    anti-radiation Kh-25MP (x 25mpu) In 1978, the decree of the Council of Ministers of the USSR on a modular series of tactical missiles" air-ground "with a single engine, warhead system stabilization but different guidance systems. Development of the complex was commissioned CB "Star".

    idea was born out of experience in the development and mass production of the previous generation of guided missile weapons team created the design bureau. Work on the X-23 missiles, X-25 and X-27 revealed their great community for major subsystems. Therefore, the essence of the modular concept is based on identifying a group of missiles of various purpose general subsystems which, when combined, form an integral part of all missiles for a number of modular base unit, whereas mating them interchangeable modules provide a variety of types of missiles. Application modularity missiles provided a reduction in the time to develop new products, the costs of their testing, simplified adaptation of each type of weapons to various air carriers, lowers the cost of training personnel in the armed forces, facilitated maintenance of operating organizations.

    basic principles enshrined in the ideology of building modular Kh-25M, were:

    replacement pending before the three Kh-23M, X-25 and X-27PS one missile guidance systems with interchangeable;

    the possibility of forming a line units required shape missiles;

    possibility of improving this class of weapons through the use of new types of warheads and advanced guidance systems.

    Creating modular rocket was to allow:

    reduce the number of types of missiles;

    significantly reduce the cost and time to create a new guided missile weapons systems;

    reduce the cycle of mobilization deployment of a special period;

    a family of modular components of weapons systems with a sufficient degree of adaptation to the dynamic situation in theater;

    improve the operational reliability of weapons systems;

    simplify their operation.

    The first stage is to unify the Kh-23M, X-25 and X-27PS, and further develop new options for missile homing modules and military equipment.

    The structure includes a modular series of missiles:

    Kh-25ML - with laser homing;

    X-25MR - with radio command guidance system;

    X-25MP - with passive radar homing head.

    Launch X-25MP with passive radar homing (RGSN) is designed for high-precision radar control destruction of enemy air defense systems, including anti-radar missiles (SAM) "Hawk", "Improved Hawk", " Nike Hercules ".

    To defeat SAM type "Roland-1" and "Crotale" Kh-25MP was modernized and received index X 25MPU. Modernization was to increase the frequency range and passive RGSN to use inertial guidance system, providing the opportunity to rollover guidance and re-capture target for temporary shutdown radiation radar target. Dramatically increased firing range.

    Aircraft carrier: MiG-23BK, MiG-27M and MiG-27K and MiG-27D, Su-17M3 and Su-17M4 and Su-24M, Su-25, Yak-141, MiG-29, MiG -29K.

    In

    entered service triad bureau "Star", using embedded in X-25M modular principles proposed options X-25MT with television GOS X 25MTP with GOS for thermal destruction of heat-emitting targets X-25ms with the satellite navigation and X-25mA with shielded active homing development "Fazotron-NIIP" (30-kg head start provides a range up to 40 km).

    the west missile was designated AS-12 "Kegler".

    Composition

    anti-radiation Kh-25MP (x 25mpu) The Kh-25MP made of aerodynamic configuration" duck "with X-shaped arrangement of the wing and rudder (see projection).

    missile control system - combined. In the vertical channel targeting is carried out in two stages. On the ground - with the autopilot SUR-73, which provides movement of the rocket on a logarithmic trajectory and stabilizes the rocket pitch, and roll rate. Upon reaching the bearing angle 27 - 30 ° rocket translates into a dive and making "slide" (the high-explosive warhead kick is most effective).

    The second stage - from the radiation-purpose radar homing is performed. Depending on the emission range of radar targets are set on a rocket radar target coordinators PSRP-1VP or PSRP-2VP respectively. High-GOS were created NGO "Automation».

    Coordinator PSRP-1VP allows search radar targets with continuous emission band A and tracking sector ± 30o when the rocket on the suspension of the aircraft carrier. Maximum angular velocity tracking antenna coordinator PSRP-1VP - 6 deg / c.

    head PSRP-1VP (A-077) is intended for guidance on target with continuous emission band A and has a capture angle of 60 - 100 °, allowing pelengovat station not only on the main beam, but also on his side-lobe. < / p>

    PSRP-1VP provides:

    detection and guidance on one of the three radars in the same position, differing in operating frequencies;

    switching flight guidance when you turn off the radar targeting to another station in the same position;

    reacquisition of signal failure or changing the carrier frequency;

    priority capture radar illumination as the most dangerous;

    possibility of refocusing and start on another radar.

    Interchangeable head

    PSRP-2VP (L-015) is used to attack targets with pulsed radiation range A 'and also allows signals were selected by highlighting them of interference, and briefly remember the radar position when it is turned off, continuing to follow in this area. , Coordinator PSRP-2VP searches radar range A1 goals and tracking sector ± 30o course and from +20 o to-40o pitch when the rocket on the suspension of the aircraft carrier. Maximum angular velocity tracking antenna coordinator PSRP-2VP - 8 deg / c.

    The dual-mode engine

    PRD-276 is designed for drop-in fuels in the OKB-81 under the direction of I. Kartukova. DWP-276 with the fuel charge 81 kg had cravings start 2000 kgf and time to 11.5 seconds. Warhead F-27 is located in the nose of the glider for RGSN and aft compartment for propulsion. Charge warhead filled with metallic inclusions - steel medley. Combat effectiveness achieved by setting a contact fuze undermining warhead on target (radar antenna systems vulnerable to high explosive shock, unlike protected targets other missiles requiring destruction cumulative jet or penetrative action).
    anti-radiation Kh-25MP (x 25mpu)

    X 25MP differ from the X-25, improved aerodynamics, and a modified form of a diamond profile rudders and tail. Increasing the size and weight of the Kh-25MP compared to the base variant X-25 installation required destabilizers plane rudders. Shifting the focus forward aerodynamic missiles Destabilizers reduce its margin of stability and make the work more effective rudder. On later versions of additional warheads in the tail section was removed and acceptable alignment achieved relinking missiles. Efficiency rudders increased by lengthening the missile body spacers. Freed volumes used for equipment and utilities greater capacity, which increased launch range. Increased energy consumption Air Tank provides power servo controlled flight at 90c. Accordingly, increased storage capacity and battery ampoule.

    for transportation and storage of the Kh-25MP, a special container in which it is packaged at the factory. The container provides the necessary storage conditions rocket and protects it from moisture, shock and so on.
