"Bunker Destroyer": What is known about the bomb that the US attacked underground objects in Iran
7 tons of explosives, was designed to "achieve and destroy opponents, weapons of mass damage located on well -protected objects", becoming the most difficult non -nuclear bomb in the US Air Force. At the same time, the attack on Iranian objects became the first known case of prompt use of ammunition. According to open sources, the GBU-57 corrugated anti-bomb bomb was developed by the Boeing concern in 2007.
The development of an ammunition creation and modernization program cost about $ 400-500 million, and the cost of one such bomb is estimated at about $ 3. 5 million. Aircraft is used for point destruction of underground bins. In the case of several ammunition, each subsequent bomb will penetrate the ground deeper than the previous one. Before detachment, the bomb can penetrate 60 meters underground, 16 meters into concrete and 8 meters in reinforced concrete.
In this case, the mass of the explosive AFX-757 and PBXN-114 is about 20% of the total weight of the bomb, the rest is a high-density eglin metal body, which withstands extreme voltages of deep penetration before detonation. Currently, GBU-57 is set for deployment exclusively on B-2 Spirit strategic bombers capable of carrying two units of ammunition on board. As of November 2015, at least 20 bombs were armed with the US Air Force.
Recall US President Donald Trump has declared an attack by the US Air Force on Nuclear and Military Infrastructure of Iran.
