H2O2/UDMH
H2O2/UDMH propellant. Hydrogen peroxide is used as both an oxidizer and a monopropellant. Relatively high density and non-toxic, it was abandoned after early use in British rockets. It was proposed for use with Unsymmetrical Dimethylhydrazine, the storable liquid fuel of choice by the mid-1950's. Having no advantage over the usual oxidizer used with UDMH, N2O4, it did not find application in any production engines.
