US Navy begins Hormuz mine clearing; Iran disputes transit
Two US destroyers enter the Strait of Hormuz to clear Iranian sea mines
🛡️National Security🌍Foreign Policy🏢Legislative Process
On April 11, 2026, the USS Frank E. Peterson (DDG 121) and USS Michael Murphy (DDG 112) became the first U.S. surface warships to transit the Strait of Hormuz since Iran declared the waterway closed on March 4. CENTCOM Admiral Brad Cooper announced the crossing and said the Navy was establishing a new passage that it would share with the commercial shipping industry soon.
Additional U.S. forces, including specialized underwater drone systems designed for mine detection and neutralization, were set to join the operation in coming days. Military sources described this as a multi-phase clearance effort, not a completed operation.
The transit happened the same day that U.S.-Iran ceasefire talks in Islamabad collapsed after 21 hours, leaving the conflict without a diplomatic off-ramp. Trump had already threatened to impose a naval blockade of the strait if negotiations failed, and the mine-clearing operation appeared to be the military enforcement step following that failure.
Iran's IRGC Navy immediately disputed the U.S. account of the transit. Iranian state sources claimed IRGC forces launched a drone toward the American ships and forced them to turn back before completing a full crossing, with Iran's Foreign Ministry spokesperson strongly denying that the ships made it through.
The IRGC Navy issued a direct warning that any attempt by military vessels to pass through the Strait would be dealt with severely, and passage would be granted only to civilian vessels under specific conditions. International media reported both sides' statements without being able to resolve the contradiction.
The conflicting accounts left journalists, lawmakers, and markets with no independent way to verify what actually happened. CENTCOM released no video or photographic evidence of the transit; Iran's state media reported the ships were repelled.
Iran began laying sea mines in the Strait of Hormuz after U.S. and Israeli airstrikes killed Supreme Leader Ali Khamenei on February 28, 2026. Iran declared the strait fully closed to commercial and military shipping on March 4, cutting off the primary export route for Iraq, Saudi Arabia, Kuwait, the UAE, and Qatar.
U.S. officials confirmed at least 12 Iranian-manufactured Maham 3 and Maham 7 limpet mines in the strait. Limpet mines clamp to the hulls of ships, while influence mines sit on the seafloor and detonate based on magnetic or acoustic signatures.
The Strait carries roughly 20 million barrels of crude and petroleum products per day — about 20% of all global seaborne oil trade and a larger share of liquefied natural gas shipments. Saudi Arabia, Iraq, Kuwait, the UAE, and Qatar all export through the strait.
Economic analysts documented supply disruptions since March 4, and analyzed market restructuring. The United States controls the reopening timeline — not the countries that depend on the strait most. That gives Washington unusual leverage over global energy prices.

What you can do
1
civic action
Contact your House representative about the War Powers vote
The War Powers Resolution's 60-day clock expires around May 1, 2026. Congress has declined to pass a resolution ending Trump's Iran operations but has also not formally authorized them. Your representative can push for a formal authorization vote before the clock runs out.
Hello, my name is [NAME] and I'm a constituent from [CITY/ZIP]. I'm calling about the War Powers Resolution and the Iran conflict. The 60-day clock from Trump's March 2 notification expires around May 1, and Congress has still not formally voted to authorize these operations.
Key concerns:
- Two U.S. destroyers conducted mine-clearing operations in the Strait of Hormuz on April 11 without specific congressional authorization
- The House voted only 212-219 to reject a resolution ending operations — that's a failed constraint vote, not an authorization
- The 60-day clock expires in under three weeks
Specific request: Will Representative [NAME] support a formal authorization vote before May 1, and request a classified briefing from CENTCOM on the rules of engagement for the Hormuz mine-clearing mission?

civic action
Contact your Senator ahead of the Senate war powers vote
The Senate returns from recess on April 13, and Minority Leader Schumer pledged to force a floor vote on an Iran war powers resolution. Your senator can vote to require congressional authorization for continued military operations. The Senate previously blocked a similar resolution 47-53, but the mine-clearing operation represents a new escalation.
Hello, my name is [NAME] and I'm a constituent from [CITY/ZIP]. The Senate is back in session starting April 13, and I understand a vote on the Iran War Powers Resolution is planned. I'm calling about U.S. military operations in the Strait of Hormuz.
Key concerns:
- The Senate previously voted 47-53 to block a war powers resolution on March 4
- Since that vote, the U.S. began mine-clearing operations in the Strait of Hormuz without specific congressional authorization
- 20% of global oil trade passes through the strait; this conflict's expansion affects energy costs for every American
Specific request: I'd like Senator [NAME] to support the War Powers Resolution vote the week of April 13 and require the president to obtain congressional authorization before conducting additional offensive operations in the strait.
