What is one mission of the SSBN submarines?

The mission of SSBN (Ship, Submersible, Ballistic, Nuclear) submarines is primarily focused on ballistic missile launch. These submarines are designed to carry and launch intercontinental ballistic missiles (ICBMs), which are a critical component of the United States’ strategic nuclear deterrent. The ability to remain submerged and undetected allows SSBNs to provide a secure and survivable strike capability, ensuring that the United States can respond to nuclear threats and maintain a strong deterrent posture.

The function of launching ballistic missiles is centered around strategic deterrence, meaning these submarines contribute to national security by discouraging potential adversaries from launching an attack due to the guarantee of retaliation. Therefore, the emphasis on ballistic missile launch aligns directly with the strategic role SSBNs play in the U.S. Navy's defense strategy.
