KAB-500S / KAB-500S-E

KAB-500S-E Corrected Air Bomb with Satellite Guidance System & High-Explosive Warhead in an aircraft controlled bomb equipped with satellite guidance system and high explosive warhead belongs to the aircraft high-accuracy weapons and operates by "drop-and-forget" principle and designed to engage stationary ground and sea targets like stores, moored ships by day and night and in any weather conditions.

The first mass-dimensional layout of the Russian aviation corrected bombs KAB-500S was shown to the public in 2003 during the International Air Show MAKS. KAB-500S - the Russian equivalent of JDAM - falls into the category of "smart" bombs. It is intended to destroy stationary ground and surface targets such as warehouses, silos, protected control centers, various military and industrial facilities, as well as warships and vessels berthed at the naval bases. KAB-500S will be applied in the armed modern combat aircraft at altitudes ranging from 500 m to 10 km at a speed of media 550-1100 km / h.

The basis of the guidance system KAB-500S is a dedicated 24-channel receiver-satellite navigation system (SNS) "GLONASS" / "Navstar" PSN-2001, developed by the Moscow Design Bureau "Compass." The PSN-2001 used modern radio-electronic technology and advanced algorithms for digital processing of navigation signals SNA. OJSC "MKB" Kompas "is known as the leading manufacturer in Russia Aircraft automatic radio, navigation systems, short- and medium-action, Receivers of satellite navigation systems. Among its main features of the receiver-SPE-2001 include a 24-channel parallel reception of signals at the same time, belonging to both the National Assembly or a "GLONASS" or a "Navstar".

The Russian arms manufacturers FSUE Region unveiled at the Moscow Air Show in August 2003 a series of new and improved 500 kg of KAB-500S-E guided bombs, the use of Glonass / GPS-guided, precision bombing from 5 to 10 m, the guided bombs developed about two years, was expected to serve in 2004. The company also plans to install Extended Range wing and solid rocket motors to increase the standoff range. FSUE Region company confirmed 1500 kg Series KAB-1500Kr TV-guided bombs have been exported to India last year, for "Su-30" fighter like high altitude running, bombing accuracy of 4 to 7 meters.

KAB-500S-E provides engagement of targets with well-known coordinates or if such are able to be known on the aircraft before dropping. This weapon is used as the part of aircraft armarment in the front-line-aviation - fighters, bombers and attack aircrafts such as Su - 24M, Su - 34, Su - 35, Mig - 35 etc. Particular conditions of its combat use are to be determined by the aircraft flight operation.

An equipment of global satellite navigation with a receiver of differential corrections is used in the aerial bomb as a homing system. Structurally the aerodynamic configuration of the aerial bomb is made so that a low static stability is realized in it, which allows the low-power actuators in it, which allows the low-power actuators to deflect the aerial bomb through considerable angles of attack thus providing a high maneuverability of the aerial bomb. The aerial bomb guidance system forms steep hitting trajectories, which together with the enhanced mass of the combat load, its structural parameters makes it possible to realize a high accuracy and resultant efficiency of the aerial bomb.

Famous aerial bombs with laser homing head, containing connected in series directional nozzle receiver of the reflected laser radiation and a head compartment with electronic laser unit coordinator and computing device laser homing head, the payload module with located at the bottom of the fuse and tail section, in which X-shaped fortified four stabilizer with four aerodynamic control surfaces.

The most widely spread abroad aerial bombs with laser homing head type PAVEWAY 1, PAVEWAY 2 development of the U.S. In a series of laser bombs PAVEWAY 1 includes bombs GBU 10 a/b, GBU 11 a/b, GBU 12 A/C. In a series of laser bombs PAVEWAY 2 includes bombs GBU 10 E/B, GBU 10 F/B, GBU 12 D/B, GBU 12 E/B, GBU 16 is/In The GBU 12/C.

These bombs are distinguished by their caliber, type, payload, presence (or absence) of the retractable stabilizing feathers. Caliber bombs is determined by its diameter. Bomb GBU 10 E/contains connected in series directional nozzle receiver of the reflected laser radiation and a head compartment with electronic laser unit coordinator, the compartment with the computing device, the laser focal point, control section with four installed on the X-shaped diagram aerodynamic rudders, the payload module with fuse, tail section with four installed on X-shaped diagram stabilizers with stabilizing feathers.

Aircraft bomb GBU 10 E/provides precision 6-7 m, but has several shortcomings that reduce its effectiveness and limiting the area of its discharge and conditions of use. Aircraft bomb GBU 10 E/is dropped from the carrier aircraft at goal from a narrow, limited area, initial conditions which range relative to the bombs, speed and angle of the planning match the falling bombs the target when almost ballistic flight. This is because the GBU 10 E/Into done with the use of combat troops from existing arsenals in a large number of unguided high-explosive bombs. The position of the center of mass was not optimized on the basis of conditions provide high maneuverability aircraft bombs.

One of the major drawbacks of bombs, equipped with a directional laser homing head (DBN)is a notable decrease in the accuracy of targeting in wind conditions with wind speeds more than 10-15 m/s because of the specific characteristics of the directional laser GOS, as well as the impossibility of implementation for a given GOS optimal law-guided aerial bombs, provides high accuracy and efficiency defeat its goals. Laser GOS do not provide all-weather combat use of the product.

One surprise under the wings of the Russian air group deployed in Syria was the KAB-500S satellite-guided air bomb. Several years prior to Syrian conflict it was reported that Russian Air Force had criticized that bomb due to high cost and imperfections. Throughout these years there were no reports of the use, commissioning or, at least, further tests of these bombs, so nobody expected to spot it under Su-34 bombers wings in Syria.

  • 9 October 2015. Syria bomb KAB-500S VCS RF killed 200 militants and 2 commander
  • 13 October 2015. in the province of Aleppo (Syria) blow air bombs KAB-500 Su-24M destroyed two field headquarters of the group "Islamic State".
  • 21 October 2015. near the village of Sarmin (Syria) Idlib KAB-500 bombs from the Su-34 bomber struck into the basement of one of the abandoned single buildings that destroyed the object with all its contents, the property was used as a gathering place of the leaders of the militants
