7 MINUTES AGO! Iran’s underground ballistic missile base tunnel destroyed by B-2 bomber!
U.S. B-2 Stealth Bombers Hammer Iran’s Underground Ballistic Missile Facilities in Major Deep-Strike Operation
TEHRAN — American B-2 Spirit stealth bombers struck hardened Iranian ballistic missile facilities buried beneath mountainous terrain, unleashing heavy precision weapons against a network designed to protect some of Tehran’s most dangerous military assets from aerial attack.
The operation marked a dramatic expansion of American airpower against Iran’s missile infrastructure and demonstrated Washington’s ability to send strategic bombers deep into contested airspace to attack targets concealed underground.
U.S. Central Command confirmed on March 1 that B-2 stealth bombers armed with 2,000-pound bombs had struck hardened Iranian ballistic missile facilities.
Subsequent reporting and commercial satellite imagery indicated that entrances to some of the underground missile caves had been collapsed.
The targets were not ordinary military warehouses.

Iran has spent years constructing underground complexes capable of concealing ballistic missiles, transporter-launchers and supporting equipment beneath mountains. Some facilities are believed to include launch positions allowing missiles to be moved rapidly into firing locations while remaining protected for much of the preparation process.
For American military planners, destroying or sealing those underground networks could directly affect Iran’s ability to sustain missile attacks.
And that made the B-2 an especially important weapon.
B-2s Enter the Fight
The B-2 Spirit is one of the most sophisticated strategic bombers ever built.
Its distinctive flying-wing design and low-observable technology were developed to allow the aircraft to penetrate heavily defended airspace while carrying large quantities of precision-guided weapons.
Unlike shorter-range tactical fighters, B-2s can conduct extraordinarily long missions with aerial refueling, allowing them to strike targets thousands of miles from their home bases.
During the Iran operation, B-2s flew long-range missions before attacking hardened ballistic missile facilities.
The decision to use the aircraft carried an unmistakable message.
Washington was no longer limiting its campaign to exposed missile launchers, radar installations or conventional military buildings.
It was going after the infrastructure Iran had deliberately placed beneath rock and earth.
Those underground facilities had been built precisely because Tehran understood the vulnerability of conventional above-ground bases.
Now they were under attack.
Inside Iran’s Underground “Missile Cities”
Iran has publicly displayed portions of its underground missile network for years.
Videos released by Iranian authorities have shown long tunnels filled with ballistic missiles, transporter vehicles and other equipment.
The complexes are sometimes referred to as “missile cities.”
Their strategic purpose is straightforward.
A missile sitting on an exposed launch pad can be detected by satellites, drones or reconnaissance aircraft and attacked before it fires.
A missile hidden hundreds of feet inside a mountain is far more difficult to locate and destroy.
Underground storage also allows Iran to protect large numbers of weapons from the opening stages of an enemy air campaign.
When commanders decide to attack, launch vehicles can move through tunnels toward prepared exits or firing locations.
Some underground facilities have reportedly been designed with launch capabilities incorporated into the complexes themselves.
That creates an enormous targeting challenge.
Destroying the mountain is unnecessary if attackers can instead destroy tunnel entrances, ventilation systems, command nodes or other critical access points.
A sufficiently powerful strike can potentially collapse sections of a tunnel or trap equipment inside.
Satellite Images Reveal Damage
Evidence emerging after the B-2 missions indicated that the attacks had caused visible damage to entrances associated with Iranian missile caves.
Satellite imagery reviewed by defense analysts showed collapsed or damaged access points at some facilities.
The full condition of structures located deep underground was much harder to determine.
That distinction is important.
A tunnel entrance can appear devastated while deeper chambers remain intact. Conversely, blast pressure traveling through enclosed underground spaces can cause severe internal damage that is almost invisible from the surface.
Battle-damage assessment therefore becomes particularly complicated when the target is buried inside a mountain.
Still, blocking access to an underground missile complex can have substantial military value even if every weapon inside is not destroyed.
Missiles that cannot be transported outside cannot easily be launched.
Vehicles trapped underground cannot be repositioned.
Damaged electrical, ventilation and communications systems can make sections of a facility unusable.
Repair crews must then operate around damaged entrances that could themselves become targets in another attack.
The Battle Against Iran’s Ballistic Missiles
The B-2 strikes formed part of a much broader campaign against Iran’s ballistic missile capability.
Iran’s missile arsenal has long been central to its military strategy.
Because Tehran cannot match the United States in conventional airpower, ballistic missiles provide another way to threaten military bases and strategic infrastructure across the region.
That makes the missile network one of the highest-priority target sets for opposing forces.
A Washington Post examination of satellite imagery published later in March found extensive damage across Iranian missile infrastructure following weeks of American and Israeli strikes.
The newspaper identified damage at four important ballistic missile manufacturing locations and at least 29 launch sites.
Tunnel entrances were among the structures hit.
The scale of those attacks indicated that the objective extended beyond destroying missiles already prepared for launch.
The campaign was increasingly aimed at the entire system required to maintain Iran’s missile arsenal — production, storage, transportation and launch infrastructure.
Why Underground Bases Are So Difficult to Destroy
Mountains provide enormous natural protection.
Layers of rock can absorb or redirect explosive energy, while deeply buried tunnels are largely immune to many conventional weapons.
Iran has taken advantage of its mountainous geography by constructing military facilities underground.
That presents American planners with a difficult choice.
They can attack entrances repeatedly, attempting to seal equipment inside, or employ specialized penetrator weapons against particularly important hardened structures.
The United States possesses weapons designed specifically for this type of mission.
The B-2 is uniquely important because it combines a large weapons payload, intercontinental range and stealth characteristics.
It previously demonstrated that capability in the June 2025 American attack on Iranian nuclear facilities.
During Operation Midnight Hammer, seven B-2 bombers participated in the strike package. Six dropped 12 massive GBU-57 penetrator bombs against Fordow, while another aircraft attacked Natanz.
The March 2026 missions demonstrated that B-2s could also be employed against Iran’s ballistic missile infrastructure.
Iran Begins Repairing the Damage
Destroying a tunnel entrance, however, does not necessarily eliminate an underground complex permanently.
Iran has been working to repair portions of its damaged military infrastructure.
Satellite imagery reported during the summer showed reconstruction activity at underground missile locations, including repaired entrances and access roads.
That effort illustrates the central challenge facing both sides.
The United States and its allies can attack Iran’s missile infrastructure.
Iran can attempt to rebuild it.
The attackers can return.
Iran can move equipment deeper underground, construct alternative entrances or disperse its missile inventory.
The result is an expensive contest between destruction and reconstruction.
For Tehran, the underground network remains valuable precisely because even a damaged facility can potentially be restored.
For Washington, that means a single successful strike may not be enough.
A Strategic Message From the United States
Beyond the physical destruction, sending B-2 bombers against underground missile facilities delivered a broader strategic warning.
Iran had invested heavily in hardened bases partly on the assumption that burying weapons beneath mountains would dramatically increase their survivability.
The B-2 missions challenged that assumption.
Even if an underground facility survives internally, the United States can potentially attack its entrances, command infrastructure and surrounding support network.
Repeated strikes could gradually reduce its usefulness.
The operation also demonstrated that American strategic bombers could participate directly in the campaign while tactical aircraft attacked other targets.
That combination puts pressure on Iranian defenses.
Air-defense operators must search for stealth aircraft while simultaneously confronting cruise missiles, drones and conventional fighters.
Commanders must decide which sites receive the strongest protection.
And every missile base that remains active becomes a potential target for another strike.
The Underground War Is Far From Over
Months after the first major B-2 attacks on Iran’s hardened missile infrastructure, the battle over those facilities continues.
Iran has demonstrated an ability to repair damaged sites, while U.S. and allied strikes have demonstrated that underground construction does not guarantee immunity.
That is why the March B-2 attack remains one of the most important episodes of the air campaign.
It brought America’s premier stealth bomber directly into the effort to dismantle Iran’s ballistic missile network.
It showed that tunnel entrances and hardened facilities buried beneath mountains could be attacked.
And it forced Tehran to confront a troubling reality: the underground missile complexes designed to preserve its retaliatory power had themselves become major targets.
The entrances may be buried beneath mountains and reinforced by concrete and rock.
But in the expanding contest between Iranian missiles and American airpower, even the underground battlefield is no longer beyond reach.
