Iran rebuilds Taleghan 2 facility at Parchin military complex

Iran is reportedly rapidly rebuilding the Taleghan 2 facility at the Parchin military complex, located southeast of Tehran. The site, a former nuclear weapons program location, has been covered with a large tarp to conceal heavy construction work, which includes dump trucks, bulldozers, concrete pumps, cranes, and new blast-reinforcement walls.

This marks the third rebuild cycle for the facility. Israel previously struck the building in October 2024, after which Iran rebuilt it with a new high-explosive containment vessel. Israel struck the site again in March 2026 using bunker-busters, destroying the internal structure. Repairs began by June 2026 and are now accelerating under concealment. The Institute for Science and International Security has described the repeated rebuilding as deeply concerning.
