U.S. Mine-Clearing Operations in the Strait of Hormuz

U.S. Mine-Clearing Operation
Following Iranian claims of laying mines in the Strait of Hormuz, the U.S. Navy has deployed two Avenger-class minesweepers and unmanned systems to clear the waterway, despite having retired most dedicated minesweepers.
Background & Context
The strait carries roughly 20 % of global oil. Hostilities between the U.S.–Israel coalition and Iran escalated in February 2026, prompting Iranian minelaying and a U.S. naval blockade of Iranian ports.
Key Players
President Donald Trump, Defense Secretary Pete Hegseth, retired Vice Adm. Kevin Donegan, analyst Bryan Clark (Hudson Institute), Admiral Brad Cooper, Iran’s Islamic Revolutionary Guard Corps (IRGC), Speaker Mohammad Bagher Ghalibaf, and experts Emma Salisbury and Paul Heslop.
Operational Assets & Technology
USS Chief and USS Pioneer (Avenger-class) moved from Southeast Asia; littoral combat ships USS Tulsa and USS Canberra operate nearby. Unmanned underwater drones (Kingfish, Barracuda) and surface sonar drones map the seabed; helicopters and EOD teams handle neutralization.
Data & Timeline
Intelligence cites at least a dozen mines, with some estimates in the low-thousands. The Pentagon told Congress clearance may take up to six months; war-gaming suggests detection within weeks.
Impact
The strait’s closure threatens oil markets and raises insurance premiums. Shipping firms now need Iranian clearance certificates, reflecting lingering safety concerns even after mines are removed.
Official Statements & Responses
Trump ordered the Navy to engage any vessel laying mines and to increase minesweeping activity. Hegseth affirmed rules of engagement and warned that further minelaying would breach the cease-fire. Cooper confirmed ongoing clearance; Iran’s IRGC warned of a “bee fleet.”
Criticism & Opposition
Analysts like Clark say the Navy is at a low point in its mine-sweeping capacity, with limited unmanned assets. Salisbury notes that perceived safety may lag behind physical clearance. Heslop stresses mines’ mobility.
Conflicting Reports & Gaps
Estimates of mines range from fewer than 100 to low-thousands. The Pentagon’s six-month timeline differs from war-gaming’s weeks-long detection. No public evidence confirms any mine’s location or neutralization.
Verbatim Quotes
- “To be honest, that the minesweepers retired was never a concern to me, because we had brought in newer technology,” — Vice Adm. Kevin Donegan, retired
- “We’re sort of at this nadir of the Navy’s mine sweeping capacity,” — Bryan Clark, Hudson Institute
- “Our commanders have clear rules of engagement. If Iran is putting mines in the water or otherwise threatening American commercial shipping or American forces, we will shoot to destroy, no hesitation — just like the drug boats in the Caribbean,” — Pete Hegseth, Defense Secretary
- “Minelaying is a lot easier than minesweeping, so you can literally push these things off the back of a speedboat,” — Emma Salisbury, Foreign Policy Research Institute
What’s Next
The Navy will keep unmanned scanning while additional littoral combat ships arrive. Congressional oversight of the six-month estimate is expected, and allied nations discuss post-war mine-clearance cooperation.
