Most people watch the skies when they think about future wars. The pros? We watch the oceans. The U.S. Navy’s Virginia-class attack submarines are not flashy — you’ll never see one in a parade — but they are the quiet killers that keep adversaries awake at night. China is building more ships. Russia is making noise about hypersonics. But under the surface, the gap is huge. Our subs can stay submerged for months, hit targets from 1,000 miles away, and vanish before anyone can react. In naval warfare, invisibility is dominance. And right now, nobody on Earth does it better than the United States. #Military #USNavy #Defense
