A new Navy policy recognizes the electromagnetic spectrum as a warfighting domain “on par with sea, land, air, space and cyber.”

The policy pushes “an enterprise approach to all activities necessary” for Navy electromagnetic spectrum (EMS) operations, including the department”s “roles and responsibilities for developing, implementing, managing, and evaluating Electromagnetic Battlespace programs, policies, procedures, and controls to enable DON superiority,” according to the document. The change, which took effect Oct. 5, was announced publicly on Oct. 22.

The EMS enterprise, as defined in the new policy, includes “all electronic systems, subsystems, devices, and equipment that depend on the use of spectrum to properly accomplish their function” whether acquired or procured from commercial companies.
