The images show long tunnels lined with naval drones, anti-ship missiles and sea mines. Additional footage depict some of the weapons being launched. It remains unclear when the recordings were made and whether the site has since been struck by American or Israeli forces.
One still image from the material shows a tunnel containing a naval drone mounted on a trailer beneath a portrait of Supreme Leader Ayatollah Ali Khamenei.
naval drones, also known as unmanned surface vehicles or USVs, have already struck two oil tankers in the Persian Gulf. The vessels were attempting to pass through the narrow chokepoint at Hormuz. These small craft travel either on or just below the water's surface. They carry explosives and are intended to detonate on impact.
On March 1, a crude oil tanker named MKD VYOM, registered in the Marshall Islands, was hit 44 nautical miles off the coast of Oman. Britain's United Kingdom Maritime Trade Operations agency reported that an unmanned surface vessel struck the ship just above the waterline, causing an explosion and fire in the engine room. One crew member died.
