U.S. Military Assessment on Mine Clearance in the Strait of Hormuz

The Pentagon has informed Congress that clearing the Strait of Hormuz of mines deployed by the Iranian military could take up to six months. This operation is unlikely to commence until the ongoing U.S. war with Iran concludes. The assessment indicates that the economic repercussions of the conflict, particularly concerning oil and gasoline prices, may persist well into the year 2026 or beyond.

Reports indicate that Iran may have placed 20 or more mines in and around the Strait of Hormuz, with some being deployed remotely using GPS technology. This method complicates detection efforts, raising concerns among U.S. lawmakers from both parties. The issue of mines in the Strait is not new; discussions have been ongoing since early March 2026, when U.S. officials first suggested that small boats were used for mine deployment following the sinking of larger vessels.

Lawmakers expressed frustration over the Pentagon's assessment, which suggests a prolonged economic impact due to elevated oil prices. President Donald Trump previously claimed that Iran had either removed or was in the process of removing these mines, asserting that most Iranian "mine droppers" had been destroyed in U.S. strikes. In contrast, Iran has denied these allegations, labeling them as American propaganda. Iranian media reported that the Islamic Revolutionary Guard Corps. has issued safe passage maps for the area, indicating their awareness of the situation.

The assessment from the Pentagon has drawn criticism from both Democratic and Republican lawmakers, who are concerned about the implications for the economy and national security. The prolonged timeline for mine clearance raises questions about the effectiveness of U.S. military operations and the potential for continued instability in the region.

While the Pentagon's assessment suggests a significant number of mines have been deployed, there is a lack of clarity regarding the exact number and status of these mines. The U.S. Central Command declined to comment on the situation, and the White House has referred inquiries back to the Pentagon, leaving some gaps in public understanding of the operational challenges.
