WASHINGTON — The Pentagon informed Congress on Tuesday that clearing naval mines from the Strait of Hormuz following a potential conflict with Iran could require up to six months, with operations unlikely to commence until after hostilities cease.

Defense officials outlined the logistical challenges in a briefing to lawmakers, emphasizing the strategic importance of the waterway for global energy supplies. The Strait of Hormuz serves as a critical chokepoint for international oil shipments, with approximately one-fifth of the world's petroleum passing through the narrow passage daily.

The assessment comes amid heightened tensions between the United States and Iran, with military planners preparing for scenarios involving asymmetric warfare in the Persian Gulf. Iranian military capabilities in the region include extensive stockpiles of naval mines, which experts describe as a primary threat to commercial and naval vessels.

"The complexity of the environment and the volume of potential ordnance mean that a full clearance operation would be a prolonged effort," a senior defense official stated during the closed-door session. The official declined to specify the exact number of mines or the types of equipment required for the operation.

The six-month timeline reflects the need to ensure safe passage for commercial shipping and the restoration of normal maritime traffic. Defense planners noted that any premature attempt to clear mines during active combat would expose personnel to significant risk and could compromise the effectiveness of the operation.

Iranian military doctrine has long emphasized the use of mines as a force multiplier against superior naval powers. Previous exercises and statements from Iranian commanders have highlighted their ability to deploy mines rapidly in the strait, potentially disrupting global trade within hours of a conflict's onset.

The Pentagon's assessment does not address the immediate impact of a potential conflict on oil prices or the broader economic consequences of a prolonged closure of the strait. Energy analysts have warned that even a temporary disruption could send global fuel prices soaring, with ripple effects across international markets.

Lawmakers questioned officials on contingency plans for alternative shipping routes and the potential for international cooperation in mine-clearing efforts. The United States has historically coordinated with regional allies on maritime security, but the specifics of such collaboration in a post-conflict scenario remain unclear.

The briefing also touched on the broader implications of a prolonged conflict in the Persian Gulf, including the potential for regional escalation and the involvement of other state and non-state actors. Defense officials stressed that the mine-clearing timeline is one of many factors in the overall strategic planning process.

As of Tuesday evening, no official timeline for a potential conflict has been announced, and diplomatic efforts to de-escalate tensions continue. The Pentagon's assessment serves as a warning to policymakers about the long-term consequences of military action in the region, even after the immediate fighting has ended.

The situation remains fluid, with ongoing diplomatic negotiations and military posturing shaping the outlook for the Strait of Hormuz. Further updates on the Pentagon's planning and Iran's military posture are expected as the situation develops.
