In the Russo-Ukrainian War, the Russian army used a large number of Iskander series missiles to attack important targets in Ukraine, and received good results, and its penetration success rate was very high, making the S-300V and S-300PS missiles equipped by the Ukrainian army basically no achievements. Behind the high penetration rate, there is a little-known equipment that works silently, this is the bait bomb, Iskander has long claimed the equipment, but its true appearance has not been revealed, until the recent online exposure of the picture, the Ukrainian showed a strange warhead, which makes us see his true appearance.
The Iskander ballistic missile is the result of the rebirth of the Oka ballistic missile under the leadership of the chief designer of the missile, Nebobeti Meyer. After all, the Orca missile was forced to be destroyed by the United States and the Soviet Union to sign the "INF Treaty" and made everyone depressed. So the chief division simply led a group of people to re-develop the 9K720 missile system, equipped with 9M720 missiles in 1991 in the Caspsitin range in Astrakhan Oblast on the Caspian Sea coast for the first test, in 2001 the development was completed, named Iskander (Alexander the Great Arabic name: human protector), but also developed a foreign trade Type Iskander-E, with a range of 50-280 kilometers. But this is not the russian military's most desired performance, so the designer developed the 9M723 ballistic missile on its basis, that is, to increase the range, expand the warhead, so as to develop the Russian military's own version of the Iskander-M ballistic missile, which began to be test-installed in 2005, passed the army appraisal in 2006, and officially decided to install it in 2007.
Iskandar-M (Искандер-M) ballistic missile system model 9K723, equipped with 9M723 missile, radar version of the bullet length of 7.28 meters, optical seeker version 6.86 meters, bullet diameter 0.92 meters, bullet weight 4615 kg, warhead weight 720/800 kg, range 480 km, ballistic height 50 km, maximum speed of 2100 m / s, maximum acceleration of 20-30 G, the bomb using inertial guidance + GLONAS + image matching guidance / radar terminal guidance / The guidance mode of optical end guidance, accuracy (CEP) 30-70 meters, 20-30 meters (radar), 7.5 meters (optical seeker), it is rumored that it has also played 2 meters accuracy, the strike accuracy is very high, but also has a very high maneuverability ability, the head body is not separated, the ballistic trajectory is controlled by the aerodynamic rudder surface in the atmosphere throughout the flight, and the M-type ballistic trajectory can be played. The Iskander-M missile system consists of 4 launch vehicles, 4 transport loading vehicles, 1 command and control vehicle, 1 information processing vehicle, 1 technical support vehicle and 1 living support vehicle. The missile launcher uses the MZKT-7930 type 8×8 off-road truck chassis, and can also launch caliber cruise missiles, called Iskander K. The preparation time of the missile position is 16 minutes, the launch is vertical to 85 degrees and 20 seconds, the interval between the two launches is 60 seconds, the launch time of the preset position is 4 minutes, the life of the position is 3 years, and the life of the warehouse is 10 years. The Russo-Ukrainian war was simply a show of iskander-M missiles, and its huge charge, strike accuracy and penetration capabilities were all impressive.
We know that ballistic missiles in modern three-dimensional warfare has a pivotal position, the size of their penetration capabilities are directly related to the exertion of their power, in order to maximize the penetration capabilities, it is necessary to equip the missiles with as many countermeasures as possible to increase the difficulty of identification of interceptor missiles, including both the means of maneuvering to change orbits, including stealth, diversion, and launching confrontation bait, etc., but these are above the medium-range missile will be equipped, Iskander is the first crab-eating short-range ballistic missile. The decoy bomb found in Ukraine has the words 9B899 on the physical object, and the equipment has appeared on the procurement list of the General Directorate of Rocket Artillery Equipment (GRAU) of the Russian Ministry of Defense, which is said to have been developed by the Central Radio Technology Institute of Russia and the Stavropol "Signal" Radio Plant around 2008-2010, which we tentatively call the 9B899 bait bomb.
The bait itself is relatively small and lightweight, so even if it is dropped by the projectile, it will not change the stability of the projectile. To achieve the purpose of covering the target, it must have the same state of motion as the target, and the ICBM can use a similar size of heavy bait to maintain a trajectory similar to the warhead, but the short-range ballistic missile does not have this space, so it will choose a small decoy bomb, which has very strict requirements for the diameter of the projectile. So we saw iskandel-M's 9B899 bait bomb this time using a tapered head, cylindrical body, only about 40 cm long, the diameter may be about 10 cm, and did not install a folding tail, but adopted a tail skirt layout with multiple radial small tails attached, this shape structure is compact and simple, high reliability, easy to load, but because of its large bottom area, the bottom resistance has a larger increase, friction resistance is larger, Therefore, this bait will not follow the missile for too long after it is released, and it is a hammer deal.
So where was the 9B899 decoy bomb installed in Iskander-M? The Russians were very chicken and thief arranged them in 6 circular launch tubes around the engine vents at the tail of the missile. After all, the side of the projectile side opening also has to have a moving mechanism to maintain the strength, which is useless dead weight, but it is installed in the tail so push out or gunpowder rush out, the missile flight end engine has long been not working is not afraid of ablation, due to the special projectile design, the bullet is likely to have the same ballistic characteristics as the mother bomb, flying out can also maintain a similar flight trajectory with the missile. That is to say, once the missile detects the locking of the enemy's air defense missile, or whether it is intercepted or not, it is programmed and released regularly, and the direct 6 decoy bombs are thrown out, and the enemy radar operator must be very depressed, which will inevitably improve the penetration capability of the missile. It is worth mentioning that the foreign trade version of Iskander-E is not designed.
Ballistic missile on-board bait is generally divided into active and passive two types, passive bait is generally equipped with angular reflectors in the body of the decoy to achieve the same radar reflection signal as the warhead, or by inflating and so on to achieve similar appearance, consume interceptor shells, or use foil strips to drown the warhead signal. The active bait is divided into noise bait and deceptive bait, and the noise bait must be equipped with a bomb jammer with a strong radiation power, but this cannot be coordinated with the small size, and the power will lose its effect if it is not enough. In contrast, the deceptive active radar decoy can concentrate the interference radio frequency energy into the radar reception bandwidth, produce a radar reflective surface that is very close to the real target, and deceive the enemy radar through information such as distance, angle, phase, speed and acceleration, so that the radar will identify it as the target of attack, and the most will also produce a large number of false tracks, thereby greatly consuming the defender's missile and opening the way for the real warhead. So what kind of is Iskander-M's decoy bomb? Judging from the picture, the 9B899 decoy shell has a large number of components inside after the body is opened, so it should belong to the active deceptive bait, and its tail has ablation marks, obviously the tail of this bait may also emit an infrared heat signal to deal with the attack of the enemy infrared seeker missile. If necessary, Iskander-M can also completely change several passive baits.
A decoy developed during the Soviet period
The reason why Russia uses the 9B899 decoy bomb is to improve the success rate of penetration, while responding to the possible interception of Ukrainian S-300V and S-300PS air defense missiles. Although this has achieved good combat results, it will also make this highly classified munition fall into the hands of Western intelligence agencies in its entirety, thereby reducing the probability of Iskander's penetration in the face of Western air defense missiles. Obviously, Russia does not care, which also shows that they probably have a new generation of bait ammunition in their hands. If it weren't for the actual combat exposure, we really don't know when we would be able to see the true face of this decoy bomb!
