United States Coast Guard

The **United States Coast Guard** (**USCG**) is the maritime security, search and rescue, and law enforcement service branch of the United States Armed Forces and one of the country's eight uniformed services. The service is a maritime, military, multi-mission service unique among the United States military branches for having a maritime law enforcement mission with jurisdiction in both domestic and international waters and a federal regulatory agency mission as part of its duties. It is the largest and most powerful coast guard in the world, rivaling the capabilities and size of most navies.

The U.S. Coast Guard is a humanitarian and security service. It protects the United States' borders and economic and security interests abroad; and defends its sovereignty by safeguarding sea lines of communication and commerce across U.S. territorial waters and its Exclusive Economic Zone. Due to ever-expanding risk imposed by transnational threats through the maritime and cyber domains, the U.S. Coast Guard is at any given time deployed to and operating on all seven continents and in cyberspace to enforce its mission. Like its United States Navy sibling, the U.S. Coast Guard maintains a global presence with permanently-assigned personnel throughout the world and forces routinely deploying to both littoral and blue-water regions. The U.S. Coast Guard's adaptive, multi-mission "white hull" fleet is leveraged as a force of both diplomatic soft power and humanitarian and security assistance over the more overtly confrontational nature of "gray hulled" warships. As a humanitarian service, it saves tens of thousands of lives a year at sea and in U.S. waters, and provides emergency response and disaster management for a wide range of man-made and natural catastrophic incidents in the U.S. and throughout the world.

The U.S. Coast Guard operates under the U.S. Department of Homeland Security during peacetime. During times of war, it can be transferred in whole or in part to the U.S. Department of the Navy under the Department of Defense by order of the U.S. President or by act of Congress. Prior to its transfer to Homeland Security, it operated under the Department of Transportation from 1967 to 2003 and the Department of the Treasury from its inception until 1967. A congressional authority transfer to the Navy has only happened once: in 1917, during World War I. By the time the U.S. entered World War II in December 1941, the U.S. Coast Guard had already been transferred to the Navy by President Franklin Roosevelt.

Created by Congress as the Revenue-Marine on 4 August 1790 at the request of Alexander Hamilton, it is the oldest continuously operating naval service of the United States. As Secretary of the Treasury, Hamilton headed the Revenue-Marine, whose original purpose was collecting customs duties at U.S. seaports. By the 1860s, the service was known as the U.S. Revenue Cutter Service and the term Revenue-Marine gradually fell into disuse.

The modern U.S. Coast Guard was formed by a merger of the U.S. Revenue Cutter Service and the U.S. Life-Saving Service on 28 January 1915, under the Department of the Treasury. In 1939, the U.S. Lighthouse Service was also merged into the U.S. Coast Guard. As one of the country's six armed services, the U.S. Coast Guard has deployed to support and fight every major U.S. war since 1790, from the Quasi-War with France to the Global War on Terrorism.

As of December 2021, the U.S. Coast Guard's authorized force strength is 44,500 active duty personnel and 7,000 reservists. The service's force strength also includes 8,577 full-time civilian federal employees and 31,000 uniformed volunteers of the U.S. Coast Guard Auxiliary. The service maintains an extensive fleet of roughly 250 coastal and ocean-going cutters, patrol ships, buoy tenders, tugs, and icebreakers; as well as nearly 2,000 small boats and specialized craft. It also maintains an aviation division consisting of more than 200 helicopters and fixed-wing aircraft. While the U.S. Coast Guard is the second smallest of the U.S. military service branches in terms of membership, the service by itself is the world's 12th largest naval force.

## Mission

### Role

The Coast Guard carries out three basic roles, which are further subdivided into eleven statutory missions. The three roles are:

* Maritime safety
* Maritime security
* Maritime stewardship

With a decentralized organization and much responsibility placed on even the most junior personnel, the Coast Guard is frequently lauded for its quick responsiveness and adaptability in a broad range of emergencies. In a 2005 article in *Time* magazine following Hurricane Katrina, the author wrote, "the Coast Guard's most valuable contribution to [a military effort when catastrophe hits] may be as a model of flexibility, and most of all, spirit." Wil Milam, a rescue swimmer from Alaska told the magazine, "In the Navy, it was all about the mission. Practicing for war, training for war. In the Coast Guard, it was, take care of our people and the mission will take care of itself."

### Missions

The eleven statutory missions as defined by law are divided into homeland security missions and non-homeland security missions:

#### Non-homeland security missions

* Ice operations, including the International Ice Patrol
* Living marine resources (fisheries law enforcement)
* Marine environmental protection
* Marine safety
* Aids to navigation
* Search and rescue

#### Homeland security missions

* Defense readiness
* Maritime law enforcement
* Migrant interdiction
* Ports, waterways and coastal security (PWCS)
* Drug interdiction

### Search and rescue

The U.S. Coast Guard Search and Rescue (CG-SAR) is one of the Coast Guard's best-known operations. The *National Search and Rescue Plan*designates the Coast Guard as the federal agency responsible for maritime SAR operations, and the United States Air Force as the federal agency responsible for inland SAR. Both agencies maintain rescue coordination centers to coordinate this effort, and have responsibility for both military and civilian search and rescue. The two services jointly provide instructor staff for the National Search and Rescue School that trains SAR mission planners and coordinators. Previously located on Governors Island, New York, the school is now located at Coast Guard Training Center Yorktown at Yorktown, Virginia.

### National Response Center

Operated by the Coast Guard, the National Response Center (NRC) is the sole U.S. Government point of contact for reporting all oil, chemical, radiological, biological, and etiological spills and discharges into the environment, anywhere in the United States and its territories. In addition to gathering and distributing spill/incident information for Federal On Scene Coordinators and serving as the communications and operations center for the National Response Team, the NRC maintains agreements with a variety of federal entities to make additional notifications regarding incidents meeting established trigger criteria. The NRC also takes Maritime Suspicious Activity and Security Breach Reports. Details on the NRC organization and specific responsibilities can be found in the National Oil and Hazardous Substances Pollution Contingency Plan. The Marine Information for Safety and Law Enforcement (MISLE) database system is managed and used by the Coast Guard for tracking pollution and safety incidents in the nation's ports.

### National Maritime Center

The National Maritime Center (NMC) is the merchant mariner credentialing authority for the USCG under the auspices of the Department of Homeland Security. To ensure a safe, secure, and environmentally sound marine transportation system, the mission of the NMC is to issue credentials to fully qualified mariners in the United States maritime jurisdiction.

The six uniformed services that make up the U.S. Armed Forces are defined in Title 10 of the U.S. Code:

> The term "armed forces" means the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard.
>
>

The Coast Guard is further defined by Title 14 of the United States Code:

> The Coast Guard as established January 28, 1915, shall be a military service and a branch of the armed forces of the United States at all times. The Coast Guard shall be a service in the Department of Homeland Security, except when operating as a service in the Navy.
>
>

Coast Guard organization and operation is as set forth in Title 33 of the Code of Federal Regulations.

On 25 November 2002, the Homeland Security Act was signed into law by U.S. President George W. Bush, designating the Coast Guard to be placed under the U.S. Department of Homeland Security. The transfer of administrative control from the U.S. Department of Transportation to the U.S. Department of Homeland Security was completed the following year, on 1 March 2003.

The U.S. Coast Guard reports directly to the civilian Secretary of Homeland Security. However, under 14 U.S.C. § 3 as amended by section 211 of the Coast Guard and Maritime Transportation Act of 2006, upon the declaration of war and when Congress so directs in the declaration, or when the President directs, the Coast Guard operates under the Department of Defense as a service in the Department of the Navy.

As members of the military, Coast Guardsmen on active and reserve service are subject to the Uniform Code of Military Justice and receive the same pay and allowances as members of the same pay grades in the other uniformed services.

The service has participated in every major U.S. conflict from 1790 through today, including landing troops on D-Day and on the Pacific Islands in World War II, in extensive patrols and shore bombardment during the Vietnam War, and multiple roles in Operation Iraqi Freedom. Maritime interception operations, coastal security, transportation security, and law enforcement detachments have been its major roles in recent conflicts in Iraq.

On 17 October 2007, the Coast Guard joined with the U.S. Navy and U.S. Marine Corps to adopt a new maritime strategy called *A Cooperative Strategy for 21st Century Seapower* that raised the notion of prevention of war to the same philosophical level as the conduct of war. This new strategy charted a course for the Navy, Coast Guard and Marine Corps to work collectively with each other and international partners to prevent regional crises, man-made or natural, from occurring, or reacting quickly should one occur to avoid negative impacts to the United States. During the launch of the new U.S. maritime strategy at the International Seapower Symposium at the U.S. Naval War College in 2007, Coast Guard Commandant Admiral Thad Allen said the new maritime strategy reinforced the time-honored missions the service has carried out in the United States since 1790. "It reinforces the Coast Guard maritime strategy of safety, security and stewardship, and it reflects not only the global reach of our maritime services but the need to integrate and synchronize and act with our coalition and international partners to not only win wars ... but to prevent wars," Allen said.

### Authority as a law enforcement agency

Title 14 USC, section 2 authorizes the Coast Guard to enforce U.S. federal laws. This authority is further defined in 14 U.S.C. § 522, which gives law enforcement powers to all Coast Guard commissioned officers, warrant officers, and petty officers. Unlike the other branches of the United States Armed Forces, which are prevented from acting in a law enforcement capacity by 18 U.S.C. § 1385, the Posse Comitatus Act, and Department of Defense policy, the Coast Guard is exempt from and not subject to the restrictions of the Posse Comitatus Act.

Further law enforcement authority is given by 14 U.S.C. § 703 and 19 U.S.C. § 1401, which empower U.S. Coast Guard active and reserve commissioned officers, warrant officers, and petty officers as federal customs officers. This places them under 19 U.S.C. § 1589a, which grants customs officers general federal law enforcement authority, including the authority to:

> (1) carry a firearm;
>
>
> (2) execute and serve any order, warrant, subpoena, summons, or other process issued under the authority of the United States;
>
>
> (3) make an arrest without a warrant for any offense against the United States committed in the officer's presence or for a felony, cognizable under the laws of the United States committed outside the officer's presence if the officer has reasonable grounds to believe that the person to be arrested has committed or is committing a felony; and
>
>
> (4) perform any other law enforcement duty that the Secretary of Homeland Security may designate.

The U.S. Government Accountability Office Report to the House of Representatives, Committee on the Judiciary on its 2006 Survey of Federal Civilian Law Enforcement Functions and Authorities, identified the Coast Guard as one of 104 federal components that employed law enforcement officers. The report also included a summary table of the authorities of the Coast Guard's 192 special agents and 3,780 maritime law enforcement boarding officers.

Coast Guardsmen have the legal authority to carry their service-issued firearms on and off base. This is rarely done in practice, however; at many Coast Guard stations, commanders prefer to have all service-issued weapons in armories when not in use. Still, one court has held in the case of *People v. Booth* that Coast Guard boarding officers are qualified law enforcement officers authorized to carry personal firearms off-duty for self-defense.
