U.S. Efforts To Prevent Iranian Mine Laying In Strait Of Hormuz Underway

A day after President Donald Trump ordered U.S. forces to destroy Iranian ships laying mines in the Strait of Hormuz, the Chairman of the Joint Chiefs of Staff on Friday said efforts to prevent mining are already underway.

The Islamic Revolutionary Guard Corp (IRGC) “has a variety of smaller Boston Whaler-size boats,” Air Force Gen. Dan Caine told reporters, including from The War Zone, during a Friday morning media briefing. “We have forces up there deterring and preventing them from continuing to [lay mines], and will continue to do so pursuant to the orders of the Secretary and the President.”

You can hear Caine’s comments on Iranian mining at the 23-minute mark in the following video.

Caine did not offer specifics about what assets are involved, when they arrived or what actions they have taken. The Pentagon and CENTCOM have declined to comment. A U.S. official, however, did provide us with some additional information.

“Iran likely placed some mines in or near the Strait at some point during the conflict,” the official told us, speaking anonymously to discuss operational details. “We’re not talking about a high volume. In fact, more than 95% of Iran’s naval mines were destroyed during Operation Epic Fury.”

U.S. forces “are actively addressing the matter using a combination of manned and unmanned capabilities to ensure passage through the Strait is safe.” The official declined to say if the U.S. is actively searching for mines already laid or provide further details. In our story yesterday, we spelled out what assets the Navy has for its surface fleet to conduct demining operations, though it remains unclear how many are in the region. You can read more about that here.

As we noted, the Independence class littoral combat ship USS Canberra is the only confirmed mine sweeper currently in CENTCOM, according to a post on the Pentagon’s image sharing site that shows the ship patrolling in the Arabian Sea.

As we have frequently reported, the IRGC has invested heavily in its fleet of small boats for decades. In addition to being armed with short-range anti-ship missiles, as well as artillery rockets and other weapons, they can also be used to lay naval mines. While the president claimed that 159 Iranian ships have been destroyed, the IRGC still has a large number of these small vessels.

War Secretary Pete Hegseth, also speaking at the briefing, said “reckless mining like that is a violation of the cease fire.” He declined to say how long it will take to clear the Strait of mines.

“We would not speculate on a timeline,” he proffered in response to a question about a Washington Post story claiming Congress was informed it could take up to six months to do so. “We feel confident in our ability, in the correct period of time, to clear any mines that we identify, and we encourage other countries to be a part of such an effort as well. But we’re tracking that very closely.”

It isn’t clear why these efforts to keep small boats from mining the Strait have not been persistent and ongoing from early in the conflict, but especially now that Iran professes control over the strategic waterway. However, Hegseth derided the IRGC as a fighting force.

“Iran’s battered military, the IRGC, specifically, has been reduced to a gang of pirates with a flag,” the secretary scowled.

Sec. Of War Pete Hegseth: "The IRGC specifically has been reduced to a gang of pirates with a flag… They know that we, the United States of America, control the flow of global shipping — and we know that they know. Their real navy is at the bottom of the Arabian Gulf." pic.twitter.com/94HNDITkMn
