SSBN

An SSBN, or Ship, Submersible, Ballistic, Nuclear, is a type of submarine designed to carry and launch nuclear missiles, serving as a strategic nuclear deterrent. These submarines stay submerged for long periods, making them hard to detect and providing a secure, mobile platform for a nation's most powerful weapons. They operate silently underwater and are a key part of a country's defense strategy, ensuring that in times of conflict, there is a credible threat of nuclear retaliation. In essence, SSBNs are stealthy underwater nuclear missile carriers that enhance national security through deterrence.
