OPNAV E3/Spectrum Responsibilities

• OPNAV N2N6 (Information Warfare) is the lead for– USN E3/Spectrum policy and requirements

– Electromagnetic Maneuver Warfare requirements

• Sponsor E3 Program for the Navy in conjunction with Systems Commands (e.g., Naval Sea Systems Command, and Naval Air Systems Command)

– Electromagnetic Interference (EMI) problem prevention & resolution

– Fleet engineering tools for spectrum management

– Nuclear Electromagnetic Pulse (EMP) Survivability Program

• Sponsor Operational Spectrum Management via the Navy and Marine Corps Spectrum Center (NMSC)

– Procure, coordinate, register, assign, and protect radio frequencies for Research and Development Test and Evaluation (RDT&E) and operational use

– Ensure review, coordination, and approval of all spectrum certification requests

– Resource the annual National Telecommunication and Information Administration (NTIA) spectrum fees
