The National Strategy on the Marine Transportation System (2023-2028) was initiated by an ad hoc interagency development team in January 2022. The 2023 National Strategy replaces the 2017 National Strategy and provides strategic guidance to the Federal interagency partnership to enhance the Federal understanding and support of the marine transportation system (MTS) under five priority areas. The Strategy went through interagency reviews, and was approved by the CMTS Coordinating Board before being signed by Transportation Secretary, Pete Buttigieg on March 3, 2023.
