    anti-radiation missile standard-arm anti-radar missiles "Standard-ARM" (AGM-78) is designed to defeat radio aids, especially SAM radars and anti-aircraft artillery. Its development. in 1966 beginning, the company "General Dynamics" to replace the anti-radar missiles "Shrike", which were significant drawbacks to use pre-customized GOS and the impossibility of homing in on radar stopped working. In 1968, "Standard-ARM" was adopted by the Air Force and the U.S. Navy and used airplanes F-105F, A-6A and F-4E). In addition, it equipped with the Israeli armed forces and the Republic of Korea.

    Composition

    anti-radiation missile standard-arm Launch "Standard-ARM" developed based on SAM "Standard-1" RIM-66A and has the same aerodynamic and structural schemes. The missile is equipped with a dual-mode solid engine Mk.27 mod.4 weighing 360kg. Combustible mixture of polybutadiene and polyurethane oxidizer - ammonium perchlorate.

    It uses the method of passive radar. In this regard, several options have been created broadband passive radar homing with different operating frequency range. In seeker have equipment that allows to memorize the target coordinates, so its guidance can continue even after turning off the radar radiation. Specially designed radio-fairings (CW-1106 / D) provide the transmission of signals from virtually all radar stations within the operating range of the GOS. They are made of material with crystalline structure. Application fairings with different bandwidth allows for a certain selection of radar signals. The missile is equipped with a powerful high-explosive fragmentation warhead (weight about 150 kg), which is produced by undermining the height of 15 - 20 m above the target. The radius of the expansion of its fragments (cubic shape with an edge length of 10 mm) is about 600 m This technique ensures destruction of warheads up to 150 m, and manpower - to 500 m During surface explosion crater formed a diameter of about 5 m intermediate compartment missiles located near the warhead, set the signal charge, which is formed after the explosion of smoke cloud, which is a benchmark for the implementation of other aircraft bombing.

    anti-radiation missile standard-arm The following modifications were made missiles "Standard-ARM": AGM-78A (vers. 1-3), AGM-78B (vers. 1-3), AGM-78C (mod. 03.01) and AGM-78D (Mod. 1 and 2).

    They have some design features and different operating frequency bands of the GOS. So, on a rocket AGM-78B fairing installed mod.1 CW-1071 (plastic material), which transmits radar signals rather broad spectrum, and AGM-78B fairing mod.2 used CW-1070D (ceramic material), which provides only defeat special radar.

    tests and operation

    anti-radar missiles (PRR) "Standard-ARM" were used in the Vietnam War, and during Israel's military action against the Arab countries.

    In 1976, production of missiles, "Standard-ARM" was discontinued. Total Air Force and the U.S. Navy was delivered about 3,000 rockets. Termination of missile production was associated with a large value of the rocket - almost three times higher than that of the rocket "Shrike".

    Other disadvantages include a relatively small missile flight speed, allowing the enemy to take kontmery srvyu attack, and the lack of homing, providing overlap sufficiently wide range of frequencies.
