A secret nuclear facility in Fordow, located in the mountains south of Tehran, has become a focal point in the ongoing tensions between Israel and Iran, with the U.S. stepping in to assist Israel in countering Tehran’s nuclear ambitions.
The Fordow site, officially referred to as the Fordow Fuel Concentration Plant internationally and known in Iran as the Shahidha Arimohamadi facility, is buried under over 300 feet of rock. Attacking it would require significant firepower.
While the United States possesses large bombs called “bunkerbusters” capable of penetrating such sites, Israel lacks that capacity.
Iran’s Capabilities at Fordow
The International Atomic Energy Agency (IAEA) last confirmed the enrichment levels at Fordow on May 28th. Recent analyses stemming from IAEA reports indicate that Iran has accumulated enough centrifuges, including more advanced IR-6 models, and uranium hexafluoride gas to potentially produce multiple nuclear weapons.
It was mentioned in a bulletin that Iran could likely generate sufficient weapons-grade uranium (around 90% enriched) for one nuclear weapon in just five to six days.
The underground nature of Fordow suggests it could potentially continue functioning even if other nuclear facilities in Iran were compromised, allowing it to covertly develop nuclear arms.
One analyst noted that the Fordow facility is crucial for Iran’s goal of maintaining its nuclear capabilities. If Israel pursues military options against Iran’s program, they would have to neutralize the Fordow Plant to mitigate the threat it poses.
A Brief History of Fordow
In September 2009, President Obama publicly disclosed the existence of the Fordow facility. He described it as being constructed in blatant disregard of various Security Council and IAEA resolutions, asserting that its dimensions and operations are inconsistent with peaceful nuclear objectives.
While Iran had previously revealed its Natanz enrichment sites, the Fordow facility’s existence was initially kept secret.
Obama indicated that Iran’s decision to build yet another nuclear site without informing the IAEA was a direct affront to the treaty framework aimed at preventing nuclear proliferation.
During the Obama administration, the IAEA was granted daily access for monitoring purposes under the Joint Comprehensive Plan of Action (JCPOA). However, following the U.S. withdrawal from the deal in 2018, Tehran progressively limited international oversight, ultimately removing all monitoring equipment from Fordow in 2022.
What Lies Ahead?
Under Trump’s second administration, efforts to secure a new nuclear agreement with Iran aimed at curbing weapons development have faced setbacks, particularly following Israel’s recent military actions against Iranian interests.
Experts are left pondering the implications if Fordow remains intact. One analyst suggested the possibility of negotiating terms that would allow IAEA access to the site, similar to arrangements prior to June 13th.
Even if a deal were reached permitting continued uranium enrichment at Fordow, concerns about the potential for rapid nuclear weapons production may now be greater than they were before.
