Hormuz Strait Tunnels of Iran Have Been COLLAPSED! Hundreds of Coastal Missiles Stuck in Tunnels

Iran’s Underground Missile Empire Crumbles Under Relentless U.S. Assault

The war over the Strait of Hormuz has entered a terrifying new chapter. What began as a campaign to contain maritime threats and protect global shipping lanes has now transformed into a full-scale assault on the hidden military infrastructure that Iran spent decades building beneath its mountains. Across the deserts and rocky terrain of Iran, underground missile tunnels once believed to be untouchable are collapsing under the force of precision bunker-busting strikes, while coastal missile depots erupt in massive secondary explosions visible from space.

For years, Tehran proudly showcased its vast underground “missile cities” as symbols of invulnerability. These tunnels, buried deep inside mountains and reinforced with layers of concrete and rock, were designed to guarantee that Iran could continue launching missiles even during wartime. State television frequently displayed images of endless corridors lined with ballistic missiles, underground launch rails, and heavily fortified command centers. The message was clear: Iran’s strategic arsenal could survive anything.

But now, that myth appears to be collapsing alongside the tunnels themselves.

Operation Epic Fury Begins

According to multiple military sources, the second phase of the U.S.-led campaign—known as Operation Epic Fury—was launched during the night of March 27th, 2026. Unlike the earlier phase of the conflict, which focused on disabling radar systems, electronic warfare centers, and naval assets near the Strait of Hormuz, this new operation aimed directly at the core of Iran’s missile production and storage network.

Shortly after midnight, four B-2 Spirit stealth bombers reportedly departed from Whiteman Air Force Base carrying America’s most powerful conventional bunker-busting weapon: the GBU-57 Massive Ordnance Penetrator.

Each bomber flew under heavy operational secrecy across thousands of miles before approaching Iranian airspace. Their targets were among the most heavily fortified military sites in the Middle East—facilities buried beneath mountains in the Tehran, Isfahan, and Yazd regions, along with a massive missile storage complex near the Strait of Hormuz itself.

Military analysts say the objective was not merely to damage Iran’s missile arsenal, but to sever the entire production chain from beginning to end.

Mountains Turn Into Graves

The first strike reportedly hit an underground missile assembly complex near Tehran. Intelligence gathered through months of satellite surveillance and electronic interception had identified the site as one of the final assembly lines for Shahab and Sejjil ballistic missile variants.

The GBU-57 penetrator bomb slammed through layers of reinforced rock and concrete before detonating deep underground. The resulting seismic shockwave is believed to have collapsed internal tunnel sections, destroyed ventilation systems, and rendered assembly lines inoperable.

Satellite imagery released afterward appeared to show large sections of mountain terrain caving inward. Emergency crews arriving at the site reportedly struggled to access the tunnels because entrances had either collapsed or were engulfed in fire and smoke.

Witnesses in nearby towns described hearing what sounded like an earthquake.

“It felt like the mountain exploded from inside,” one resident reportedly said in local footage circulating online.

The psychological impact may be as significant as the physical destruction. For decades, Iran’s underground facilities represented security, resilience, and strategic deterrence. Now, those same tunnels are becoming symbols of vulnerability and fear.

The Heart of the Missile Program Hit

The second major strike targeted a rocket engine testing and calibration center in Isfahan province. Western intelligence agencies have long considered this facility a critical component of Iran’s ballistic missile program.

According to defense reports, the underground chambers housed propulsion testing equipment used to develop engines for long-range missiles. The site also contained sensitive calibration systems necessary for maintaining missile accuracy and reliability.

When the bunker-busting munition detonated beneath the facility, fires reportedly spread through ventilation shafts and technical chambers. Analysts believe the blast destroyed specialized machinery that cannot be easily replaced under international sanctions.

This matters because missile production is not simply about manufacturing metal casings. Without functioning propulsion systems and engine calibration, entire missile lines become unusable.

Military experts describe this strike as equivalent to destroying the “heart” of Iran’s missile infrastructure.

Deepest Strike Reaches Yazd

Perhaps the most dramatic attack occurred in the Yazd region, where another underground facility allegedly processed cruise missile components and guidance systems.

Reports suggest the bomb penetrated nearly 200 feet underground before detonating. The explosion is believed to have triggered a thermobaric chain reaction inside oxygen-rich sections of the tunnel network, creating devastating internal pressure waves.

Sources claim both production halls and storage sections were annihilated in the blast.

This strike could have enormous implications beyond Iran itself. Intelligence officials believe facilities in Yazd played a role in producing components for cruise missiles supplied to proxy groups such as Hezbollah and the Houthis.

If true, the destruction may weaken Iran’s ability to project power through allied militias across the region.

Hormuz Missile Depot Engulfed in Fire

While the underground facilities drew most of the attention, another strike near the Strait of Hormuz may prove equally important strategically.

A vast coastal missile depot reportedly stored large quantities of anti-ship ballistic missiles and cruise missiles intended to threaten commercial shipping routes through the strait.

These weapons formed the backbone of Iran’s long-standing strategy of controlling maritime traffic through intimidation and disruption. Roughly 20% of the world’s oil trade passes through the Strait of Hormuz, making the area one of the most important energy chokepoints on Earth.

The bunker-busting strike triggered massive secondary explosions that reportedly continued for hours. Videos circulating online showed giant fireballs erupting from the coastal mountainside as stored ammunition detonated sequentially.

Military analysts believe the destruction of this depot could severely weaken Iran’s ability to threaten tankers and international shipping.

For years, Tehran relied on the possibility of closing Hormuz as one of its strongest geopolitical bargaining chips. Now, that leverage may be slipping away.

Iran’s Navy Suffers Devastating Losses

The underground campaign was accompanied by a parallel assault on Iranian naval assets.

According to reports from U.S. Central Command, more than 150 Iranian boats and vessels have been damaged or destroyed since the conflict intensified. Fast attack craft, patrol boats, and coastal defense systems were systematically targeted using precision-guided munitions.

The campaign focused heavily on the naval forces of the Islamic Revolutionary Guard Corps, which has long specialized in asymmetric maritime warfare.

For years, Iran’s strategy relied on swarms of small, fast boats capable of harassing larger warships and threatening commercial tankers. These vessels were difficult to detect and could overwhelm defenses through sheer numbers.

But against modern surveillance systems, drones, and precision airpower, the tactic appears to be failing catastrophically.

The arrival of the USS Tripoli carrying thousands of Marines further increased pressure on Iran’s coastal defenses. Military planners now believe coalition forces possess overwhelming dominance at sea.

Repair Crews Become Targets

One of the most controversial aspects of the campaign has been the targeting of repair operations.

At the Dezful missile base in Khuzestan province, drone strikes reportedly hit bulldozers and debris-clearing vehicles attempting to reopen collapsed access roads.

The message was unmistakable: rebuilding efforts would not be allowed to proceed.

Military strategists say this reflects a broader doctrine focused not just on destruction, but on preventing recovery. By targeting logistics, repair equipment, and transportation infrastructure, coalition forces are attempting to ensure that damaged facilities remain unusable for extended periods.

This approach creates enormous psychological strain on military personnel.

A destroyed base can theoretically be rebuilt. But when repair crews themselves become targets, the entire system begins to break down from fear and exhaustion.

Panic Spreads Through Iran

Inside Iran, reports suggest growing anxiety among both civilians and Revolutionary Guard personnel.

For decades, the regime promoted its underground tunnel network as an impenetrable shield against foreign attack. State media frequently emphasized that even if surface infrastructure were destroyed, the “missile cities” hidden beneath mountains would survive.

The latest strikes shattered that perception almost overnight.

Images of collapsed tunnels and burning underground depots are reportedly spreading rapidly through social media despite internet restrictions. Civilians near affected regions described hearing massive explosions and feeling prolonged tremors.

The psychological effect of bunker-busting bombs may be even more significant than their military impact. The realization that even deep underground shelters are vulnerable has reportedly fueled paranoia within sections of Iran’s leadership.

Security experts say the collapse of perceived invincibility can destabilize command structures as much as physical losses themselves.

Oil Markets React Instantly

The military escalation immediately sent shockwaves through global energy markets.

The Strait of Hormuz remains one of the world’s most critical maritime corridors. Any threat to shipping in the region can cause dramatic increases in oil prices within hours.

Following reports of the missile depot destruction and intensified fighting, Brent crude prices surged sharply as traders feared broader disruption to Gulf exports.

Insurance costs for commercial vessels operating near Hormuz also reportedly skyrocketed, with some shipping companies temporarily suspending transit operations altogether.

The crisis highlights how regional warfare in the Gulf rapidly affects economies worldwide. Increased fuel costs impact transportation, manufacturing, food prices, and inflation across Europe, Asia, and beyond.

In many ways, the battle for Hormuz is not just about territory or military dominance—it is about control over the arteries of the global economy.

Strategic Message to the World

Analysts believe the operation carries implications far beyond Iran.

For decades, underground military facilities have been considered one of the most reliable forms of strategic protection. Nations such as China, Russia, and North Korea all maintain extensive underground bunker networks designed to preserve military capabilities during war.

The apparent success of deep-penetration strikes against Iranian tunnel systems sends a powerful message: depth alone may no longer guarantee safety.

Military observers say the campaign demonstrates a new era of precision warfare in which satellite intelligence, stealth aircraft, and bunker-busting munitions can systematically dismantle even heavily fortified infrastructure.

Nuclear Infrastructure Also Targeted

The operation reportedly extended into parts of Iran’s nuclear support network as well.

Rather than striking active reactor cores—which could risk radioactive contamination—coalition forces allegedly targeted supporting infrastructure tied to uranium processing and fuel preparation.

Facilities associated with yellowcake processing and fuel rod storage were reportedly hit in carefully calibrated attacks intended to disrupt nuclear capability without triggering environmental disaster.

According to officials, international coordination with the International Atomic Energy Agency helped monitor nuclear safety conditions following the strikes.

No radiation leaks were reported.

The message from Washington appears carefully calculated: Iran’s strategic capabilities can be degraded surgically, without crossing the threshold into uncontrolled catastrophe.

Diplomacy or Wider War?

Despite the scale of destruction, officials insist the campaign’s ultimate goal is coercive diplomacy rather than regime change.

Sources close to the White House describe a strategy centered on several weeks of overwhelming military pressure followed by renewed negotiations.

But the danger of escalation remains enormous.

Iran has already issued sweeping demands including security guarantees, closure of U.S. bases in the region, and compensation for wartime damages. Meanwhile, regional allies are preparing for possible retaliation against shipping lanes, oil facilities, and military bases.

The presence of additional long-range bombers at RAF Fairford suggests coalition planners are preparing for a potentially prolonged campaign.

Every day the conflict continues increases the risk of broader regional confrontation involving Gulf states, proxy militias, and global powers.

The End of the Underground Illusion

In the end, the most significant development may not be the destruction of any single facility, ship, or missile battery.

It is the collapse of an idea.

For forty years, Iran’s military doctrine rested heavily on the belief that underground fortifications could guarantee survival against superior airpower. Entire strategic concepts were built around the assumption that tunnels hidden beneath mountains would remain operational no matter how intense the bombardment above.

Now, those assumptions are being rewritten in real time.

The roar of stealth bombers over the Middle East was more than the sound of another military operation. It marked the arrival of a new strategic reality—one in which precision, intelligence, and sustained pressure can dismantle even the deepest underground empires.

Whether this campaign ultimately forces negotiations or drives the region into a wider war remains uncertain.

But one thing is already clear:

The mountains of Iran no longer look invincible.
