Maritime Security
Immediately after the terrorist attacks on 9/11, the Coast Guard expanded its port security activities. The Ports, Waterways and Coastal Security (PWCS) mission entails the protection of the U.S. Maritime Domain and the U.S. Marine Transportation System and those who live, work or recreate near them; the prevention and disruption of terrorist attacks, sabotage, espionage, or subversive acts; and response to and recovery from those that do occur.
The influx of illegal drugs is one of America's maritime-security problems. As the nation's leading maritime agency in protecting the U.S. public from the drug threat, the Coast Guard plays a key role in implementing the President's national drug-control strategy. Despite the vast complications in enforcement, the Coast Guard performs this new task with only modest additional funding. A tremendous number of assets are required to patrol the long coastlines of the United States and the even greater expanse of waters encompassing the maritime "transit zones" used by drug smugglers. This six-million-square-mile area, roughly the size of the continental United States itself, includes the Caribbean, the Gulf of Mexico, and the Eastern Pacific.The protection of U.S. living marine resources--primarily through the detection and deterrence of illegal fishing activity--is another of the Coast Guard's historic mission areas of responsibility that continues to expand. Beginning with the protection of the Bering Sea fur seal and sea otter herds and continuing through the vast expansion following World War II in the size and efficiency of global fishing fleets, Coast Guard responsibilities in this mission area now include enforcement of laws and treaties in the 3.36-million-square-mile U.S. Exclusive Economic Zone (EEZ), the largest in the world.
The flood of undocumented migrants in boats onto America’s shores is both a threat to human life and a violation of U.S. and international laws. Coast Guard migrant-interdiction operations are as much humanitarian efforts as they are law-enforcement missions. In fact, the majority of migrant interdiction cases handled by the Coast Guard actually begin as search-and-rescue missions, usually on the high seas rather than in U.S. coastal waters. The Coast Guard is the lead agency for the enforcement of U.S. immigration laws at sea, stressing sensitivity in dealing with undocumented migrants in all realms: mass migration, asylum/refugee requests, smuggling and repatriation. In its effort to increase U.S. security against undocumented migrations, the Coast Guard constantly monitors maritime transit zones, interdicting undocumented migrants, rescuing people from sinking or unsafe vessels, providing humanitarian assistance, and training nations to discourage undocumented migration into the United States.
