A resurfaced video from 2025 showing Iran’s underground naval tunnel network in the Persian Gulf has drawn renewed attention as tensions escalate between Iran, the United States, and Israel. The footage, originally released by Iran’s Islamic Revolutionary Guard Corps (IRGC), reveals a vast concealed facility carved into coastal terrain, reportedly housing dozens of fast-attack missile boats designed to launch sudden strikes against naval targets operating in the region.

Military analysts note that the strategic purpose of such facilities is clear: survivability and surprise. By embedding naval infrastructure deep inside mountain formations or coastal rock structures, Iran reduces the vulnerability of its forces to preemptive airstrikes. When combined with high-speed missile boats equipped with anti-ship weapons, the tunnels create a launch platform designed to threaten shipping lanes and naval patrols in the Persian Gulf, one of the world’s most critical maritime chokepoints for global energy supply.
