: [ 🔗 클릭‼️ ] (.)(,,),,.(,,) [] Inside a Navy Submarine Navigating the Arctic A Times photojournalist embarked on a nuclear-powered attack sub to see how the Pentagon is training for a potential war below the frozen sea. U.S. Navy sailors aboard nuclear-powered submarines have long trained in the Arctic, learning to hunt their Russian counterparts in case of war. But America’s sub force is sharpening its combat skills at the edge of the world as Russia expands military operations there. Operating a sub in the Arctic is especially challenging. First, navigation. In some areas, shallow waters force the crew to thread a narrow path between twin threats: the ice above and the ocean floor below. Second, water condensation that comes from the freezing ocean waters against the boat’s hull creates the risk of small electrical fires on the submarine. Being “underway” on a sub, the sailors say, is like working in a small office space with no windows, no way to leave, no Wi-Fi and zero cell service. Crucial military decisions are made entirely on the boat, with no outside communication. Life there is rugged. No showers. No running water. The outside air dips to 40 degrees below zero. U.S. Navy submarines run classified missions around the world every single day. Attack boats like the Hampton might collect intelligence on enemy warships or eavesdrop on unfriendly governments, while much larger ballistic missile submarines stay submerged for 90 days at a time, carrying enough nuclear warheads to destroy entire countries. , .: [email protected]
