As it is known from its name, this weapon is specially designed to destroy tanks. when it comes to destroying a machine like main battle tanks, most of the Anti tank Guided missiles comes to our mind. But during a full fledged war to destroy the enemy's Tank regiments, we can not depend only on Anti-tank Guided missiles. So this work is also done with a very special type of weapon like CBU-105.OverviewCBU means Cluster Bomb unit and the CBU-105 was initially developed as the CBU -97 (Cluster bomb unit) which was an unguided air-dropped munition due to which its accuracy was not good enough.Then some modifications and improvements were made in this bomb, in which GPS system and Tail Guidance Fins were installed to improve its accuracy. Its improved version is called CBU-105.The US specifically built this bomb to be used in its fighter bomber during the Cold War, so that the Fighter Bomber can attack the Soviet Tanks while flying in the low Altitude and without getting noticed by the Radar.The B-52 heavy bomber aircraft with these bombs has the capability to destroy an entire Armored Tank division. Whereas before this bomb was developed, dozens of aircraft were required to accomplish exactly the same function by dropping a number of bombs.But this CBU-105 is so advanced that it alone can destroy 40 Tanks. This is a very unique weapon and it is so much effective because its method of operation is also very unique. When this bomb is dropped from the aircraft, the bomb reaches close to its target and releases 10 BLU-108 sub-munitions fitted inside it.The addition of the wind correction and smart guidance system made it a lethal, precise air-to-ground weapon system.Technical Specifications of CBU-105Total weight : 427 kgOverall length : 2300 mmDiameter : 400 mmNumber of submunitions : 10 BLU-108 submunitionsTechnical Specifications of BLU-108 SubmunitionTotal weight : 3.4 kgLength : 95 mmDiameter : 127 mmSensors : Dual-band IR ; LADARHow it Works ?When a CBU-105 SFW (sensor-fused weapon) is deployed, its onboard navigation system uses GPS and sensors to navigate the bomb to the nearest point the target. When the sensors determine that the waypoint has been reached, a release door is opened. 10 BLU-108 sensor-fuse sub-munitions or mini bombs fall towards the free-target.A parachute is installed on each sub-archive. The parachute opens upon reaching the specified target area. Upon reaching the specified height, the parachute is jettisoned with the help of small rockets. With properly aligning the direction of motion, the rockets add angular spin to each sub-mission. When sub-munitions begin to spin at high speeds, four hockey puck-shaped sensor-fused projectiles called skits are transmitted outward due to centrifugal force.An infrared sensor is mounted on each skeet. This locks on to a target and detonates the skeet. This explosion releases a molten copper penetrator, which is hot enough to penetrate armor. A wide shrapnel ring is also created because of the fragmentation of the skeet.In case the bomb has been dropped accidentally or if all targets have been eliminated, the skeet self-destructs on hitting the ground. This is to prevent the risk of unexploded munitions setting off explosions when friendly forces move in.ConclusionThe CBU-105 is an effective anti-armor weapon due to its wide area of coverage, all-weather utility and multiple-platform compatibility. The CBU-105 has a greater than 99.6% reliability rate and with the addition of the CBU-105, The Indian Air Force will have another powerful weapon in the area against an attacker.

No, the US doesn’t have an equivalent of a TOS system. But then, the whole US concept of payload delivery and frontline support is different, so it’s not a surprise.When the US Army or USMC encounter enemy resistance and need fire support what are they expected normally to do? Spot the enemy position and call for air support. Depending on the situation it can be a helicopter, it can be a precise missile strike or it can be an air raid by a fighter-bomber (or two).The US expect to deliver their support by air - either from aerial launch platform like an airplane or from naval platform like a missile destroyer. Then, naturally, if you want to have a thermobaric munition you’re not going to build a ground vehicle carrier and an unguided missile for it. You’re going to design a bomb or a air-to-surface missile and a surface-to-surface missile for a precise strike.And guess what? The US has exactly that - the BLU and CBU series of bombs and the AGM Hellfire surface-to-Surface missiles. The United States expects its forces to operate in the environment of aerial and naval superiority at a location far from home territory, likely in hostile territory far from friendly bases. Then why deploy a ground vehicle that is relatively slow, vulnerable, difficult to supply and deploy at a remote location in a role that an aircraft can very successfully fulfill?On the other hand the Russian Army generally expects to operate in the environment where the enemy has air superiority or at least the air is contested, there is no naval support available at all and the fighting is going on inside or close to the Russian borders, or in friendly territory where the army can have bases and repair shops (like Syria for example). So the natural solution in this case is go for a ground vehicle.So, Russia has TOS.The US military is a global military. The US military is designed in such a way as to enable the United States to strike anywhere on the planet at any time. The design decisions that went into the creation of that military force had to prioritize mobility, rapid response capability, range of operations and efficiency (the ability to “achieve more with less” because all the means have to be delivered from far away).The Russian military is a continental military. Russian military has been designed with a war near the Russian borders in mind and on a contiguous piece of land that would allow driving around without boarding a ship or a plane. As a result the design decisions that went into the creation of the Russian army prioritize hitting and staying power, anti-air defence and the ability to dish out maximum damage - the “sledgehammer punch”, because all the means are expected to be available close by.Hence the US army does not find the concept of a ground launcher very appealing, while the Russian army does.

"Cluster bombs" is a highly charged, highly loaded term that implies that you drop a bomb that explodes into packages of other bombs that spray everywhere -- the fear of course being that they leave UXO -- unexploded ordnance.What the U.S., and other militaries, use are submunition dispensers. First, I've edited the question to remove the phrase "banned weapons." Cluster munitions are only banned for the 83 states who ratified the Convention on Cluster Munitions. The three major military superpowers -- U.S.A., China, and Russia, are not signatories to this convention; thus is is not "banned" for them. The overwhelming majority of signatory states do not have any munitions production capability of their own (i.e. they cannot make their own bombs anyway and must purchase those of other states) or lack significant militaries. In fact, of the signatory states, only the U.K., France, and to a lesser extent Germany have any significant capacity in their defense industries to produce these in the first place (BAE, Matra, etc.) So suggesting that there is a "ban" on these weapons is highly misleading.Now, back to submunition dispensers.Meet the Wind Corrected Munitions Dispenser, by Lockheed Martin. This can be filled with a variety of submunitions tailored to meet the needs of a specific target. In 2003, when we were bombing Baghdad and wanted to destroy communications antennas on the Ministry of Interior building without damaging the rest of the structure, we used these loaded with steel rods (collectively, the CBU-107 Passive Attack Weapon). The WCMD reaches the target, then fires roughly 3,750 steel rods, for each weapon, at high speed into the target, destroying structure and armored targets while minimizing civilian injury and creating no explosions (other than perhaps secondaries from exploding tanks).Meet the BLU-108/B submunition dispenser, from Textron Defense Systems. When paired with the WCMD (collectively, the CBU-97 Sensor Fuzed Weapon), it is a precision guided weapon capable of destroying specific armored targets across a wide area, while leaving everything else untouched. See those 4 things that look like toilet paper rolls, or coffee cans? Those are "Skeets." Each CBU-97 contains 10 of these dispensers, which each contain 4 Skeets, for 40 total Skeets. Each BLU-108 dispenser is ejected from the weapon and slowed by parachute, then launches its Skeets in a spinning motion, so that the sensors in the Skeets cover a wide circular area. Each of the 40 Skeets scans the ground beneath it while spinning in a circle for greater coverage, and when it detects the IR signature of the target vehicle (and it can be programmed to only detect certain types), it fires an EFP -- an explosively formed penetrator, which is a basically molten hot steel or tungsten rod that blasts through the top armor (the weakest portion) of the tank, destroying it, with minimal impact to anything surrounding the target.If it detects nothing, it does nothing and will simply fall to the ground, where it can't harm anything (there are no actual bombs inside this -- the EFP is formed from the metal casing of the skeet itself). Correction: from a metal disc inside the skeet; see comment to this answer clarifying. A single strike fighter with these can destroy an entire armored battalion single handedly; a single B-52 could literally obliterate an entire armored division by itself with sufficient numbers of these.To see one in action:http://youtu.be/AfnGqtxYLpA
