The Strait of Hormuz, a critical waterway for international oil trade, remains highly vulnerable to various threats despite the presence of naval escorts. According to the International Maritime Organization (IMO) chief, Arsenio Domínguez, the combination of extensive mine threats, ballistic and cruise-missile attacks, swarming unmanned aerial vehicles (UAVs), and fast-attack craft swarms overwhelms the protective capabilities of naval escorts.

The geographic constraints of the strait, which narrows to 21 miles at its tightest point, further exacerbate the risk. Limited escort capacity, with a single U.S. destroyer only able to protect one or two tankers at a time, and the logistical challenges of sustained operations in a high-threat zone, reduce the effectiveness of naval escorts. The uncertainty of Iranian intent, with repeated threats to attack passing ships, adds to the volatility of the situation.

Air-defence gaps, requiring continuous fighter cover that is logistically demanding, and the lack of a unified international coalition with adequate resources, compound the difficulties in ensuring safe passage. The IMO chief’s assessment reflects the complexity and severity of the threats, underscoring that naval escorts alone cannot guarantee safe passage through the Strait of Hormuz.
