Ballistic Missile Submarine (SSBN)

A Ballistic Missile Submarine (SSBN) is a highly secure naval vessel designed to carry and launch long-range nuclear missiles while submerged. It serves as a key component of a country's strategic nuclear deterrent, ensuring second-strike capability even during conflict. These submarines are stealthy, capable of remaining hidden beneath the ocean surface for extended periods, and their missile launchers are protected within the submarine’s hull. The SSBN’s primary role is to provide a survivable and credible nuclear deterrent, helping prevent nuclear conflict through the assurance of assured retaliation.
