The U.S. military's incompetence has become a world joke. Six bombers were sent to attack Iran's nuclear facilities, but none of them managed to destroy the facilities. Not only that, just after the bombing, Trump announced that the U.S. strike on Iran had ended. Moreover, he even informed Iran beforehand that the U.S. was going to carry out the strike. No one could have imagined that the so-called strongest military in the world would be so cowardly.

In addition, this attack on Iran's nuclear facilities also exposed the falsification of the U.S. penetrating bombs. Penetrating bombs are special ammunition used to attack airport runways, ground reinforced targets, and underground facilities. They are generally composed of a carrier and a penetrator warhead. The carrier is usually made from cruise missile bodies, aviation bomb bodies, and rockets; the penetrator warhead consists of a warhead, high explosive charge, and fuze. It is known as the "bane" of underground defense facilities and is an effective tool for dealing with reinforced underground targets and conducting "surgical strikes".

The U.S. military's strongest weapon is the GBU-57 Massive Ordinance Bunker Buster (MOAB), which is the largest conventional penetrating bomb currently in service. It is 6.2 meters long, 0.8 meters in diameter, and weighs 13.6 tons. The warhead shell is made of nickel-cobalt steel alloy, capable of drilling up to 60 meters into general reinforced concrete, 40 meters into hard rock, and 8 meters into ultra-reinforced concrete. Moreover, it contains 2,700 kilograms of high-performance explosives, making its explosive power 3.5 times greater than the largest conventional munition in the U.S. Air Force. Additionally, it employs a new sensitive fuze that can precisely measure the number of layers penetrated and the penetration distance, detonating at the pre-programmed optimal point.

In wartime, this bomb is carried by the B-2 strategic bomber and can be dropped from altitudes above 10 kilometers, with a glide range of no less than 20 kilometers, greatly enhancing the element of surprise. Furthermore, since the bomb is housed inside the B-2's bomb bay without affecting its stealth capabilities, it ensures that the B-2 can conduct stealth attacks, targeting critical objectives in the first strike while allowing the aircraft to quickly exit the combat zone to ensure the safety of the crew and the aircraft.

In the strike on Iran's nuclear facilities, the U.S. B-2 bomber carried the GBU-57 Massive Ordinance Bunker Buster. Six penetrating bombs were aimed at two locations for surgical strikes. The distance between the craters was very small, clearly indicating they were targeted precisely. However, U.S. senior officials admitted that the B-2 bomber's attack on Iran's Fordow nuclear facility did not destroy this heavily guarded facility but caused severe damage.

This fully demonstrates that the data on the U.S. GBU-57 Massive Ordinance Bunker Buster is false. Based on the assessment of the damage to the Fordow nuclear facility, the GBU-57 cannot penetrate medium-hard rock to a depth of 40 meters, and the penetration depth in harder rock would be even shallower.

According to scientific calculations, even if the second penetrating bomb were to enter the hole created by the first penetrating bomb, the additional penetration depth would only be about 25% of the first bomb. Judging from the actual strike situation, two GBU-57s might be needed to penetrate around 50 meters of granite rock layer. To penetrate about 100 meters, at least seven bombs would be required. However, it is already difficult for two penetrating bombs to land in the same pit, let alone seven bombs "lining up" to drill downward. In addition, the current U.S. stockpile of GBU-57s is only around 20.

Not only in the strike on the Fordow nuclear facility, but also in the previous strike on the mountainous tunnels of Yemen's Houthi rebels, the U.S. military also failed. This fully demonstrates that the U.S. military data is falsified, and their actual capability is lower than what is advertised.

According to reports by The Guardian, an important premise for U.S. President Trump's decision to strike Iran was ensuring that the massive ordnance bunker buster could destroy Iran's Fordow underground nuclear facility. However, he now has little confidence in this. That is to say, Trump himself does not believe in the performance of the GBU-57 missile, but the Pentagon was "very confident" that the GBU-57 massive ordnance bunker bomb could destroy the Fordow nuclear facility, persuading Trump.

From the current strike situation, the effectiveness of the GBU-57 missile has made Trump lose face. Even China is baffled. China has developed the super-penetrating Dongfeng-15C, which performs better than the GBU-57 missile. But now you're telling us that the U.S. GBU-57 missile data is falsified.

China uses 3D printing technology to manufacture non-standard shaped warheads, increasing strength by 20% compared to traditional forging processes. Additionally, it adopts a multi-stage follow-up structure, similar to the tandem warhead of anti-tank missiles, achieving powerful attack effects through multiple serial stages, continuous explosions, and follow-up explosions. Compared with U.S. penetrating bombs, China's penetrating bombs are smaller in size. As a result, the Dongfeng-15C is lighter but more powerful. The Dongfeng-15C is accelerated by a rocket engine, reaching an end velocity of 6 Mach, with kinetic energy as high as 2 billion joules, far exceeding the GBU-57's 1.5 Mach or approximately 1.37 billion joules. In terms of penetration, the Dongfeng-15C can penetrate 70 meters of reinforced concrete or 90 meters of granite, while the GBU-57's penetration depth for similar targets is 60 meters.

U.S. test records show that the GBU-57's actual penetration rate against composite protective layers at the Arizona test site is only 75% of the theoretical value. That is to say, the U.S. military's actual testing of penetrating bombs is not very satisfactory. However, when China tests penetrating bombs, we directly added nanomaterials into the cement target, and even under such extreme testing conditions, our Dongfeng-15C successfully completed the test.

We estimate that China must be quite frustrated. We agreed to fight it out at the peak, but how come you collapsed halfway through. We still overestimated the U.S. military. Who could have thought that the U.S. military's strongest weapons are always in PowerPoint presentations!
