Iran has significantly reinforced military defenses on Kharg Island, including laying mines and deploying advanced air defense systems, in anticipation of a potential U.S. ground operation, according to U.S. intelligence sources.
Strategic Importance of Kharg Island
Kharg Island, located in the northeastern Persian Gulf, is critical for Iran's economy, handling approximately 90% of its crude oil exports. The island, about a third the size of Manhattan, is situated away from the Strait of Hormuz but near key Iranian oil facilities.
U.S. Considerations and Associated Risks
The Trump administration has weighed using U.S. troops to seize Kharg Island as leverage to coerce Iran into reopening the Strait of Hormuz. U.S. officials and military experts warn of significant risks, including high casualties due to Iran's layered defenses.
- Primary risks include:
- Dense defensive setups with MANPADs (shoulder-fired surface-to-air missiles).
- Anti-personnel and anti-armor mines placed around the island, including on shorelines for amphibious landing prevention.
- Proximity to the Iranian coast enabling ballistic missile and drone attacks.
Iranian Defense Buildup Details
In recent weeks, Iran has enhanced its defenses by:
- Laying traps, including mines, around the island.
- Deploying additional MANPAD systems.
- Moving extra military personnel and air defenses, such as HAWK surface-to-air missiles and Oerlikon anti-aircraft guns.
Recent U.S. Military Action
On March 13, the U.S. military struck Kharg Island, hitting 90 targets including naval mine storage facilities and missile bunkers, while avoiding oil infrastructure for "reasons of decency," as stated by President Trump.
International Reactions and Concerns
- Gulf Allies: Privately urge the U.S. against ground occupation, fearing high casualties and Iranian retaliation against their infrastructure. They prioritize dismantling Iran's ballistic missile program.
- Israel: Expressed concern that seizing Kharg could trigger attacks by Iranian drones and missiles, endangering American troops.
- Iran: Parliament speaker Mohammad Bagher Ghalibaf warned that any attempt to occupy Iranian islands would prompt relentless attacks on vital regional infrastructure.
U.S. Military Deployments and Surveillance
- Two Marine Expeditionary Units, specializing in amphibious operations, have deployed to the Middle East, with the Army's 82nd Airborne Division expected soon.
- U.S. Central Command maintains near-constant surveillance of the island, monitoring defensive changes.
- Retired Adm. James Stavridis, a CNN analyst, cautioned that Iran would aim to inflict maximum casualties on U.S. forces.
Alternative Strategies
Experts propose alternatives to a ground operation:
- An offshore blockade to disrupt oil exports without troop deployment.
- Continued strikes to degrade defenses, though ballistic missile threats persist due to proximity to Iran.
