Following the outbreak of military conflict on 28 February 2026, the U.S. Central Command (CENTCOM) initiated a naval blockade on 13 April 2026 to restrict commercial shipping to and from Iranian ports. The blockade aimed to apply strategic economic pressure on Iran, particularly by targeting Kharg Island, which handles approximately 90% of Iran’s crude oil exports.
Key Operational Metrics
- Enforcement: U.S. naval assets monitored chokepoints in the Persian Gulf and Gulf of Oman.
- Interdictions: By June 2026, forces had disabled several vessels (including the Botswana-flagged M/T Lexie) and redirected over 122 merchant ships.
- Precision Strikes: The U.S. utilized AGM-114 Hellfire missiles to disable engine rooms, a “Batesian strategy” designed to neutralize hardware while avoiding environmental disasters or hull breaches.
Recent Developments (June 2026)
- A preliminary peace accord was announced in mid-June 2026 between the U.S. and Iran.
- The agreement includes a permanent ceasefire, the removal of the U.S. naval blockade, and the reopening of the Strait of Hormuz, effective 19 June 2026.
