
Fuel weight stabilization is achieved by both passive and active means. Multi-celled fuel tanks help to distribute the weight of the LH2/LOX mix, equally accross the aircraft. Fuel lines are ±10CM in diameter with a 167+M/s flow speed, and are lined at either end of the tanks.
