Satellite images from Planet Labs PBC reveal that Iran has constructed roofs over damaged buildings at two nuclear sites—Natanz and Isfahan—that were bombed by Israel and the United States in June 2025. The activity marks the first significant changes observed at these sites since the strikes, which were part of a 12-day conflict between Israel and Iran. The new coverings block satellite surveillance, preventing inspectors from the International Atomic Energy Agency (IAEA) from monitoring the sites, as Iran has denied them access.
Experts suggest the roofs are not indicative of reconstruction but rather an effort to assess and recover any remaining assets, such as highly enriched uranium, without detection. The Natanz site, located about 135 miles south of Tehran, was heavily damaged in the strikes, particularly its above-ground Pilot Fuel Enrichment Plant and underground centrifuge halls. The Isfahan facility, primarily used for uranium gas production, was also targeted. The U.S. and Israel have stated that the strikes significantly degraded Iran’s nuclear capabilities, though Iran maintains its program is peaceful.
The activity at the sites comes amid rising tensions over Iran’s crackdown on nationwide protests and ongoing diplomatic efforts to address its nuclear program. The U.S. has moved military assets into the region, though it remains unclear whether further action will be taken.
