Satellite imagery shows that Iran has recently constructed a large concrete shield over a new facility at a sensitive military complex, amid continuing acute tensions with the United States and Israel, experts say.
The images, analyzed by independent specialists and released this week, reveal that the newly built structure at the Parchin military complex, southeast of Tehran, is now covered with concrete and soil, obscuring the site from above. Analysts say the measure likely aims to protect key installations from potential airstrikes or other attacks.
Parchin has long been a focus of Western intelligence, which has linked parts of the complex to tests relevant to nuclear weapons development, allegations Tehran denies. The concrete covering appears to have been applied between late 2025 and early 2026, with the facility now virtually invisible in recent imagery.
The imagery also shows additional activity across Iran’s strategic sites. At the Isfahan nuclear complex, tunnel entrances damaged in previous strikes have been completely buried under soil. Near the Natanz nuclear site, defensive fortifications have been erected around underground tunnel access points. Iran has also begun repair work on missile bases at Shiraz and Qom that were damaged in last year’s conflicts.
These developments come as Washington continues diplomatic efforts with Tehran on the nuclear file, even as US officials maintain that military action remains a possible option if negotiations falter. The satellite revelations underscore Tehran’s efforts to harden and conceal its military and nuclear infrastructure against potential threats from the United States and Israel.
