Iran has accumulated about 22,000 pounds, or 11 tons, of enriched uranium since the United States withdrew from the nuclear deal eight years ago. Despite a U.S. military campaign launched two months ago to prevent Iran from developing nuclear weapons, the current status of this stockpile remains unclear. The uncertainty follows U.S. airstrikes in June 2025 on Iran’s enrichment facilities at Natanz and Fordow, and on uranium storage tunnels in Isfahan.

After the attacks, Iran suspended cooperation with the International Atomic Energy Agency, ending direct monitoring of its enrichment sites. Satellite imagery has not resolved where the uranium is stored, and some of it may be buried under war debris. Experts say that even if Iran retrieves the material, it would take many months to convert it into weapons-grade fuel. The Trump administration claims U.S. satellites are tracking the buried uranium, but analysts question this, suggesting Iran may have moved much of its stockpile to a new underground site near Isfahan.

The situation leaves open the possibility that Iran retains a hidden enrichment facility capable of restarting weapons-related activities if conditions allow.
