"This Plan provides the context to understand the importance of MDA [maritime domain awareness] to maritime security and why it is imperative to enhance MDA. It will empower the U.S. Government to understand the characteristics of the current maritime domain, identify the strategic approach we seek to employ, clarify our strategic and foundational priorities, and develop an implementation plan to improve MDA that enables decision-makers to perform their responsibilities consistent with Presidential Policy Directive 18 (PPD-18) and the National Strategy for Maritime Security (NSMS)."
