US Upgrades Anti-Bunker Bombs in Response to Iran's Enrichment

58
The U.S. Air Force will continue to upgrade its existing arsenal of anti-bunker bombs, the GPU-57 MOP (Massive Ordnance Penetrator), to the latest version of the GBU-57E / B in response to Iran’s filling uranium enrichment centrifuges. It is reported The Drive.


US Upgrades Anti-Bunker Bombs in Response to Iran's Enrichment


In February last year, the US Air Force command announced the purchase of an unnamed number of GPU-57 MOP anti-bunker bombs to the existing twenty. Ammunition was ordered in two versions: in combat and inert, which can be used both for training purposes, and paired with a war bomb as a means to pre-create a crater where, thanks to satellite guidance, the combat will be dropped.

The U.S. Air Force suggests that an updated version of the GBU-57E / B bomb, equipped with a warhead accelerator, will be able to reach the Fordo nuclear facility, sheltered at an 100 meter depth under several layers of reinforced concrete.

The GBU-57 bomb or Massive Ordnance Penetrator (MOP) is an American Adjustable Anti-Bunker aviation a bomb developed by Boeing in 2007 to destroy underground bunkers. According to the claimed characteristics, it is able to penetrate into the ground to a depth of 61 meters or punch up to 19 meters of reinforced concrete and only then explode. In 2018, the fourth modernization of the bomb was carried out, as a result of which the characteristics for the destruction of difficult and deeply located targets were improved.

With the total mass of the bomb in 13,6 tons, the mass of the warhead is 2700 kilograms. The bomb is the most powerful non-nuclear weapon in the US arsenal. The sole carrier of the GPU-57 MOP is the B-2 Spirit bomber, although B-52Н trials with anti-tank bombs were previously reported.

The US Air Force Command previously stated that GBU-57 will be used to destroy underground uranium enrichment plants in Iran and North Korean military facilities hidden deep in the rocks.

        It is rightly said, and they boasted about the capabilities of the bomb, and yet it still needs to be delivered to the place where the command bunker is supposedly buried.

        And again I am in doubt - is it really possible - to smash the shelter covered with 20 meters of reinforced concrete ?! In the same place, not fine-grained finishing mixture goes to concrete, but cement of good grades, and the reinforcement is of high quality!

      At that time the theater was not aware that the United States, after the events in Vietnam, sticks its nose only where there is no one to click on this nose. Iran has such an army that 50 thousand coffins from Vietnam seem like seeds. Americans will not climb with their "gun" on Iran. Even with the full support of their Middle Eastern mongrels.

          The IRGC should do what at this time? Corn protection? Iran is not a country where it is possible to fly in one or two times and calmly fly out.
          And therefore, it is safe to say that the Americans are trying.

            It is likely that now such a one-time disarming strike is possible. And they are just getting ready to protect themselves as much as possible from the response. Among the main events, I see Israel’s increased preparations for possible shelling and conflict on its border, + the US is preparing to quickly increase its air group in the region. The second wave, they can begin to demolish the petrochemical industry of Iran.

    Here, the military built a building for the pumping station in the port ... built in the 80s .. the building was never useful .. The businessman took it for his needs .. there is no entrance. Well, they took the pneumatic chippers and let's scratch the wall .. We cut ourselves in 2 months, periodically heating and cooling the surface .. The wall thickness is 0.3 m ... We hollowed with a hydraulic chipper ...

        The goal was precisely to punch the passage, all methods of cutting concrete are the destruction of the structure ... You can not cut a piece of concrete support? And then .. there are important types of concrete .. for example, marine, from which moorings, breakwaters are made ... There are for the construction of nuclear power plants ... I talked about marine concrete.

So good luck with their GBU to break through a multimeter rock ...

                        C'mon, I started wars only because the neighbors roamed with me as missionaries and spread their religion.
                        All is fair! The missionary came - get a vigorous loaf in the capital. All according to the precepts of Gandhi.

                    Andrey, I would agree with Alexey on this issue. Just look at the situation from the Americans' bell tower. They, most certainly, believe that they are doing a good deed both for themselves (and it is in general) and for the world. And military pilots are different. There are those who just sincerely serve for the Motherland and only, and there are those who, in addition to their personal interests, pursue: to get the very risk and thrill. And they and we. Check out the blog of the same fighter_bomber who served in Syria on the Su-34. He has a very immodest position on this issue. In short, throwing bombs into a thrill and letting go of jokes on the topic "did the target deserve an expensive ammunition or could it be cheaper" and so on, but all for the sake of an extra opportunity to fly, gain valuable experience, and so on, for whom what is more important - emphasize the necessary.

                However, if Iran’s air defense is indeed the way it is advertised, then there are hardly any people willing to take revenge at the cost of their own lives.

    With a total mass of aerial bombs of 13,6 tons, the mass of the warhead is 2700 kilograms.
    And not such an easy "bomb"
    The U.S. Air Force command previously stated that GBU-57 will be used to destroy underground uranium enrichment plants in Iran and the DPRK military facilities hidden in the rock mass.
    But in order to carry out such bombing, it is necessary before that to qualitatively suppress the entire air defense system, but how long will it take?

      But, in order to conduct such a bombing, NATO would qualitatively suppress the entire air defense system before that, and how long does it take?
      It depends on the air defense and whom. For even the same equipment in different hands behaves differently. The history of the wars of the 20th century in the Middle East is a confirmation of this. And no need to discount Spirit. This car, depending on which country is terrible. And to whom is the target. Which never flies to the borders. And the bombs are really interesting from a military point of view. I was especially interested in their double use. (See my first comment)

        In principle, the usual tactics, as well as the DT MBT are now being overcome, the first shell destroys it, the second goes to break through the main reservation ...

        Dual use - further development, in response to increased protection.

    Iran is waiting for the fate of Iraq, if there is a nada. Ironed by bombing so that no stone is left on the stone. All you need is a wish, Iran to derail with the support of the satellites and the US BV countries is entirely feasible.

    let the Persians upgrade their S-300s ... all the same, they are all underground, in deep holes, it would not hurt to upgrade at least the missiles to it (the S-300 complex). and then let anyone just try to fly in or fly by. Blame yourself later.

    They will fly in and do not ask permission. Iran has 4 dizions. One is covering the capital of EMNIP, one is the nuclear power plant in Bushehr, and two other enterprises of the OYaK of Iran. And this enterprise is not unique. Therefore, the remaining 2 divisions are "smeared" over the object. This means that it is not difficult to overcome this milestone ...

    Americans then know very well by which system they conduct averaged calculations

    Averaged calculations for weapons? Well, ladies ... let it be so. And the second ... they rock the rock, then they put explosives into the pits and explode them into pieces, dig them ... it's like rolling a square .. in principle, it’s possible. So good luck with their GBU to break through a multimeter rock ...
    Therefore .. they can calculate anything, the main thing is that they would not get a new fantastic movie universe ..

    Gennady! But does someone say that Americans must by all means make their way through the thickness of the rock in order to hit the target (factory in Fordo)
    Any underground structure has a lot of unmasking signs /

    The first unmasking sign.
    Entrances and exits of the rock complex. No one forces to pierce the entire thickness of the rocky arch of the plant, but to put ammunition at the entrances is not a problem. And the entrances will be bombarded with hundreds, or even thousands of tons of rock. And where the inputs and outputs are known. Americans have been following these businesses for years. So where and what is known. Moreover, the removal of the selected soil will be through these inputs exits.

    Second unmasking sign
    Conclusions of the air supply system. And there is not a frail amount of space and, accordingly, the air supply system is quite serious. And the conclusion of part of this single system will lead to the fact that it will be impossible to be in the premises.

    Third unmasking sign
    The power supply system of this underground enterprise. Inside, of course, there may be backup diesel generators, but taking into account the fact that the latest Russian centrifuges have a consumption of 50 kW / hour for EPP, and in the USA this value is approximately 2700 kW / hour, I think that Iranian centrifuges have this parameter rather closer to American than to Russian.
    The number of centrifuges at the Fordo facility is currently several hundred centrifuges. And if the Iranians begin full-scale deployment of their nuclear program, energy consumption will increase many times over. And this means that the power plant will be another target for destruction. And if not the station itself, then the power line. so the problems are solved

    Iran has more than enough enemies, only warriors from those enemies are not very, therefore the USA is scurrying around, they all understand perfectly.
