The latest variant of TOR-M2 features improved fire control radar coverage, and four guidance channels, allowing up to four missiles to be guided at any one time. The Tor-M2E also offers the option of a wheeled chassis, as well as a new digital computer system and all weather optical tracking system. The TOR-M2 / M2E is designed to attack aircraft, helicopters, aerodynamic UAVs, guided missiles and other components of high precision weapons flying at medium, low and extremely low altitudes in adverse air and jamming environment. The Tor-M2 missile system can be mounted on wheeled or tracked chassis. The Tor-M2 doubles the number of targets that can be engaged simultaneously by a single combat vehicle to four.There are several modifications of the TOR-M1 system, such as the TOR-M1T (wheeled chassis mounted systems) and a stationary version.– 9K330 “Tor”: with the 9M330 missile, minimum range 2 km (1.2 mi), introduced in 1986– 9K331 “Tor-M”: with the 9M331 missile, minimum range 1.5 km (0.9 mi), introduced in 1991, with greatly improved missile accuracy and the ability to engage two targets simultaneously– 9K331M “Tor-M1”, “Tor-M1T”: with the 9M331 missile, minimum range 1.5 km (0.9 mi)– 9K332 “Tor-M2”, “Tor-MTA”, “Tor-MTB”, “Tor-MTS”: with the 9M331 missile and a new surveillance radar, minimum range 1 km (0.6 mi)– TOR-M2E: Export version, with a 9А331ÐœE tracked chassis mounting two 9M334 missile modules with four 9Ðœ9331 missiles.– TOR-M2K: with a wheeled 9А331МК chassis developed by the Belarusian company «MZKT» mounting two 9M334 missile modules, each with four 9Ðœ9331 missiles.– TOR-M2KM: modular design (towed variant weight reduced to 15 tons), to accommodate various types of chassis. 9А331МК-1 TELAR mounting two 9M334 missile modules with four 9M9331 missiles.
