Ballistic Missile Submarine (BMS)

A Ballistic Missile Submarine (BMS) is a naval vessel designed to quietly stay underwater for long durations while carrying powerful nuclear missiles. Its primary role is strategic deterrence, ensuring that potential adversaries know that any large-scale attack would be met with a retaliatory strike from the submerged submarine. These submarines are equipped with ballistic missiles that can be launched while underwater, making them hard to detect and very capable of providing a safe, mobile nuclear force. They operate globally, often silently, establishing a crucial part of a country's defense strategy without revealing their position.
