Iran has resumed assembling ballistic missiles inside deeply buried underground facilities, utilizing stockpiled components to circumvent the heavy military infrastructure damage inflicted by prior U.S. and Israeli airstrikes. This development directly challenges official declarations from Western capitals that Tehran's strategic missile capabilities were permanently dismantled during previous military campaigns.
Intelligence shared by American and Middle Eastern officials paints a picture of a state adjusting its survival mechanics. The Islamic Revolutionary Guard Corps is not building massive, surface-level manufacturing plants vulnerable to precision munitions. Instead, engineers are operating out of fortified subterranean networks like the sprawling complex at Khojir, piecing together both liquid-propellant and solid-propellant systems from pre-existing frames, guidance units, and warheads.

For years, defense analysts warned about the architectural philosophy governing Iran’s military industrial complex. It was never centralized enough to be erased by a single week of bombing.
The Illusion of Decisive Destruction
When defense ministries announce that an adversary's missile program has been effectively neutralized, political expediency usually outweighs tactical reality. Pentagon statements following previous intensive exchanges claimed that up to ninety percent of Iran's industrial base for producing ballistic weapons had been wiped out. To explore the full picture, check out the excellent article by The Guardian.
That assessment contained a fundamental flaw. It conflated the destruction of visible assembly buildings with the total elimination of the underlying supply chain.
Long before the first wave of retaliatory airstrikes hit, military planners in Tehran anticipated attrition. They practiced distributed manufacturing. They buried component production lines beneath mountains and prepositioned stocks of airframes, computer guidance cards, and rocket motor casings across hidden depots. When the surface structures collapsed, the inventory hidden below remained intact.
Consider a hypothetical equivalent in commercial manufacturing. If a primary automotive plant burns down, observers assume production halts. But if the company has already warehoused thousands of chassis, engines, and microchips in secure regional bunkers, assembly can restart in local garages long before a new factory is ever built. Iran applied this exact logic on a national scale.
The current re-assembly effort operates at a lower volume than its pre-war peak, restricted by a lack of specialized industrial mixers for solid fuel and destroyed chemical processing units. Yet, low-volume assembly is enough to replenish depleted stockpiles faster than interceptor missiles can be economically manufactured by Washington's allies.
The Attrition Trap
A quiet financial and industrial war of attrition now defines the region. Interceptor batteries deployed by the United States and its Gulf partners cost millions of dollars per unit. Simple ballistic missiles built from stockpiled components underground cost a fraction of that to piece together.
Tehran understands this mathematical asymmetry. Every missile reassembled in an underground vault forces the deployment of multi-million-dollar defense assets.
Regional officials point out that certain elements remain difficult to replace over the short term. Advanced chemical precursors required for high-grade solid rocket propellant and specialized metal-alloy casings cannot easily be fabricated locally once dedicated industrial plants are flattened. However, open borders and clandestine maritime smuggling networks continue to bleed foreign-sourced components through third-party intermediaries.
Defense intelligence analysts who track proliferation networks note that sanctions compliance enforcement has structural blind spots. Dual-use electronics, telemetry equipment, and precision machinery routinely flow through secondary shipping hubs in Asia and the Middle East, masquerading as commercial industrial goods. By the time intelligence agencies flag a shipment, the critical microprocessors are already sealed inside a missile guidance bay deep beneath the Iranian plateau.
The Limits of Air Power
Air campaigns possess extraordinary utility for breaking fixed targets, but they struggle against deeply buried, mobile, and decentralized networks. Dropping heavy ordnance on a mountain bunker can cave in an entrance, but if the internal tunneling system spans multiple kilometers with reinforced blast doors and independent power generators, the facility remains operational.
This structural reality exposes the widening gap between strategic messaging and operational ground truth. Declaring an adversary's missile threat solved provides short-term political comfort, but it creates strategic vulnerability.
The resumption of ballistic missile assembly inside subterranean complexes demonstrates that deterrence cannot rely purely on punitive strikes. Physical destruction of hardware acts merely as a temporary tax on an adversary's timeline, not a permanent termination of capability. As long as the intellectual capital, blueprints, and scattered component stockpiles survive beneath the earth, the machinery of war will continue to turn in the dark.
