    cruise missile airborne agm-86b (agm-86c / d) Cruise missile AGM-86B is designed to engage stationary, including the strong ground targets: ICBM silos, command centers, industrial and administrative centers of the enemy. Full development of the cruise missile air-launched long-range, which received the designation AGM-86A, in the framework of ALCM ("Air-Launched Cruise Missile") began in July 1973. In February 1974, the main contractor on the topic was chosen corporation "Boeing". The first launch of AGM-86A was held in March 1976, in September of the same year was promoted to launch a fully functioning control system. In January 1977 it was decided to start full-scale production of missiles AGM-86A.

    However, already in 1977 started the project JCMP ("Joint Cruise Missile Project"), in which on the basis of Raman AGM-86A was decided to develop an advanced air-launched missiles with increased range, which received the designation AGM-86B. One of the main goals of the project was also JCMP maximum unification advanced cruise missiles being developed for the needs of the Air Force and the U.S. Navy. For surface ships and submarines of the U.S. Navy by "Raytheon" developed cruise missile BGM-109A "Tomahawk". During the implementation of the program JCMP was decided to equip missiles BGM-109A and AGM-86B single system image trajectory correction terrain AN/DPW-23 corporation "McDonnell Douglas" unified and small-sized bypass jet F107-WR-100 company " ; Williams ". In addition, partial unification was carried thermonuclear warhead future KR - both missiles were equipped with modifications W-80 warhead. First run KR AGM-86B took place in August 1979.

    In 1979-1980,

    . U.S. Air Force conducted a contest, which was represented by two missiles - AGM-86B corporation "Boeing" and AGM-109 firm "Raytheon" («air» modification BGM-109A "Tomahawk"). Despite the fact that the creators of AGM-109 advanced more advanced concept of placing missiles on board the bomber B-52G, according to which the plane took on board up to 18 AGM-109 KR (12 missiles on two underwing hardpoints and 6 in the bomb bay on a rotating rocker launcher installation) against KR 12 AGM-86B on two underwing hardpoints, victory in the competition was given missile AGM-86B corporation "Boeing".

    Onboard equipment

    strategic bombers B-52G "Stratofortress", which were to become carriers AGM-86B, modified within the program OAS ("Offensive Avionics System"). Later, under the new missiles and planes began to convert B-52H. In the 1981-1990. 195 has been upgraded machines (99 G and 96 modifications modification H). First new missiles were deployed on aircraft B-52G 416 th Heavy Bomber Wing USAF SAC (Griffiss AFB, NY), the aircraft which began to alert duty with CR AGM-86B in December 1982. From 1988-1993. all B-52H bombers and received multi-position rotary vnutrifyuzelyazhnyh launcher CSRL ("Common Strategic Rotary Launcher"), which increased the ammunition one aircraft to 20 missiles (conversion from older B-52G was abandoned). In September 1991, by order of President George HW Bush all strategic bombers (including equipped ALCM) and serve them air tankers were removed from the constant combat duty. Regular flights of bombers with missiles AGM-86B in combat gear were discontinued in September 1992. Missiles were withdrawn in active reserve and listed in the "nuclear competition".

    Missiles AGM-86B and planned to equip supersonic strategic bombers "Rockwell" B-1B "Lancer", which began to be delivered to combat units SAC USAF in July 1985. 100 issued bombers were equipped with hanging nodes and could carry up to 20 AGM-86B (12 on the outside and on the inside of the suspension 8). However, the test program, launched in November 1987, for various reasons, has not been brought to an end. In 1996, after the acquisition of these aircraft the possibility of using high-precision conventional weapons, special suspension components and equipment intended for nuclear weapons were dismantled, and these machines were removed from the so-called. "Nuclear offset".

    cruise missile airborne agm-86b (agm-86c / d)

    all were released in 1715 missiles AGM-86B and in October 1986 their production was discontinued. In June of the same year, the corporation "Boeing" in the beginning of the study program CALCM ("Conventional ALCM"), aimed at creating a non-nuclear ALCM warheads. New modification received the designation AGM-86C (CALCM Block 0). In order to save money, it was decided to convert part of the existing missiles AGM-86B. When replacing a thermonuclear warhead at high-explosive fragmentation rocket mass significantly increased, which caused a significant reduction in range. The main difference between AGM-86C from its predecessor lay in the control system - a system of trajectory correction in the image of the terrain AN/DPW-23 was dismantled and instead installed a satellite navigation system GPS, which significantly increase the accuracy.

    missile AGM-86C achieved combat-ready status in January 1991, which allowed the U.S. Air Force to use it in Iraq during Operation "Desert Storm". Missiles, the official whose existence was revealed only in 1992, were developed in the framework of the program "Senior Surprise". Operation to use rockets called "Secret Squirrel". Seven strategic bombers B-52G Stratofortress from the 2nd Heavy Bomber Wing (Barksdale AFB, LA) with incomplete flew combat boot (on board was located at 39 ALCM potential place 84 missiles). Targets in Iraq was successfully released 35 rockets of 39, after which the aircraft returned to base. Flight took place without landings, with numerous in-flight refueling.

    In 1996, it adopted a new weapon modification missiles AGM-86C, which received the designation CALCM Block I. Rocket got heavier and powerful high-explosive fragmentation warhead and improved control system - receiver satellite navigation system has become a multi. All previously released missile in Block 0 variant have been brought to the level of Block I. CALCM Block I missiles were widely used during the military aggression against Yugoslavia.

    began in 1998 to develop the next modification CALCM - Block IA. In January 2001, the new missile entered service. The missile has an improved receiver satellite navigation system to provide higher accuracy and resistance to interference in memory onboard computer may have several routes ALCM approach to the target, which increases the efficiency of a missile in flight over the desert or steep terrain. All missiles CALCM converted from previously issued missiles AGM-86B. Rockets CALCM, issued before 2001 were onboard electronics Block IA level without changing an existing designations. New missiles were used during operations against Afghanistan and Iraq.

    last modification date version CALCM rocket is a missile AGM-86D (CALCM Block II), made its first flight in November 2001. CALCM Block II missile is equipped with a penetrating warhead AUP ("Advanced Unitary Penetrator"), developed "Lockheed Martin", and is designed to destroy buried and hardened targets.

    only carrier of all available modifications ALCM CALCM (as AGM-86B) - strategic bomber Boeing B-52H, is planned to keep the U.S. Air Force until 2030.

    Composition

    To reduce radar visibility on the body, wing and stabilizer has been specially treated.

    warhead strategic ALCM AGM-86B is the warhead W-80-1 (weight 123kg, length about 1m, 0.27m diameter) with the presence of a selective choice of power options - 150kt or 5kt. Warhead developed by Los Alamos National Laboratory ("Los Alamos National Laboratory"). Undermining made contact fuze. 3km radius of destruction. High accuracy and considerable power of thermonuclear warheads allow high efficiency strongly protected hit small targets. According to American experts, the probability of destruction of a protected object to withstand an overpressure of 70 kg/cm2, one ALCM is 0.85 (SLBM "Poseidon-C3" - 0.10).

    The rocket

    CALCM AGM-86C Block 0 is set high-explosive warhead weighing 900 kg. Rockets CALCM AGM-86C Block I / IA a more powerful non-nuclear high-explosive warhead weighing 1450 kg, which further reduced the range. Rocket CALCM AGM-86D is equipped with a non-nuclear penetrating warhead weighing 540 kg.

    control and guidance system ALCM AGM-86B is a combination of the following subsystems:

    inertial P-1000, developed by "Litton"

    trajectory correction system in the image of the terrain AN/DPW-23 corporation "McDonnell Douglas" type TERCOM ("Terrain Contour Matching")

    Inertial Subsystem (weight 11kg) control works on all parts of the rocket. It includes an onboard digital computer, an inertial platform and barometric altimeter. Inertial platform consists of three gyroscopes to measure angular deviations missiles and three accelerometers. The system provides a definition of space rocket with an accuracy of 800 m for 1 hour of flight. The right to secede from the ALCM carrier aircraft inertial data is updated subsystem control rocket to the coordinates of the current location and altitude. Leading role in this process, the system plays an inertial control system aircraft carrier.

    correlation subsystem TERCOM works at the middle and end portions of the flight of the rocket. It includes computers, radio altimeter, a set of reference maps of areas along the flight path of the rocket. Beamwidth altimeter 13-15 °. 4-8 GHz frequency range. Principle of operation of the subsystem TERCOM based on a comparison of the terrain specific area finding missiles with reference maps of the terrain along the route of its flight. Determination of terrain is accomplished by comparing data radio - and barometric altimeter. The first measures the height of the earth's surface, and the second - on the level of the sea. Information about a particular terrain digitally inserted into the onboard computer, which is compared with the actual data on the topography of the terrain and reference maps of areas. Computer generates signals for correcting inertial control subsystem. Stability of the subsystem and the required accuracy TERCOM determine where a cruise missile is achieved by selecting the optimum number and size of cells, the smaller their size, the better the monitored terrain, and hence the location of the missile. However, due to the limited amount of memory on-board computer and a small time of navigation adopted by the nominal size of 120 x 120 m The entire route of flight of a cruise missile over land is split into 64 district correction length of 7-8 km and a width of 0.8-2 km. Adopted quantitative characteristics of cells and areas of correction, according to U.S. experts, provide the conclusion of a cruise missile to the target, even when flying over flat terrain. Permissible error of measurement of height of the terrain for the reliable operation of the subsystem TERCOM shall be 1 m

    On rockets CALCM all modifications AN/DPW-23 system removed and replaced with a satellite navigation system GPS Corporation "Interstate Electronics", which significantly increase the accuracy. Beginning with CALCM Block I, a satellite navigation system to constantly upgrade, refine and inertial control subsystem. Accordingly grew and accuracy.

    missile AGM-86B equipped with small two-stage twin-engine turbojet F107-WR-101 firm "Williams" (see photo) with a low-pass ratio and mixed flow nozzle in both circuits. Fuel - JP-9.

    Bombers B-52H equipped with rotary launchers CSRL (see photo) and allow you to post on the board to 20 missiles AGM-86B - bombootseke 8 missiles in CSRL, and 12 missiles on two pylons under the wings. Each pylon can carry 6 KR (see photo) and attaches to the suspension assembly of aircraft B-52, located between the fuselage and the inner engine pylon. Weight is 2270 kg pylon. After starting all KR pylons can be discharged to reduce the drag of the aircraft.

    According to the requirements of the SALT-2, for the purpose of identification by means of space exploration airplane wings B-52G-KR carriers (carriers in CR were converted part of the available B-52G) was equipped with a small decorative excrescences at the root portion ("strakelets" ;). Aircraft B-52H-KR carriers like excrescences not equipped with, as all the available machines of this modification were carriers of the Kyrgyz Republic, and distinguish, in turn, B-52H from the B-52G by means of space exploration was not important works.
