Original alert on 11 March

Description

A Merchant Vessel was struck by an unknown projectile while transiting the Strait of Hormuz, causing a fire aboard the vessel. The incident prompted an investigation by authorities.

Key findings

The fact that the projectile caused a fire aboard suggests either a direct impact with sufficient kinetic energy or potentially an explosive warhead, indicating sophisticated weaponry rather than small arms fire. The timing and location of this attack, targeting a vessel in transit rather than at anchor, demonstrates tactical planning and potentially real-time tracking capabilities by the attackers.

Recommendations

The Persian Gulf and Strait of Hormuz are considered critical risk
As per the US Maritime Administration (MARAD) Alert 2026-001A, vessels are advised to maintain a minimum 30 nautical mile standoff from US military vessels operating in the Strait of Hormuz, Persian Gulf, Gulf of Oman, and Arabian Sea due to ongoing military operations and potential retaliatory action.
