Lists on the subject

KAB-500 denotes a series of precision bombs from Soviet / Russian production. KAB stands for k orrektirujemaja a wiazionnaja b omba ( Russian корректируемая авиационная бомба , course-correcting aircraft bomb ' ) and 500 stands for the weight class of the bomb. The series includes the bombs KAB-500L , KAB-500Kr , KAB-500S and KAB-500PL .

development

In 1970 GNPP Region (now Tactical Missiles Corporation ) in Moscow received an order to develop precision bombs in a weight class of 500 kg and 1500 kg. The bombs should be equipped with a laser homing head or an electro-optical guidance system. Rumor has it that search heads from Paveway , AGM-62 Walleye and GBU-8 HOBOS bombs recovered during the Vietnam War were used in the development . The in-house bomb tests were completed in June 1974. In August 1975, the state authorities completed the acceptance tests in Akhtubinsk . Series production began in 1976 and in 1979 the KAB-500L (with laser target seeker) was officially introduced to the Soviet Air Force. The KAB-500Kr version with an electro-optical seeker head was ready in early 1984. The KAB-500S version with satellite control was first presented in 2003. The initial operating capability was achieved in 2007 with the first delivery to the Russian Air Force . Originally, the Russian Air Force did not intend to mass-produce the KAB-500S.

technology

The KAB-500 can be used against a wide range of strategic and tactical targets, such as air defense , ships , bridges , transport facilities, traffic systems and bunkered systems . For this purpose, the KAB-500 has a modular structure and consists of the following parts: seeker head, warhead and steering unit. The BU-56 steering unit is located in the rear of the bomb and controls the PG-9-2 gas generator, which generates the steering impulses for the four control surfaces. In addition to the steering unit, there are different versions of all modules that can be combined with one another. The bomb has a cylindrical, elongated hull shape with a circular cross-section. There are four control surfaces at the stern. There are four stabilizing surfaces on the front third of the torso. Depending on the different search heads, there are three KAB-500 series:

KAB-500L

KAB-500L

The KAB-500L version uses Azov 27N and later 27N1 laser target seekers . These were developed by OAO Peleng . The search heads essentially correspond to the American Paveway I / II search heads. Laser target illumination is required for the KAB-500L . The laser target illuminators of the type Klen PM / PS , Kaira 24M or I-25 Schkwal are used. The target containers Sapsan-E and Damocles from the French manufacturer Thales can also be used. The bomb's laser seeker is gimbaled and automatically adjusts itself to the weapon’s velocity vector using a round box wing . The laser light reflected from the target is captured by the viewfinder. The received laser energy is focused on a sensor and processed. The control logic determines the necessary steering impulses for the four control surfaces on the rear of the bomb. The KAB-500L can be dropped from an altitude range of 1000 to 8000 m and at a speed range from 550 to 1100 km / h. The maximum operating distance is 9 km. The minimum operating distance is 3 km. The mean accuracy ( CEP ) is 3 to 7 m. The KAB-500L is 3.04 m long and weighs 370 to 525 kg, depending on the version. The fuselage diameter is 400 mm and the wingspan is 750 mm.

1 The penetration warhead is able to penetrate 10 m of soil and then 1.5 m of reinforced concrete .
2 The effective radius is almost 22 m.

KAB-500Kr

KAB-500Kr-OD

The first version of the KAB-500Kr used the Krym type electro-optical seeker head . This seeker head could only be used in daylight and the camera only enabled the fight against high-contrast targets. The improved 7TM1 Krym-M seeker head can track and hit captured targets under optimal conditions ( fire-and-forget ). After the bomb has been dropped, the data link is activated and the TV image from the seeker head is transmitted from the top of the bomb to the aircraft. This means that the target can be precisely sighted and the TV image is transmitted until the guided weapon hits the aircraft (man-in-the-loop). Course corrections can be made with a small joystick . The carrier aircraft must be equipped with an APK-8 or APK-9 data link pod to transmit the image data from the bomb seeker head. Newer models of the KAB-500Kr are equipped with a DSMAC seeker head ( terrain-contour comparison ) of the Tubus-2 type. This works on a wavelength of 0.4 to 0.95  µm and can be used at night and also against low-contrast targets. Likewise, the bomb can find and hit a target selected before dropping by itself. The seeker head is produced by OAO Impuls . The KAB-500Kr can be thrown from an altitude range of 1000 to 11,000 m and at a speed range from 550 to 1100 km / h. The maximum operating distance is 15 to 17 km. The minimum operating distance is 2 km. The mean accuracy (CEP) is 3 to 7 m. The KAB-500Kr is 3.05 m long and weighs 385 to 560 kg, depending on the version. The hull diameter is 350 mm and the wingspan is 750 mm.

KAB-500S

The KAB-500S version uses a combined INS / GPS steering system. The SPE-2001 steering system works with a 24-channel receiver for the satellite navigation systems GLONASS and GPS . Depending on availability, the steering system automatically selects one of the two satellite signals. The SPE-2001 steering system is produced by IBC Compass . The KAB-500S can be used regardless of the weather and time of day. The KAB-500S can be dropped from an altitude range of 1000 to 11,000 m and at a speed range of 550 to 1100 km / h. The bomb weighs 560 kg and is 3.00 m long. The fuselage diameter is 400 mm and the wingspan is 750 mm. The fragmentation warhead weighs 380 kg, 195 kg of which is due to the explosives . The detonator has three different modes and can be adjusted depending on the nature of the target (impact, delay or time detonator). The mean accuracy (CEP) is 5 to 10 m.

KAB-500PL

The KAB-500PL is used to combat submarines . It is similar in structure to the other KAB-500 bombs. However, there is no guided bomb fall; An active and passive working sonar is housed in the top of the bomb . This is activated as soon as the bomb hits the surface of the water. As the bomb sinks toward the ocean floor, the sonar searches for submarines. If a target is detected, the bomb steers towards the target with the help of the four control surfaces. The ignition is carried out by an impact fuse. The Ilyushin Il-38 May is known as the only operational platform .

commitment

The KAB-500 was first used on a test basis from 1988 to 1989 during the Soviet intervention in Afghanistan . After that, the KAB-500 was used in operations in Dagestan , the Chechnya War and the 2008 Caucasus conflict . The KAB-500S with satellite control was first used as part of the Russian intervention in the civil war in Syria in October 2015.
