[L]ittle is known about the specifications and operation of the system, but, according to the Head of Science and Research Center at NPO Mashinostroenia Leonard Smirichevsky, who introduced the weapon, the vehicle’s grenade-like solid propellant charges doubled as engines! RussianSpaceWeb.com’s 3D recreation of the displayed variant established that it held 96 casings with solid propellant arranged in a globular fashion like the petals of a dandelion around a central combustion chamber. Upon their ignition, the chambers/grenades might have fed hot propulsive gas into a single or multiple combustion chambers at the center of the contraption, producing either the main thrust and/or steering the vehicle. When the missile reached the proximity of the target, according to its guiding radar, the entire vehicle would explode and the small solid chambers would eject under their own propulsive force in every direction acting as shrapnel.

The missile had a flight range of about 70 miles, and was designed to destroy any hostile satellite or spacecraft that approached the military station.
