    anti-missile system asroc Anti-submarine missile system" Asroc "is the U.S. Navy since 1961. It is installed on many U.S. Navy surface ships and some other countries (Brazil, Canada, Germany, Italy, Japan, Greece, Pakistan, South Korea, Spain, Turkey and Taiwan). By 1990, it was released more than 20,000 missiles of this type.

    According to Western experts Asroc anti-missile systems are one of the most effective anti-submarine warfare, due to several advantages of these complexes compared with other means of destroying enemy submarines.

    These include:

    warhead delivery (BC) to the target at high speed, which increases the probability of hitting the target as enemy submarines may take only a slight distance from the place where it is found;

    the launch of the torpedo all subsystems (if it is used as a combat unit) in the vicinity of the target, which contributes to the success of the attack;

    possibility of combat use almost any weather conditions, day and night;

    short response systems;

    possibility of conducting salvo firing, increases the probability of hitting the target.

    During the service

    complex repeatedly modernized. Refining the complex was carried out in the direction of increasing the firing range, replace the Mk44 torpedoes more effective antisubmarine torpedo Mk46, as well as the introduction of radio control rocket on a trajectory. In 1990, adopted a set of weapons ASROC-VLA c missile RUM 139.

    Composition

    anti-missile system asroc The complex consists of:

    rocket torpedoes RUR-5A (see diagram),

    launcher type MK10, Mk20, Mk26 or Mk112 (see photo 1, photo 2, photo 3, photo 4),

    naval sonar AN/SQS-23 (or AN/SQS-26),

    fire control system Mk111

    naval subsystem storage, filing and reloading.

    antiship missiles "Asroc" consists of a tandem warhead and placed behind it a solid rocket motor, connected to the adapter (intermediate compartment), which are time relay (control off and separating the engine compartment), and braking parachute. Main engine has a thrust of 5000kgs. To ensure stabilization of the missile during flight is provided with fins located in the aft of the rocket engine and the adapter. As the warhead can be used small-sized anti-submarine torpedoes, and nuclear depth charge with a charge capacity of 1 to 10kt.

    Depending on the type of warhead missiles known to the following modifications:

    "Asroc" RUR-5a Mod.3 - storpedoy Mk44;

    "Asroc" RUR-5a Mod.4 - storpedoyMk46;

    "Asroc" RUR-5a Mod.5 - nuclear depth bombs Mk17;

    RUR-5 flies on a ballistic trajectory after launch the missile is autonomous and its trajectory from the media is not corrected. The firing range is determined by the combustion of solid charge propulsion engine, which is introduced into the relay delay before starting. In the calculation of the trajectory separated main engine and warhead with the adapter continues its flight to the target. When used as a torpedo warhead Braking Mk44 warhead on this part of the trajectory produced braking parachute diameter of 1.8 m directly in front of the adapter is removed and immersion warhead enters the water with a parachute separated, and when used as a torpedo warhead launched its engine and deep bomb explodes at a given depth. After reaching the desired depth torpedo searches goal. If the purpose of the first round is not detected, it continues to search across multiple levels of depth, plunging to a predetermined schedule. After detection of the target torpedo is a rapprochement with her. Limited speed and range of the Mk44 torpedoes allow its use against submarines, going at a speed of not more than 24 knots.

    anti-missile system asroc

    Widespread complex ASROC ships of various classes contributed greatly to a successful design launchers Mk112, manufactured in the U.S. and in the UK. Ship ASROC launcher complex weighing 22 t consists of four dual cassettes, each of which holds 2 rocket. Installation can be rotated in the horizontal plane for 350 °, and each cassette is induced by the elevation angle of -3 to 85 °. It can fire a single rocket and volley in any combination from 2 to 8 rockets in cassettes on sliding rails in constant combat readiness. Opening sashes cassettes and extension rails into the firing position is made for 30 seconds before the missile launch. In the stowed position in cassettes set temperature is maintained to ensure a constant rate of combustion of solid fuel charge rocket engine under any climatic conditions. On ships U.S. Mk112 launcher and storage system, filing and reload missiles allocated to the starting complex Mk16, which has 9 modifications. Besides, PLUR RUR-5A can be used with PU or Mk13 Mk26. Application allowed missiles at sea up to 6 points.

    as detection and target designation used in complex naval sonar types AN/SQS35-23, -26.

    most important elements of the complex are ASROC fire control system and Mk111 naval sonar. Resolver Mk111 on data coming from the CEO, provides continuous determination of the current position based on the course and speed of ship carrier, wind speed and direction, air density, and generates raw data that is automatically entered into the launcher and missile system on board . If necessary, management of shooting is done manually with the remote control commander.
