The New York Times reports:

Iran has been unable to open the Strait of Hormuz to more shipping traffic because it cannot locate all of the mines it laid in the waterway and lacks the capability to remove them, according to U.S. officials.

The development is one reason Iran has not been able to quickly comply with the Trump administration’s admonitions to let more traffic pass through the strait. It is also potentially a complicating factor as Iranian negotiators and a U.S. delegation led by Vice President JD Vance meet in Pakistan this weekend for peace talks.

Iran used small boats to mine the strait last month, soon after the United States and Israel began their war against the country. The mines, plus the threat of Iranian drone and missile attacks, slowed the number of oil tankers and other vessels passing through the strait to a trickle, driving up energy prices and providing Iran with its best leverage in the war.

Iran left a path through the strait open, allowing ships that pay a toll to pass through.

Iran’s Islamic Revolutionary Guards Corps has issued warnings that ships could collide with sea mines, and semiofficial news organizations have published charts showing safe routes.

Those routes are limited in large part because Iran mined the strait haphazardly, U.S. officials said. It is not clear that Iran recorded where it put every mine. And even when the location was recorded, some mines were placed in a way that allowed them to drift or move, according to the officials.

As with land mines, removing nautical mines is far more difficult than placing them. The U.S. military lacks robust mine removal capabilities, relying on littoral combat ships equipped with mine sweeping capabilities. Iran also does not have the capability of quickly removing mines, even the ones it planted. [Continue reading…]
