A process for casting propellant paste into a mould to manufacture a block of solid propellant includes first mixing two groups of components briefly at low pressure, mixing the two groups of components at high pressure, and casting the mixture in a mould. The first group of components represents about 80% to about 99% of the finished product and essentially comprises a liquid prepolymer, at least one pulverulent solid charge and some of the various additives of the propellant paste. The second group of components represents about 20% to about 1% of the finished product and comprises the crosslinking agent and the rest of the additives.
