Audience:On January 21, 1954, the U.S.S. Nautilus, the world’s first submarine powered by nuclear energy, was launched on the Thames River in Groton, Connecticut. The technology of the Nautilus would change naval exploration and warfare forever.The Nautilus was powered by a nuclear reactor. The reactor produced heat that was used to boil water. Steam from the boiling water drove steam turbines that created electricity. Electricity was used to propel the submarine, maintain living conditions such as temperature and air quality, and even support desalination processes.Unlike engines that run on fossil fuels, nuclear reactors do not require frequent refueling or air. This means the Nautilus and other nuclear-powered submarines could remain underwater for much, much longer time periods than traditional submarines. In fact, the Nautilus’ first voyage became what was then the world’s longest submarine trip—from New London, Connecticut, to San Juan, Puerto Rico.Nuclear reactors also create an enormous amount of power. This allowed the Nautilus and other nuclear-powered submarines to quickly respond to threats. Nuclear-powered submarines can maneuver and change depth much more easily than traditional submarines.
