Iran tests rocket-launched sea mines to speed attacks in the Hormuz Strait

U.S. strikes on Larak Island targeted Iranian rocket launchers after reports that the weapons were being prepared to launch sea mines into the Strait of Hormuz, marking a return to attacks after a month’s pause. Traditionally, Iran has scattered mines using fast boats, submarines or low-altitude aircraft, but land-based launchers would allow rapid deployment from shore. The idea was first publicised by Iranian state television in January 2025, which described the Fajr-5 multiple-launch rocket system as capable of laying mines in the strait.

Security specialists say the shift could let Tehran place explosives more quickly and with less risk to personnel, though some experts question whether the mines would survive the launch impact. Analysts suggest parachute-equipped munitions might mitigate damage on water entry. The development adds a new dimension to the already tense maritime security situation in the region.
