Satellite Images Show Activity at Two Iranian Strategic Nuclear Sites
New satellite imagery comparing late June and early July 2026 has revealed renewed activity at two of Iran’s most closely watched strategic nuclear-related sites, indicating ongoing engineering and reconstruction work.
The first location is the Parchin Military Complex, specifically the Taleghan 2 building. The underground facility has long been identified by analysts as a site linked to high-explosives testing and research associated with nuclear weapons development.
According to the satellite images dated June 22 and July 7, workers appeared to be covering three large impact craters on the bunker roof with camouflage netting and screening materials. Heavy construction equipment, including concrete mixers and large cranes, was also observed installing reinforced steel mesh before pouring concrete, suggesting efforts to repair and reinforce the damaged underground structure.
The second location is the Pickaxe Mountain underground facility near Natanz. The site, built beneath an estimated 80–100 meters of granite rock, is believed to house uranium centrifuge infrastructure designed to withstand air strikes. Satellite imagery dated June 21 showed increased activity around the tunnel entrances, with military trucks and engineering vehicles reportedly moving in and out of the complex, indicating continued work inside the underground facility.
The satellite observations have not been independently verified, and Iranian authorities have not publicly commented on the reported construction activity.
