The case-bound OPAL composite solid propellant charge had a star shape channel. The case was of organic fibre-wound plastic material. The gimbaled engine nozzle partially intruded into the combustion chamber. Steering was accomplished moving the nozzle, mounted on a circular elastic hinge, in pitch and roll. Versions of the motor seem to have been manufactured by both Tsurilnikov in Russia and Yuzhnoye in the Ukraine.
