SSBN (Ballistic Missile Submarine)

An SSBN, or Ballistic Missile Submarine, is a specialized submarine designed for nuclear deterrence. It remains hidden beneath the ocean surface for long periods, equipped with powerful nuclear missiles capable of reaching distant targets. Its primary purpose is strategic; it serves as a floating nuclear threat that can respond to threats against a country, ensuring national security through a reliable and survivable second-strike capability. SSBNs are a key component of a country's defense strategy, providing a secure, stealthy means of maintaining nuclear deterrence over time.
