Regarding the citation needed about rocket fuels, page 12 of the book "Ignition!" by John Drury Clark says:
"Very little propellant development was involved in the A-4. From the beginning, liquid oxygen was the intended oxidizer, and 70-30 alcohol-water mixture (as had been used by the VfR) the fuel. And Helmuth Walter's 80 percent hydrogen peroxide was used to drive the fuel pumps. The peroxide entered a decomposition chamber, where it was mixed with a small quantity of a solution of calcium per-manganate in water. This catalyzed its decomposition into oxygen and superheated steam, which drove the turbines which drove the pumps which forced the oxygen and the alcohol into the main combustion chamber."
So it's not really a component of the rocket fuel, but rather, a catalyst for decomposing hydrogen peroxide that in turn powers the fuel pumps for the rocket fuel.
