CIMSEC – The Navy recently issued Change 1 to one of its key new doctrine books, Navy Warfare Publication 3, Fleet Warfare. The change was issued to update the definitions of a number of key terms to keep them in accordance with joint doctrine. The issuing command, the Navy Warfare Development Center, says “Ultimately, Change 1 to NWP-3 enhances fleet-centric warfighting effectiveness through establishing a framework for the execution of fleet warfare at the operational level of warfare.” Certainly there is an advantage to maintaining consistency across the services in the definition of terms, but NWP-3’s contribution to warfighting effectiveness is less than it could be due to its generic approach to the subject. Granted, it is an unclassified publication, but nonetheless, it could have offered more practical detail on the evolving nature of the Navy’s approach to warfighting. An unclassified practical framework would be vital to operationalizing the Navy’s renewed emphasis on fleet-level warfare.
