WASHINGTON — In a significant escalation of the ongoing conflict in the Middle East, U.S. Central Command (CENTCOM) confirmed Tuesday that American forces launched a series of high-intensity airstrikes against hardened Iranian military installations along the strategic Strait of Hormuz.
The operation utilized multiple GBU-72 Advanced 5K Penetrator munitions—5,000-pound “bunker buster” bombs—designed specifically to neutralize deeply buried or reinforced targets. According to military officials, the strikes successfully hit anti-ship cruise missile sites that posed a direct and “imminent risk” to international shipping in the world’s most critical energy chokepoint.
Strategic Neutralization of the ‘Chokehold’
The Strait of Hormuz, which facilitates the passage of approximately 20% of the world’s petroleum liquids, has been functionally closed since early March following a blockade by Iranian forces. This blockade was a retaliation for the joint U.S.-Israeli strikes on February 28 that killed Iran’s Supreme Leader, Ayatollah Ali Khamenei.
“U.S. forces successfully employed multiple 5,000-pound deep penetrator munitions on hardened Iranian missile sites,” CENTCOM stated via its official X account. “The Iranian anti-ship cruise missiles in these sites posed a risk to international shipping in the strait.”
The use of the GBU-72 marks a shift in tactical intensity. While less massive than the 30,000-pound GBU-57 used against nuclear facilities in 2025, the 5,000-pound class is optimized for the rugged, coastal terrain of the Hormuz coastline, where Iran has long embedded its “area-denial” batteries within mountain bunkers and reinforced concrete silos.
Economic and Diplomatic Fallout
The military action comes as global oil prices hover above $100 per barrel, driven by the collapse of maritime traffic through the Persian Gulf.
- Allied Hesitation: President Donald Trump expressed “disappointment” on Tuesday after key NATO allies, including the UK and Spain, reportedly declined to participate in a joint naval escort mission.
- Independent Action: In response to the lack of coalition support, the President asserted that the U.S. does “not need the help of anyone” to secure the waterway, framing the strikes as a unilateral necessity to protect global trade.
- Internal Dissent: The strikes have triggered fallout within the administration. Joe Kent, Director of the National Counterterrorism Center, resigned Tuesday, stating he could not “in good conscience” support the current trajectory of the war.
The Technological Edge: What is a ‘Deep Penetrator’?
The munitions used in this operation represent the pinnacle of conventional “bunker-busting” technology.
Unlike standard ordnance that explodes on contact, these weapons use a delayed-fuzing system. The bomb’s casing is forged from a high-strength steel alloy, allowing it to burrow tens of feet into the earth or through several meters of reinforced concrete before the warhead ignites, collapsing underground infrastructure from the inside out.
Current Status of the Strait
While the strikes have degraded Iran’s coastal battery capabilities, the waterway remains treacherous. Intelligence reports suggest the Islamic Revolutionary Guard Corps (IRGC) has deployed a dense network of naval mines and unmanned surface vessels (USVs) to maintain the blockade.
In a rare move of cooperation, France and the United Kingdom have reportedly positioned mine-hunting drones near the region to assist in clearing the shipping lanes, offering a “low-risk” alternative to direct naval combat.
