Iran has recently resumed production of ballistic missiles at underground facilities using components accumulated in existing stockpiles, according to U.S. and Middle Eastern officials cited in a report by The Wall Street Journal.
According to the report, intelligence has detected activity at several underground sites across Iran, including the Khojir missile facility southeast of Tehran, a major center associated with Iran’s ballistic missile program. The renewed activity indicates Tehran is working to restore missile-production capabilities while increasingly moving sensitive operations beneath the surface.

Officials said Iran is simultaneously establishing new underground assembly sites in an effort to reduce the vulnerability of its production lines and protect them from future strikes. Moving more of the assembly process underground could make the facilities more difficult to detect, target and damage in future military operations.
The developments come amid continued scrutiny of Iran’s efforts to rebuild strategic military capabilities damaged during the conflict, with its ballistic missile arsenal remaining a central concern for Israel and the United States. The White House neither confirmed nor denied the details contained in the report. Israel’s Prime Minister’s Office also declined to comment when approached about the intelligence.
