    cruise missile airborne agm-28a / b hound dog create a cruise missile program (CR)" Hound Dog "was launched in 1956 - March 15, U.S. Air Force General Staff issued a general operational requirement 148 (GOR 148, General Operation Requirement 148) for the development of missiles "air-land", the bearer of which was to become the strategic bomber B-52 "Stratofortress". Each plane was supposed to carry two underwing KR nodes external suspension. New missiles to be used primarily for large lesions air defenses with further destruction of the main purposes of thermonuclear bombs svobodnopadayuschie high power, which is located in the bomb bay of the aircraft (it was later decided to allow the use of missiles and for the destruction of the main objectives directly). To improve the efficiency assumed two types of application launch - altitude flight for longer range at supersonic speeds and flight at short range at low altitude subsonic. The project was designed as a so-called. "Weapon system» - WS-131B.

    After reviewing the options August 23, 1957 U.S. Air Force General Staff announced that the results of the contest won by the corporation "North American Aviation", named prime contractor program. Development Corporation entrusted power plant "Pratt & Whitney", and astroinertial management system - the company "Kollsman". Warhead traditionally developed the Atomic Energy Commission (Atomic Energy Commission). In October 1957, the new missile was assigned the designation GAM-77. Work moved quickly - April 23, 1959 above the polygon Eglin Air Base (Fla.) with a B-52G aircraft 4135 th Strategic Wing was held the first prototype of a new missile launch. The first flight with the full use of the control system was carried out in the same place October 30, 1959. December 21, 1959 in Downey (Calif.) was collected first production GAM-77 missile "Hound Dog".

    29 February 1960 on the landfill airbase Patrick (FL) on board the B-52G was made the first rocket launch "Hound Dog". By the end of 1960 in the arsenals of the NAO was already 54 missiles, although for combat duty, they were not used. All 1960 specially selected crews to develop methods of application of new missiles. Then it was decided to expand the list of modifications of aircraft B-52 suitable for use GAM-77 missiles - if originally intended for application modifications planes G and H (see photo), by the end of 1962 under the new weapons were quickly refitted and modified C , D, E and F (a part of the aircraft).

    cruise missile airborne agm-28a / b hound dog

    August 25, 1961, the first rocket "Hound Dog" was admitted to the Air Force combat units (4126 th Strategic Wing, Beale AFB, pcs. California, equipped with B-52G). By this time, was already developed improved version missiles (GAM-77A), which features an advanced control system - a new path has been added celestial radio altimeter. Sealing arrangement GAM-77A allowed to increase the amount of fuel on board and thus range. Modified control system to keep former accuracy at extended range has improved the effectiveness of missiles at low altitudes. The first flight of an advanced rocket on May 19, 1961 and in the parade of the rocket started to arrive in September of the same year. By the end of 1961 there were already stockpiled CAA 230 missiles for both modifications.

    January 9, 1962 over the territory of the Atlantic missile test range from aboard B-52G was held the first combat training missile launch "Hound Dog" (4126 th Strategic Wing, Beale AFB, CA). Missile flew 1,125 miles and hit a designated area of the ocean. Operation was the name "Jetblack". January 17 bombers B-52G (4038-s strategic wing airbase Dau, New Hampshire) first flew on combat duty with rockets "Hound Dog" in the normal equipment. By July 1962. GAM-77 missiles were armed with 23 squadrons of SAH. By year end, there were already in the arsenals of both modifications 547 missiles. Data that the GAM-77 missiles were brought to the level of GAM-77A, is not available. January 18, 1963 over the territory of the Atlantic missile test site on board the B-52 was the first time a successful launch of two missiles "Hound Dog".

    serial production of missiles "Hound Dog" was terminated on March 28, 1963. In all there were 722 missiles - 47 experienced and 675 series, of which 428 in the modification of GAM-77A. In June 1963, the program changes the notation missile modification GAM-77A were named AGM-28B, and GAM-77 - AGM-28A. By August 1963 the missiles were formally deployed on all 29 aircraft planned squadrons (15 aircraft each). The maximum number of missiles in the arsenals of the NAO reached by the end of 1963. - 593 pieces.

    Originally planned to replace

    missiles "Hound Dog", since the mid-60s the latest strategic cruise missile air-launched AGM-48 "Skybolt", but in 1962 the corresponding program was canceled and rockets "Hound Dog" were in service much longer than planned. By the early 70s was created small-sized rocket Aeroballistic SRAM, which is housed in an amount of up to 20 pieces inclusive bombers B-52 modifications and G H, as well as in the amount of 6 pieces on a light supersonic strategic bomber FB-111A "Aardvark" ;. By the end of 1972 it was decided on the gradual decommissioning of rockets "Hound Dog", the cost of maintaining combat readiness in which increased from year to year, while the number of carriers decreased (B-52 bombers modifications C and E were the end of 1972 already withdrawn from service, as well as most of the B-52F). Decreased and the number of missiles in the arsenals of cash SAC - 542 at the end of 1965, 312 in late 1968. In the future, some missiles were reopened - at the end of 1969 the number had reached 349 units, but then continued to decline - at the end of 1972 there were in the arsenals of SAH 338 missiles.

    July 24, 1973 was completed last combat training missile launch "Hound Dog", and June 30, 1975 the last missile was removed from the plane B-52 combat duty, and placed in storage. However, the final removal of missiles AGM-28 from service due to the uncertainty for the program of ALCM was abandoned, although the number has been steadily declining in the arsenals - to 249 units by the end of 1977. By 1978 it became clear that the work program ALCM are successful. As a result, it was decided to completely remove the missiles "Hound Dog" with weapons and June 15, 1978 the last missiles were removed from storage and debited from the account SAH (42nd Heavy Bomber Wing, Loring AFB, Maine).

    History missiles "Hound Dog" would be incomplete without reference to the experiments carried out using this rocket. In 1971, a modified missile AGM-28B "Hound Dog" was tested prototype follow terrain TERCOM - modified missile was designated the AGM-28C. In 1973 he passed the test and missile with passive radar homing head, designed to destroy radar. Both innovations were experienced in the series for the rocket did not. In general, the Americans managed to create quite modern by the standards of the late 50s - early 60s missile, which significantly increased survival of U.S. strategic bombers and allowed to hit a wide range of strategic targets in the Soviet Union.

    Composition

    cruise missile airborne agm-28a / b hound dog Cruise missile" Hound Dog "was an aircraft designed on a" duck "with a thin triangular wing and vertical tail odnokilevym. Missile control via pitch and roll was carried out using the four sections of the elevons, and yaw control channel - with the help of the rudder.

    In a long narrow oval fuselage housed: a control system; thermonuclear warhead, electro - and the hydraulic system; fuel tanks, auxiliary systems and consumables. The main structural materials - aluminum alloys and special steels (rocket AGM-28B actively used massosberegayuschie technology). Turbojet housed in the ventral shell streamlined. On all versions of the cruise missile used besforsazhny turbojet J52-P-3 development and production corporation "Pratt & Whitney". Air intake - cone-shaped, adjustable. THD missiles could be used as auxiliary propulsion aircraft carrier. Supply of fuel (kerosene JP-4) missiles could then be replenished from the tanks of the aircraft carrier with the help of special devices placed in the pylons of suspension. Rockets modified AGM-28B fuel capacity was increased slightly compared with the AGM-28A, as well as the increased dimensions of the fuselage and wingspan. In the forward fuselage was placed pitot. Common to all entered service modifications and KR was thermonuclear warhead W-28. Power warhead was 1.1 Mt, which was enough to destroy poorly protected area targets, as well as disruption of air defense radar systems and various electronics. Circular error probability on the maximum firing range does not exceed 1.8 km.

    management system for all modifications entered service, was developed by "Kollsman". System KS-120 mounted on a modification AGM-28A, consisted of two separate circuits - inertial (analog computer, gyroscopes, accelerometers) placed in the housing and rocket astrokontura with the telescope, which was placed in a special compartment suspension pylon. The system could serve as a support in the event of failure of the navigation system on the aircraft carrier. Rocket AGM-28B was equipped with more sophisticated control KS-140 from the same company-developer. This system was placed in astrokontur missile body. In addition, the system was supplemented radio altimeter, which permitted the use of high-speed low-altitude welcome breakthrough as one of the main applications of the CD. To reduce the likelihood of intercepting missile air defense systems in the flight program included evasive height and the rate of advance in areas of known location of enemy air defense systems. Before separating the missiles from the aircraft carrier made the procedure for entering into the control system of coordinates refined rocket launch site of the navigation system of the aircraft carrier.

    For

    missiles were provided two basic options combat use - low-altitude and high altitude. In a first embodiment, the missile AGM-28A at speeds up to 0.83 M could cover the distance of 370 km at an altitude of about 300 m Modification AGM-28B, having a perfect management system and a large supply of fuel, overcame the same distance, but on a height of about 60 m, which, according to developers, was complicate interception missile air defense. Missiles AGM-28B, focused primarily on low-altitude version of the application to have been painted in a special camouflage - a combination of green and brown colors of varying intensity in conjunction with traditional painting the bottom of the fuselage and wings in white. Multilevel version of the application was designed to cover the distance of 1,100 km (AGM-28A) or 1260 km (AGM-28B) at a speed of 2.1 m at a height of up to 16.8 km (AGM-28A) or 17.1 km (AGM-28B ). This option is considered as a major modification for missiles AGM-28A, and that caused them the appropriate choice for camouflage - the so-called. white "Fallout." In high-altitude mode of application for several kilometers to the target missile began to dive with a further defeat targets using non-detachable warhead. In order to facilitate the maximum carrier aircraft and reduce its drag after the use of missiles has also provided an opportunity to reset the underwing pylons after missile launch. Pylons, designed for missiles "Hound Dog", after removal of these missiles with weapons used for a long time to carry other types of payload, in particular, non-nuclear bombs svobodnopadayuschih (this configuration is used on planes, applied in 1991 against Iraq in the implementation of operations Desert Storm).
