One of the characteristic targets for tactical aviation are a variety of protected and buried structures for various purposes. To defeat such targets, aircraft require special weapon - penetrating or concrete-piercing bombs. Such weapons are being developed in several countries and are widely used.

American nomenclature


The widest range of penetrating bombs has been developed and manufactured in the United States. Customers are offered several universal warheads with different design features and differing characteristics that can be used as part of various aerial bombs. Due to this, a good balance of performance and unification is achieved.

In 1985, the BLU-109 / B warhead entered service with the US Air Force. This product had a body 2,4 m long with a diameter of 370 mm with 25 mm walls. Inside the body was placed 240 kg of tritonal and a bottom fuse with a moderator. Modifications were developed with a different explosive or other effect. Thus, the BLU-118 / B product has a volumetric explosion charge that strikes manpower after breaking through a concrete shelter.

Warheads of the BLU-109 / B family of various modifications are used in four types of bombs and on the AGM-130 rocket. When falling on a target with an optimal speed, BLU-109 / B penetrates up to 1,5-1,8 m of reinforced concrete, after which an explosion occurs.

Despite its considerable age, BLU-109 / B are still in production. So, in FY2020. purchased more than 4200 such warheads with a total value of over $ 146 million. In 2021, it is planned to purchase 2 thousand units. $ 70 million

Of greatest interest in the concrete-piercing nomenclature of the US Air Force is the GBU-57A / B MOR bomb with a mass of 13,6 tons, which was put into service in 2012. Its fighting qualities are associated with the use of a BLU-127 / B warhead. Such a warhead weighs more than 2,4 tons and carries a large explosive charge. There is a satellite guidance system. Depending on the conditions, GBU-57A / B can penetrate more than 60 m of reinforced concrete.

In 2016, a new modification of the bomb, GBU-57E / B, with increased penetration characteristics was adopted. The serial production of MOP bombs has been going on since the beginning of the last decade and is not mass production, since the Air Force does not need large quantities of such weapons. In addition, it can only be used from long-range bombers B-52H and B-2A.

The tactical thermonuclear bomb B1997 Mod has been in service since 61. 11. It was made on the basis of the serial B61-7 using a new hardened body. Inside it is placed a charge of variable power, from 10 to 340 kt, controlled by a delayed fuse.

When falling at high speed, the B61-11 bomb penetrates obstacles up to 3-6 m thick. The lack of penetrating power, depending on the type of target and the depth of its location, is compensated by the power of the explosion. A thermonuclear warhead creates a powerful shock wave that destroys objects at depths of tens of meters.

Currently, the US Air Force is armed with six types of conventional warheads for concrete-piercing bombs and one thermonuclear warhead. They are able to punch from 1-1,5 m to 50-60 m of concrete with the subsequent defeat of manpower and equipment of the bunker. With their help, a significant number of bombs with one or another characteristic are being built. A number of samples of American design are supplied abroad - to NATO partners and non-aligned states.

Middle East progress


In the past, the Israeli Air Force had only American-made penetration bombs. In the future, measures were taken to create their own weapons of this class. The first example of this kind was the MPR-500 product from Elbit Systems, presented in 2012. As noted by the development organization, the purpose of the project was to create a bomb with the combat qualities of the American Mk 84 in the dimensions of the Mk 82. In addition, they provided unification with these products for the fuse, guidance systems, etc.

The MPR-500 has a streamlined, reinforced hull with tail rudders. Product weight - 230 kg. There is a satellite guidance system. When accelerating to 330 m / s, the bomb is capable of penetrating up to 1 m of reinforced concrete or 4 floors between floors. After breaking through the obstacle, a continuous defeat of manpower is ensured within a radius of 23-25 ​​m with the scattering of individual fragments up to 80-100 m.

The Elbit MPR-500 product is mass-produced and supplied to the Israeli Air Force. Cases of the combat use of such weapons are reported. Details are unknown, but high accuracy and effectiveness against protected objects is indicated.

Turkey presented its first version of a concrete-piercing bomb in 2016. TÜBİTAK SAGE has developed the NEB product. The penetrating warhead has a length of 2,6 m and a diameter of 457 mm. Weight - 870 kg. The warhead of the NEB type has two charges. Under the nose fairing is the PBXN-110, the leading cumulative explosive with explosives, which provides initial target penetration. Behind it is the main hardened case with a high-explosive charge of the PBXN-109 composition. A block with control and guidance equipment is connected to the tail section of the warhead - Turkish or foreign-made blocks are offered.

In the Turkish Air Force, the NEB aerial bomb should be used by F-4E / 2020 fighter-bombers. The minimum penetration of a warhead with two charges is declared at 2,1 m of reinforced concrete. The main charge ensures the defeat of manpower behind an obstacle within a radius of tens of meters.

In 2016, the NEB bomb entered service with the Turkish Air Force and, probably, went into series. There is no information about production, its volume and cost. The use for real purposes was also not reported.

BetAB series


In recent decades, the Russian Aerospace Forces have received several types of concrete-piercing bombs with different characteristics and capabilities. Products with different equipment are capable of effectively hitting both buried structures and runways. In addition, compatibility with all modern frontline strike aircraft is ensured.

The BetAB-500 air bomb is a 2,2 m long product with a diameter of 330 mm and a mass of less than 480 kg. Inside the thick-walled body with a strong head part 76 TNT is placed. On its basis, the BetAB-500U product was created, which is distinguished by the presence of a rocket booster. A solid propellant charge is placed in the tail part of its body, which provides acceleration when falling. Due to the introduction of the accelerator, the length of the bomb increased to 2,5 m, the mass - to 510 kg, but the explosive charge was reduced to 45 kg.

Gaining speed when falling, BetAB-500 (U) bombs are capable of penetrating more than 1,2 m of reinforced concrete and over 3 m of soil. The base BetAB-500 must be dropped from high altitudes. A product with an accelerator is applied from a height of 150 m - then it independently develops the required speed.

A specialized "assault" concrete-piercing bomb BetAB-500ShP has also been developed. Due to its special design, it shows increased efficiency against runways and other similar structures. This bomb is slightly longer than the other products and weighs only 424 kg and carries 350 kg of TNT. The bomb is equipped with an accelerator and a parachute. After the drop, a parachute is thrown, providing braking and giving the aircraft time to leave the danger zone. The accelerator then accelerates the bomb. BetAB-500ShP penetrates at least 550 mm of reinforced concrete, and when blown up, leaves a funnel with a diameter of 4-5 m.

Past and future


Penetrating (concrete-piercing) bombs in their current form appeared during the Cold War in connection with the active construction of buried and underground structures for the placement of tactically and strategically important objects. To combat them, new aircraft weapons were needed, nuclear and conventional. A number of samples of that time, as well as newer products of the same ideology, still remain in service.

In the course of current local conflicts, bunkers are not a common and frequent target for airstrikes. Nevertheless, concrete-piercing bombs are not only preserved in arsenals, but also continue to develop. It was in recent years that the most powerful samples were created, and the list of developers of such weapons was replenished with new countries. Some of them, as far as is known, even used such bombs in real operations.

Thus, concrete-piercing bombs, despite the limited range of tasks to be solved, remain an important component of the arsenals of the developed Air Force and will retain this status in the future. This means that the production of existing samples will continue, and new ones will come to replace them.

    Depending on conditions, GBU-57A / B can penetrate more than 60 m of reinforced concrete

    As far as I remember, up to 60 meters of soil. And then not any, but the most loose. And that's not a fact.
    60 meters, this is the height of an 18-storey building. It is unrealistic to pierce such a layer of reinforced concrete with a kinetic projectile. Only if an asteroid.
    Not every nuclear bomb will pierce this, remember the hospital in Hiroshima, which was under the epicenter of the explosion. It still stands as a monument.

          We are talking about the depth of penetration of the bomb before it detonates. Even 18 meters of reinforced concrete is problematic at first to make, and then to hammer it at the range with ammunition. Probably still a typo.

            The source reports that the bomb penetrates 200 feet (61 m) of 34 MPa concrete (roughly our M350), 26 feet of 69 MPa concrete (roughly our 750 M) or 130 feet (40 m) of moderately hard rock.

      all American numbers mean something like coarse dry sand. bunker concrete aka the rings of Iranian missile silos there are a meter of non-penetration with a concrete punch and they are also sewn up with steel.

      Yes, this is not in the air defense / about the case.
      You're right, it's about doctrine.
      Compare: Turkey, Incirlik airbase. This is where the Americans hang out with nuclear bombs.
      The base is clearly ready for air attacks.




      For example, the Lipetsk air center, an enemy air raid is not expected here.
      Because you will not find such a moron who will bomb an air base in Russia.
      But the barmaley can afford this (UAVs and other sabotage things). Therefore, it would not hurt to organize at least some kind of "roof". And the precipitation / weather / comfort for the staff has not been canceled. In winter, servicing equipment in an open field is still a pleasure.

        I myself was amazed when I flew from the GSVG, there are all aircraft in concrete hangars, taxiways from the hangar to the runway along a tangent, probably for take-off from the hangar. All aviation arrived in Tver in an open place like a ruler, wing to wing. And now I get along on Nothing has changed on the Kola Peninsula in Google maps. June 22, 1941 did not teach anything, the question arises, or is it a military secret.

        Well, in Syria, until the barmaley made a relatively successful raid on Khmeimim, no one thought to make the simplest gabions in the aircraft parking. Although even the Americans during the Vietnam War did not disdain such a fortification at an air base in Thailand.

          Kurds. But this is a Barmaley version.
          They do not have their own country.
          And there is nowhere to give an answer.
          In addition, most of the forces there are Turkish.
          Therefore, everything is hidden there.

          Syria (or rather Assad, if he felt that he was a kirdyk) from charm could also be shot out of all the trash.
          Potentially Iran. (They are not the first to bite the Americans. They can also bite the Turks)
          Potentially Iraq.
          Potentially Greece.
          The Turks have enemies all around. With everyone at knives.

          So yes. In Russia, they do not build shelters for aircraft that protect against attacks from other states. There is reason to believe that no one will risk it. But still, protection is needed from the Barmalei attacks. Yes, and in the open air with such weather for equipment and personnel is not ice. In order not to say later that the MiG-29 is gauno, 80% have rotted keels, etc.
          Su 57 is especially concerned. The paint must be sensitive. So that they don't stand under the hail, snow and ice. Reagents will not benefit the coating either.

            The Kurds do not have aviation, and the rest of the listed countries, if you decide, is a declaration of war and a game with one goal. And what about in the event of a major conflict with NATO countries, they will definitely bomb us. In this case, everyone says that then there will be a nuclear war and airfields will no longer matter, but what if yao is not used? If, for example, the United States gets bogged down in the Pacific Ocean with China and it is not up to the size of Yao with the Russian Federation, then parity in conventional weapons will be maintained, and no one will be the first to use Yao in Europe. In the Second World War, by the way, the Germans did not use chemical weapons even when ours stormed Berlin, and we did not use when the Nazis looked at Moscow through binoculars ... Not everything is so simple, there is no unity in the NATO countries, Turkey alone is great ... the chance that in the threatening period, some of the NATO countries will decide, fuck it. And in this case, the bombing will be ordinary, and the planes are lined up as targets and without hangars, you can shoot with a mortar ...

    It is also worth adding GBU-39. With its modest dimensions (Weight 130 kg, Length 1800 mm, Width 190 mm) The maximum range is 110 km and penetrates 1 meter of reinforced concrete, under 1 meter of ground.

        After FAB-500, a funnel remains, and after a concrete-piercing bomb a considerable hill remains, it is very difficult to remove and clear. Israel is to bomb the airfields of Egypt, Jordan and, it seems, Syria with similar bombs. As a result, it was not possible to clear quickly and the planes did not take off.

          Not only that, the bomb was smart. If she hoped that she would not be able to pierce the hood, then she would go back and attach herself back to the plane that dropped her, or to another free one. Imagine the plane returns to the base, and the bomb's rollers for the balls went in and it starts bombing the entire airfield with jumps. And if you still adapt a club to it, then it will sweep all the buildings of the airfield and the surrounding buildings in the distances reported in the instructions and how much heat and heat will be enough.

      As far as I remember, shaped charges used to be on several European bombs.
      Then they decided to abandon them.
      For the strength of the hull and the accelerator - gives much more results than the cumulative warhead.

      The Turks apparently followed the path. which 50-40 years ago showed its unpromising nature.

    To the left of the entrance to Fort No. 5 in König, there is a bunker with a reinforced concrete overlap of more than 3 meters, so, according to the agreements, it was supposed to be destroyed. They laid explosives, nothing happened. All the openings were filled, filled with water, and thawed in 4 parts in winter.
    This is up to 60 meters of reinforced concrete.

    Depending on conditions, GBU-57A / B can penetrate more than 60 m of reinforced concrete

    What are the conditions? Not too much load on the metal, it will not collapse to half

    We still need to increase the range of bombs with the same mass characteristics.

    The foreign "partners" have a sounded satellite guidance system, but what about the BatABs, something is not mentioned in the text.

    In the Vinnitsa region there is a remnant of the destroyed bunker of Hitler's headquarters, and during the retreat it was blown up by the Germans themselves. The tour guide told us that the thickness of the side walls was up to 6 meters of concrete, and the ceiling was 20 meters, on top of the ceiling there was a layer of rubber covering 8 meters, and above this rubber 1,5, 2-XNUMX meters of ground from above for planting trees to camouflage the object This rubber covering was intended for throwing bombs upwards.

    Americans will fight forever! Because it is a guarantee of the work of thousands of people, it is a guarantee of the development of industry and science. And most importantly, they don't need victory - they need leadership and process

      When reading about the anti-bunker bomb, doubts always arose.
      It is known that they try to make such bombs strong enough so that they would not collapse ahead of time when overcoming tens of meters of concrete or rocky soil, for example, they can be made from the barrels of decommissioned 155mm guns
      The question is, what will happen if, when it falls to the ground, this bomb encounters a foreign object such as an anti-tank mine or a 152mm projectile or just a powerful explosive charge, the concrete-piercing bomb will survive after detonating this "foreign object" or how? if the bomb itself does not detonate ahead of time or does not collapse, but simply bends or turns it sideways, then should its further journey through the rocks to the underground bunker stop or not?

    Of course, creating such a complex weapon is an achievement, but somehow it is not easy to see photos of the creators who proudly sit near the murder weapon.

    Well, I don't believe in breaking 60 m of reinforced concrete. I do not believe!
