US' top general tells lawmakers
The US military did not use bunker-buster bombs on one of Iran's largest nuclear sites last weekend because the site is so deep that the bombs likely would not have been effective, the US' top general told senators during a briefing on Thursday. The comment by Joint Chiefs of Staff Chairman Gen. Dan Caine, which was described by three people who heard his remarks and a fourth who was briefed on them, is the first known explanation given for why the US military did not use the Massive Ordnance Penetrator bomb against the Isfahan site in central Iran. US officials believe Isfahan's underground structures house nearly 60% of Iran's enriched uranium stockpile, which Iran would need in order to ever produce a nuclear weapon. US B2 bombers dropped over a dozen bunker-buster bombs on Iran's Fordow and Natanz nuclear sites. But Isfahan was only struck by Tomahawk missiles launched from a US submarine. The classified briefing to lawmakers was conducted by Caine, Defense Secretary Pete Hegseth, Secretary of State Marco Rubio and CIA Director John Ratcliffe. Spokespeople for Caine did not return requests for comment. Democratic Sen. Chris Murphy told CNN on Thursday night after receiving the briefing that some of Iran's capabilities 'are so far underground that we can never reach them. So they have the ability to move a lot of what has been saved into areas where there's no American bombing capacity that can reach it.' An early assessment produced by the Defense Intelligence Agency in the day after the US strikes said the attack did not destroy the core components of the country's nuclear program, including its enriched uranium, and likely only set the program back by months, CNN has reported. It also said Iran may have moved some of the enriched uranium out of the sites before they were attacked. The Trump officials who briefed lawmakers this week sidestepped questions about the whereabouts of Iran's stockpile of already-enriched uranium. President Donald Trump again claimed Friday that nothing was moved from the three Iranian sites before the US military operation. But Republican lawmakers emerged from the classified briefings on Thursday acknowledging that the US military strikes may not have eliminated all of Iran's nuclear materials. But they argued that doing so was not part of the military's mission. 'There is enriched uranium in the facilities that moves around, but that was not the intent or the mission,' Republican Rep. Michael McCaul of Texas told CNN. 'My understanding is most of it's still there. So we need a full accounting. That's why Iran has to come to the table directly with us, so the (International Atomic Energy Agency) can account for every ounce of enriched uranium that's there. I don't think it's going out of the country, I think it's at the facilities.' 'The purpose of the mission was to eliminate certain particular aspects of their nuclear program. Those were eliminated. To get rid of the nuclear material was not part of the mission,' GOP Rep. Greg Murphy told CNN. 'Here's where we're at: the program was obliterated at those three sites. But they still have ambitions,' said Republican Sen. Lindsey Graham of South Carolina. 'I don't know where the 900 pounds of highly enriched uranium exists. But it wasn't part of the targets there.' '(The sites) were obliterated. Nobody can use them anytime soon,' Graham also said. Weapons expert and professor at the Middlebury Institute of International Studies Jeffrey Lewis told CNN that commercial satellite images show that Iran has accessed the tunnels at Isfahan. 'There were a moderate number of vehicles present at Isfahan on June 26 and at least one of the tunnel entrances was cleared of obstructions by mid-morning June 27,' Lewis said. 'If Iran's stockpile of (highly enriched uranium) was still in the tunnel when Iran sealed the entrances, it may be elsewhere now.' Additional satellite imagery captured on June 27 by Planet Labs show the entrance to the tunnels were open at the time, according to Lewis. The preliminary DIA assessment noted that the nuclear sites' above ground structures were moderately to severely damaged, CNN has reported. That damage could make it a lot harder for Iran to access any enriched uranium that does remain underground, sources said, something that Graham alluded to on Thursday. 'These strikes did a lot of damage to those three facilities,' Murphy, the Connecticut Democrat, told CNN on Thursday night. 'But Iran still has the know-how to put back together a nuclear program. And if they still have that enriched material, and if they still have centrifuges, and if they still have the capability to very quickly move those centrifuges into what we call a cascade, we have not set back that program by years. We have set it back by months.' Caine and Hegseth on Thursday said the military operation against Fordow went exactly as planned but did not mention the impacts to Isfahan and Natanz.

Pentagon releases jaw-dropping footage showing how 30,000-pound bunker-buster bombs work
Don't miss out on the headlines from Innovation. Followed categories will be added to My News. The Pentagon released stunning footage on Thursday showcasing exactly how 30,000-pound heavy-duty bunker-buster bombs work such as the ones used against Iran's nuclear sites demolished fortified targets deep underground. The video showed a GBU-57 series MOP (Massive Ordnance Penetrator) crashing into a target and kicking up a massive plume of dust moments before a blinding inferno appeared in a shaft during a test detonation.

Picture: Department of Defense Pilots who dropped the MOPs on Iran called the blast 'the brightest explosion' they ever saw, saying, 'it literally looked like daylight'. The MOPs used in the strike — which can only be dropped by a B-2 Stealth Bomber — were developed in 2009 after the US learned of the existence of the Fordow uranium enrichment plant. The bunker buster bombs do not leave craters like traditional bombs. Picture: Department of Defense A US Air Force B-2 Spirit landing after supporting Operation 'Midnight Hammer'.

Dan Caine explained to reporters during a press briefing on Thursday. 'Five [weapons] were tasked to enter the main shaft moved down into the complex at greater than a thousand feet per second, and explode in the mission space … All six weapons at each vent at Fordow [uranium enrichment plant] went exactly where they were intended to go.' Another angle displayed during the briefing showed an MOP hitting a target in slow motion and cutting through the arched interior of a second ventilation shaft without detonating as it moved its way deeper through the test facility. 'A bomb has three effects that causes damage: blast, fragmentation and overpressure,' he explained. 'In this case, the primary kill mechanisms in the mission space was a mix of overpressure and blast. 'Imagine what this looks like six times over.' Unidentified pilots inside a B-2 cockpit. Picture: US Air Force How the US bomber pilots reacted Lt. Gen. Caine explained that the heroic pilots who helped drop the bombs on three of Iran's nuclear facilities in a super-secret mission over the weekend were awed by the explosive power of the devices. 'We know that the trailing jets saw the first weapons function and the pilots stated, 'This was the brightest explosion that I've ever seen. It literally looked like daylight,'' he said. He also emphasised that the MOPs don't leave 'impact' craters — shooting down scepticism that the mission wasn't successful. Satellite images released after the mission show six holes where the deep-diving bombs appeared to have penetrated the mountain above Iran's Fordow nuclear plant. The press conference was seemingly intended to disabuse reporting on a leaked 'low confidence' Defense Intelligence Agency (DIA) assessment that Iran's nuclear program may have only been set back months, Lt. Gen. Caine played jaw-dropping footage of a MOP attack. A poster of the Fordow Fuel Enrichment Plant is displayed. Picture:/AFP Prior to developing the GBU-57, the military had assessed that it didn't have a 'weapon that could adequately strike and kill this target'. 'The crews that attacked Fordow were from the active duty Air Force and the Missouri Air National Guard,' Lt. Gen. Caine said of the pilots. 'The crews ranked from captain to colonel, and most were graduates of the Air Force weapons school headquartered at Nellis Air Force Base in Nevada. I will state for the record that there is no beach volleyball or football at the Air Force weapons school,' he added, making a Top Gun reference. Lt. Gen. Caine had a video call with the crews recently and noted that there were both men and women involved in the daring attack. 'This felt like the Super Bowl, the thousands of scientists, airmen and maintainers all coming together,' he remarked. 'One last story about people. When the crews went to work on Friday, they kissed their loved ones goodbye, not knowing when or if they'd be home. Pete Hegseth, left, with the Chairman of the Joint Chiefs of Staff. Picture:/AFP 'Late on Saturday night, their families became aware of what was happening, and on Sunday, when those jets returned … their families were there, flags flying and tears flowing. I have chills, literally talking about this.' The country's highest-ranking military officer underscored that 'our forces remain on a high state of readiness in the region, prepared to defend themselves'. 'Our adversaries around the world should know that there are other DTRA [Defense Threat Reduction Agency] team members out there studying targets for the same amount of time, and we'll continue to do so,' he said of the group that developed the MOPs to use against Fordow. At one point during the briefing, Defense Secretary Pete Hegseth, who raged at the press repeatedly, was pressed about why he congratulated the 'boys' for the successful mission. 'I'm very proud of that female pilot, just like I'm very proud of those male pilots — and I don't care if it's a male or female in that cockpit, and the American people don't care,' Mr Hegseth clapped back. 'We don't play your little games.'

How the US Used Its Bunker-Buster Bombs at Iranian Nuclear Sites
The deep penetrating bombs that the US dropped into two Iranian nuclear facilities were designed specifically for those sites and were the result of more than 15 years of intelligence and weapons design work, the Pentagon's top leaders said Thursday. Defense Secretary Pete Hegseth and Gen. Dan Caine, chairman of the Joint Chiefs of Staff, said at a press briefing that they are confident the weapons struck exactly as planned. Caine, the nation's top military officer, offered new details about the work that went into building the 'bunker-buster' bombs and how the US used them to burrow into the Iranian sites. He sought to show the level of destruction but did not directly address President Donald Trump's assertion that Tehran's nuclear program has been 'obliterated.' Classified briefing 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,' Caine said. That turned out to be the Fordo fuel enrichment plant, with construction believed to have started around 2006. It became operational in 2009, the same year Tehran publicly acknowledged its existence. The classified briefing was shown in 2009 to a Defense Threat Reduction Agency officer, who with a colleague 'lived and breathed' Fordo for the next 15 years, studying the geology, construction dig, the earth moved and 'every piece of equipment going in and every piece of equipment going out," Caine said. What they concluded: The US didn't have a bomb that could destroy those sites. So the Pentagon got to work, Caine said. 'We had so many Ph.D.s working on the mock program — doing modeling and simulation — that we were quietly and in a secret way the biggest users of supercomputer hours within the United States of America,' he said. How the bunker busters are designed The 30,000-pound bomb is comprised of steel, explosives and a fuse programmed to a specific detonation time. The longer the fuse, the deeper the weapon will penetrate before exploding. Over the years, the military tested and retested it hundreds of times on mock facilities, Caine said. Crews fine-tuned the bombs to detonate in the mock enrichment rooms, delaying detonation until they had reached a position to send a pressure blast through open tunnels to destroy equipment underground. How the US said it bombed an Iranian underground nuclear facility Fordo had two main ventilation routes into the underground facility and officials carefully eyed these entry points as a way to target the site. Each route had three shafts — a main shaft and a smaller shaft on either side, which looked almost like a pitchfork in graphics provided by the Pentagon. In the days preceding the US attack, Iran placed large concrete slabs on top of both ventilation routes to try to protect them, Caine said. In response, the US crafted an attack plan where six bunker-buster bombs would be used against each ventilation route, using the main shaft as a way down into the enrichment facility. 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. 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 Fordo, with six on each ventilation route, two more hit Iran's main Natanz facility, Caine said. Each crew was able to confirm detonation as they saw the bombs drop from the aircraft in front of them: 'We know that the trailing jets saw the first weapons function,' Caine said. The pilots reported back that it was the brightest explosion they had ever seen — that it looked like daylight, he said. Questions remain about the whereabouts of Iran's highly enriched uranium Caine said the munitions were built, tested and loaded properly, guided to their intended targets and then exploded as designed. 'Iran's nuclear facilities have been destroyed,' Hegseth said. However, questions remained as to whether the highly enriched uranium that Iran would need to develop a nuclear weapon was at the site at the time. Asked repeatedly, Hegseth did not say if the uranium had been destroyed or moved. 'I'm not aware of any intelligence that I've reviewed that says things were not where they were supposed to be — moved or otherwise,' Hegseth said.

Power of bunker-buster bombs Trump used on Iran revealed
The massive destructive power of the 30,000 pound bunker-buster bombs Donald Trump ordered to be dropped in Iran 's nuclear sites was put on full display in a newly released video. During a Pentagon press conference days after the strikes, Defense Secretary Pete Hegseth and Chairman of the Joint Chiefs of Staff Dan Caine reiterated that Operation Midnight Hammer was a success. The mission utilized over 125 planes and seven B-2 stealth bombers carrying a total of 14 bunker-buster bombs meant for Iran's mountainous Fordow uranium enrichment facilities. Trump said the site was 'obliterated' after the strike, but a leaked top secret intelligence assessment revealed that Fordow could be rebuilt in months - something the Pentagon and White House have furiously pushed back against. To prove the mission's effectiveness, Caine played a video showing exactly how the GBU-57 'bunker-buster' bombs work. In the video, a 20-foot-long and 30,000-pound GBU-57 can be seen slamming into the roof of a cave with wicked force. Another angle shows the cave entrance and the bomb passing into the chamber before detonating in a fiery explosion. U.S. B-2 stealth bombers dropped a total of 14 GBU-57s on Iran's Fordow nuclear enrichment facility, which is built deep under a mountain range. 'Unlike a normal surface bomb, you won't see an impact crater because they're designed to deeply bury and then function,' Caine explained. 'All six weapons at each vent at Fordow went exactly where they were intended to go,' he added. Though the video was a test of the GBU-57, and not footage from the actual operation, Caine said it proves how satellite imagery of the site cannot fully ascertain the damage caused within the subterranean nuclear site. The explosion was so vicious that one of the B-2 pilots said it made the night sky turn into 'daylight.' '[It was] the brightest explosion that I've ever seen,' Caine claimed the pilot said. 'It literally looked like daylight.' Dropped from the B-2s, the GBU-57s arrived on their targets traveling 1,000-feet per second, the chairman of the Joint Chiefs shared. Similar to the plot of 'Top Gun: Maverick,' the bombs were aimed at the buried nuclear site's ventilation shafts - the most vulnerable parts of the expansive facility. Since the site had two main ventilation shafts, six bombs were dropped on each. The video was 'a culmination of over 15 years of development and testing,' Caine said.
