FAB 9000 High Explosive Bomb

High-explosive high-explosive bombs adopted in the late 1940s - early 1950s, were intended primarily for action on large sea targets for the second — on large stationary land targets. The largest among them is FAB-9000M50 and more advanced FAB-9000M54: its total weight is more than 9 tons and it is equipped with 4297 kg of trotyl. The bomb was intended to defeat military-industrial structures and factory buildings, ships parked. It is used when bombing from altitudes up to 16000 m with a flight speed of up to 1200 km / h (the aerial bomb tested to an altitude of 12500 m with an airplane’s flight speed of 910 km / h) ...

Its carriers were Tu-95, TU-16, TU-22, 3M and M4 bombers. From the currently available only Tu-95MS and Tu-160 can theoretically carry such aerial bombs, but practically not. The Tu-95MS is called a platform, according to its instructions, and can only use cruise missiles suspended on an internal suspension. For other purposes, it is not intended. The Tu-160 can carry all types of bombs, but it is a strategic bomber. Thus, the Tu-95 and Tu-160 are adapted for rockets, and there are no carriers left in this formation.

Heavy bombs have a definite shelf life. Recycling them is quite a difficult problem. Most often they were bombed just because the end of their fitness was coming. It was easier to use it at the test range than to destroy it by other means. Many warehouses got rid of the old type of bombs thanks to Chechnya and Afgan. Even expired bombs went off, which they otherwise simply did not know what to do with them.

In Afghanistan, the effectiveness of high-altitude bombing was low. One of the reasons for this was the inappropriate nature of the ammunition used. The heavy mines that shook the ground did not achieve the result: the few barriers identified by the intelligence did not linger in one place, leaving the strikes in time. The 9000 kg bombs themselves did not at all correspond to the tasks of fighting manpower. Even with the bombing of "enemy villages", which had completely swept away houses and duvalis, the real effect was small. The power of impressive-looking bombs was wasted: the lethal radius of the FAB-9000 shock wave remained within 57 m. The enemy received 225 meters around the disabling contusions with nose and ear bleeding, a result that was inferior to a series of front-caliber bombs that were dropped from attack aircraft.

Describing qualitative changes, an analytical note from the Directorate of Combat Training of the Ground Forces in October 1984 drew attention to the appearance of objects that "the rebels are preparing for stubborn defense in engineering." The most reliable means of defeating them was aviation. However, the “pin shots” of the 40th Army Air Force, forced to act at a considerable distance from the bases, did not give due success: fighters and attack aircraft could, at best, deliver a couple of bombs to such a distance. In addition, the high-explosive power of the FAB-500 limiting for them was not enough to destroy the shelters, often cut in solid rock or filled with concrete. Some caves did not succeed in undermining even the sappers — the laid charges could not bring down the vaults, and the explosions merely “cleaned” them.

Protected targets required adequate measures of impact, and then those very large-bomber bombs proved to be suitable. The high-impact blow from above caused shaking, cracking and collapsing of the stone that had collapsed the caves, and the landslides covered their entrances. Bombing on the slopes gave an impressive effect: hundreds of tons of stones collapsed buried the mouths of caves and approaches to them, the cornices fell to the bottom of the gorges, a few roads and trails rested against the pile of rocks, and the enemy had to spend weeks searching for workarounds. So that the explosion power was not wasted on the surface, the fuses were set to trigger with a slowdown, which allowed the bomb to go deeper and explode in the thick of the mountain. The AVU-E and AV-139E electric fuses, specifically designed for large-caliber bombs and high-altitude bombing, were commonly used.

Heavy high-explosive bombs rather intensively used in the Afghan war. So only in 3 months of 1988, the TU-16 bombers dropped 289 bombs of FAB-9000 M54. Efficiency increased when dropping bombs into small gorges, which literally formed from such power. This tactic was later used there by the US Air Force in 2001-02. B-1B and B-52 bombers, using the accuracy of their PrNK, laid bombs weighing 9980 kg in small gorges with the same effect.
