    air defense missile system S-125 Pechora-2 For countries with armed Soviet S-125" Pechora "(S-125" Pechora "entered service in 1961), the Russian financial-industrial group "Defense Systems" offers a deep modernization of the complex. The project, dubbed "Pechora-2", was created in the tender for the modernization of the Egyptian S-125.

    Modernization "Pechora-1" to the level of "Pechora-2" provides for improving the characteristics of the complex, providing a successful struggle with modern means of air attack in a complex interference environment through the use of technology and the elemental base S-300PMU1. < / p>

    "Pechora-2" provides an effective fight against low-flying and small targets. Introduction anticountermeasure provides detection, tracking and attack targets under the influence of all kinds of interference. Teleopticheskaya new system allows to detect and track targets in the infrared. Doubling the number of launchers firing capabilities of the system increases. Installation of fixed assets system chassis improves mobility system.

    should perform attracted KB "Kuncevo" IBC "Torch" CDB "Diamond", Moscow Radio Engineering Plant, SUE "CB special mechanical engineering" and a number of other Russian and Belarusian organizations.

    Composition

    air defense missile system S-125 Pechora-2 The system includes the following major funds.

    radar detection "Casta-2E2";

    one or two radar tracking and guidance systems;

    control cabin UNK (UNK-M);

    up to eight launchers with two missiles each;

    power tools and hardware.

    The launch

    - reclining, with launcher, suggestive in elevation and azimuth. Flight control and missile guidance to the target is carried out by radio, coming from the ground radar homing warhead and undermining team from radiozryvatelya when approaching the target to the required distance from the station or guidance.

    Modernization source of C-125 to the level of "Pechora-2" provides:

    Creating a new self-propelled launcher 5P73-2M on a modified chassis MZKT-6525 all terrain 6x6.

    Replace the following complex analog equipment to digital:

    O device positioning (CRM);

    O devices generate control commands (UCMJ);

    O devices moving target indication (MTI);

    O automated trigger device (APT);

    O devices low altitudes (CF);

    O equipment training and monitoring;

    O devices demodulation interference (GSHN);

    O synchronizer.

    The introduction of new means of protection against active and passive interference.

    Introduction Autolock devices and auto-tracking purposes teleoptichesky channel TOV.

    Introduction device providing special methods crawl space.

    Modernization rocket using a new starter motor and warhead detonation of radio controlled fuses for optimal warhead given pattern fuse and fields of fragments.

    Transition from towed on truck chassis cabs.

    air defense missile system S-125 Pechora-2

    launcher 5P73-2M has six driving wheels with tires of varying pressure. Powertrain - V-shaped eight diesel engine JAMZ-238D capacity of 330 liters. s. Tyre pressure regulated switch installed in the cabin. The launcher has a built-in power supply and minimal deployment unprepared in engineering terms starting position. Artchasti used for the manufacture of standard PU towed 5P73 without two extreme guides. PU propelled transported in a loaded condition, with two missiles, which greatly simplifies its preparations for combat work. PU communication with the control cabin can be obtained through the wireline or radio communication telecode. Modernization PU also provides its replacement electrical transition to a modern element base.

    The composition

    start battery introduces a new freight-loading machine PR-14-2M, equipped with hydraulic manipulator to perform charging and discharging crane way that fully satisfies the conditions of work on an unprepared area (see photo).

    When modernizing are seized 44 blocks and 6 equipment cabinets from the cockpit UNK (UNK-M) and the newly introduced two cabinets with digital equipment UK360, UK370. The composition of individual SPTA introduced nodes and elements that support the operation of newly introduced equipment. Supplied with the equipment spare parts is 50% of the equipment. Introduction of highly reliable equipment on modern technological and hardware components increases the reliability and durability of the complex.

    NEW

    ability to conduct combat operation and maintenance of the

    Modernization comprises administering automation mode capture target, inferring information about the parameters of target motion and the boundaries of the affected area on the screen workplace (PM) operator guidance that simplifies the calculation algorithm of the combat and reduce the dead time of the complex, on the operator's screen is displayed prompting "form" of the missile guidance station, containing the following information

    O current target azimuth (beta) degrees;

    O current elevation target (epsilon) in degrees;

    O slant range to the target (D) in km up to 0.1 km;

    O target height (H) in km up to 0.1 km;

    O target speed (V) in m / s up to 1 m / s;

    O target parameters (P) in km up to 0.1km.

    O The display special icons displayed as the affected area (slant range):

    § far edge of the affected area;

    § range of the engagement;

    § meeting point at the time of the missile launch;

    § guaranteed affected area.

    After missile launch in "Formulary" in situ information on elevation information appears to reject the missiles from the appointed path, and at the point where fixed miss value in meters.

    Provides increase in the affected areas and the probability of target hitting the target mode of the station without interference and under the influence of intense interference by improving the accuracy of target tracking, optimization, signal processing, reducing errors and eliminating fluctuation drifts "zeros". Complex increases immunity against various types of passive and active interference, as well as the underlying surface by the application of new methods of protecting against interference and signal processing techniques.

    The introduction of the navigation system and communication is ensured telecode targeting automated reception from any external sources of radar data;

    Employment opportunities for using complex teleopticheskogo viewfinder due to the introduction of equipment and Autolock autotracking purpose and high accuracy to determine its origin in this mode.

    Provides the ability warning of goals by introducing an acoustic indication purpose.

    Provides the ability to support the goal of sustained coordinates in case in case of temporary loss of information in the radar and teleopticheskom maintenance mode.

    Introduction of digital simulator provides simulation of complex air situation, different options plaque, various types and methods of radio interference that can improve the quality of preparation and training of combat crews complex.

    Introduction of self-control equipment n autosearch faults in the newly introduced equipment, the introduction of new types of replacement parts facilitates the work of calculations to verify the equipment and training to combat work, reducing the time and troubleshooting.

    Introduction of a highly stable equipment that has a small number of adjustable parameters, the removal of a significant amount of analog equipment allows 2-2.5 times and reduce the amount of time on routine maintenance. This simplifies the work station attendants. Power station with the new apparatus are reduced by 30%.

    Introduction of digital hardware trigger device reduces the initial data preparation, improves the accuracy of calculations borders affected areas.
