National Plan to Achieve Maritime Domain Awareness for the National Strategy for Maritime Security [open pdf - 492KB]
"The National Plan to Achieve Maritime Domain Awareness lays the foundation for an effective understanding of anything associated with the Maritime Domain that could impact the security, safety, economy, or environment of the United States and identifying threats as early and as distant from our shores as possible. This Plan serves to unify United States Government and support international efforts to achieve MDA across the Federal government, with the private sector and civil authorities within the United States, and with our allies and partners. It directs close coordination of a broad range of federal departments and agencies for this lasting endeavor. Implementation of this Plan will be conducted under the oversight of an interagency implementation team."
