Nuclear submarines are advanced underwater vessels powered by nuclear reactors. This technology allows them to operate for long periods without needing to surface for fuel, making them ideal for stealthy military operations. They can travel at high speeds and remain submerged for months, enhancing their strategic capabilities. These submarines are equipped with various weapons systems, including ballistic missiles and torpedoes, enabling them to perform multiple roles, from deterrence to combat. Their design includes advanced sonar and navigation systems, ensuring they can navigate and operate effectively in diverse underwater environments.
