The destruction of Iran's nuclear program was the stated primary objective of Operation Epic Fury—the coordinated US-Israel military campaign launched on February 28, 2026. Within the first 72 hours, American B-2 stealth bombers and Israeli F-35I Adir jets delivered precision strikes against facilities that had taken Iran decades and billions of dollars to construct. Three weeks into the conflict, intelligence assessments suggest that Iran's path to a nuclear weapon has been set back by at least 15 to 20 years—if not permanently destroyed.
But what exactly was hit? The fog of war, competing propaganda narratives, and classification of operational details have made it difficult to assemble a clear picture. This analysis compiles confirmed strikes from Pentagon briefings, IDF announcements, IAEA preliminary reports, and satellite imagery analysis to document exactly which nuclear facilities were targeted and what the strikes mean for global nonproliferation.
The Primary Targets: Iran's Enrichment Infrastructure
Iran's uranium enrichment program—the core of its nuclear capabilities—was centered at two primary facilities. Both were struck in the opening hours of the campaign:
Iran's largest enrichment complex, located 250 kilometers south of Tehran, was the first target struck by US B-2 bombers using GBU-57 Massive Ordnance Penetrators (MOPs)—30,000-pound bunker-buster bombs designed specifically for deeply buried targets. Natanz housed thousands of IR-6 and IR-8 advanced centrifuges in underground halls buried under 20 meters of reinforced concrete. Multiple MOP strikes collapsed the underground facility, destroying centrifuge cascades that had been enriching uranium to 60% purity—just below weapons-grade 90%.
Buried inside a mountain near Qom, Fordow was considered Iran's most hardened nuclear facility. IDF officials claimed multiple penetrating strikes using Israeli-modified bunker busters. While the depth of the facility (reportedly 80 meters underground) makes complete destruction uncertain, Pentagon sources indicate that access tunnels and ventilation systems were collapsed, rendering the facility inoperable. IAEA inspectors—evacuated before the strikes—have been unable to return to verify conditions.
Research and Development: The Brain of the Program
Beyond enrichment facilities, US-Israeli strikes targeted the research infrastructure that provided the intellectual foundation for Iran's nuclear ambitions. The Isfahan Nuclear Technology Center—home to uranium conversion facilities that transform yellowcake into uranium hexafluoride gas for centrifuge feeding—sustained major damage in Day 2 strikes. Satellite imagery revealed multiple large craters and destroyed buildings within the complex.
The IDF also announced the destruction of a previously covert facility identified as "Min Zadai"—described as a secret nuclear research site that Western intelligence had been monitoring. Details remain classified, but Israeli officials claimed the site contained evidence of weapons design work that violated Iran's NPT obligations. This revelation, if confirmed, would represent the most significant discovery since the Mossad's 2018 seizure of Iran's nuclear archive from a Tehran warehouse.

Heavy Water and Plutonium Pathway
Iran's potential plutonium pathway to a nuclear weapon—centered on the Arak Heavy Water Reactor—was also targeted. The reactor, which had been redesigned under the 2015 JCPOA agreement to limit plutonium production, was struck by Israeli precision munitions on Day 1. The destruction of Arak closes Iran's secondary route to fissile material, complementing the elimination of the enrichment pathway through Natanz and Fordow.
Additional strikes targeted the Bushehr Nuclear Power Plant, Iran's only operational civilian reactor. While the Bushehr facility operates under IAEA safeguards and produces electricity rather than weapons-grade material, its destruction—confirmed by Russian objections at the UN Security Council—appears designed to eliminate any residual nuclear infrastructure that could be repurposed.
The Missile Connection: Shahid Hemmat Industrial Group
Nuclear weapons require delivery systems, and Operation Epic Fury systematically targeted Iran's ballistic missile production capabilities alongside nuclear facilities. The Shahid Hemmat Industrial Group—responsible for developing Iran's liquid-fueled Shahab and Emad ballistic missiles—was struck repeatedly. IDF reports indicate that missile production lines, engine test stands, and guidance system workshops were destroyed across multiple sites.
The targeting of missile facilities alongside nuclear sites reflects the "dual-key" strategy: even if Iran somehow reconstituted its enrichment capabilities, the destruction of delivery systems would prevent weaponization. Intelligence analysts estimate Iran's missile production capacity has been reduced by over 70%, though mobile launcher units deployed before the strikes remain operational and continue firing at Gulf State targets.
Intelligence analysts caution that "destroyed" in military terms does not necessarily mean "permanently eliminated." Iran's nuclear knowledge—the scientific expertise of its physicists and engineers—cannot be bombed away. Equipment can be rebuilt, facilities reconstructed, and programs restarted given sufficient time, resources, and political will. The 15-20 year setback estimate assumes Iran would need to rebuild centrifuge manufacturing capabilities, train new technical personnel, and construct new facilities—all while under international scrutiny and likely continued sanctions. The question is not whether Iran could restart its program, but whether the post-war political environment would allow it to do so.
IAEA Response and Verification Challenges
The International Atomic Energy Agency evacuated its monitoring personnel from Iran before the strikes began, leaving the international community without independent verification of either the damage inflicted or the pre-war status of Iran's program. IAEA Director General Rafael Grossi called the strikes "a devastating blow to the international safeguards regime" and warned that the destruction of monitoring equipment means the agency may never be able to confirm whether Iran had achieved weapons-grade enrichment before the attacks.
This verification gap creates a dangerous precedent. Without IAEA confirmation of what Iran possessed before the strikes, intelligence agencies cannot definitively assess whether all weapons-relevant material was destroyed—or whether some was dispersed to unknown locations before the bombing began. Iran's history of covert parallel programs makes this uncertainty particularly concerning.
Conclusion: A New Nuclear Landscape
The destruction of Iran's nuclear program represents the most significant act of nuclear counter-proliferation since Israel's 1981 strike on Iraq's Osirak reactor. Unlike Osirak—a single surgical strike against one facility—Operation Epic Fury systematically dismantled an entire nuclear ecosystem: enrichment plants, research centers, heavy water reactors, missile production facilities, and command infrastructure.
Yet the strategic implications remain contested. Critics argue that military strikes cannot permanently eliminate nuclear knowledge, and that the destruction of Iran's program—achieved outside international law and without UN authorization—undermines the nonproliferation regime itself. Supporters counter that decades of diplomacy failed to prevent Iran from reaching the threshold of weapons capability, and that military action was the only remaining option.
As the war cost counter continues its relentless climb, one thing is clear: the billions spent on destroying Iran's nuclear infrastructure represent only a fraction of the total price the world will pay for this conflict. Whether that price proves worth paying depends on whether the diplomatic order that follows can prevent the next aspirant from walking the same path.
