Iran’s underground missile and ammunition facilities withstood the 12-day conflict and US strikes thanks to two decades of hardening and design, said Iran’s passive defense chief in an interview with the Story of the War podcast on Saturday.
“Almost all underground and under-mountain missile infrastructure remains intact and has no serious problems,” Gholamreza Jalali said, crediting long-running operational measures and engineering choices.
The priority given to aerospace and missile assets, Jalali said, guided 20 years of planning for missile cities and depots built into mountains and deep underground. Only minor repairable damage occurred at some access points, he added.
Underground networks and nuclear sites
Sensitive nuclear centers, Jalali said, were placed in safe spaces after early threat assessments, adding that he personally proposed the protected design concept years ago.
“The shadow of war was present from the very beginning of our activities, and based on the threat scenarios, it was decided that sensitive nuclear sites should be designed in secure underground locations beneath mountains.”
During the 12-day war and the US attacks on nuclear facilities, added Jalali, some foreign reports highlighted the confrontation between “bunker buster bombs” and Iranian concrete engineering. “It was an oversimplified interpretation of designs."
“Regarding the US claim of destroying nuclear facilities, it must be said that further details remain classified and confidential,” he added.
Banks cyber security not addressed yet
Jalali pointed to cyber-attacks on Iranian banks, saying two major banks shared a core platform with unresolved weaknesses. “For banking security, we designed a regional secure model and obtained funding, but execution rests with the relevant bodies,” he said.
During the June conflict, Iran’s Bank Sepah and Bank Pasargad were hit by major cyberattacks that disrupted online banking and ATM services.
Jalali also addressed the use of foreign messaging platforms by military figures, saying none of Iran’s commanders, living or dead, had ever used WhatsApp, while reports suggested some Hamas leaders had relied on it.
Advanced surveillance and data-analysis systems – spanning artificial intelligence, satellites, and signal tracking – are fully controlled by Israel and the United States, he said, adding that using such platforms exposes communications to monitoring and targeting.
“When we are in confrontation with such adversaries, we must assume total visibility across digital space.”
Former communications minister Mohammad Javad Azari Jahromi said in August that Iranian officials with sensitive information on their phones were easy targets for Israeli cyber operations during June's 12-day war, adding that Israel exploited platforms such as WhatsApp to track them.
“In the recent war, those who had information and were of interest to Israel were easy prey for hacking,” Azari Jahromi said, but did not identify those targeted.
Shelters kept confidential
Tehran has multiple shelter options, including metro stations, car parks, and basements, but officials avoided announcing them publicly to prevent panic, he added.
Local authorities received training to guide people in emergencies, while Tehran Municipality was working to upgrade facilities and warning systems for possible use as public shelters, according to him.
Iran had fully expected attacks on its nuclear facilities and launched a plan to prepare, he added.
Limited drills in Kashan and broader exercises at Fordow, Natanz, and Isfahan helped minimize risks, Jalali said, adding that chemical storage was cleared and activities scaled back before strikes, and post-attack tests confirmed no radioactive contamination.
