The 13.55-ton SA-13 is built atop the existing hull and chassis of a slightly modified MT-LB multipurpose armored tracked carrier and therefore retains the same YaMZ-238 V diesel-fueled 240 horsepower engine and performance specifications of 37 miles per hour road speeds and 310 mile operational ranges. A torsion bar suspension allows for the necessary off-road capability and the hull is amphibious as in the original MT-LB, treading water at a 3-mile-per-hour-clip. Its crew numbers three - commander, driver, and gunner and armor protection is only against small arms fire, measuring 7mm thick. Primary armament is its four-shot 9M333 missile launcher which sits atop the hull on a trainable mount. The launchers are grouped as two pairs of launchers in a side-by-side format, the pairing separated by the radar array at center. The mounting hardware features full traversal and elevation controls. The launcher can also fire the older missiles of the Streal-1 family.
The original missile was the 9M31M of 1971 which used an impact and proximity fuse. This was followed by the 9M37 of 1976 and its proximity and impact fuse. Then came the 9M37M of 1981 and the 9M333 of 1989 - the latter introducing an eight-ray laser proximity and impact fuse. Maximum range has been progressively increased over the lifespan of the missile's evolution while minimum intercept altitudes have been steadily increased.
Over the decades, the Strela-10 system has been continually improved to help expand its battlefield usefulness. This has produced the Strela-10M, Strela,10M2, and Strela-10M3 marks. Its combat service has ranged from the Angolan War (1975-2002) and Operation Desert Storm (1991) to the Kosovo War (1998-1999) and others though with mixed results.
