Building the Shipyards the Nation Needs

The Navy's four public shipyards -- Norfolk Naval Shipyard (NNSY), Portsmouth Naval Shipyard (PNSY), Puget Sound Naval Shipyard and Intermediate Maintenance Facility (PSNS&IMF), and Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility (PHNSY&IMF) --  perform a vital role in national defense by executing maintenance on submarines and aircraft carriers in order to provide combat-ready ships to the fleet.

Originally designed and built in the 19th and 20th centuries to build sail- and conventionally-powered ships, the Navy's public shipyards are not efficiently configured to maintain and modernize nuclear-powered aircraft carriers and submarines. With the Navy's needed focus on operations, the aging shipyards have been unable to adequately sustain and optimize their facilities, utilities, dry docks, equipment and information technology infrastructure. These inefficiencies and obsolete facilities result in higher maintenance costs, schedule risks and reliability issues.

To create the shipyards that our nation needs requires making significant investments to modernize dry docks, optimize industrial processes and modernize standard equipment to bring these critical industrial sites to modern standards.

The Navy established the Shipyard Infrastructure Optimization Program (SIOP) program office in May 2018. SIOP is a centrally-managed program led by Naval Sea Systems Command (NAVSEA), with support from Naval Facilities Engineering Command (NAVFAC) and Commander, Navy Installations Command (CNIC). NAVSEA is the operating agent and the technical authority for all four shipyards, executing the capital equipment program while NAVFAC provides facilities engineering and construction programs, supports environmental and compliance requirements and retains head-of-contracting-activity authority for facilities and dry dock investments. CNIC is the Navy's shore integrator and directs the Navy's shore environmental program.

The Navy will ensure that the optimization process fully integrates environmental considerations including natural and cultural resources, water and air quality, and more. During the development of individual shipyard plans, the Navy will develop alternatives for assessment under the National Environmental Policy Act (NEPA), Endangered Species Act (ESA) and the National Historic Preservation Act (NHPA). The Navy will work with stakeholders as part of the decision-making process and will conduct all appropriate NEPA, natural resource and NHPA analyses; agency and government-to-government consultations and public engagement and obtain all required permits to ensure a proactive approach to environmental protection.
