The Nuclear Navy refers to the branch of the United States Navy that operates submarines and aircraft carriers powered by nuclear reactors. This technology allows these vessels to remain submerged or at sea for extended periods without the need for refueling, enhancing their operational capabilities and strategic reach. Nuclear-powered ships are equipped with advanced systems that provide significant advantages in stealth and endurance. The first nuclear submarine, the USS Nautilus, was launched in 1954, marking a significant milestone in naval engineering and military strategy. Today, the Nuclear Navy plays a crucial role in national defense and global maritime operations.
