In a worrying development for global maritime security, unmanned naval drones have been implicated in at least two recent assaults on oil tankers navigating the Gulf region. These attacks have occurred amid the intensifying conflict involving the United States, Israel, and Iran, underscoring a growing and sophisticated threat to one of the world’s most crucial shipping corridors. Experts and maritime authorities have identified these incidents as a sign of evolving tactics that could destabilize energy supplies and international trade routes.
The use of explosive-laden unmanned surface vessels, a tactic that has gained prominence in recent conflicts such as Ukraine’s war against Russia, has now surfaced in the Gulf. This method involves small, remote-controlled boats packed with explosives, capable of inflicting significant damage on large commercial vessels. The timing is particularly significant as Iran has issued warnings about potentially blocking oil shipments passing through the Strait of Hormuz, a narrow but vital chokepoint responsible for the transit of nearly 20% of the world’s oil supply.
The first recorded attack involving a sea-based drone took place on March 1, when the crude oil tanker MKD VYOM was targeted approximately 44 nautical miles off the coast of Oman. The assault resulted in the tragic death of one crew member and caused a fire in the ship’s engine room. The United Kingdom Maritime Trade Operations (UKMTO) agency confirmed that an unmanned surface vessel struck the Marshall Islands-flagged tanker just above the waterline, triggering an explosion that severely damaged the vessel. This incident sent shockwaves through the maritime community, raising alarms about the vulnerability of commercial shipping to such unconventional threats.
Shortly after, another attack occurred near Iraq’s Khor al Zubair port, where a small vessel collided with the Bahamas-flagged crude oil tanker Sonangol Namibe. The company operating the tanker, Sonangol Marine Services, assured that all 23 crew members aboard remained unharmed, though it refrained from specifying the nature of the attacking vessel due to an ongoing investigation. Video footage circulating online depicted a small, speedboat-like object rapidly approaching and striking the tanker, followed by a powerful explosion that released thick plumes of smoke into the sky. Maritime security experts based in the United Kingdom identified the object as a naval drone that detonated upon impact.
Analysts specializing in maritime security have pointed fingers at Iran for the Sonangol Namibe incident. Robert Peters, a security consultant, highlighted Iran’s previous demonstrations of naval drone capabilities during military parades and noted the attack’s timing closely followed an assault by Iran’s Islamic Revolutionary Guard Corps (IRGC) on an American oil tanker in the northern Persian Gulf. The IRGC claimed responsibility for that strike, reportedly using missiles to set the vessel ablaze, Iranian semi-official media. Tehran has since issued stark warnings about the potential for oil prices to soar to $200 per barrel, as its forces continue to target commercial shipping and disrupt traffic through the Strait of Hormuz, which has nearly ground to a halt.
Despite mounting suspicions, definitive proof linking Iran directly to these naval drone attacks remains elusive. The Iranian mission to the United Nations in New York has not responded to inquiries seeking clarification. If confirmed, this would mark the first known occasion where Iran has employed naval drones in direct attacks against commercial shipping. Previously, Iran-aligned Houthi militants in Yemen have used similar drone boats to target vessels in the Red Sea, signaling a broader regional trend toward the militarization of unmanned maritime technology.
Experts emphasize that sea drones carry a more substantial explosive payload compared to their aerial counterparts, potentially rivaling ballistic missiles in destructive power. While aerial drones primarily pose a threat by targeting crew members from above, naval drones have the capability to disable ships by striking critical areas, effectively immobilizing them. This vulnerability leaves vessels exposed to further attacks or capture. The strategic implications are profound, as immobilized oil tankers could severely disrupt global energy supplies and escalate tensions in an already volatile region.
