A military structure located near Tabriz, Iran, constructed to house Iran's ballistic missile forces. The bunker's existence was confirmed by the release of footage showing its capabilities, which was used to demonstrate Iran's military strength in response to Western concerns about military options against the country. The bunker's construction is believed to have been a response to the 2015 nuclear deal and the subsequent threat of military action by the US.
The site's defensive capabilities are highlighted by the use of bunker-busting bombs, such as the B-2 Spirit, which were deployed in a 2026 strike against Iranian nuclear sites.
