What is the designation for submarines in boat naming conventions?

The designation for submarines in naming conventions is "SS." This prefix stands for "Submersible Ship" and has been widely adopted by naval organizations, particularly the United States Navy, for identifying submarines. The "SS" designation effectively communicates the vessel's capabilities and purpose as a submarine, distinguishing it from other types of naval ships.

In the context of naval nomenclature, each prefix has specific meanings. For instance, "SB" is typically not used for submarines but can refer to smaller craft or boats. "SG" does not designate submarines and is associated more with specific types of vessels or missions. Similarly, "SM" can refer to different classes of ships but is not the standard designation for submarines. The clarity of the "SS" designation allows for easier identification and understanding of naval assets, both for operational purposes and for those interacting with military forces.
