USS Nautilus (first nuclear submarine)

The USS Nautilus, launched in 1954, was the world's first nuclear-powered submarine and a significant advancement in naval technology. Unlike traditional submarines that relied on diesel engines and needed to surface frequently, the Nautilus used a nuclear reactor for propulsion, allowing it to operate underwater for extended periods without resurfacing. This capability revolutionized submarine warfare and exploration, enabling longer missions and greater stealth. The Nautilus set numerous records, including the first submarine to reach the North Pole under the ice in 1958, showcasing the potential of nuclear power in naval operations. It played a crucial role during the Cold War era.
