Who establishes COMSEC allowances for COMSEC equipment?

The establishment of COMSEC allowances for COMSEC equipment is the responsibility of the Chief of Naval Operations (CNO). This authority aligns with the CNO's role in overseeing operational readiness and ensuring that communications security measures are properly implemented across the navy. The CNO's directives form a crucial part of the planning and resource allocation necessary for maintaining effective COMSEC practices within naval operations.

The other organizations play significant roles in the overall communications security protocol and management. For instance, the National Security Agency (NSA) primarily focuses on gathering intelligence and safeguarding national security information, while the U.S. Department of Defense (DoD) provides overarching policies and budgetary support across military branches. The Navy Communications and Information Systems (NCMS) may address issues of communications systems management, but the final determination of allowances for specific COMSEC equipment falls under the purview of the CNO.
