Russian Oil Tanker Employs Deceptive Tactics in Delivery to Cuba Amid U.S. Sanctions
WASHINGTON, D.C. — A Russian oil tanker, believed to be delivering fuel to Cuba, has been detected off the U.S. East Coast engaging in covert maritime maneuvers that suggest deliberate efforts to evade American sanctions. According to maritime intelligence firm Windward, the vessel, named Sea Horse, employed “dark fleet” tactics including signal manipulation and offshore ship-to-ship cargo transfers, raising concerns about the enforcement of U.S. policies targeting Cuba’s fuel supplies.
MarineTraffic data indicates the Sea Horse was located near the U.S. coastline on February 24 with its Automatic Identification System (AIS) signal marked as “roaming,” a common method used by vessels to obscure their true location and intentions. Initially, the tanker broadcast Havana as its destination on February 7, but later shifted its signals to suggest a port in Hong Kong, further complicating tracking efforts.
These deceptive practices come in the wake of heightened U.S. pressure on Cuba’s energy imports. On January 29, President Donald Trump signed an executive order declaring a national emergency concerning Cuba, authorizing tariffs on imports from countries supplying oil to the island nation. This move aligns with broader U.S. efforts to disrupt fuel deliveries to Cuba, including targeting third-party nations involved in the supply chain and detaining Venezuelan leader Nicolás Maduro, a key ally of Havana.
Windward’s analysis highlights the use of offshore ship-to-ship transfers near Cyprus, a tactic designed to mask the origin and destination of cargoes, complicating enforcement by authorities such as the U.S. Customs and Border Protection and the U.S. Coast Guard. These transfers allow tankers to avoid direct port calls that would trigger inspections or sanctions.
Experts note that the Sea Horse’s activities reflect a growing trend among sanctioned entities to employ “dark fleet” strategies, which include disabling or manipulating AIS transponders, falsifying voyage data, and conducting transfers in international waters. Such tactics pose significant challenges to maritime security and regulatory agencies tasked with upholding international sanctions.
The U.S. government’s intensified focus on Cuba’s fuel supply is part of a broader geopolitical strategy aimed at curbing the influence of Russia and its allies in the Western Hemisphere. The recent detection of the Sea Horse underscores the complexities of enforcing sanctions in an era of sophisticated maritime subterfuge.

As tensions continue to rise, agencies including the Department of Homeland Security remain vigilant in monitoring maritime traffic to prevent illicit shipments and uphold U.S. national security interests.
