Kh-28

The AS -9 Kyle was an air - to-ground missile of Soviet production. It was used for the control of ground-based radars. In GRAU index of the Russian armed forces is their name Ch- 28th

Development

Based on the U.S. experience in the Vietnam War, the development of an anti- radar missile was planned at the beginning of the 1960s in the Soviet Union. The contract was awarded to the OKB -155 -2 ( later Raduga design bureau ). Development began in 1963., The planned missile should be brought to the Yakovlev Yak -28 used. First, the Ch -28 was intended to be fitted with a solid - rocket motor. Due to the required range of 120 km, but this could not be realized with the former agents. Therefore, recourse was had to a rocket engine using liquid fuel. After a development period of ten years, the Ch- 28 was introduced in 1973 by the Soviet Air Force. The Ch -28 was the Soviet counterpart to the U.S. AGM -78.

Technology

The Ch- 28 is basically a downsized version of the Ch- 22nd It was powered by the liquid-propellant two-chamber engine R -253 -300. This developed a thrust of 80 kN. It used to fuel TG -02 and the AK -27 oxidizer. The rocket had to be filled immediately prior to use at the base with the toxic liquids. The Ch -28 came in the suppression of enemy air defenses used. Your search turned to head to the frequency of enemy radar and uses them to meet the radar position. For this, the CH -28 used the PWG - 28M seeker. This had interchangeable modules which were tuned to the frequency bands of the Nike Hercules anti-aircraft missiles, Thunderbird, Bloodhound and later Hawk.

Radar for detecting the radiation had to be equipped with special radar receiver using the aircraft. The Sukhoi Su-24, this was the built- in aircraft system Filin -H. The Sukhoi Su- 17, the externally carried gondola Metel was used. Had received the radar receiver radar beam, the plane had to fly a serpentine course at a constant height for a certain time. For the April -28- navigation system of the Ch -28 was able to determine the position of the radar system using trigonometric calculations. After the missile from a height range of 200-15,000 m could be started. From a starting altitude of 5,000 m, it had a operational range of 70 km. At a start of 1,000 m, this value was 45 km. After dropping a short unpowered phase followed. It was only at a safe distance from the aircraft ignited the rocket engine. The Ch- 28 is now flying with the help of the search head and the autopilot from the radar system. Featured during this time the radar system broadcasting one, so was the Ch -28 maintained the path taken for a maximum of 10 seconds; then she lost the target. The warhead is detonated by means of a proximity fuze. In the optimal case, this was about 5 m above the radar. The hit expectancy was around 80 % and the scattering radius (CEP ) was approximately 20 m. The 9A283 - fragmentation warhead weighed 140 kg and had an explosive proportion of 74 kg.
