Homeland Defense: Actions Needed to Improve DOD Planning and Coordination for Maritime Operations, Report to Congressional Requesters [open pdf - 644KB]
"Recent events, such as the seaborne terrorist attack on Mumbai in 2008 and the pirate attack on the Quest in February 2011, highlight maritime threats to the United States. The maritime domain presents a range of potential security threats--including naval forces of adversary nations, piracy, and the use of vessels to smuggle people, drugs, and weapons--which could harm the United States and its interests. The Department of Defense (DOD) has also identified homeland defense as one of its highest priorities. Government Accountability Office (GAO) was asked to determine the extent to which DOD has (1) planned to conduct maritime homeland defense operations, (2) identified and addressed capability gaps in maritime homeland defense, and (3) made progress with interagency partners, such as the U.S. Coast Guard, in addressing information sharing challenges related to maritime domain awareness. To conduct this work, GAO examined national and DOD guidance and interviewed officials from DOD, Joint Staff, combatant commands, the military services, and others."
