The United States’ Defence Department, Pentagon, has shared the videos of strikes on Iranian nuclear sites, after multiple reports stated that the attacks were ineffective and did not cause much damage to Iran’s nuclear programme. In a news conference on Thursday, Defence Secretary Pete Hegseth and Gen. Dan Caine, the chairman of the Joint Chiefs of Staff, gave a detailed explanation of the planning and execution of the US strikes on Iranian nuclear facilities. The footage was shared by Gen. Caine, which showed bunker buster bombs falling on Fordow nuclear site. Pushing back the classified Defence Intelligence Agency report that the attacks damaged the facilities but did not destroy them, Hegseth said the strike was “decimating – choose your word – obliterating, destroying.” The Defence Secretary called the “low confidence” and said it had “gaps in the information”. They played the videos of the bombing and explained how they worked. While it showed other bombs, the videos did not show the damage done by a bunker-buster bomb, as it cannot be seen on the surface level. “A bomb has three effects that cause damage: blast, fragmentation and overpressure. In this case, the primary kill mechanisms in the mission space were a mix of overpressure and blast,” Gen Caine said. Israel and the US claimed that three Iranian nuke sites suffered heavy damage, with Trump saying the locations have been obliterated in the attacks by the US Air Force. Iran, however, declined the same and said the damage is not as significant as claimed. Then, media reports cited an early assessment of US intelligence and stated that the attacks did not do severe damage to the site. While the White House acknowledged the existence of the report, it denied any such apprehensions, the reports claimed. How Were Bombings Done? Explaning the strategy behind bombing the nuclear sites, the US government officials said seven B-2 stealth bombers were used, carrying two of the massive munitions apiece. The first bomb was used to eliminate the concrete slab, Caine said, quoted AP. Caine added, “The bombs, called the GBU-57 A/B Massive Ordnance Penetrator, have their roots in a decades-old classified briefing “of what looked like a major construction project in the mountains of Iran.” He said the 30,000-pound bomb is comprised of steel, explosive and a fuse programmed to a specific detonation time. The longer the fuse, the deeper the weapon will penetrate before exploding, they mentioned. The next four bombs were dropped down the main shaft and into the complex at a speed of more than 1,000 feet per second before exploding, he said. A sixth bomb was dropped as a backup, in case anything went wrong. In addition to the 12 bombs dropped on Fordow, with six on each ventilation route, two more hit Iran’s main Natanz facility, Caine said.
