    antitank missile system 9k113 Competition Self-propelled antitank system 9K113 "Competition" is designed to defeat modern bronetseley to 4km away. It is the basis of anti-tank regiment level and used in conjunction with portable complexes battalion anti-tank units.

    Complex "contest" was developed in the Instrument Design Bureau (Tula) in accordance with the Decree of the USSR Council number 30 on 4 February 1970. New ATGM originally received the name of "Oboe", was later renamed the "Competition". Constructive solutions underlying the complex essentially as spent in "Fagot" at much higher mass-dimensional characteristics of the missiles posed by the need for greater range and armor penetration start.

    Complex "contest" was adopted by the Soviet Army in January 1974. Complex "Fagot" was used in mechanized infantry battalions, and "Competition" with 9P148 combat vehicle - in motorized infantry regiments and divisions. Later on, it was developed based on LAW "Competition-M".

    In Russia

    complex consists of various modifications armed ground forces in Afghanistan, Bulgaria, Hungary, India, Jordan, Iran, North Korea, Kuwait, Libya, Nicaragua, Peru, Poland, Romania, Syria, Vietnam, Finland. Own mass production of anti-tank missiles 9M113 "Competition" deployed in Iran. License to manufacture missiles were sold to Iran in the mid 90s.

    the west range was designated AT-5 "Spandrel".

    Composition

    ATGM 9M113 (see layout scheme) is arranged on the aerodynamic configuration "duck". In order to stabilize the trajectory of the rocket to rotate in flight. Rotation rocket systems in flight is provided blades and nozzles installed at an angle of 2 ° and 9 ° respectively to the longitudinal axis of the missile. Control system - with semi-automatic transmission of commands on the wire. Semi-automatic control principle is that the operator with the departure of the missile from the container until the destruction of the target keeps crosshair grid optical sight on goal, while the projectile is automatically deducted at the line of sight. Location of the projectile is determined by infrared lamp lights.

    board control equipment consists of a coil, wireline control unit coordinator, steering drive unit and lamp lights. All equipment is located in the equipment compartment, except the steering gear unit, located at the head of the projectile. Coordinator 9B61 is a gyroscope with three degrees of freedom, which provides matching commands generated ground control equipment in the coordinate system of the starting device with a rotating coordinate system of the projectile. Steering gear unit is designed to control the projectile in flight the rate and pitch using aerodynamic rudders. It is an electromagnetic mechanism with rotating anchors on which you installed the aerodynamic control surfaces. Bulb-electric light is a source of infrared radiation and the light is designed to determine the position of the projectile relative to the line of sight. It is located in the equipment compartment in the coil former wireline. 9M113 ATGM has a shaped-charge warhead 9N131, which is designed as combat compartment located between the unit and the steering gear acceleration and sustainer propulsion system and consists of a body, shaped charge and slam-detonating mechanism.

    antitank missile system 9k113 Competition

    For

    ATGM "Competition" based on BRDM-2 was created 9P148 combat vehicle (see diagram), with placed on it lifted launcher five 9M113 missiles in transport-launch containers (see photo1, photo2, photo3) . Ammunition Ammo is 20 shells or 9M113 9M111. Package guides (see photo1, photo2, photo3, photo4, photo5) can be recharged ammunition calculation in two people without departing from the armor (unlike all the complexes previously adopted in the Soviet Army). Machine loading full ammunition missiles 9M113 lasts 15 minutes. After starting the container automatically reset under fire.

    When shooting 9P148 combat vehicle operator presses the start button on the remote, and the power supply to the machine control equipment 9P148 supplied 12V DC electric igniters on-board power source, a second ground battery power supply and the powder charge rotor coordinator. When shooting with the 9P135 launcher operator pulls the trigger mechanism trigger located on the launcher, with the start in the mechanism are induced voltage pulses are fed to the electric igniters onboard power source, a second ground battery power supply and the powder charge rotor coordinator.

    Continued engagement elements at start projectile in flight and is fired from the 9P148 combat vehicle and launcher 9P135M similarly. Through 0.2 opens with the front cover of the container, and then fires electric igniter expelling propulsion. Force flame ignites the powder charge 9X180, and pressurized gas shell ejected from the container with a muzzle velocity of at least 64 m / s. At a distance of 10-15 meters from the muzzle of the container there is a start-Acceleration marshevoi installation shell. This unit is equipped with a dual-mode single-chamber solid engine jet. Dual-mode is achieved by the geometrical shape of a powder charge 9X179. After the departure of the projectile from the container light emission lamp lights enters the entrance pupil of the optical-mechanical coordinator ground control equipment, where it is converted into an electrical signal and a frequency-modulated voltage supplied to an instrumental unit. Apparatus unit automatically generates control voltage on the rate and pitch proportional to the magnitude of the linear deviation of the projectile from the sight line. In addition to the semi-automatic control system introduced by the manual correction on the final trajectory to improve shooting accuracy in terms of optical interference and disruption of automatic tracking missiles at lamp headlight. The presence of interference signals a special indicator. The minimum range is defined 9M113 projectile fuze arming range (about 75 meters).

    The package includes machine outrigger type 9P135 launcher, which, together with ammunition can be carried from the war machine and used independently. Sight and ground control equipment are the same for use in transportable and remote display options. All the facilities of the complex "Competition" and ensure the application of complex missile 9M111 "Fagot".

    Remote PU 9P135 complex "Contest" consists of:

    launcher machine 9P56M

    trigger 9P155

    hardware unit 9S474

    missile guidance device 9SH119M1.

    Design guidance

    drive 9P148 combat vehicle can fire low-speed low flying aircraft and helicopters, as well as shooting floating targets on shore in crossing water obstacles. Angle horizontal guidance 20 °. Rate to a maximum range of 2-3 rds. / Min. Calculation of 2 people fighting machine. Combat vehicle weight 7000 ± 210 kg. Complex is adapted for the landing on airborne platforms.

    Rockets type "Competition" used in the armed infantry fighting vehicles BMP-1P and BMP-2, while the ammunition was four missiles. On lighter BMD-2 and BMD-3 provides a mixed grade from one "Competition" and two "Bassoon».
