Can US airstrikes actually destroy Natanz's underground enrichment halls?
Latest on Natanz Fuel Enrichment Plant
- What is the Natanz Fuel Enrichment Plant?
- Natanz is Iran's primary uranium enrichment complex in Isfahan Province, housing approximately 5,000 centrifuges in underground halls buried under 8 metres of reinforced concrete and 22 metres of earth. It is Iran's main site for producing enriched uranium.Source: IAEA
- Was Natanz destroyed in 2026?
- No. The US struck Natanz at least twice in 2026, and satellite imagery confirmed surface structural damage to entrance buildings. However, the IAEA stated it could not confirm the underground enrichment halls were destroyed. Iran holds roughly 440 kg of 60%-enriched uranium, enough for approximately 10 weapons, and airstrikes have not altered that stockpile.Source: IAEA
- Can the GBU-57 destroy Natanz?
- The GBU-57 Massive Ordnance Penetrator was not confirmed used against Natanz in 2026. The munitions deployed — GBU-31 2,000-lb bombs with BLU-109 warheads — penetrate approximately 1-2 metres of reinforced concrete, which is insufficient for Natanz's underground halls protected by 8 metres of concrete and 22 metres of earth.Source: The War Zone / Army Recognition
- Why did the US strike Natanz and not Israel?
- The IDF denied involvement in the second US strike on Natanz in 2026, indicating a unilateral US operation. The US separately used its heavier ground-penetrating GBU-72 munitions at other Iranian sites; Natanz requires the most capable bunker-busters in the US arsenal.Source: IDF / IAEA
- How does Natanz compare to Fordow?
- Both are underground Iranian enrichment facilities struck by the US in 2025-26. Fordow is built inside a mountain, making it even harder to destroy than Natanz. The GBU-72 Advanced 5K Penetrator was confirmed used against Fordow; the same weapon was not confirmed used at Natanz in the same strikes.Source: CENTCOM
Background
Located near Natanz in Isfahan Province, the plant comprises surface infrastructure and underground halls buried under 8 metres of reinforced concrete and 22 metres of earth, designed to defeat conventional bunker-busters. Iran holds roughly 440 kg of 60%-enriched uranium across its enrichment sites, enough for approximately 10 weapons if further enriched.
Natanz Fuel Enrichment Plant became a primary military target when the Iran-Israel-US Conflict 2026 drew in direct US strikes. Washington hit the facility twice; Iran confirmed the second strike, the IAEA reported no radiation leak, but could not confirm from satellite imagery whether the underground halls housing approximately 5,000 centrifuges were destroyed. The second strike prompted Iranian retaliatory missiles on southern Israel the same day.
The facility crystallises the central strategic question: can airstrikes eliminate Iran's nuclear programme? Rafael Grossi stated that the material and enrichment capacity will likely outlast any military campaign. Defence analysts confirmed that the munitions deployed were insufficient to penetrate Natanz's underground halls.
