Antiaircraft missile system RBS-90

The combat vehicle of the complex is placed on an amphibious articulated tracked transporter BV 206s. The engine is "Mercedes-Benz" OM 603.950 diesel with an output of 136 hp. The combat vehicle is equipped with a generator, communication equipment, PS-91 detection radar, TV and thermal imaging equipment for target tracking (IK PI-917), remote launchers and missiles in transport and launch containers. The crew of the combat vehicle consists of 3 persons: the commander (who also duplicates the radar operator), the missile pointing operator and the PS-91 detection radar operator.

The missile guidance operator's workplace is equipped with a monitor (Fig. A), which displays information from the TV camera used to accompany the target in the daytime, and a thermal imaging camera - to accompany the target on thermal radiation at night. A television camera (range 8-12 μm) has a viewing angle of 3° x 4° and a thermal imaging camera - 4° x 6°. The operator's task when pointing the missile is to hold the target in a crosshairs until it is hit. Information about the target coordinates is transmitted by cable to a twin remotely operated launcher, which is placed on the ground on a tripod (Fig.B). It also hosts the missile's guidance equipment in the laser beam. When changing its position, the PU is folded and placed inside the tractor. Deployment time of the complex is about 8 minutes.

Joint combat operation of several RBS-90 systems is possible. Reception and transmission of information can be carried out both by cable and by radio line.

Three-axis impulse Doppler target detection radar PS-91 X-band (8.8-9.3GHz) has a detection range of hovering helicopters 8-10 km, aircraft - 16-20 km. The PS-91 provides simultaneous automatic tracking of 8 targets and has a built-in "own-as-user" identification system. The radar includes a simulator for operator training, which has 60 previously sewn into the memory of flight scenarios. It can accommodate 20 scenarios, which can be manually entered by the commander.

The RBS-90 complex is fully compatible with RBS-70 missiles - both Rb-70Mk.1 and the later modification Rb-70Mk.2 can be used. The latter option is the main one. The Rb-70Mk.2 missile with a shrapnel-array warhead is guided by a laser beam (0.9 μm range), has an extended field of view of the laser receiver, is equipped with a new marching engine and a more effective warhead.

The RBS-90 combat vehicle is capable of independent combat operations, but to reduce reaction time it is paired with the PS-90 ("Giraffe-75") all-around radar, which provides more accurate information.

The RBS-90 battery consists of a radar platoon with PS-90 ("Giraffe-75") detection radar and two fire platoons, each of which has 3 combat vehicles. The three-axis PS-90 radar operates in C-band (5.4-5.9 GHz), has a detection range of up to 50 km and can accompany up to 20 targets simultaneously. The PS-90 radar is placed on the chassis of the Tgb 45 cross-country vehicle, can be removed from the chassis and placed on the ground if necessary. The radar antenna can be raised to a height of up to 20m using a hydraulic mast. Gross weight of the PS-90 radar together with the control cabin and chassis is 16160 kg. Crew - 4 people, deployment time - no more than 5 minutes.

The target traces are displayed on the Moving Target Indicator (MTI) (Fig.B), and detection of hovering helicopters is performed automatically.
