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

The second phase of the war between the US and Iran has begun and this phase has been far more intense than the first.

In the first phase, air defense networks were crippled, electronic warfare centers were struck and naval assets in the straight of Hormuz were targeted.

The second phase, however, was different.

This time, the targets were at the heart of the underground missile empire Iran has been building for 40 years.

On the night of March 27th, 2026, four B2 Spirit stealth bombers took off from Whiteitman Air Force Base in Missouri under the cover of darkness.

Each carried the US’s heaviest conventional weapon.

The B2’s targets were critical underground facilities in the Tehran, Isvahan, and Yazd regions, as well as missile depots along the coastal strip.

The facility’s structural collapse is documented in imagery.

The fourth and perhaps most strategically urgent target was not underground, but on the coast.

A large underground storage facility near the straight of Hormuz housed a significant number of ballistic missiles, particularly anti-ship stocks threatening maritime traffic stored in high concentrations.

Iran could target tankers and commercial ships passing through the strait with the missiles in this depot.

This was the physical power behind its greatest strategic asset in decades.

and the capacity to hold 20% of global oil trade hostage depended on this depot.

According to reports, secondary detonations triggered by the GBU57 strike caused a chain reaction of fires.

The ammunition’s self-destruction may have created an unstoppable chain of explosions, potentially destroying a large portion of the stockpile.

This strike appears to have significantly weakened Iran’s ability to use the Strait of Hormuz as a weapon.

But the underground was not the only front.

A heavy toll was also exacted at sea.

The IRGC Navy’s boat fleets were targeted with precisiong guided munitions that same night.

Fast attack boats, patrol vessels, and coastal defense assets were systematically struck.

According to Sentcom data, over 150 Iranian ships or boats were damaged or destroyed during the conflict.

a figure indicating that Iran’s coastal defense capabilities have been largely neutralized.

The USS Tripoli amphibious assault ship and 3,500 Marines arrived in the area and are now ready for coastal operations.

Iran’s defense planners are forced to manage simultaneous crises on multiple fronts.

And striking wasn’t enough.

The coalition also crippled repair capabilities.

The Dezful missile base is the most striking example of this strategy.

This massive missile city in Kestan province had already collapsed in previous attacks.

While Iranian crews were clearing debris and trying to reopen roads, bulldozers were targeted by precision drone strikes.

Sentcom’s message was clear.

No repairs.

Debris removal vehicles were struck.

Transportation routes were blocked.

and the logistics chain was systematically severed.

The regime’s underground doctrine was based on the assumption that even if you’re hit, you can repair it.

Now repair equipment is also a target.

Repair personnel are at risk.

And that assumption has collapsed.

Four underground targets, naval power, and repair capacity all in a single night in a single operational flow.

The underground production complex protected by a deep tunnel system around Tehran served as the final assembly line for ballistic missile bodies.

The final stop in the serial production of Shahab and Sedil variants.

A target whose coordinates were pinpointed with millimeter precision through months of satellite surveillance and signals intelligence work by US and Israeli intelligence.

The GBU57 was dropped from high altitude, penetrated the mountains rocky structure and reinforced concrete layers, and reportedly detonated at a depth of 50 m.

It is reported that the seismic wave rendered the assembly lines inoperable, and the blast pressure also collapsed the supporting infrastructure.

It is reported that the facility’s ventilation shafts were sealed off, the electrical system was disabled, and personnel inside were forced to evacuate.

Infrastructure worth billions of dollars may have effectively collapsed from a single bomb.

Iranian teams were only able to reach the area hours later to assess the damage.

But the assembly line alone doesn’t mean much.

A missile body is useless without an engine.

The second target in Isvahan province was a rocket engine test complex, a critical center where the propulsion systems for Shahab variants were developed and where engines were tested and calibrated.

The heart of Iran’s ballistic missile program beat here.

Reports indicate that the GBU57’s explosion at a depth of 150 ft completely destroyed the equipment.

Fires disabled the ventilation system and sensitive calibration devices in the test chambers were damaged.

While the Iranian side has attempted to downplay the damage, independent satellite data paints a different picture.

The damage is assessed to be permanent and the production chain is believed to have been severed at this point.

The third strike reached the deepest point of the operation.

The GBU57’s 200 ft penetration at the underground facility processing crews missile components in the Yaz region, the deepest strike of the operation, appears to have achieved full effectiveness.

It is claimed that the thermmoaric effect triggered the facility’s oxygen system and the resulting chain reaction destroyed both the production area and the storage section.

This strike may have directly weakened Iran’s asymmetric cruise missile capability, the production source for munitions supplied to Hezbollah and the Houthis.

The Iranian Atomic Energy Organization claimed limited impact, but independent satellite data does not support this claim.

The four links of the production chain final assembly tan engine production isvahan component processing yaz and storage hormuz cannot operate independently.

Striking all four simultaneously appears to have strategically crippled Iran’s missile capabilities.

The collapse of three underground missile production facilities and the strategic dep depot in the straight of Horus signifies the severing of a production and supply chain from its central hub.

The simultaneous shutdown of different facilities where missile bodies, engines, and guidance systems are produced will create a supply bottleneck lasting months.

In military production, the process of assembling components relies on precise timing.

While the failure of even a single link can halt the entire assembly line, Operation Epic Fury shattered three key links in this chain simultaneously.

This situation leads to missile batteries on the ground running out of ammunition and ships at sea waiting without munitions.

This scenario constitutes a full-scale strategic strangle hold in military terms.

Furthermore, we see that the operation did not merely destroy existing facilities, but also paralyzed repair capabilities.

For instance, the events at the Desful Missile Base in Kusteran Province demonstrate just how methodically this strategy operates.

At this base, which had already collapsed in previous attacks, heavy machinery and bulldozers attempting to clear roads and remove debris, were struck by precision fire from drones in the air.

This action is not merely aimed at destroying a facility.

It also seeks to eliminate the opposing side’s hope of recovering, regrouping, and rebuilding.

Striking a base causes damage, but targeting the teams and vehicles sent to repair it drives the logistic system into a state of psychological helplessness.

Closed roads, the inability of aid to reach the area, and the paralysis of infrastructure eliminate the systems ability to regenerate itself.

This systematic obstruction accelerates the process of the military infrastructures collapse.

From the perspective of the home front, seismic shock waves and massive underground explosions appear to have caused a significant breakdown in perception among the civilian population and the revolutionary guards.

For decades, the Iranian state has instilled in its people and military the idea that the tunnels and shelters beneath the mountains are impenetrable.

These underground cities were presented as physical proof of the regime’s myth of invincibility.

However, the bunker busting munitions carried by B2 bombers shattered this illusion in a matter of seconds.

Seeing the mountains, which people had relied on for safety and believed to be impenetrable, transform into graves creates a deep atmosphere of panic.

The reality that even the deep shelters where command meetings are held are no longer safe fuels paranoia among the leadership.

What is gone is not just the ammunition depots but the very promise of state security itself.

Developments on the maritime front also form another pillar of the logistical strangulation strategy.

The destruction of the underground dep depot in the straight of Hormuz and the neutralization of over 150 naval vessels demonstrate how a power threatening global trade routes has been asymmetrically weakened.

The strait is one of the lifelines of global oil trade.

The ability to threaten maritime traffic here with anti-ship missiles was a significant geopolitical trump card in Iran’s hands.

The destruction of this depot means that trump card can no longer be played on the ground.

The sinking of fast attack craft and patrol vessels not only restricts the maneuvering space of naval forces, but also weakens the defense of the coastal zone.

The halting of military mobility is significantly shifting the power dynamics in the Gulf in favor of the US and its allies.

The fact that naval assets are confined to ports or cannot venture out to sea due to the fear of being struck is proof that the strangulation strategy is working at sea as well.

The air traffic management and logistical support conducted behind the scenes of all these operations are also factors amplifying the ripple effect.

The increase in the number of B1B and B-52 bombers deployed to RAF Fairford in the UK clearly indicated that this was not a routine rotation, but rather preparation for a long-term air campaign.

Rather than intercontinental
flights, concentrating long range strike forces at points closer to the targets shortens the operation’s reaction time.

This forward deployment strategy which enables the maintenance of constant pressure on the target is based on the principle of not giving the enemy a moment’s restbite.

Thanks to the refueling bridges established over the ocean by aerial refueling aircraft, the B2s were able to carry out their missions without interruption.

This massive logistical orchestration represents a power projection capability possessed by very few countries in the world and is the primary deterrent behind the physical destruction created on the ground.

The diplomatic repercussions of this destruction on the ground are also severe.

The Trump administration’s strategy is clear.

Four to six weeks of intensified conflict followed by forcing negotiations.

The goal is not to completely topple the regime, but to reduce its military capabilities to a point where returning to the negotiating table is the only option.

The White House considers this timeline unstable, and the option of a serious escalation remains on the table should talks fail, a classic example of coercive diplomacy.

Iran’s response, however, is diametrically opposed to the reality on the ground.

The regime’s six-point demand list, binding guarantees, the closure of US bases, war reparations, a regional ceasefire, a new legal regime in the Strait of Hormuz, and the extradition of individuals linked to media operations is seen as a show of strength to its domestic audience by a government whose infrastructure has collapsed and whose naval power is paralyzed.

The near zero likelihood of these demands being met signals just how arduous the diplomatic process will be.

But the true strategic impact of Epic Fury isn’t limited to Iran.

For 40 years, Iran has built massive tunnel cities beneath its mountains at a cost of billions of dollars and decades of engineering effort.

The logic behind this underground empire was simple.

Even if the surface is struck, the assets beneath the mountain will survive.

And this logic was partially correct.

Even the GBU57 cannot reach the deepest tunnels.

But the coalition did not attempt to penetrate the deepest tunnels.

Instead, it targeted production facilities, assembly lines, and storage areas.

In other words, the actual source of missile capability.

And four aircraft and seven GBU57s appear to have rendered this source largely ineffective in a single night.

This message is not just for Thran.

It’s also directed at China’s Yulin submarine base, Russia’s Yamanau Strategic Bunker, and North Korea’s tunnel networks.

Depth and distance may no longer serve as a shield.

Surgical precision was also applied on the nuclear front by striking the support infrastructure of the heavy water reactor area in Iraq.

The potential for plutonium production was cut off by targeting the yellow cake production lines in Yaz, the earliest stage of the nuclear fuel cycle.

raw material processing was halted.

While fuel rod storage areas around the bush air plant were struck, Rosatom issued a security alert and evacuated its personnel, but the reactor cores were protected and no radiation leaks were reported.

Coordination was established
with the IAEA and the issue of nuclear safety was brought to the international stage.

The nuclear cycle was severed at three points.

Raw material, plutonium, and fuel rods.

But no environmental disaster was caused.

The US message is clear.

We can contain your nuclear capabilities, but we’ll do it surgically.

This approach serves as a sophisticated deterrent demonstration to all nations on the nuclear threshold.

In conclusion, the roar of engines echoing through the night sky on March 28th was not merely a harbinger of bombs, but also the opening sound of a new era in global military balances.

Iran’s myth of invincibility hidden beneath the mountains completely collapsed alongside the seismic waves of those bunker busting munitions arriving from Missouri.

The collapse of the underground doctrine, the surgical precision with which the infrastructure surrounding nuclear facilities was severed and the paralysis of naval power demonstrated the asymmetric capabilities of modern air power to the entire world.

So how will this strategic blockade and the collapse of defense paradigms shape the military preparations of other actors? Will this process in which the cards have been reshuffled so drastically in the Middle East lead to a diplomatic solution or a deeper geopolitical fault line? We will
continue to closely monitor where events will unfold within the tight timeline set by Washington.
