Iran Fortifies Kharg Island as US Weighs Seizure — USS Tripoli and 82nd Airborne in Position

Iran lays defensive traps on its 90% oil export hub as US Marines approach on assault ship

Iran is fortifying Kharg Island in the Persian Gulf against a feared US amphibious assault, CNN reported on 26 March 2026. Kharg handles approximately 90% of Iran's crude oil exports. Tehran has laid traps, reinforced personnel, and deployed MANPADS. The same morning, Axios revealed the US is working on four specific 'final blow' options if Iran talks fail: (1) seize or blockade Kharg; (2) take Larak Island in the Strait; (3) invade Abu Musa Island; (4) block Iranian oil ships. A fifth track involves seizing or bombing Iran's HEU stockpile. The US has moved 1,000 paratroopers from the 82nd Airborne and 5,000 Marines aboard USS Tripoli toward the Gulf. Trump has not ruled out Kharg and has said Iran must 'get serious soon' or face consequences with 'NO TURNING BACK.'

Key facts

  • Kharg Island handles ~90% of Iran's crude oil exports — seizure would cripple Iranian economy

  • 1,000 paratroopers from 82nd Airborne also deployed toward region

  • Qalibaf warned: seizure would trigger 'relentless attacks' on regional state involved
