What is the call sign of the surface warfare commander?

The call sign of the surface warfare commander is denoted by the letter associated with this role, which is historically "_S." In naval operations, each type of warfare commander has a specific call sign used for identification and communication purposes. In this case, "S" is designated for surface warfare operations, which includes the command and control of surface ships within a naval task force or fleet.

The other call signs are appropriated for different roles within the naval structure, aligning with other domains of warfare, such as air or undersea operations. Understanding these designations is crucial for effective communication during joint or combined operations, as it aids in quick identification of the responsible commanders and their respective warfare areas.
