The National Port Readiness Network (NPRN) consists of Strategic Commercial Seaports able to support force deployment during contingencies and other defense emergencies. Nine federal agencies and organizations, USDOT/Maritime Administration (MARAD), U.S. Army Corps of Engineers (USACE), Surface Deployment and Distribution Command (SDDC), U.S. Coast Guard (USCG), Military Sealift Command (MSC), U.S. Army Forces Command (USFORSCOM), Transportation Security Administration (TSA), U.S. Northern Command (USNORTHCOM), and U.S. Transportation Command (USTRANSCOM) are responsible for providing guidance to the NPRN program and for supporting the secure movement of military forces through U.S. ports. This dataset includes all 18 commercial ports that currently belong to the NPRN. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529080 This data provides users with information about the strategic ports and approximate locations and attributes for national and regional analysis application.

Users are advised to read the rest of the metadata record carefully for additional details. The Commercial Strategic Seaports database is created as a point-shapefile based on approximate location of strategic ports. Domestic and foreign tonnages reported for each port were provided by the U.S. Army Corps of Engineers and are from their annual “Principal Ports” reporting. asNeeded Jake Tsubota U.S. Maritime Administration (MARAD) Economist 1200 New Jersey Ave. SE Washington DC 20590 United States jake.tsubota@dot.gov custodian
