U.S. Navy Initiates Mine Clearance in Strait of Hormuz Amid Tensions with Iran

On April 11, 2026, the U.S. Navy began operations to clear sea mines from the Strait of Hormuz, a vital maritime corridor for global oil shipments. The guided-missile destroyers USS Frank E. Petersen Jr. and USS Michael Murphy transited the strait and entered the Arabian Gulf as part of this mission.

U.S. Central Command (CENTCOM) stated that the operation aims to ensure the strait is free of sea mines previously laid by Iran's Islamic Revolutionary Guard Corps (IRGC). Admiral Brad Cooper, commander of CENTCOM, emphasized the importance of establishing a safe passage to encourage the free flow of commerce.

The IRGC reportedly issued warnings to the U.S. destroyers during their transit. According to a radio conversation recorded by a civilian ship, the IRGC stated, "This is the last warning." The U.S. ship responded, "Passage in accordance with international law. No challenge is intended to you, and I intend to abide by rules of our government's ceasefire."

Iranian media reported that the destroyers turned around after being confronted by the IRGC, which allegedly launched a drone in their direction. The IRGC also warned that any attempt by military ships to cross the strait would be met with a "firm and forceful response."

The Strait of Hormuz is a strategic chokepoint through which approximately 20% of the world's oil passes. Its control has been a focal point in the ongoing tensions between the U.S. and Iran. The U.S. military's mine clearance operations are part of broader efforts to secure this critical passage and ensure the uninterrupted flow of global energy supplies.
