Vantor Technologies satellite imagery from September 13, 2026, shows that Iran is rapidly moving forward with the reconstruction of the Taleghan 2 facility located at the Parchin military complex. Iran has erected a tarp above the destroyed hardened buried facility, hiding the reconstruction activity that is occurring underneath from satellite view or aerial reconnaissance (see Figure 1). Significant activity can be seen throughout the construction site. Construction vehicles, including dump trucks, bulldozers, concrete pump trucks and concrete mixers, and cranes, are actively working to rebuild the facility (see Figure 2). Repair and rehabilitation work began in June 2026, first with Iran repairing and placing concrete caps over the penetration holes caused by the multiple bunker buster weapons dropped on the facility.[1] Iran has also built a new concrete apron reinforcement on the right side of the facility, the one on the left side that we noted in our July 2026 update now appears complete. This will provide additional blast protection from an aerial attack.
The facility has been attacked twice: first in October 2024, then after having been rebuilt from May 2025 as a hardened buried facility, it was attacked again in early March 2026.[2] The second attack saw the use of multiple bunker buster weapons against the facility, blowing out the internal structure and causing surrounding structures to collapse. During its reconstruction starting in May 2025, the Institute observed the installation of a cylindrical structure, which may have been a high explosive containment vessel. Given the precision of the March 2026 attacks, the high explosive containment vessel was likely destroyed.
Significant questions remain as to Iran’s plans for the facility; not least is why Iran keeps rebuilding it. What is clear is that Iran remains committed to rebuilding this facility, a deeply concerning development considering the long history of nuclear weapons research and development activities that occurred there.
