Unprecedented New View Of BLU-109 Bunker Buster Strike That Killed Hezbollah's Leadership

Closed-circuit television video has emerged offering a new very up-close and personal view of the large-scale and highly-coordinated strike on Hezbollah's command bunker in Dahieh, a southern Beirut suburb and a stronghold of the militant organization, on September 27th, 2024. GBU-31/B Joint Direct Attack Munition (JDAM) bombs with BLU-109/B bunker-busting warheads were the primary weapon used for this attack that killed Hezbollah's leader Hassan Nasrallah, as well as other top officials. It has been reported that dozens of civilians were killed and hundreds more were wounded in the attack.
The decapitation strike aimed at the large bunker buried beneath a residential area was one of the key operations that sent the Iranian-backed militant group far off kilter, allowing for Israel's air and ground operations to have a far greater effect than they would have otherwise while limiting Hezbollah's ability to respond in kind. The pager and walkie-talkie sabotage operation that preceded this strike was another.
Hezbollah remains heavily degraded today with the fall of the Assad regime in Syria, a key ally outside of Tehran, being another massive blow that came months later.
The video below shows what appears to be a normal day in Dahieh, with people moving about, including two motorcyclists that are shown in-frame. Then the bunker busters arrive. One is seen burrowing deep through the concrete roadway, narrowly missing one of the motorcyclists, followed by a massive subterranean explosion that 'lifts' the entire surrounding area. This is exactly the effect of a bunker buster like the BLU-109. The bomb's tough casing allows it to penetrate deep underground with its delayed fuzing detonating the warhead at a predetermined depth or even level of a reinforced compound.

The strikes that killed Nasrallah were the result of decades of Israeli intelligence efforts to infiltrate Hezbollah and being able to the movements of its reclusive leader, according to multiple subsequent reports. Israel's unprecedented sowing of pagers and other electronics containing small explosive charges into Hezbollah's supply chains had already underscored its deep penetration into the group.
Israel's strike is known to have involved the use of many GBU-31/Bs with BLU-109/B warheads delivered by at least eight F-15Is. Pre-strike imagery of the F-15s shows eight of them loaded to the brim with seven BLU-109/B-equipped JDAMs each, for a total of 56 bombs for the strike. Other reports put the number at over 80 bombs.

It's unclear whether or not Israel has received any BLU-116/Bs, a 2,000-pound-class penetrator featuring various improvements over the BLU-109/B, including an advanced smart fuze and the ability to punch through nearly 12 feet of reinforced concrete. The development of another 2,000-pound-class penetrator, the BLU-137/B, as a replacement for the BLU-109/B also began at least a decade ago, but to what extent that weapon is even in U.S. military service currently is not clear. Just today, the U.S. government approved the potential sale to Israel of additional JDAM kits specifically for use with the BLU-109/B, as well as precision-guided bombs and related components.

Video taken of the Israeli strike from afar shows highly precise targeteering that aimed to defeat the bunker system totally in one barrage. Images that emerged after the strike show giant craters and other impact areas spaced to provide continuous effects across a subterranean area. Different fuzing could have been employed to take out multiple levels of the complex and/or to ensure areas where the depth of the target wasn't known still resulted in the desired level of destruction. Layering in multiple BLU-109/Bs atop each other, allowing them to 'dig' deeper than they could if used in a singular manner, is also likely to have been used as there are reports that the bunker was located as deep as 60 feet below the surface.

Regardless, the video is perhaps the most up-close view we have seen of the real-world effects of these weapons and their ability to reliably drill down through the soil and concrete to reach their intended target.

Russia's former president says countries are lining up to give Iran their nukes. Analysts are calling his bluff.

Analysts are casting doubt on Russia's former president's claim that "a number of countries" were considering supplying nuclear warheads to Iran after the Pentagon's salvo of bunker-buster strikes there. Dmitry Medvedev, who was president from 2008 to 2012 and is a top aide to Russian leader Vladimir Putin, didn't specify which countries he was referring to in his Telegram post on Sunday. In his post, he downplayed the damage dealt to Iran's vital nuclear sites. As news of the strikes broke on Saturday, the Pentagon was careful to say that it was still assessing the destruction caused by the 14 GBU-57 Massive Ordnance Penetrator bombs and multiple Tomahawk missiles it fired at Iran's nuclear sites. Medvedev wrote that the strikes had "entangled" the US in a new conflict. "A number of countries are ready to directly supply Iran with their own nuclear warheads," he added. Nuclear weapons analysts speaking to Business Insider said they doubted that Medvedev's statement on such transfers is credible. "It's impossible in practice because nuclear weapons are not like a bomb or just something you can carry in a suitcase," said Pavel Podvig, a senior researcher in the United Nations Institute for Disarmament Research's weapons of mass destruction program. Nuclear warheads come as an entire system, with people who need to be trained to keep and service them safely, as well as maintenance facilities and equipment. Even tactical nukes, which are more portable and produce a smaller blast, need high-level storage, Podvig added. "Unless you create a nuclear program or almost a nuclear program in the country, there is no way to just give your nuclear weapons to them," he said. Simply giving such a warhead to another country would break the first article of the UN's Nuclear Non-Proliferation Treaty, which Russia and China have signed. Podvig said that in Europe, where the US stations nuclear weapons, the warheads are in American custody. The same can be said of Russia's nuclear weapons in Belarus. "I don't see this being done technically," Podvig said. Politically, Medvedev could likely only be referring to three countries, said Adam Lowther, a cofounder and the vice president of research at the Ohio-registered think tank National Institute for Deterrence Studies. North Korea, China, and Russia are the only nuclear-armed states considered adversaries or rivals to the US. And Lowther said all three know that supplying Iran with nuclear weapons, even just as a deterrent, would risk intense escalation from the US and Israel. "When you give somebody a nuclear weapon, and they can use it, you can't guarantee how they're going to use it," Lowther said. He added that with Tel Aviv and Washington so focused on preventing Iran from fielding nuclear weapons, Tehran would likely only have two choices if it does receive a warhead: Use the bomb or lose it. And if Iran detonates a gifted nuke, Lowther added, American forensics would easily be able to trace the fissile material and bomb design to identify where the weapon originated. "Then that country would be on the US' hit list," Lowther said. Medvedev is known to make bold, hawkish statements toward Ukraine and the US since the outset of the full-scale Russian invasion. He serves as the deputy chairman — second in rank to Putin — of the Kremlin's security council. His rhetoric has often run parallel to the Kremlin's nuclear threats, repeatedly issued as warnings to the West over military aid to Ukraine. Moscow, however, has consistently not followed through with those threats, even when the US escalated its level of assistance to Kyiv. Lowther said he believes Medvedev's statement was a play against Ukraine, a bid to reduce the West's willingness to help Kyiv. "The Russians say: 'You know what? You give the Ukrainians these weapons? Well, we can give the Iranians weapons as well,'" he said. The Israel Defense Forces declined to comment on Medvedev's remarks.

How the US bombarded Iranian nuclear sites without detection

DUBAI, United Arab Emirates -- It was an unprecedented attack years in the making, with some last-minute misdirection meant to give the operation a powerful element of surprise. U.S. pilots dropped 30,000-pound bombs early Sunday on two key underground uranium enrichment plants in Iran, delivering what American military leaders believe is a knockout blow to a nuclear program that Israel views as an existential threat and has been pummeling for more than a week. American sailors bolstered the surprise mission by firing dozens of cruise missiles from a submarine toward at least one other site. Dubbed Operation Midnight Hammer, U.S. officials say the plan was characterized by a 'precision strike' that 'devastated the Iranian nuclear program,' even as they acknowledged an assessment was ongoing. For its part, Iran denied that any significant damage had been done, and the Islamic Republic pledged to retaliate. Taking off from the U.S. heartland, B-2 stealth bombers delivered a total of 420,000 pounds of explosives, aided by an armada of refueling tankers and fighter jets — some of which launched their own weapons. U.S. officials said Iran neither detected the inbound fusillade, nor mustered a shot at the stealthy American jets. The operation relied on a series of deceptive tactics and decoys to maintain the secrecy, U.S. officials said hours after the attack, which was preceded by nine days of Israeli attacks that debilitated Iran's military leadership and air defenses. Even before the planes took off, elements of misdirection were already in play. After setting parts of the plan in motion, Trump publicly announced Thursday that he'd make a decision within two weeks on whether to strike Iran — ostensibly to allow additional time for negotiations, but in actuality masking the impending attack. One group of B-2 stealth bombers traveled west from Missouri on Saturday as decoys, drawing the attention of amateur plane spotters, government officials and some media as they headed toward a U.S. air base in the Pacific. At the same time, seven other B-2s carrying two 'bunker buster' bombs apiece flew eastward, keeping communications to a minimum so as not to draw any attention. Air Force Gen. Dan Caine, the chairman of the Joint Chiefs of Staff, said at Sunday's briefing that it was all "part of a plan to maintain tactical surprise' and that only 'an extremely small number of planners and key leaders' knew about it in Washington and Florida, where U.S. Central Command is based. After 18 hours of furtive flying that required aerial refueling, the armed B-2 Spirit bombers, each with two crew members, arrived on time and without detection in the Eastern Mediterranean, from where they launched their attack runs. Before crossing into Iran, the B-2s were escorted by stealthy U.S. fighter jets and reconnaissance aircraft. A graphic released by the Pentagon showed the flight route as passing over Lebanon, Syria and Iraq. It was unclear whether those countries were notified of the U.S. overflight in advance. Most U.S. lawmakers were also kept in the dark, with some Republicans saying they were provided a brief heads-up by the White House before the strike. 'Our B-2s went in and out and back without the world knowing at all,' Secretary of Defense Pete Hegseth told reporters Sunday. About an hour before the B-2s entered Iran, Caine said that a U.S. submarine in the region launched more than two dozen Tomahawk cruise missiles against key targets, including a site in Isfahan where uranium is prepared for enrichment. As the U.S. bombers approached their targets, they watched out for Iranian fighter jets and surface-to-air missiles, but encountered none. At 6:40 p.m. in Washington and 2:10 a.m. in Tehran, the first B-2 bomber dropped its pair of GBU-57 massive ordnance penetrators on the deeply buried Fordo uranium enrichment plant. It was the first time these so-called 'bunker busters' had ever been used in combat. Each 30,000-pound bomb is designed to burrow into the ground before detonating a massive warhead. The Fordo site received the bulk of the bombardment, though a couple of the enormous bombs were also dropped on a uranium enrichment site at Natanz. The U.S. bombs fell for about half an hour, with cruise missiles fired from submarines being the last American weapons to hit their targets, which included a third nuclear site at Isfahan, Caine said. Both Iran and the U.N. nuclear watchdog said there were no immediate signs of radioactive contamination around the sites. The mission included: — 75 precision-guided weapons: these included 14 GBU-57 'bunker buster' bombs deployed by the seven B-2 Spirit stealth bombers, and more than two-dozen Tomahawk cruise missiles launched from a U.S. submarine. — 125 aircraft, including the B-2 bombers, fighter jets and refueling planes. Hegseth said Sunday that 'our boys in those bombers are on their way home right now.' But a U.S. official said one woman was among those piloting the B-2 bombers. The official spoke on the condition of anonymity because they were not authorized to speak about the mission publicly. Caine said the use of the bunker-buster bombs made the mission historic, as did other elements. 'This was the largest B-2 operational strike in U.S. history, and the second longest B-2 mission ever flown, exceeded only by those in the days following 9/11," he told reporters Sunday. ___

Israel-Iran live updates: Iran's Khamenei says 'punishment' of Israel will continue

Israel, the ayatollah said, "has made a grave mistake." The United States struck three nuclear sites in Iran on Saturday, President Donald Trump announced. B-2 bombers dropped a number of Massive Ordnance Penetrator bombs -- known as "bunker busters" -- during the U.S. mission over Iran, U.S. officials said. Trump on Sunday said that "Monumental Damage was done to all Nuclear sites in Iran," though Chairman of the Joint Chiefs of Staff Gen. Dan Caine said a full battle damage assessment is still pending. Jun 22, 2025, 11:29 PM EDT 'Bullseye': Trump says damage to Iran nuclear sites is 'far below ground level' President Donald Trump took to his social media platform on Sunday night to further detail the U.S. strikes against Iran's nuclear facilities. "Monumental Damage was done to all Nuclear sites in Iran, as shown by satellite images. Obliteration is an accurate term!" the president wrote on Truth Social. Several B-2 bombers were used in strikes on three of Iran's nuclear facilities -- Fordo, Natanz and Isfahan. More than 125 aircraft participated in the mission, including seven B-2 Spirit stealth bombers, according to U.S. officials. Trump did not mention which location he was specifically referring to, but said, "The white structure shown is deeply imbedded into the rock, with even its roof well below ground level, and completely shielded from flame." "The biggest damage took place far below ground level. Bullseye!!!" Trump added of the strikes. -ABC News' Michelle Stoddart In an early morning message local time, Iran's supreme leader, Ayatollah Ali Khamenei, said the "punishment" of Israel will continue. Khamenei did not mention the United States or President Donald Trump in his statement. "The Zionist enemy has made a grave mistake, committed a great crime; it must be punished and is being punished; it is being punished right now," Khamenei wrote. -ABC News' Will Gretsky The State Department has issued a new worldwide caution alert prompted by the conflict between Israel and Iran, saying there is "potential for demonstrations against U.S. citizens and interests abroad." 'The conflict between Israel and Iran has resulted in disruptions to travel and periodic closure of airspace across the Middle East. There is the potential for demonstrations against U.S. citizens and interests abroad. The Department of State advises U.S. citizens worldwide to exercise increased caution,' the alert reads. Earlier this month, the State Department issued a regional alert related to the conflict, advising Americans in North Africa and the Middle East to exercise increased caution. In October 2023, the U.S. issued a similar worldwide caution alert stemming from the Oct. 7 attacks on Israel and ensuing military campaign in Gaza. -ABC News' Shannon Kingston
