Description
These are electrically initiated, surface-to-surface, fin- and spin-stabilized rockets using an M-21OF or M-21OFM high-explosive fragmentation (HE-frag) warhead (the warheads differ only in the type of HE).
The 9M22U rocket may have an optional spoiler ring, either 90 or 112 millimeters (3.50 or 4.40 inches) in diameter, in the circumferential groove and held in place by a snapring; the 9M22M has only been observed with the larger ring. When installed, the spoiler ring decreases the range and dispersion of the rockets. The igniter leads of the 9M22U electrically connect the igniter to the closure plate and nozzle block. The leads extend from the igniter retainer and are routed through the lower propellant grain and the center hole of the nozzle block. One lead is attached to a nozzle block contact screw and the other lead to a closure plate contact screw. The closure plate contact screw attaches the igniter lead to a metal strip molded into the outer surface of the closure plate. The metal strip covers one-third of the plate rim. It extends across the top and to the center of the closure plate, where it is attached to the internally mounted contact screw. In the 9M22M the igniter leads extend about 305 millimeters 12.00 inches beyond the nozzle and terminate in a 2-prong plug.
The warhead is painted light or dark gray, and the rocket motor is painted light or silver gray. All markings are black, with the exception of a red-stamped symbol 9 on the forward portion of the rocket motor. The warhead main charge explosive filler designation is stenciled on the warhead with the Cyrillic (Soviet) markings.
