Satellite imagery has depicted what appears to be at least three United States military vessels surrounding Trinidad—one off its northern coast, and two in the Gulf of Paria.

European Space Agency (ESA) satellite Sentinel-2 L1C on Tuesday captured one large vessel, believed by experts to be the USS Iwo Jima (LHD-7), a Wasp-class amphibious assault ship deployed by the US Navy to the Caribbean earlier this year, situated just north of Diego Martin, 41 miles from Trinidad’s northern coast, and 45 from Venezuela.

The Iwo Jima is a Landing Heli­copter Dock (LHD)—a type of vessel that has historically provided US Marine Corps with a means of ship-to-shore movement by helicopter, in addition to movement by landing craft.
