Introduction
When a classified CIA assessment leaked to the Washington Post this week, it carried a message that cut against months of official triumphalism: Iran still possesses roughly 70% of its pre-war missile stockpile and about 75% of its mobile launch platforms. It can withstand the current naval blockade of the Strait of Hormuz for at least 90 to 120 days without suffering economic collapse. For those who had followed the trajectory of Iran’s missile doctrine over the past two decades, the assessment was sobering — but not surprising.
This analysis examines why Iran’s missile capabilities proved so resilient, what the CIA’s findings reveal about the limits of aerial bombardment as a coercive tool, and what the coming months may look like.
A Program Built to Survive
Iran’s missile program was not designed to win a conventional war. It was designed to survive one. The trauma of the 1980–88 Iran-Iraq War — during which Iraqi Scud attacks struck Iranian cities with near-impunity — hardened a strategic conviction inside the Islamic Revolutionary Guard Corps (IRGC): that missiles were the ultimate guarantor of the republic’s survival when air power was unavailable or inferior.
That conviction produced an architecture of deliberate redundancy. By the time the 2025–2026 conflict began, Iran had dispersed its arsenal across at least 24 known missile sites in western Iran alone, with major clusters embedded in the Zagros and Alborz mountain ranges inside vast tunnel networks that analysts have called “missile cities.” Mobile transporter-erector-launchers (TELs) — often built on modified commercial truck chassis — allowed missiles to be repositioned constantly, complicating targeting. Hardened underground silos at facilities such as Haji Abad in Hormozgan province were oriented specifically toward Gulf targets, offering protected launch capability even under sustained attack.
This was not improvisation. It was the product of decades of institutional learning.
What the Bombardment Actually Did — and Didn’t Do
The scale of the US-Israeli air campaign against Iran was historically significant. US Central Command reported striking over 13,000 targets; the Israeli military claimed approximately 4,000 additional strikes of its own. Iranian air defenses were largely neutralized within the first 24 hours, and sustained strikes targeted launcher sites, production facilities, tunnel entrances, and missile assembly complexes.
The results were real, but partial. Analysis of satellite imagery found that 77% of known tunnel entrances to underground missile facilities had been struck. Yet in multiple cases, Iranian crews were clearing rubble and restoring access within 48 hours of strikes. A subsequent intelligence assessment cited by US officials confirmed that Iran had “saved nearly all” of its underground storage infrastructure, had repaired some damaged missiles, and had begun reassembling new systems from production runs that were near completion when the war began.
The mobile launcher fleet — the TELs — proved particularly difficult to neutralize. Iran’s strategy of basing TELs on modified commercial vehicles, dispersing them among civilian infrastructure, and operating them from shifting positions in the Iranian interior made them a persistent targeting challenge. By the most credible estimates available, Iran retained approximately 75% of its pre-war mobile launcher capacity even after weeks of intensive bombardment. Launchers, it turns out, are harder to kill than missiles.
This points to a structural problem that military analysts have long identified: in a sufficiently dispersed, underground-based arsenal, “taking out the archers, not the arrows” is the right conceptual framework — but extremely difficult to execute in practice when archers move constantly and shelter deep inside mountains.
The Drone Dimension: A Threat That Outlasts the War
Perhaps the most strategically significant detail to emerge from expert assessments is not about ballistic missiles at all — it is about drones. Analysts including researchers at Tel Aviv’s Institute for National Security Studies have warned that the primary threat to Hormuz shipping may now come not from ballistic missiles but from low-cost unmanned aerial vehicles. A single drone strike on a tanker, it has been noted, may be sufficient to render maritime insurance for the strait commercially unviable, achieving the blockade effect from below rather than above.
Iran’s drone production infrastructure is substantially more dispersed and harder to target than its ballistic missile assembly lines. Shahed-class drones and their derivatives are manufactured in small facilities that can be concealed within civilian industrial zones. The cost asymmetry is brutal: a Shahed drone costs between $20,000 and $50,000 to produce; a Patriot interceptor costs roughly $4 million per shot. Iran has had years of operational experience fine-tuning this cost-imposition strategy through Houthi proxy operations in the Red Sea, and that experience now feeds directly into its own military doctrine.
Capability vs. Compliance: The Strategic Question
The CIA leak raises a question that is more important than the raw inventory numbers: even if Iran’s missile capability were degraded further, would it compel a change in Iranian behavior?
Available expert opinion is skeptical. Iran’s leadership — increasingly dominated by hardline IRGC elements following the broader political disruptions of 2025–2026 — appears to have calculated that endurance itself is a form of deterrence. An official assessment quoted in reporting on the CIA document stated that Iranian leaders “believe they can outlast US political will” and view their continued missile capacity as central to that calculation. Iran’s “mosaic defense” doctrine — semi-autonomous regional IRGC units operating with their own stockpiles and command structures — means that even successful strikes against central command nodes do not disable the system.
There is also the matter of production recovery. Israeli military intelligence assessed that, absent the current campaign, Iran would have accumulated approximately 8,000 ballistic missiles within a year and a half. The war has significantly disrupted that trajectory, but the underlying industrial base — including the solid-fuel production lines, the guidance component supply chains, and the underground assembly infrastructure — has not been eliminated. Reconstruction is expected to be slow, constrained by sanctions on raw material imports and by the targeting of surface-level production sites. But the foundation remains.
The Reliability Problem
It would be analytically incomplete to assess Iran’s missile capabilities without noting their documented limitations. Combat experience from 2024–2026 has confirmed what many analysts suspected: not all of Iran’s missile inventory performs equally. The Fattah-1 hypersonic glide vehicle and the Kheibar Shekan solid-fueled medium-range ballistic missile have demonstrated genuine precision against hardened targets. Older liquid-fueled systems, including Shahab-3 derivatives, have shown higher failure rates and lower accuracy. The shift from volume-based saturation tactics toward more targeted precision strikes — visible in Iran’s later operational phases — suggests that Tehran is increasingly aware of this disparity and is managing its higher-quality inventory conservatively.
The CIA assessment’s 70% stockpile figure, in other words, should be understood as a mixed inventory: a significant portion of genuinely capable, precision-guided systems alongside a legacy stock of older missiles of varying reliability.
Conclusion: The Enduring Logic of the Buried Arsenal
The CIA assessment, read against the full body of evidence from the 2025–2026 conflict, confirms a strategic reality that Iran’s military planners spent forty years constructing: a sufficiently dispersed, underground, mobile missile arsenal can absorb extraordinary punishment and remain operationally relevant. The program was not designed to be destroyed from the air. It was designed to survive air campaigns long enough to impose unacceptable costs on any adversary who tried.
That does not mean the damage inflicted was irrelevant — Iran’s missile production timeline has been set back by years, and the depletion of its highest-quality systems during the conflict has narrowed its precision strike options. But the claim that Iran’s military capability has been fundamentally broken is not supported by the intelligence. The buried arsenal, battered and depleted, refused to die.
The more consequential question now is whether prolonged economic pressure — through blockade, sanctions, and the broader collapse of Iran’s petroleum revenues — can achieve what aerial bombardment alone could not. The CIA’s 90–120 day estimate for economic endurance under current conditions suggests Tehran has meaningful runway. Whether it uses that runway to negotiate, rebuild, or escalate remains the central uncertainty of the moment.
