The U.S. Maritime Administration issued a new advisory valid through November 2020 regarding commercial shipping in areas including the Persian Gulf and Strait of Hormuz which noted that “multiple maritime threats have been reported in the geographic areas described above. Heightened military activity and increased political tensions in this region continue to pose serious threats to commercial vessels. Associated with these threats is a potential for miscalculation or misidentification that could lead to aggressive actions”. The advisory went on to caution that “Vessels operating in the Persian Gulf, Strait of Hormuz, and Gulf of Oman may also encounter GPS interference, bridge-to-bridge communications spoofing, and/or other communications jamming with little to no warning. Vessels have also reported bridge-to-bridge communications from unknown entities falsely claiming to be U.S. or coalition warships”.
