Summary

Multiple reports spotlight Iran’s deeply buried Fordow enrichment facility as the centerpiece of escalating tensions with Israel and the United States. Fordow’s location inside a mountain, extensive air defenses, and thousands of centrifuges producing uranium enriched up to 60%—with past spikes near weapons grade—make it both resilient to conventional strikes and central to concerns over rapid breakout potential. Analysts emphasize that only the U.S. GBU-57 Massive Ordnance Penetrator carried by B-2 bombers could plausibly cripple the site, a step Washington has avoided to prevent regional escalation. Israel may still disrupt operations through indirect means like targeting power and access points. Iran, asserting its program is peaceful and IAEA criticism politically motivated, frames any retaliation as lawful self-defense, while canceled U.S.-Iran talks and recent Israeli strikes heighten the risk of miscalculation and proliferation.

Key Points

  • Fordow’s deep underground design makes it highly resistant to conventional airstrikes and central to Israel’s concerns.
  • Only U.S.-deployed GBU-57 bunker-busters on B-2 bombers are seen as capable of seriously damaging Fordow.
  • Iran has enriched uranium up to 60% with past spikes near 83.7%, enabling rapid potential conversion to weapons grade.
  • Israel could hinder, but likely not destroy, Fordow by targeting infrastructure or access points.
  • Iran labels its retaliation and nuclear activities as defensive and peaceful amid rising regional tensions.

Fordow nuclear site: What we know about Iran’s facility hardened against bunker busting bombs | CNNClose icon

CNN examines Iran’s Fordow Fuel Enrichment Plant, a secretive uranium enrichment site buried 80–90 meters inside a mountain near Qom, designed to withstand bunker-busting bombs and difficult to destroy from the air. Built during Iran’s early-2000s “crash” nuclear weapons program, Fordow was revealed in 2009 and has long raised alarms over military dimensions. The JCPOA curtailed its activities, but after the U.S. exited the deal in 2018, Iran expanded operations; the IAEA reports enrichment up to 60% and about 2,700 centrifuges on site. Experts say Iran could rapidly convert existing 60% stock into weapons-grade material, potentially enough for multiple bombs within weeks, making Fordow central to Israeli concerns. Recent Israeli strikes have not visibly damaged the facility; analysts note only the U.S. possesses munitions capable of potentially penetrating Fordow’s depth, underscoring its strategic resilience and the growing nuclear proliferation risk.

Explainer: US bunker-buster bombs and Iran's underground nuclear facilities

The article explains that if the US directly aids Israel against Iran, Washington could supply GBU-57 Massive Ordnance Penetrator “bunker-buster” bombs to target Iran’s deeply buried Fordo uranium enrichment site. The 30,000-pound bomb can penetrate roughly 200 feet and multiple strikes can burrow deeper, but only the US B-2 stealth bomber is configured to deploy it, making US involvement pivotal and politically consequential. Fordo, built into a mountain near Qom and protected by air defenses, is smaller than Natanz but considered critical to Iran’s program; Israel views its destruction as essential. While such strikes risk releasing nuclear material, past incidents at Natanz caused contamination limited to the site, per the IAEA. US willingness to participate remains unclear, and Israeli officials say they have alternative options beyond long-range bombing.

Iran's response to Israeli strikes a 'matter of principle', ambassador to UK says | World News | Sky News

Iran’s ambassador to the UK, Seyed Ali Mousavi, told Sky News that Iran’s retaliation to recent Israeli strikes on its military leaders and nuclear sites is an act of self-defense and a “matter of principle,” accusing Israel of violating international law. He said Iran will defend its territorial integrity and pursue concrete actions against Israel, while insisting Iran’s nuclear program is peaceful and monitored, dismissing IAEA criticism as politically motivated. The comments follow Israeli claims Iran is moving to weaponize enriched uranium and amid canceled US-Iran talks due to escalating tensions.

Iran’s Best-Protected Nuclear Site Is Deep Underground - The New York Times

The article explains that Iran’s Fordo nuclear facility is buried deep inside a mountain and can likely be destroyed only by the U.S.’s 30,000-pound “bunker buster” bomb, deliverable by B-2 stealth bombers. The U.S. has long refused to provide this weapon to Israel to avoid triggering a wider war. Israel, however, could impede Fordo by striking nearby power infrastructure, blocking entrances, or using special operations to disable the site, though fully destroying it remains unlikely. Fordo’s protection reflects lessons from Israel’s 1981 strike on Iraq’s aboveground reactor. While enriched uranium at Fordo has reached 83.7%—near weapons grade—Iran insists its program is peaceful. Any U.S.-enabled strike would carry major risks, including potential radioactive contamination, regional escalation, and political fallout, and President Trump has shown little appetite for deeper military involvement.
