The USS Newport News (SSN 750), a Los Angeles-class Flight II nuclear-powered attack submarine, made a historic port visit to Iceland on July 9, 2025. This marked the first time a U.S. nuclear-powered submarine has docked on Icelandic shores. Admiral Stuart Munsch, commander of U.S. Naval Forces Europe-Africa, described the visit as an important strategic signal amid increasing competition in the Arctic region. In addition to the USS Newport News, multiple Arleigh Burke-class guided missile destroyers and other U.S. Navy vessels were observed leaving and arriving at various U.S. ports including San Diego, Norfolk, and Pearl Harbor between late June and early July 2025. Notable ships included the USS Chafee (DDG 90), USS Mustin (DDG 89), USS Bainbridge (DDG 96), USS Donald Cook (DDG 75), and USS Michael Murphy (DDG 112). Allied naval movements were also noted, such as the Portuguese Navy's Bartolomeu Dias-class frigate NRP Bartolomeu Dias arriving in Aberdeen, Scotland, and the British HMS Duncan departing Portsmouth, England. The U.S. Navy's logistical and support vessels, such as the USNS PFC Dewayne T. Williams and USNS Robert E. Peary, were active in ports including Rota, Spain, and Norfolk, Virginia. These movements reflect ongoing naval operations and strategic positioning in multiple regions including the North Atlantic and Pacific.
