The U.S. Navy's USS Iwo Jima (LHD-7), a Wasp-class amphibious assault ship, arrived in Puerto Rico for the first time, according to an X post shared between 4:16 p.m. and 5:15 p.m. UTC on December 19, 2025. The post, which garnered 106 likes, states the ship is designed to transport and deploy Marines, aircraft, and vehicles in amphibious and expeditionary operations and was commissioned on June 30, 2001. This development continues logistical operations at Muelle de Ponce. Separate X posts during the same 59-minute window reported a possible RQ-170 Sentinel drone sighting, with @pepislela stating verbatim: "I just saw it. It certainly flies very high and fast... I think it's an RQ-170 Sentinel 🤪 1/2." @beverstine posted: "Casual RQ-170 patch. Sentinel operating in AFSOUTH?" @SecRubio stated: "The single most serious threat to the United States from the Western Hemisphere is from transnational terrorist criminal groups, primarily focused on narcotrafficking... There's one place that doesn't cooperate - and it's the illegitimate regime in Venezuela." @AirAssets reported a B-52 airborne, stating: "I am not going to get excited...they have cried wolf too many times. B-52 Airborne." This follows the USNS Supply's arrival at Muelle de Ponce at 10 a.m. local time earlier today, as reported by @FaytuksNetwork, part of U.S. Southern Command's ongoing buildup.
