Activity Remains Dormant at Pickaxe Mountain
Vantor Technologies imagery from October 7, 2026, shows that the Eastern tunnel entrances remain blocked by earth. The earthen mound roadblocks leading to the Western tunnel portals also remain in place.
Significant Activity Identified at Minzadayi, an Iranian Nuclear Weapons Development Site
High resolution VANTOR Technologies satellite imagery from September and October 2026 shows significant renewed activity at Minzadayi, a nuclear weapons development compound northeast of Tehran revealed by Israel during the 2026 war. The compound was attacked by Israel on March 3rd, 2026, destroying several buildings and likely underground structures.
Iran is Rapidly Reconstructing Taleghan 2
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. 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. 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.
Imagery Update: Passive Defenses Identified at Natanz and Pickaxe Mountain
Vantor Technologies imagery from September 11, 2026, shows that the earthen mound roadblocks are still in place, blocking ground vehicle access to the Western tunnel portals. The week-long restricted access reinforces the assessment that the facility is not currently used for operations, but that it does contain valuable equipment and/or materials. The clearly visible roadblocks mean a return to regular access and activity at the Western tunnel entrances should easily be detected by U.S. intelligence and visible on commercially available imagery. Together with the previously blocked Eastern tunnel entrances, the new roadblocks effectively established a status quo inside the facility starting in early August.

Iran’s nuclear weaponization sites: reconstruction and cleanup activity (June–October 2026)
Over the last few months, we have seen high levels of activity at certain nuclear weaponization sites pointing to reconstruction efforts specifically at Taleghan 2 (starting in June 2026), notable vehicle activity at Minzadayi (September/October 2026) and significant cleanup including the removal of containers at Mojdeh / Malek Ashtar University (August/September 2026). Hardly any activity has been observed at known sites tied to uranium enrichment where the main entrances remain destroyed / blocked by earthen materials and on which the media and public at large tend to focus: Pickaxe Mountain (as of October 7), the Natanz Nuclear Complex (as of October 7), Fordow (as of October 11), and Esfahan (October 12).
