Which fleet does not contain fleet ballistic submarines?

The correct answer indicates that the Black Sea Fleet does not contain fleet ballistic submarines. This is accurate because the Black Sea Fleet primarily focuses on regional security operations and does not deploy the same types of strategic assets as other fleets.

Fleet ballistic submarines are specifically associated with the strategic nuclear deterrence mission and are typically part of larger fleets that operate in open ocean environments, such as the Northern Fleet and the Pacific Fleet. These fleets have the resources and strategic requirements to house and operate such submarines effectively.

In contrast, the Black Sea Fleet operates in a more confined maritime area, dealing with operational missions that do not necessitate the deployment of ballistic missile submarines, instead focusing on surface combatants and smaller submarines more suitable for regional operations.
