The Tor-M1 is the successor to the Osa (NATO: SA-8 Gecko) surface-to-air missile (SAM) system. The 9K331 Tor [SA-15 GAUNTLET land-based, SA-N-9 naval version] low-to-medium altitude SAM system is capable of engaging not only aircraft and helicopters but also RPVs, precision-guided weapons and various types of guided missiles.
The principal advantages of Tor-M1 is its ability to simultaneously destroy two targets in any weather or at any time of day and night; the use of both the powerful and jamming-resistant radar with electronic beam control and vertically launched missiles able to maintain high speed and manoeuvrability inside an entire engagement envelope; the high degree of automation of combat operation provided by the electronic equipment suite. Tor detects targets at a distance of 25 kilometers and kills them at a distance of 12 kilometers. In combating manned aviation, Tor is thrice and 1.5 times more efficient than foreign systems of the same class - France's Crotale and Britain's Rapier, respectively.
The HQ-17 is a copy of Tor-M1, that China will use it to replace the aging HQ-61 SAMs, will enter service around the year 2005.
Although it is an autonomous system it can be interfaced into an integrated air defense network. SA-15b is designed to be a completely autonomous air defense system (at division level), capable of surveillance, command and control, missile launch and guidance functions from a single vehicle. The basic combat formation is the firing battery consisting of four TLARs and the Rangir battery command post. The TLAR carries eight ready missiles stored in two containers holding four missiles each. The SA-15b has the capability to automatically track and destroy 2 targets simultaneously in any weather and at any time of the day.
The single stage solid propellant missile has a maximum speed of 850 m/s and is fitted with a 15 kg HE-fragmentation warhead detonated by a proximity fusing system. The missile is approximately 3.5 meters long with a diameter of 0.735 meters and a launch weight 170 kilograms. The cold launch ejection system propels the missile upwards to a height of 18-20 meters, whereupon thruster jets ignite and turn the weapon to the target bearing. The main sustainer rocket motor then ignites and the missile is command guided to the intercept point where the proximity fuse is triggered.
Effective range limits are from 1500 to 12000 m with target altitude limits being between 10 and 6000 m. The maximum maneuvering load factor limit on the weapon is 30 g.
The missile launcher consists of a box container extending down below the level of the hull top, holding two groups of four ready to fire missiles in the vertical position. Each missile is in a maintenance-free factory-sealed container-launcher box. The system is reloaded by a dedicated transportation/loader vehicle.
The 3D pulse Doppler electronically beam steered E/F-band surveillance radar provides range, azimuth, elevation and automatic threat evaluation data on up to 48 targets for the digital fire control computer processing system. Automatic track initiation can be performed on the 10 most dangerous targets, which are categorized and prioritized in order of threat for engagement. The operator reconfirms the highest priority target choice and tracks this target before firing the missile. The maximum radar range is stated as 25 kilometers, but the rapid five to eight second reaction time [including fire control target prioritization] suggests a somewhat greater range. The radar antenna, on top of the turret, is swung through 90º to the horizontal position for travel. Target radar surveillance is carried out on the move but the vehicle would normally come to a halt for missile launch.
The phased-array pulse Doppler G/H-band tracking radar is located at the front of the turret. This electronically steered radar is capable of simultaneously tracking two targets traveling at speeds of up to 700 km/h in all weather conditions, and countering threat ECM operations. The antenna assembly can be folded down for travel.
Mounted on the top left of this radar is a small vertical pointing antenna which serves to initially acquire the missile after launch before it is handed over to the main tracking/guidance system. On the lower right side of the tracking radar is an automatic TV tracking system with a range of 20000 m that complements the tracking radar and enables the system to operate in a heavy ECM environment.
The Tor is not amphibious although it is airportable. An NBC system is fitted as standard as is a built-in training system. The chassis of the vehicle is almost identical to that used for the 2S6 self-propelled hybrid air defense system and is based on the GM-569 tracked vehicle. The three man crew consists of the vehicle commander, system operator and vehicle driver, seated at the front of the vehicle with the large box-like unmanned turret in the center and the engine compartment at the rear. This arrangement is similar to that of the Kub (SA-6) and Shilka (ZSU-23-4) vehicles. The vehicle suspension consists of six dual rubber tired roadwheels with the idler at the front, drive sprocket at the rear and three return rollers.
An auxiliary gas turbine powers a 75 kW generator, allowing the main diesel engine to be shut down when the system is deployed to conserve fuel.
The Russian company Antei which produces anti-aircraft missile systems has developed a new efficient system Tor M1. A number of countries have precision weapons and a reliable shield is necessary against these weapons. The new Russian anti-aircraft missile system Tor is such a shield. The system consists of a special vehicle and two radars to detect targets and to accompany flying targets and missiles, a computer, and equipment for launch and navigation. The missile unit is a transportation and launch container with four missiles. A anti-aircraft guided missile is a one-stage missile with a solid fuel engine. The system is operated by 3 or 4 people. The Tor system ensures reliable protection for government, industrial and military sites and ground troops from all types of missiles, unpiloted aircraft, aircraft bombs, aircraft and helicopters with stealth capabilities. The Tor system is the only system in the world which can detect and identify various targets. It can detect targets at a height ranging from 10 meters to 6 kilometers. The Tor system is autonomous and has short reaction time. The latest technologies of Russia's defense industry are used in it.
