Tensions between Iran and the United States are rising as the confrontation around the strategic Strait of Hormuz intensifies. Iran has resurfaced dramatic footage—first released in 2025—showing underground naval tunnel networks packed with fast-attack boats, anti-ship missiles, and naval mines. The facilities, reportedly operated by the Islamic Revolutionary Guard Corps, are believed to house hundreds of cruise missiles stored deep underground. Analysts say the tunnels form part of Iran’s asymmetric naval strategy designed to challenge powerful fleets operating in the vital Gulf waterway.
