    complex tank weapons 9K112 Cobra guided weapons 9K112" Kobra "is designed to ensure the effective conduct of cannon fire guided missiles against tanks and other armored enemy targets moving at speeds up to 75km/chas, as well as for shooting small targets (bunker, bunker), with locations and on the move, at speeds up to 30km/chas carrier, at distances of up to 4000m, with the line of sight through the goal rangefinder sight.

    Besides the main purpose complex 9K112 has the ability to fire on helicopters at ranges up to 4000m, in the presence of targeting at a distance of not less than 5000 m, the speed of the helicopter should not exceed 300km/chas and altitude - 500m.

    Head developer complex "Cobra" - CB "Tochmash" (KBTM Moscow).

    Testing of

    9K112 "Cobra" held in 1975 at the site 447 (converted T-64A) equipped with a quantum sight-rangefinder 1G21, missile complex "Cobra" with a missile 9M112. The rocket is produced from regular gun 2A46. After successful tests in 1976 modernized tank under the T-64B with the missile system 9K112-1, including a guided missile 9M112, are brought into service. After two years on arms supplied T-80B gas turbine engine development KB Leningrad Kirov Plant, equipped with missile system 9K112-1 (rocket 9M112M). Later complex "Cobra" were equipped with basic tanks T-64BV and T-80BV and some other samples experienced or limited-edition cars: 219RD object, the object 487 to 219A, etc.

    since 1976 until the present time, the domestic T-64B, T-80B, etc. take precedence over the main foreign models, they are the only carrier in the world guided weapons used in regular guns. This gives the advantage of our tanks in the fight against the enemy tanks at long ranges, where to apply the cumulative and piercing projectiles ineffective or impractical.

    currently complex 9K112 "Kobra", although it continues to remain in service with Russian aircraft obsolete. In the eighties KBTM were upgraded 9K112 complex under the name "Agon" with the use of a new missile 9M128. The results of the work are given the opportunity homogeneous armor penetration up to 650mm thick. However, by the time of completion of the development in 1985 has been taken into service complexes "Svir" and "Reflex" with guided missiles on a laser beam, so that all newly manufactured tanks family of T-80 equipped with these complexes.

    the west range was designated AT-8 "Songster" .

    Composition

    complex tank weapons 9K112 Cobra The complex guided weapons 9K112-1 includes the following elements:

    guided missile 9M112, 9M112M, 9M112M2, 9M124 (see 9M112M2/9M124 ATGM);

    block control circuits 9VZ87;

    Tank 9S461 control equipment;

    IN-900 converter.

    complex operatively associated with fire control system 1AZZ and has a semi-automatic control system shell using a modulated light source on the projectile and radio command link. 9S461 control equipment has five lettered frequencies and two code control signal. Feedback projectile with control equipment on the tank is carried out automatically installed on board of the projectile modulated light source (emitter). To control the missile on a trajectory gunner holds the reticle on the target, and the guidance system automatically leads to her rocket. Coordinates relative to rocket sighting determined using an optical system on-board source of modulated light. Control commands are transmitted by radio beam narrowcasting.

    Based on the requirements of compatibility with standard weapons of the T-64, designed for complex "Cobra" 9M112 missile is manufactured in two blocks - head 9M43 and hardware 9B447, made in the size of the projectile and charge conventional ballistic ammunition and can be located anywhere tray mechanized boeukladki autoloader. When chambering rocket 125 mm smoothbore gun - launcher 2A46-2 (2A46M) both components are automatically joined, and in this form 9M112 missile leaves the barrel. In order to increase the reliability of designers sought to exclude the possibility dock electrical networks, which concentrated in the tail block all the elements on-board equipment - radio radio command line control units and controls. This determines the layout of the rocket normal aerodynamic scheme.

    Console four aerodynamic control surfaces are disclosed after the rocket gun barrel. Block placed on the tail and arched rectangular wings in transport position close to the body and disclosures missiles after launch with a special device. And the plane of the wings of aerodynamic control surfaces are shifted from each other by 45 °. At the tail end of the light source placed antenna and radio command equipment.

    desire to provide the desired length of the head assembly to determine the layout of four oblique nozzles of the solid propellant in "flush" position in front of the combustion chamber. The nozzles are arranged in the same planes as the aerodynamic control surfaces. Hard overall placement constraints in the previously created tank autoloader is not allowed to apply for optimum supersonic missiles pointed contours - contour ogival nose of the rocket begins with the development of a spherical blunting.

    complex allows the simultaneous firing guided missiles as part of a company of tanks for closely spaced targets, including two tanks on one goal at the interval between firing tanks at the front of at least 30 meters and work on different radio links lettered frequencies and codes. There are three modes of missile guidance:

    In the main mode rocket launch is carried out at an angle of elevation tank guns 3 °, which virtually eliminates the formation of a dust cloud covering the target. After the capture of tracking of missiles at a distance of up to 100m from the firing tank begins its output to the line of sight, completes up to 900m. Boosters are 9-10s, then controlled flight continues to 17c when the radiation tank equipment is automatically terminated. Range of angles vertical guidance for this mode of fire is from minus 7 ° to 11 ° and list up to 15 °.

    The second mode (shooting in excess) is used for shooting over the dusty ground. On the main part of the trajectory the rocket flies in excess of the line of sight over the target for 3 ... 5m. Output on the trajectory carried out aiming at the final leg of the flight for 1.5 ... 2s to hit. This mode is used for night shooting - illumination of the rocket does not interfere with the gunner to keep the crosshair on target. When shooting in this mode, the gunner must first measure distance to the target.

    third (standby) mode provides a start at a low elevation angle - less than 1 ° and is used to engage targets, suddenly appearing in the near field, at a distance less than 1km. In this mode, the missile is lowered to the line of sight flight through 80-100 meters.
