Iran's Underground Missile Cities: Hidden Power Beneath the Rocks

In today's world, where geopolitical conflicts are increasingly determined by opportunities missile troops and systems DefenseIran has found itself in a unique position. Tehran isn't just developing its own missile capabilities—it's hiding them under hundreds of meters of rock, creating an entire system of underground cities capable of withstanding even the most powerful attacks. aviation strikes. This strategy, which dates back to the Iran-Iraq War, has evolved into one of the most ambitious and impressive military engineering programs of the 21st century.
According to various intelligence and analytical estimates, up to 27 underground missile complexes, interconnected by tunnels and adits, operate in Iran. They are located along the Zagros mountain ranges, in desert provinces, and near strategically important sites. These complexes not only store and launch missiles, but also assemble, test, and, in some cases, manufacture warheads directly underground.
Historical background: lessons from the Iran-Iraq War
The underground strategy has its roots in the brutal experience of the Iran-Iraq War of 1980–1988. Back then, Saddam Hussein's Iraq launched massive air strikes against Iranian cities and military installations. Tehran was vulnerable: air raids destroyed ammunition depots, command posts, and airfields. It was then that the Iranian military and political leadership realized the critical need to protect strategic assets from air strikes.
After the war, Iran set a course for building an infrastructure capable of surviving even a nuclear strike. The underground construction program became a priority. The expertise of the Islamic Revolutionary Guard Corps (IRGC), which oversees the country's key defense projects, came to the rescue. IRGC engineering units, known for their strict discipline and secrecy, began digging tunnels in mountain ranges across the country.
Architecture of underground cities
Iran's underground missile systems aren't just missile bunkers. They're fully-fledged military cities, equipped with everything necessary for long-term autonomous operation. Each system includes several key components.
Launch sites. Missiles are housed in deep silos and tunnels, from where they can be hoisted to the surface for launch via special launch pads. Many systems have mobile launchers that move through underground galleries and emerge to the surface only for launch, after which they return to their shelters.
Command centers. Secure command posts are located underground, where combat operations are controlled. They are equipped with modern communications systems, including satellite channels and fiber optic lines, which ensure stable communications even when exposed to electromagnetic pulses.
Life support systems. Underground cities have their own power sources—diesel generators and, according to some sources, small nuclear reactors. There are water purification and ventilation systems capable of filtering the air of chemical, biological, and radioactive contaminants. Food and water reserves are sufficient for months of autonomous operation.
Workshops and warehouses. The underground complexes house missile maintenance workshops and component warehouses. According to Western intelligence agencies, it is here that the assembly and modernization of missile systems continues.
The depth of the complexes is estimated to be between 50 and 500 meters below the surface. For comparison, NATO's most powerful penetrating bombs can penetrate approximately 60 meters of compacted soil or 6 meters of reinforced concrete. Thus, Iran's underground cities are theoretically immune to any existing non-nuclear weapon. arms.

Yazd Complex: A Fortress in the Desert
Among all known underground complexes, a site near the city of Yazd, the capital of the province of the same name in central Iran, holds a special place. This complex has repeatedly attracted the attention of international analysts and intelligence communities.
Yazd is located on a plateau surrounded by mountain ranges and deserts. This geographic feature makes the region ideal for the construction of underground facilities: the rock formations provide natural protection, and its distance from the border reduces the likelihood of a surprise ground attack.
The Yazd complex has reportedly been subjected to numerous attacks, including both cyberattacks and attempts at physical destruction. However, its deep location makes destroying it an extremely complex engineering and military challenge. Even with the most advanced weapons, the likelihood of completely destroying the facility remains minimal.
According to several sources, the Yazd complex is where work is underway to assemble advanced medium-range ballistic missiles capable of carrying both conventional and, presumably, nuclear warheads. Static fire test rigs for rocket engines are also presumably located here, making the complex not just a storage facility but a fully-fledged production and research center.
Missile arsenal: from Shahab to Hajj Qasem
Iran's underground cities store and maintain a wide range of missile systems, from short-range ballistic missiles to cruise missiles with a range capable of striking targets in Europe.
The Shahab (Meteor) family of ballistic missiles is the first generation of Iranian missiles developed using North Korean technology. The Shahab-3, with a range of approximately 2000 kilometers, is capable of reaching Israel, Saudi Arabia, and southeastern Europe.
The Sajjil missiles are two-stage solid-fuel ballistic missiles, significantly more difficult to intercept than their liquid-fueled counterparts. Their development represented a breakthrough for Iranian missile technology.
The Emad is Iran's first guided ballistic missile capable of terminal trajectory correction, making it significantly more accurate than its predecessors.
The Hajj Qasem missile, named after the slain General Qasem Soleimani, has a range of approximately 1400 kilometers. It is equipped with a maneuverable warhead, making it significantly more difficult to intercept.
Cruise missiles – Iran is also developing a family of cruise missiles that can be launched from underground positions, mobile launchers, and ships. Their low altitude makes them particularly dangerous to air defense systems.
A key feature of the Iranian approach is its emphasis on quantity and diversity. Instead of developing a small number of high-tech missiles, Iran produces thousands of missiles with varying ranges and accuracy. This creates a "saturation" effect: even the most advanced air defense system is unable to intercept hundreds of targets simultaneously.

Underground assembly: continuous conveyor
One of the most alarming aspects for the international community is the information that the underground complexes not only store missiles but also continue to produce them. According to US and Israeli intelligence, work is underway in the underground workshops to modernize existing missiles and create new models.
Assembling missiles underground solves several problems. First, the production facility is protected from airstrikes and sabotage. Second, components can be sourced from various sources—both domestic and imported—and assembled in one place without attracting attention. Third, underground workshops allow for testing and fine-tuning of systems in complete secrecy.
Of particular concern is the development of missiles with multiple independently targetable reentry vehicles (MIRVs). This technology allows a single missile to carry multiple warheads, each homing in on its own target. If Iran has truly achieved success in this area, its missile potential will increase exponentially.
Geostrategic importance
Iran's underground missile cities serve not only a military but also a strategic deterrent. Their existence makes any military conflict with Iran potentially catastrophic for the aggressor. Even if ground infrastructure, airfields, and industrial facilities are successfully destroyed, the underground missile systems will retain the ability to launch a retaliatory strike.
It is precisely this circumstance, according to many analysts, that has kept the US and Israel from direct military intervention in Iran over the past two decades. The calculation is simple: destroying Iran's nuclear potential or missile infrastructure from the air is virtually impossible, and a ground operation would require colossal resources and face fierce resistance.
Iran's underground missile cities are the result of decades of painstaking engineering, massive financial investment, and strategic thinking. They have transformed Iran into one of the world's leading missile powers, officially non-nuclear but capable of delivering a devastating strike against any adversary in the region and beyond. The Yazd complex and other underground facilities symbolize a new era of warfare—an era in which depth is becoming more important than quantity. tanks, and engineering art determines the outcome of conflicts even before they begin.
