Nuclear-powered submarines are advanced military vessels that use nuclear reactors to generate power. This technology allows them to operate underwater for extended periods without needing to surface for fuel, making them highly strategic assets for naval forces. They can travel at high speeds and remain submerged for months, enhancing their stealth and operational capabilities. These submarines are equipped with various systems, including torpedoes and ballistic missiles, enabling them to perform a range of missions, from surveillance to deterrence. The use of nuclear power also means they produce fewer emissions compared to conventional submarines, contributing to their efficiency and effectiveness in modern warfare.
