US Navy SEALs conducted covert four-month mission to clear Strait of Hormuz mines

The Jerusalem Post

US Navy SEALs conducted a covert four-month mine-clearing operation in the Strait of Hormuz to secure critical shipping lanes after US and Israeli strikes on Iran in February 2026. Operating primarily at night, elite divers utilized unmanned surface vessels and specialized sonar to locate and neutralize approximately 80 Iranian-laid mines.

This clandestine effort responded directly to Tehran's deployment of underwater explosives in international and Omani waters, which had paralyzed commercial maritime traffic and spiked global shipping insurance rates. The tactical success of the mission allowed US President Donald Trump to declare the international waters mine-free. Complete clearance remains unverified. Iran retains the capability to rapidly re-mine the shallow waterway using small-boat traffic. This persistent threat preserves Tehran's strategic leverage over the vital chokepoint. Oil prices briefly dipped five percent following the White House announcement but quickly rebounded as regional strikes resumed.

Comment

The covert deployment of US Navy SEALs in the Strait of Hormuz exposes the severe limitations of conventional mine-countermeasure platforms in contested littoral zones. By relying on low-profile combat swimmers and unmanned surface vessels rather than traditional Avenger-class minesweepers, the US Navy's Fifth Fleet adapted to the threat of Iranian shore-based anti-ship missiles. This tactical shift demonstrates that clearing modern underwater explosives in narrow chokepoints like the Strait of Hormuz requires stealth assets to avoid triggering wider escalatory strikes.

Consequently, the persistent threat of rapid re-mining by Iranian Islamic Revolutionary Guard Corps Navy fast-attack craft ensures that the Strait of Hormuz remains a high-risk zone despite temporary clearance. This enduring vulnerability will likely force commercial shipping syndicates to maintain elevated war-risk insurance premiums for transit through Omani waters. Ultimately, the reliance on clandestine special operations forces for routine sea-lane clearance diverts elite Navy SEAL teams from high-intensity deterrence missions in the Indo-Pacific theatre.

Strategic Question for Discussion

If the US Navy must repeatedly divert Navy SEAL teams from the Indo-Pacific theatre to perform mine-clearing operations in the Strait of Hormuz, how does this resource strain affect the operational readiness of US special operations forces in potential high-intensity conflicts elsewhere?

The persistent diversion of Navy SEAL teams to secure the Strait of Hormuz indicates a critical gap in the US Navy's surface mine-countermeasure fleet, which is currently transitioning away from aging Avenger-class ships. My assessment is that this operational friction will degrade special operations readiness for specialised littoral reconnaissance missions in the South China Sea. The pattern suggests that until unmanned underwater vehicles are fully integrated into standard fleet operations, high-demand special warfare units will remain tethered to low-tech defensive tasks.
