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. COMDTINST M5000.3

Answer: (A)

The key issue is how radio communications with foreign men-of-war in United States waters are governed. The Basic Operational Communications Doctrine, NWP 6-01, provides the framework for all naval radio communications, including procedures, security, and interoperability when foreign ships operate in U.S. waters. It outlines how contact is established, what language and call signs are used, which channels or frequencies apply, and how coordination occurs with Coast Guard and other authorities to keep operations safe and orderly. The other options address more specific or different topics—foreign port calls pertain to when foreign vessels enter ports, the Public Affairs Manual deals with media and public relations, and the remaining instruction covers other areas not focused on foreign naval radio operations in U.S. waters.
