The National Port Readiness Network (NPRN) dataset is as of October 4, 2021 and is from the U.S. Maritime Administration’s (MARAD) Office of Policy and Plans, and part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS') National Transportation Atlas Database (NTAD). The NPRN consists of strategic commercial ports 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 Sea-lift 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 17 commercial ports that currently belong to the NPRN, as well as their tonnage volumes for the year 2017 (as reported by the U.S. Army Corps of Engineers).
