H2O2/Hydyne propellant. Hydrogen peroxide and Hydyne would have represented a storable propellant combination with higher density than the usual nitric acid or N2O4 and hydrazine. Hydyne was a propellant blend of 60% UDMH and 40% diethyltrianine (DETA). It was pushed rather vigorously by the Redstone arsenal in the late 1950's, but found little application.
