Within the first 36 hours of the joint US-Israeli military operation against Iran that began on February 28, 2026, coalition forces unleashed more than 3,000 munitions targeting the backbone of Iran’s ballistic missile program. The two most critical production sites — Parchin, southeast of Tehran, and Shahrud in north-central Iran — were struck by Israeli Air Force jets and American B-1 and B-2 bombers, destroying factories that manufactured explosive warhead materials, missile engine components, and solid propellant. By March 3, approximately 300 Iranian missile launchers had been destroyed or disabled, and Iran’s theater ballistic missile launches had dropped 86 percent from the first day of the conflict, according to Chairman of the Joint Chiefs General Dan Caine. The title’s claim that Iran’s “entire” production chain was targeted in the first 12 hours requires some qualification.
The initial phase of airstrikes prioritized roughly 200 Iranian air defense systems, not missile factories. It took approximately 24 hours to establish effective control of airspace from western Iran to central Tehran, after which deeper strikes on production infrastructure became feasible. The major hits on Parchin and Shahrud were confirmed in the days that followed, with the Institute for Science and International Security assessing damage to Parchin’s solid propellant production facilities around March 5. So while the campaign moved fast, the full degradation of Iran’s missile production chain unfolded over days, not hours. This article examines what was struck, how effective the campaign was, and what the strategic consequences look like going forward.

How Quickly Was Iran’s Ballistic Missile Production Chain Actually Targeted?
The short answer is that the opening salvo focused on clearing the way, not on the factories themselves. Coalition planners understood that iran‘s layered air defense network — roughly 200 systems spread across the country — had to be neutralized before bombers could safely reach hardened underground missile facilities deeper in Iranian territory. Within the first 24 hours, US and Israeli forces had established effective air superiority from western Iran to central Tehran, which opened corridors for the heavier strikes that followed. Once that window was open, the pace was remarkable. US B-2 stealth bombers, capable of delivering 30,000-pound bunker-busting munitions, struck hardened underground missile facilities, while B-1 bombers hit drone launch sites and military airfields.
Hundreds of IAF fighter jets joined the campaign against production infrastructure. By comparison, Israel’s April 2024 limited strikes on Iran targeted only a handful of sites and lasted a single night. The February-March 2026 operation was an entirely different scale — a sustained, multi-day campaign designed not just to signal displeasure but to physically dismantle Iran’s ability to build and launch ballistic missiles. The distinction matters because the “first 12 hours” framing overstates the timeline for the production chain strikes while understating the scope of what came after. The real story is that within roughly a week, the coalition had systematically hit every major node in Iran’s missile supply chain — from raw material production to engine casting to final assembly.
What Exactly Was Destroyed at Parchin and Shahrud?
Parchin, located southeast of Tehran, has been one of Iran’s most important military-industrial complexes for decades. It drew international scrutiny long before the 2026 strikes for its suspected role in nuclear weapons research. During the Twelve-Day War, Israeli strikes on Parchin targeted factories producing explosive materials for ballistic missile warheads, complexes that manufactured unique raw materials for missile engines, a missile engine mixing and casting facility, and a complex used for the research, development, assembly, and production of advanced cruise missiles. The Institute for Science and International Security assessed that strikes around March 5 destroyed two to three solid propellant production facilities at the site. Shahrud, in north-central Iran, was arguably even more consequential. The IDF described it as the facility “where most of the missiles fired at Israel were manufactured.” Satellite imagery analysis showed extensive damage, with more or less every building in the solid motor production lines damaged and many outright destroyed.
Solid propellant motors are the critical component of Iran’s medium and long-range ballistic missiles — they are what allow a missile to launch on short notice without the hours-long fueling process required by liquid-fueled alternatives. Destroying those production lines did not just eliminate existing inventory; it cut off Iran’s ability to replace what it was losing. However, it is worth noting a limitation of bomb damage assessment from satellite imagery. Underground facilities, which Iran invested heavily in precisely to survive airstrikes, are difficult to evaluate from overhead. While surface-level destruction at both sites was clearly extensive, the full extent of damage to buried production lines and storage bunkers may not be fully known for months or years. Iran has a long history of building redundant, dispersed facilities, and some capacity may have survived in tunnels and hardened shelters that satellite imagery cannot penetrate.
The 86 Percent Drop in Iranian Missile Launches
One of the most striking data points to emerge from the conflict came from General Dan Caine, Chairman of the Joint Chiefs, who reported that Iran’s theater ballistic missile launches were down 86 percent compared to the first day of fighting. The IDF later affirmed that 75 percent of Iranian missile launchers had been destroyed outright. These are not just numbers about hardware — they reflect the simultaneous collapse of three interconnected systems. The decline in Iran’s launch capability was driven by degradation across multiple domains at once: the physical destruction of TEL (Transporter Erector Launcher) vehicles, disruption of command and control networks, and the elimination of production capacity that would have allowed Iran to reconstitute its forces. A TEL is the mobile platform that transports, raises, and fires a ballistic missile.
Destroying a TEL does not just remove one launcher — it removes the trained crew, the communication links, and the logistical chain that supported it. When roughly 300 launchers are destroyed or disabled in a matter of days, the organizational capacity to coordinate what remains also degrades. Iran did attempt retaliatory strikes during the conflict, including targeting an Israeli refinery, but with significantly diminished capacity. The pattern was clear in the data: a sharp initial volley followed by a rapid and sustained decline. this is consistent with a force that expended much of its ready inventory early and then found itself unable to reload, reposition, or replace what it had lost.
Air Defense Suppression — The Prerequisite Nobody Talks About
The strikes on missile production facilities grabbed headlines, but the campaign’s success depended entirely on the less dramatic first phase: the systematic destruction of Iran’s approximately 200 air defense systems. Without suppressing those defenses, neither American bombers nor Israeli fighter jets could have operated over Iranian territory with the frequency and duration needed to hit hardened targets. Establishing air superiority over a country the size of Iran — roughly 1.6 million square kilometers — is a fundamentally different challenge than the air campaigns the US has conducted over smaller adversaries. The coalition achieved effective control of airspace from western Iran to central Tehran within 24 hours, but this required enormous sortie rates and significant expenditure of standoff munitions like cruise missiles and anti-radiation missiles designed to home in on radar emitters.
The tradeoff is that every munition used to suppress air defenses is one that cannot be used against a missile factory or launcher. Coalition planners had to balance the urgency of hitting production sites against the risk of losing aircraft to defenses that had not yet been neutralized. This sequencing also meant that some Iranian assets in the eastern part of the country, farther from coalition bases, may have had more time to disperse or shelter before strikes reached them. Air campaigns move from the periphery inward, and Iran’s geographic depth provided a degree of strategic cushion that smaller countries would not have had.
Can Iran Rebuild Its Missile Production Capacity?
The IDF assessed that the strikes on Parchin and Shahrud set Iran’s missile production capabilities back years, but “years” is a vague and potentially optimistic estimate. Several factors will determine whether Iran can reconstitute its program and how long it will take. Solid propellant production is a specialized industrial process that requires purpose-built facilities, trained personnel, and access to specific chemical precursors. If the workforce — the engineers and technicians who operated these plants — survived the strikes, they retain the knowledge to rebuild given sufficient resources and time. The physical plants can be reconstructed, though doing so under potential future surveillance and the threat of follow-on strikes would push Iran toward even deeper underground construction, which is slower and more expensive.
International sanctions, depending on how they evolve in the post-conflict environment, could also constrain Iran’s access to the raw materials and machine tools needed to restart production. The warning here is that destroying production capacity is not the same as destroying capability permanently. History offers a cautionary parallel: Iraq’s nuclear program was bombed by Israel in 1981 at Osirak, yet Saddam Hussein subsequently pursued nuclear weapons through a more dispersed and covert program. Iran, having now experienced the vulnerability of concentrated production sites, would almost certainly pursue a more distributed model in any rebuild — smaller facilities, deeper underground, spread across more locations. That would make the program harder to target in any future conflict but also slower and less efficient to operate.
The Role of American Bomber Aircraft
The involvement of US B-1 and B-2 bombers was critical to the campaign’s effectiveness against hardened targets. The B-2 Spirit, a stealth bomber capable of penetrating advanced air defenses undetected, can deliver the GBU-57 Massive Ordnance Penetrator — a 30,000-pound bunker-busting bomb designed specifically to reach deeply buried facilities. No Israeli aircraft carries a weapon of comparable size.
This is a practical illustration of why the operation was joint rather than unilateral. Israel’s Air Force is highly capable and carried out the bulk of tactical strikes, but certain categories of targets — specifically the deeply hardened underground facilities Iran built to survive exactly this kind of attack — required American platforms and munitions that simply do not exist in any other country’s arsenal. The B-1 Lancer, while not stealthy, provided additional heavy payload capacity for strikes on less defended targets like drone launch sites and military airfields once air defenses had been sufficiently degraded.
What the Twelve-Day War Means for Future Missile Proliferation
The February-March 2026 strikes against Iran’s missile infrastructure will likely reshape how countries think about ballistic missile programs for years to come. The demonstrated ability of a coalition with air superiority to systematically dismantle an entire production chain — from raw materials to engine casting to final assembly and launch — raises the costs and risks of investing in large, concentrated missile production facilities. For Iran specifically, the path forward is uncertain.
The conflict demonstrated that even a substantial missile arsenal, if its production base can be destroyed, becomes a wasting asset — each missile fired is one that cannot be replaced. The 86 percent decline in launch rates over the course of the conflict illustrated this dynamic in real time. Whether Iran pursues rebuilding under harsher conditions, pivots to alternative deterrence strategies, or seeks a negotiated resolution that trades program limitations for sanctions relief will be one of the defining geopolitical questions of the coming years.
Conclusion
The joint US-Israeli campaign against Iran’s ballistic missile production chain was one of the most intensive and targeted industrial-military operations in modern warfare. Over 3,000 munitions in the first 36 hours, the destruction of Iran’s two most central production sites at Parchin and Shahrud, approximately 300 launchers destroyed or disabled, and an 86 percent decline in missile launch rates — these numbers describe a campaign that achieved its primary military objective of degrading Iran’s ability to produce and fire ballistic missiles. The longer-term picture is less certain.
Production infrastructure can be rebuilt, knowledge persists in the workforce that operated these facilities, and Iran has strong incentives to reconstitute some form of missile deterrent. The IDF’s assessment that the strikes set Iran back “years” may prove accurate, but the precise timeline depends on factors — sanctions enforcement, Iranian resource allocation, the degree of covert capacity that survived — that will only become clear over time. What is clear is that the Twelve-Day War fundamentally altered the balance of missile capability in the Middle East, at least for now.
Frequently Asked Questions
Did the US and Israel strike Iran’s missile production sites in the first 12 hours?
Not exactly. The first phase prioritized destroying roughly 200 Iranian air defense systems. Effective air superiority over the Tehran corridor was established within 24 hours, after which strikes on deeper targets like Parchin and Shahrud became feasible. The major production site strikes occurred in the first week of the conflict.
How many munitions were used in the opening phase?
The US and Israel launched more than 3,000 munitions in the first 36 hours of the operation that began on February 28, 2026.
What is Parchin and why does it matter?
Parchin is a military-industrial complex southeast of Tehran that housed factories producing explosive materials for missile warheads, raw materials for missile engines, an engine mixing and casting facility, and a cruise missile research and production complex. The Institute for Science and International Security assessed that 2-3 solid propellant production facilities there were destroyed.
What happened to Iran’s ability to launch missiles during the conflict?
Iran’s theater ballistic missile launches dropped 86 percent from the first day of fighting, according to the Chairman of the Joint Chiefs. The IDF reported that 75 percent of Iranian missile launchers were destroyed and approximately 300 launchers were destroyed or disabled by March 3.
Can Iran rebuild its missile production capabilities?
The IDF assessed the strikes set Iran’s capabilities back years. Rebuilding requires specialized facilities, trained personnel, and access to chemical precursors that may be constrained by sanctions. Iran would likely pursue a more dispersed and underground model, which would be slower and more expensive.
What American aircraft were involved?
US B-1 Lancer and B-2 Spirit bombers struck hardened underground missile facilities, drone launch sites, and military airfields. The B-2’s ability to deliver the 30,000-pound GBU-57 Massive Ordnance Penetrator was critical for deeply buried targets that Israeli aircraft could not reach.
