“Iran Hid Its SCUD Missiles Underground — Then U.S. Airstrikes Found Them”
Iran spent decades building underground missile complexes designed around a simple military calculation: aircraft can destroy what they can see, but weapons buried beneath mountains are much harder to eliminate.
That strategy has now been subjected to one of its toughest tests.
U.S. and Israeli air campaigns in 2026 have repeatedly struck Iranian ballistic-missile installations, including tunnel entrances, launch positions, production facilities and hardened underground storage complexes. Satellite imagery reviewed by independent analysts shows substantial damage at a number of sites, while U.S. officials have confirmed the use of specialized penetrating bombs against underground Iranian missile facilities.

But one detail in the dramatic headline requires clarification. Iran’s modern missile arsenal is not principally made up of Soviet-designed SCUDs. Although Iran historically operated missiles derived from the Scud family, its contemporary force includes domestically developed systems such as the Shahab, Fateh, Zolfaghar, Kheibar Shekan and other ballistic missiles.
The larger story, however, is very real: Iran has hidden a significant portion of its missile capability underground, and those facilities have become priority targets in the expanding air war.
Iran’s Underground Missile Strategy
For Tehran, underground storage was never simply about secrecy.
It was about survival.
Iran has spent years developing what state media often describe as “missile cities,” enormous subterranean installations built beneath mountains or deep underground.
Inside such complexes, military forces can potentially store missiles, transporter-launchers, support vehicles, fuel, maintenance equipment and command infrastructure.
Some installations contain networks of tunnels rather than a single bunker.
The concept is straightforward.
An enemy might dominate the skies, but that does not necessarily mean it can destroy everything underneath them.
Iran’s limited conventional air power has made ballistic missiles particularly important to its defense strategy. The Congressional Research Service noted in March that Iran possessed a large inventory of short- and medium-range ballistic missiles and that American and Israeli aircraft had been attacking facilities associated with that arsenal, including missiles potentially stored underground.
Iran’s underground infrastructure was designed to make those weapons extremely difficult to destroy in a first strike.
The missiles could remain concealed until needed.
Then launchers could emerge from tunnel entrances, move to prepared positions, fire and potentially return underground.
That concept creates a major targeting problem.
Destroying a missile launcher sitting in the open is comparatively straightforward.
Destroying an unknown number of missiles hidden hundreds of feet inside a mountain is not.
American Airstrikes Went After the Tunnels
The U.S.-Israeli campaign has increasingly focused on solving precisely that problem.
Satellite analysis published in March showed strikes against Iranian underground ballistic-missile installations and tunnel entrances. The New York Times reported that U.S. Central Command had used B-2 stealth bombers carrying penetrating weapons against hardened ballistic-missile facilities.
Other attacks targeted access points.
This represents an important distinction.
An attacker does not necessarily have to destroy every missile inside a mountain to neutralize the facility temporarily.
If tunnel entrances collapse, launch vehicles may become trapped underground.
If power systems are destroyed, internal operations can be disrupted.
If communications are severed, commanders may struggle to coordinate launches.
If roads outside the facility are cratered, vehicles emerging from tunnels can become vulnerable.
The Institute for the Study of War’s Critical Threats Project reported in April that U.S.-Israeli forces had struck multiple underground missile facilities and numerous tunnel entrances. The purpose was at least partly to prevent Iranian launchers from moving out of their protected shelters.
In other words, the objective was not always to reach every missile.
Sometimes the mountain itself could be turned into a prison.
Then Came the Bunker-Busting Weapons
For deeper targets, the United States brought specialized weapons.
On March 19, U.S. military officials confirmed that American forces had employed 5,000-pound penetrating bombs against underground Iranian storage facilities containing coastal-defense cruise missiles and associated equipment.
The weapon identified was the GBU-72 Advanced 5K Penetrator, designed to penetrate reinforced concrete or rock before detonating.
That capability changes the equation.
A conventional bomb exploding on the surface transfers only part of its destructive energy underground.
A penetrator is designed to continue traveling through the surface before exploding.
The objective is to place the detonation closer to the protected structure.
Even when the weapon does not physically reach the deepest chamber, the resulting shock can damage tunnels, collapse entrances, destroy ventilation systems and make sections of a facility unusable.
For Iranian engineers, this produces an escalating contest.
Build deeper.
Reinforce entrances.
Create more tunnels.
Construct alternative exits.
Disperse equipment.
Then the attacker attempts to identify those improvements and select a weapon capable of defeating them.
Satellite Images Revealed the Damage
The battle underground has increasingly become visible from space.
A Washington Post analysis published in March examined satellite imagery showing damage to four major Iranian ballistic-missile manufacturing locations and at least 29 ballistic-missile launch sites during the opening weeks of the campaign.
Some images showed damage around tunnel entrances.
Others showed destroyed structures or changes at launch facilities.
This is where modern satellite surveillance has fundamentally altered warfare.
A mountain can conceal what is inside.
It cannot easily conceal everything happening outside.
Heavy vehicles leave tracks.
New roads appear.
Excavated soil changes the landscape.
Ventilation infrastructure can reveal underground construction.
Repeated military traffic can indicate which entrances remain operational.
After an attack, satellite imagery can identify collapsed portals, fresh craters, burn marks and subsequent excavation.
Analysts can then watch the repair effort.
That has become especially important in Iran.
The Missiles Were Damaged, But Not Eliminated
This is where the story becomes more complicated than the dramatic headline suggests.
American and Israeli forces found and struck many Iranian missile facilities.
They did not eliminate Iran’s missile arsenal.
By June, reports based on satellite imagery indicated that Iran had reopened dozens of tunnel entrances damaged during earlier attacks.
One analysis found that access had reportedly been restored to 50 of 69 tunnel entrances at 18 underground missile locations.
Iranian missiles continued to be launched despite sustained bombardment.
Reporting from the underground missile complex near Yazd described weeks of attacks against the mountainous area while Iranian forces continued firing missiles. Analysts said Iran operates dozens of underground missile installations and that deeper facilities inside the country are particularly difficult to suppress continuously.
That reveals the central weakness of airpower against underground infrastructure.
Bombing can close a tunnel.
Engineers can sometimes reopen it.
Bombing can destroy a launcher.
Another may remain inside.
Bombing can damage a missile factory.
Stored components may exist elsewhere.
A successful strike therefore does not necessarily equal permanent destruction.
Iran Began Digging Its Way Back Out
After the first major waves of strikes, Iranian recovery teams moved rapidly.
Satellite imagery showed bulldozers, loaders and other equipment clearing debris from tunnel entrances.
Roads were repaired.
Access points were reopened.
Some damaged military installations began showing renewed activity.
More recent satellite reporting indicates Iran has continued rebuilding missile bases and other military infrastructure at considerable speed.
That creates a frustrating cycle for the attacking force.
A tunnel entrance is identified.
It is bombed.
Iran clears the rubble.
The entrance becomes operational.
It is targeted again.
Maintaining suppression therefore requires persistent surveillance and repeated attacks.
And that becomes expensive.
Aircraft require maintenance.
Precision weapons are finite.
Pilots require rest.
Tankers must provide fuel.
Intelligence systems must constantly monitor targets.
Air defenses must protect American and allied installations from Iranian retaliation.
The question eventually becomes not merely whether underground missile sites can be attacked, but whether they can be kept disabled indefinitely.
Iran’s Missile Force Remains Dangerous
Despite the destruction, Iran has demonstrated that its ballistic-missile capability remains operational.
Recent reporting indicates Tehran continues to possess and employ sophisticated systems from its underground missile infrastructure.
That includes systems such as the Kheibar Shekan, alongside other solid-fuel and guided ballistic missiles.
Iran’s ability to continue launching weapons after extensive bombardment demonstrates why the underground network was built in the first place.
Redundancy is part of the strategy.
One base can be damaged.
Another can continue operating.
One entrance can collapse.
Another may remain accessible.
One missile production line can be destroyed.
Existing stockpiles can still be used.
The network does not need to remain completely intact to remain strategically relevant.
It only needs enough surviving weapons and launchers to impose costs on an adversary.
Why Calling Them “SCUDs” Can Be Misleading
The term SCUD has become shorthand in popular discussion for almost any large ballistic missile.
Technically, that is inaccurate.
The original Scud was a Soviet-designed short-range ballistic missile that proliferated widely during the Cold War.
Iran obtained Scud-type missiles during the Iran-Iraq War and subsequently developed systems influenced by foreign missile technology.
The Shahab-1, for example, is closely associated with the Scud-B lineage.
But Iran’s missile program evolved substantially beyond those early systems.
Its modern inventory includes weapons with greater range, improved guidance, different propulsion systems and substantially different operational characteristics.
So while “SCUD missiles underground” creates a dramatic image, the more accurate description is Iranian ballistic and cruise missiles stored in hardened underground complexes.
That distinction matters when assessing what U.S. airstrikes are actually targeting.
Washington Is Trying to Break the Missile Cycle
The broader American objective appears to extend beyond destroying individual missiles.
It involves disrupting the entire chain required to launch them.
That means attacking storage.
Production.
Command facilities.
Launchers.
Radar.
Communications.
Road access.
Tunnel entrances.
Support equipment.
By late July, U.S. strikes were still targeting Iranian missile and drone facilities as part of retaliatory operations. Reuters reported that an American two-hour strike wave hit dozens of IRGC targets, including missile facilities, command centers, maritime-defense sites and other infrastructure.
This is essentially an attempt to dismantle the ecosystem surrounding the missile.
A ballistic missile without a functioning launcher is useless.
A launcher trapped underground cannot fire.
A launcher without targeting information is less effective.
A missile unit without communications may struggle to coordinate attacks.
A factory without specialized machinery cannot quickly replenish losses.
Each strike therefore attacks one part of the system.
But Iran Is Learning Too
Tehran is not passively absorbing the attacks.
Its forces have adapted.
Facilities have been repaired.
Infrastructure has been rebuilt.
Missiles have been dispersed.
Underground complexes continue to play a role.
Iran has also demonstrated the ability to keep launching sophisticated weapons despite months of attacks, complicating earlier predictions that sustained airpower would rapidly neutralize its missile force.
This has become a contest between surveillance and concealment.
Between penetration and fortification.
Between destruction and reconstruction.
The United States attempts to locate tunnel entrances.
Iran attempts to disguise or multiply them.
American aircraft attack launch infrastructure.
Iran repairs it.
Surveillance aircraft and satellites watch movement.
Iranian units attempt to move during periods when they believe observation is weakest.
Neither side remains static.
Underground Does Not Mean Invisible
One of the biggest lessons emerging from the campaign is that underground facilities are extremely difficult to destroy, but they are not necessarily impossible to locate.
A missile complex requires connections to the surface.
Personnel must enter.
Equipment must move.
Electricity and ventilation are needed.
Launch vehicles require roads.
Missiles eventually have to leave their shelters if they are going to be fired from mobile launchers.
Every one of those activities creates opportunities for detection.
That is where persistent surveillance becomes critical.
The attacker may not know exactly what is stored deep inside a mountain.
But it can watch the doors.
And once a launcher emerges, the protection offered by hundreds of feet of rock disappears.
The War Beneath the Mountains Is Far From Over
The headline suggests a simple story.
Iran hid its missiles.
America found them.
America destroyed them.
Reality is considerably more complicated.
Iran did build an enormous underground missile infrastructure.
U.S. and Israeli forces have located and attacked significant parts of it.
Satellite imagery confirms widespread damage.
American forces have used specialized penetrating bombs against underground weapons facilities.
Tunnel entrances have been repeatedly destroyed.
But Iran has also repeatedly reopened damaged sites.
Many missiles appear to have survived.
Some underground complexes remain operational.
And Tehran continues rebuilding.
That makes the campaign less a single devastating discovery than a prolonged struggle over whether airpower can permanently suppress a missile force specifically designed to survive aerial attack.
The mountains gave Iran protection.
Modern surveillance exposed the entrances.
Penetrating bombs gave Washington a way to attack deeper targets.
Iranian engineers then began digging their way back out.
And months into the confrontation, that cycle continues.
The real strategic question is therefore no longer whether American aircraft can find Iran’s underground missile infrastructure. Evidence shows that many of those sites have already been identified and repeatedly attacked.
The far harder question is whether the United States can destroy enough of that infrastructure, often enough and for long enough, to prevent Iran from continuing to launch missiles.
So far, the answer remains uncertain.
Iran’s underground arsenal has been battered, tunnel entrances have collapsed and production sites have suffered serious damage.
But beneath Iran’s mountains, enough of the missile network appears to have survived to ensure that the battle is not over.
