Consistent with Presidential Policy Directive 18: Maritime Security (PPD-18) and the National Strategy for Maritime Security (NSMS), the National Maritime Domain Awareness Plan (NMDAP) merges and supersedes the National Plan to Achieve Maritime Domain Awareness of 2005 and the Global Maritime Intelligence Integration Plan of 2005. It establishes the foundation for the effective understanding of potential and actual maritime threats and challenges by promoting favorable conditions for integrating and sharing information, including intelligence, to inform decision-makers.
