On June 21, 2025, the United States carried out Operation Midnight Hammer, deploying B-2 stealth bombers armed with GBU-57 massive bunker busters and cruise missiles to strike Fordow, Natanz and Isfahan — the three key facilities in Iran’s nuclear program, which has reportedly benefited from North Korean technical support — in what marked the first large-scale direct U.S. military action against those sites. The number of bunker busters dropped on Fordow, an underground facility buried beneath a mountain range, drew immediate attention from military analysts worldwide.
Using satellite imagery, this analysis reviews the damage inflicted on each of the three Iranian nuclear facilities and examines whether a comparable military operation could be applied to North Korea’s nuclear infrastructure.
The conclusion: while North Korea’s nuclear facilities are technically vulnerable to military strikes, they are dispersed across multiple underground sites, and North Korea has already acquired the deterrent of nuclear retaliation. A preemptive strike of the kind carried out against Iran would therefore not be an ordinary military option, but a strategic option of last resort.
Fordow Uranium Enrichment Plant
The Fordow Uranium Enrichment Plant, an underground facility in Iran’s Qom province, sustained heavy damage in the U.S. air strikes. Satellite images taken the following day and released by Maxar Technologies show four collapsed tunnel entrances and four craters surrounded by debris, presumed to be the bunker buster impact points — a pattern consistent with surface collapse following ordnance penetration through mountain bedrock.
Unclassified documents indicate that U.S. bunker busters are capable of penetrating dozens of meters underground. But because the Fordow facility is believed to sit roughly 80 to 90 meters (260 to 295 feet) below ground, questions remain about whether a single strike could have completely destroyed the underground uranium production base.
Isfahan Nuclear Technology Center
The Isfahan Nuclear Technology Center is a large-scale complex that served as a central node in Iran’s nuclear fuel cycle, housing a uranium conversion facility, a nuclear fuel production facility, an experimental nuclear reactor, a fissile material storage facility and a range of laboratories. It handled upstream production of the precursors to nuclear fuel bound for enrichment facilities such as Natanz and Fordow.
The U.S. bombed the center in June 2025 using Tomahawk cruise missiles and precision munitions. Satellite images from October show the ruins of targeted buildings, their charred frames still standing. Because some fissile material and key equipment may have been dispersed or relocated in advance, analysts regard the strike as having temporarily delayed Iran’s nuclear program without fundamentally eliminating its capabilities.
Natanz Uranium Enrichment Plant
Located in the desert of central Iran, Natanz is Iran’s largest enrichment facility, with tens of thousands of centrifuges capable of converting low-enriched uranium into highly enriched uranium. The U.S., working in coordination with Israel, bombed the complex in June 2025, destroying the aboveground enrichment plant, power generators, transformers and a range of support buildings.
The International Atomic Energy Agency, analyzing satellite imagery and other intelligence, identified signs of damage to the underground enrichment hall and concluded that its centrifuges were probably compromised by the destruction of the power supply infrastructure. As with Isfahan, speculation persists that some material and equipment was hidden before the attack, and the prevailing assessment is that Iran’s nuclear program was not completely destroyed.
Are North Korea’s nuclear facilities vulnerable to the military option?
The key components of North Korea’s nuclear program are the Yongbyon nuclear complex in North Pyongan province, the nuclear test site at Punggye-ri in North Hamgyong province, and a series of locations in Kangson, Pakchon and Pyongsong believed to be classified uranium enrichment sites.
Yongbyon is a research and production complex of hundreds of buildings, including a plutonium production reactor, a radiochemical laboratory and a uranium enrichment facility. It is widely regarded as the technical nexus of North Korea’s nuclear weapons program.
Unlike Iran’s Fordow facility, however, North Korea’s nuclear infrastructure is not concentrated in a single mountain bunker. It is dispersed across aboveground industrial facilities and underground galleries, which complicates any military strike calculus: while individual facilities could be physically destroyed, eliminating North Korea’s overall nuclear capability would be far less feasible.
From a purely military standpoint, the GBU-57 Massive Ordnance Penetrator and high-velocity penetrators in the U.S. and allied arsenals are thought capable of physically destroying many of North Korea’s underground facilities. The Yongbyon complex’s reactor, reprocessing facility, power infrastructure and cooling system are all exposed and could be functionally paralyzed by precision air strikes or cruise missile attacks.
North Korea’s main enrichment facilities and fissile material depots, however, are believed to be hidden in underground locations that would be difficult to identify or confirm as targets. While repeated nuclear tests at Punggye-ri are thought by some analysts to have weakened the surrounding ground, there is also speculation that new tunnels are being constructed there. Blocking entrances or triggering a landslide are therefore regarded as more practical scenarios than a direct strike on the test site.
Strategically, a strike on North Korea’s nuclear facilities carries a far greater risk of escalation than the Iran operation. North Korea’s nuclear sites are scattered and concealed in underground tunnel networks and mountain bedrock, making complete elimination in a single strike virtually impossible. And because North Korea would likely carry out massive retaliation, including the potential use of nuclear weapons, any such strike risks triggering all-out war or nuclear catastrophe.
Experts believe North Korea may have accumulated enough fissile material to produce several dozen to as many as 100 nuclear warheads. The military option is therefore discussed primarily in terms of deterrence signaling or crisis management. For most military analysts, the most viable policy remains a combination of diplomacy, sanctions and deterrence.
