U.S. Central Command (CENTCOM) said the routes of 82 commercial vessels were changed between the start of the maritime blockade of Iran in April and August 28, 2026.
CENTCOM said that three vessels were stopped during the same period and that two were boarded to inspect compliance with the maritime blockade.
The military maritime blockade was imposed in April 2026 after the war between the United States and Israel began on February 28 and the first ceasefire talks ended without an agreement.
Blockade against the Strait of Hormuz
The blockade was launched in response to Iran's Islamic Revolutionary Guard Corps closing the Strait of Hormuz. The operation involved encircling Iran's coastline and ports with a force comprising more than 20 warships and approximately 50,000 troops, with the aim of completely halting Tehran's crude oil exports.
During this period, numerous commercial vessels, as well as oil tankers linked to Iran, were forced to change course.
After the June agreement
Although a temporary memorandum of understanding was reached in June 2026, the agreement broke down because Iran kept the maritime passage closed and imposed a transit fee.
Washington then resumed the blockade and moved the operation into a more intensive phase aimed at reducing oil sales to zero and paralyzing Iran's energy sector.
