US military warns Iranian oil tanker STARK 1 amid strike near Kharg Island

US Central Command forces struck a vessel near Kharg Island after issuing warnings to the Iranian oil tanker STARK 1, escalating a naval blockade that has already sent Brent crude above $85 per barrel. The action marks one of the most direct confrontations between US and Iranian maritime interests in years, centered on the tiny island that handles roughly 90% of Iran’s crude oil exports.

The strike follows CENTCOM’s resumption of its naval blockade on July 14, 2026, targeting vessels transiting to and from Iranian ports. Within the first 24 hours, the Curacao-flagged tanker M/T Belma was disabled by US Hellfire missiles after ignoring repeated warnings as it attempted to breach the blockade.

What happened near Kharg Island

When CENTCOM reimposed its blockade, two compliant vessels were successfully redirected without incident. The Belma was not so cooperative.

On July 15, after the tanker ignored multiple warnings, US forces fired Hellfire missiles to disable it. The ship was attempting to reach Kharg Island, which processes approximately 950 million barrels of Iranian crude per year.

The STARK 1, an Iranian-flagged crude tanker owned by the National Iranian Tanker Company, was also warned during operations in the area. NITC, the state-owned shipping firm, has been under international sanctions, and the STARK 1 has been tracked carrying laden shipments of Iranian oil in the region.

The blockade’s reimposition came in response to Iranian attacks on commercial shipping, which effectively broke down previously established ceasefires. CENTCOM framed its actions as enforcement measures designed to protect freedom of navigation and respond to Iran’s provocations against civilian maritime traffic.

Oil markets feel the pressure

Brent crude surged above $85 per barrel as the confrontation unfolded. Roughly one-fifth of global petroleum consumption passes through the Strait of Hormuz daily.

The broader geopolitical picture

The name STARK itself carries historical weight: the USS Stark was struck by Iraqi missiles in 1987 during the Iran-Iraq War tanker conflicts, killing 37 American sailors.

The sanctions regime already targeting NITC means these tankers operate in a gray zone of international commerce, often relying on ship-to-ship transfers and flag-of-convenience arrangements to move oil.
