The Use of Radio by Foreign Men-of-War in United States Waters is in accordance with which doctrine?

• A. Basic Operational Communications Doctrine NWP 6-01
• B. Foreign Port Calls COMDTINST 3128.1
• C. Public Affairs Manual COMDTINST M5728.2
• D. National Security Decision Directive 97

Answer: (A)

Radio communications involving foreign men-of-war in U.S. waters are governed by standardized procedures that ensure safe, clear, and secure transmissions between vessels and U.S. authorities. The Basic Operational Communications Doctrine (NWP 6-01) provides the framework for who may use the radio, how transmissions are initiated, the proper call signs and messaging formats, and the security and interoperability measures needed for international operations in U.S. waters. This makes it the appropriate reference for guiding such radio use.

The other options don’t fit this specific area: foreign port calls directives focus on visits and port procedures, the Public Affairs Manual covers media relations, and National Security Directive 97 deals with higher-level policy rather than day-to-day radio operations.
