By signing National Security Presidential Directive-41/Homeland Security Presidential Directive-13 (NSPD-41/HSPD-13) (Maritime Security Policy, December 21, 2004) the President underscored the importance of securing the Maritime Domain and established a Maritime Security Policy Coordinating Committee to oversee the development of a National Strategy for Maritime Security (NSMS) and the following eight supporting implementation plans: Maritime Domain Awareness, Global Maritime Intelligence Integration Plan, Maritime Operational Threat Response Plan, International Outreach and Coordination Strategy, Maritime Infrastructure Recovery Plan, Maritime Transportation System Security Plan, Maritime Commerce Security Plan and Domestic Outreach Plan. Although these plans address different aspects of maritime security, they link and reinforce each other.
Since 9/11, the WGD has become a primary player in the examination of Maritime Homeland Security (HS), Maritime Homeland Defense (HD) and Defense Support of Civil Authorities (DSCA) issues. The WGD has provided direct support to OPNAV, DOD and the Fleet through efforts that concentrated on support to NSMS, Maritime Operational Center (MOC), as the defined C2 structure for the U.S. Navy and the development MDA concepts. Through direct support to the U.S. Navy and the U.S. Coast Guard, WGD developed the annual Maritime Homeland Security/Maritime Homeland Defense (MHS/MHD) War Game to improve USCG/USN relationships, Command and Control (C2), transfer of forces processes, MHS/MHD CONOPS, plans, orders, and agreements, as well as coordination issues associated with Canadian and Mexican forces. An outcome of this game has been the development of several additional annual games, such as, the Maritime Operational Threat Response (MOTR) games, MOTR Forces games, PACFLT Maritime Security games, Maritime Domain Awareness (MDA) games and a variety of domestic and international outreach events. These events have directly affected those organizations that respond to maritime security issues at both the strategic and operational decision making levels.
The WGD has also provided a number of events for DHS, States, Tribes and Municipalities with a range of Homeland Security issues and concentrated on DOD support of civil authorities (DSCA). Each of these games highlighted the need to improve organizational preparedness for terrorist attacks as well as their C2 capabilities. They also stressed the integration/socialization of Interagency Memorandums of Agreement (MOAs) and Operational Orders (OPORDS). These games also provided the NWC exposure to civil support and interagency coordination from the Federal, State, Tribal and Local perspectives.
