Liquid fuel

Liquid Fuel is a fuel type commonly used by rocket engines.

Other fuel types in the game are Jet Fuel, RCS Fuel and Solid Fuel.

Fuel Containers

Liquid fuel can be pumped from a fuel tank to another fuel tank or engine connected via an FTX-2 External Fuel Duct.
The following tanks contain Liquid Fuel.

Liquid fuel and oxidizer density are both 5 kg/unit				Mass (t)					Liquid Fuel ()	Oxidizer ()

↑ Consumes monopropellant. (the density of monopropellant is less: 4kg/unit)
↑ Consumes liquid fuel only.
↑ The LFB KR-1x2 is a liquid fuel booster -- a combination of a "normal" engine and a fuel tank.
↑ The R.A.P.I.E.R. Engine is a combination of liquid fuel and jet engine. Only the liquid fuel engine properties are shown.
