# Russian “kerosene” versus American “RP-1”

RP-1 rocket fuel is a "highly refined form of kerosene". Most of the literature I have seen refers to Russian rockets using kerosene, versus American rockets using RP-1 (*1).

Is there really such a distinction between the two programs (and why)?

(*1) In the appropriate stages/engines. Many other fuels are used for other purposes, but that is not the scope of this question.
