Iran’s largest nuclear facility at Kharg has been leveled by U.S. B-2 bombers!
U.S. B-2 Stealth Bombers Devastate Iran’s Hardened Nuclear Sites in Historic Midnight Strike
Seven U.S. B-2 Spirit stealth bombers penetrated Iranian airspace and unleashed some of the most powerful conventional bombs ever used in combat against Iran’s heavily fortified nuclear infrastructure, in an extraordinary long-range operation that struck Fordow, Natanz and Isfahan and dramatically escalated the confrontation over Tehran’s nuclear program.
The operation, code-named Midnight Hammer, unfolded in darkness on June 22, 2025, after months of rising tensions and days of fighting between Iran and Israel.
At approximately 2:10 a.m. local time in Iran, the lead B-2 released two GBU-57 Massive Ordnance Penetrator bombs against Fordow, the deeply buried uranium enrichment complex constructed beneath a mountain south of Tehran.
More B-2s followed.
Within roughly 25 minutes, American forces had struck all three nuclear sites.
By the time the bombers turned for home, the United States had employed approximately 75 precision-guided weapons in one of the most complex American air operations in years.
Fourteen of those weapons were GBU-57 bunker busters weighing approximately 30,000 pounds each.
It was the weapon’s first operational use.
And the mission represented the largest B-2 operational strike in history.

Seven B-2s Disappear Into the Night
The operation began thousands of miles from Iran at Whiteman Air Force Base in Missouri.
A large B-2 bomber force took off from the continental United States. But what happened next was designed to confuse anyone attempting to determine where the bombers were going.
Some aircraft headed west toward the Pacific as part of a deception maneuver.
The real strike force went east.
Seven B-2 Spirits, each carrying two crew members, continued toward the Middle East while maintaining minimal communications.
Their journey required multiple aerial refuelings during an approximately 18-hour flight toward the target area.
American commanders were attempting something exceptionally difficult: moving a force of strategic bombers halfway around the world without giving Iran enough warning to prepare an effective defense.
As the aircraft approached Iranian airspace, other elements of the American military joined the operation.
Fourth- and fifth-generation fighters moved ahead of the bombers. Suppression weapons were prepared against Iranian surface-to-air missile systems. Intelligence and surveillance aircraft watched the battlespace.
Meanwhile, beneath the sea, another component of the attack was already moving into position.
A U.S. submarine launched more than two dozen Tomahawk cruise missiles against infrastructure at Isfahan.
Then the B-2s went after the hardest targets.
Fordow Was Built to Survive an Attack
Fordow presented a unique problem.
The uranium enrichment facility was not simply surrounded by concrete walls or conventional military fortifications.
It was buried beneath a mountain.
The complex had long been considered one of the most difficult nuclear targets in Iran because its underground location offered substantial protection against ordinary bombs.
That was precisely why the GBU-57 existed.
Known as the Massive Ordnance Penetrator, the enormous precision-guided bomb was developed to attack deeply buried and heavily hardened targets.
Years of intelligence work had gone into understanding Fordow’s construction, geology, ventilation system and vulnerabilities.
The United States spent roughly 15 years developing and refining the weapon and the tactics necessary to attack such a target.
When the first bombs fell that night, years of preparation were compressed into seconds.
According to Gen. Dan Caine, then chairman of the Joint Chiefs of Staff, one B-2 pilot described the detonation as the brightest explosion he had ever witnessed.
The attack was underway.
Fourteen Massive Bunker Busters Strike Iran
The B-2 force ultimately dropped 14 GBU-57 Massive Ordnance Penetrators against the Fordow and Natanz nuclear target areas.
The scale was unprecedented.
Each weapon weighs roughly 30,000 pounds and is designed to penetrate deeply into reinforced structures or earth before exploding.
The concept is fundamentally different from a conventional surface strike.
An ordinary bomb can destroy buildings, vehicles and exposed equipment.
A penetrator is intended to carry explosive power into the protected structure itself.
That capability was crucial against Iranian facilities specifically designed to survive air attack.
Fordow received the most attention because of its extreme depth and strategic importance.
Natanz, another major center of Iran’s uranium enrichment program, was also struck with the massive weapons.
Isfahan was attacked separately with Tomahawk cruise missiles targeting key surface infrastructure.
Pentagon officials later said all three sites sustained extremely severe damage and destruction.
Iran’s Air Defenses Failed to Stop the Strike
Perhaps one of the most striking aspects of Midnight Hammer was what apparently did not happen.
Iranian fighters did not intercept the B-2s.
Iranian surface-to-air missile systems did not successfully engage the American strike package.
Pentagon officials said they were unaware of any shots being fired at the force as it entered or exited Iranian airspace.
That outcome reflected far more than the stealth characteristics of the B-2.
The operation involved more than 125 U.S. aircraft, including fighters, aerial refueling tankers and intelligence, surveillance and reconnaissance platforms.
American aircraft operating ahead of the bombers were prepared to suppress Iranian air-defense systems.
Decoys and other deception tactics complicated Iran’s ability to understand what was happening.
Timing was critical.
The bombers, fighters, tankers, cruise missiles and support platforms had to operate as parts of a single synchronized attack.
A mistake could have exposed the B-2s.
Instead, the bombers released their weapons and departed.
Washington Declares a Devastating Blow
President Donald Trump announced the strikes after the operation was underway, declaring that Iran’s principal nuclear enrichment facilities had been devastated.
Defense Secretary Pete Hegseth subsequently characterized the mission as an overwhelming success.
But determining exactly what survived underground proved more complicated.
Initial Pentagon assessments described extremely severe damage at all three nuclear sites.
Later assessments and public reporting produced debate over the extent to which Iran’s overall nuclear capability had been permanently eliminated.
The Pentagon continued to maintain that the strikes had severely degraded the program and set it back substantially.
Other preliminary intelligence assessments were more cautious, particularly regarding equipment and enriched uranium that Iran might have relocated before the attack.
That uncertainty matters because destroying buildings is not necessarily the same as eliminating nuclear knowledge or nuclear material.
Iran retains scientists, technical expertise and an industrial base.
The question is how much physical infrastructure survived — and how quickly Tehran could rebuild.
A Historic Mission With Global Consequences
Midnight Hammer was significant far beyond Iran.
The attack demonstrated that the United States was willing to use strategic stealth bombers directly against some of the most sensitive targets in the Middle East.
The B-2s had traveled thousands of miles, refueled repeatedly in the air, penetrated Iranian territory, delivered enormous bunker-buster bombs and returned without a confirmed combat loss.
The operation also demonstrated the reach of American military power.
Bombers launched from the United States.
Tankers sustained them across enormous distances.
Fighters protected their route.
A submarine attacked from the sea.
Space, cyber, intelligence and command networks supported the operation.
The result was an attack conducted across multiple domains against targets buried beneath Iranian territory.
The Nuclear Question Did Not Disappear
Yet even a strike of this magnitude could not resolve the political problem surrounding Iran’s nuclear ambitions.
Buildings can be destroyed.
Tunnels can collapse.
Centrifuges can be damaged.
But nuclear expertise cannot be bombed out of existence.
That is why the aftermath of Midnight Hammer immediately shifted attention from the explosions themselves to a much harder question: what would Tehran do next?
Iran could attempt to reconstruct damaged facilities.
It could disperse sensitive nuclear equipment across smaller locations.
It could build new installations even deeper underground.
Or it could return to negotiations.
Each possibility carries enormous consequences.
The military operation therefore represented both an extraordinary tactical achievement and the beginning of a new strategic uncertainty.
The Night the B-2 Went to War Over Iran
The image of seven B-2 stealth bombers moving silently toward Iran became one of the defining images of the confrontation.
Their targets were not an alleged nuclear facility on Kharg Island.
They were the confirmed nuclear sites at Fordow, Natanz and Isfahan — facilities at the center of international concern over Iran’s nuclear program for years.
The United States had spent more than a decade preparing weapons capable of reaching some of those underground targets.
Then, in a matter of minutes, those weapons were finally used.
Fourteen Massive Ordnance Penetrators fell on Fordow and Natanz. Tomahawk missiles slammed into infrastructure at Isfahan. More than 125 American aircraft participated in the wider operation.
And before Iran could mount an effective response against the incoming bomber force, the B-2s were already leaving Iranian airspace.
Whatever the ultimate long-term impact on Tehran’s nuclear ambitions, Operation Midnight Hammer established one fact beyond dispute:
Iran had buried some of its most valuable nuclear infrastructure beneath mountains to protect it from attack.
The United States responded by bringing weapons specifically designed to reach it.
