Rear Adm. Ronald A. Boxall, Director, Surface Warfare (N96)
OPNAV N96, the Surface Warfare Directorate, is responsible for the determination of force levels, shipboard and related support requirements and major features of programs involving weapon systems, cruisers, destroyers, frigates, command ships, patrol craft, and littoral combat ships. In addition, N96 plans, prepares, and executes as related to those missions. N96 serves as N9’s principal advisor for afloat anti-terrorism/force protection (ATFP) and chemical, biological, radiological and nuclear (CBRN) issues related to readiness, safety, survivability, training and preparation for war of the above surface forces. As such, N96 serves as N9’s representative in all matters related to afloat ATFP and CBRN readiness with other governmental agencies and produces assessments for all related Joint Capability Areas under the Sea Strike, Sea Shield and Sea Basing pillars. Because the organization is the Executive Agent for the Navy’s chemical, biological, and defense (CBD) programs as well as being the resource sponsor for Afloat Force Protection, they recognize needs and develop and evaluate plans to meet current and long-range strategic goals for enhanced ATP and CBRN readiness.
