Search and rescue
The mission the public knows the service by. Coast Guard crews saved 11,173 lives in a recent year, operating from small-boat stations, cutters and air stations around the clock.
Personnel figures are FY2024 actuals (GAO-25-107224); budget is FY2026 enacted; cutter and boat counts are as listed by the Coast Guard in October 2026.
The United States Coast Guard is one of the six armed forces of the United States and the only one that is a law enforcement agency at the same time. It was established on August 4, 1790, when Congress — at Treasury Secretary Alexander Hamilton’s urging — authorized ten cutters to enforce customs law. That makes it older than the Navy in continuous existence, because between 1790 and 1798 the Revenue Cutter Service was the only armed force the United States had afloat.
The Coast Guard is unique in where it sits. Title 14 of the U.S. Code makes it a service in the Department of Homeland Security, except when operating as a service in the Navy — a transfer that occurs upon a declaration of war if Congress directs it, or whenever the President directs. It has actually happened twice, in 1917 and again from 1941 to 1946.
Its other distinction is legal rather than organizational. The Posse Comitatus Act restricts the Army and Air Force — and, by Defense Department policy, the Navy and Marine Corps — from domestic law enforcement. It does not reach the Coast Guard. Title 14 gives Coast Guard members authority to make inquiries, examinations, inspections, searches, seizures and arrests on the high seas and on waters under U.S. jurisdiction. It is the only armed service that can lawfully board a vessel, arrest its crew and seize its cargo as a matter of routine peacetime business.
That combination produces an unusually broad mission set. Congress assigns eleven statutory missions ranging from search and rescue and aids to navigation through drug and migrant interdiction to defense readiness — a service of roughly 39,000 active-duty members doing work that in most countries is split among a navy, a coastguard, a customs service, a fisheries agency and a lighthouse authority.
Federal law assigns the Coast Guard eleven statutory missions, divided between homeland security and non-homeland security functions. Together they define the broadest mandate of any American armed service.
The mission the public knows the service by. Coast Guard crews saved 11,173 lives in a recent year, operating from small-boat stations, cutters and air stations around the clock.
Interdicting narcotics and irregular maritime migration far from American shores. A recent fiscal year saw roughly 510,000 pounds of cocaine seized — about three times the annual average.
Protecting American ports, the vessels in them and the marine transportation system that carries the overwhelming majority of U.S. trade by volume.
Maintaining the buoys, lights and channel markings that make American waterways navigable — a direct inheritance from the Lighthouse Service.
Inspecting commercial vessels, investigating casualties, and leading the federal response to oil and hazardous material spills in U.S. waters.
Polar and Great Lakes icebreaking, Arctic presence, and combat-ready forces that deploy with the Navy in wartime and support combatant commanders in peacetime.
The Coast Guard divides the country between two Areas and nine districts. In July 2025 the districts were renamed from numbers to geographic names under Force Design 2028 — the first change of its kind in over a century.
Portsmouth, Virginia — operations from the Rocky Mountains east, plus the Atlantic, Caribbean and Gulf.
Alameda, California — operations from the Rockies west, plus the Pacific and Arctic.
Training, doctrine and force readiness across the service.
Northeast, East, Southeast, Heartland, Great Lakes, Southwest, Northwest, Oceania and Arctic.
The operational building block — each combines a captain of the port, small-boat stations, cutters and response assets for a stretch of coast.
Roughly 20,000 uniformed civilian volunteers supporting every non-law-enforcement, non-military mission.
The cutter fleet is organized by endurance and size, from ocean-going national security cutters to river tenders.
| National Security Cutter | 418 ft · long-range major cutter | Captain |
|---|---|---|
| Offshore Patrol Cutter | 360 ft · replacing medium-endurance cutters | Commander |
| Medium Endurance Cutter | 210–270 ft · the fleet’s workhorse | Commander |
| Fast Response Cutter | 154 ft · patrol and interdiction | Lieutenant |
| Polar / Arctic Security Cutter | Icebreaking and polar presence | Captain |
| Buoy tenders and river tenders | Aids to navigation and waterways | Lieutenant or chief warrant officer |
The Coast Guard is an amalgamation. Five separate federal agencies were folded into it over 150 years, and every one of them left a mission behind.
Alexander Hamilton needed customs revenue, and smugglers were taking it. On August 4, 1790 Congress authorized ten cutters to enforce tariff law — the Revenue Cutter Service, and the date the Coast Guard observes as its birthday. Because the Continental Navy had been sold off in 1785 and the Department of the Navy was not created until 1798, those cutters were for eight years the only armed force the United States had at sea.
The lifesaving mission arrived separately. Federal funds first went to lifeboat stations on the New Jersey coast in 1848, and a Life-Saving Service was organized within the Revenue Marine Division in 1871, put under a general superintendent by the act of 1878. On January 28, 1915 Congress merged the Revenue Cutter Service and the Life-Saving Service to create the United States Coast Guard.
Three more agencies followed. The Lighthouse Service was abolished and its functions transferred to the Coast Guard in 1939, bringing the aids-to-navigation mission and thousands of lighthouse keepers. The Bureau of Marine Inspection and Navigation transferred in 1942 and permanently in 1946, bringing commercial vessel inspection and merchant mariner licensing. Along the way the service went to war twice under Navy command, in 1917 and again from November 1941 until January 1946.
Its departmental home has moved three times. The Coast Guard sat under the Treasury Department until April 1, 1967, when the Department of Transportation Act moved it to DOT. On March 1, 2003 it moved again, to the newly created Department of Homeland Security, where it remains. Force Design 2028, launched in 2025, is the largest reorganization since that move.

The largest funding increase in service history is paired with a restructuring, geographic district names, and a goal of growing the workforce by more than 15,000.
The Coast Guard is executing Force Design 2028, a restructuring paired with roughly $24.6 billion in additional funding provided in 2025 — the largest single infusion in the service’s history — aimed at growing the workforce by more than 15,000 and recapitalizing a fleet whose average age is among the oldest in the U.S. military.

USCGC Storis, commissioned in August 2025, is the first polar icebreaker the service has acquired in more than twenty-five years.
Coast Guard rank titles mirror the Navy almost exactly — Seamen and Petty Officers below, Ensigns to Admirals above. The differences are at the margins: the Coast Guard uses only three warrant officer grades, has no five-star grade, and by long tradition the Commandant is its only four-star billet alongside the Vice Commandant.
The W-1 and CWO5 grades are no longer used in the Coast Guard — a divergence from both the Navy, which uses CWO2 through CWO5, and the Army and Marine Corps, which use W-1 through W-5. Devices shown are schematic diagrams of each pay-grade tier, not reproductions of official insignia artwork.
Coast Guard identity is built around two symbols that almost every American recognizes without being able to name — the racing stripe and the shield.
Coast Guard Blue, Coast Guard Red and white. The red is the more visible of the two, because it dominates the racing stripe on every cutter, boat and aircraft in the service.
Designed by the Raymond Loewy design office under a 1964 contract, after President Kennedy suggested the service needed a stronger visual identity. A wide red bar above a narrow blue bar, canted at 64 degrees, with the Coast Guard shield. Service-wide implementation was ordered on April 6, 1967, and the design has since been copied by coast guards worldwide.
Established in 1799 by Treasury Secretary Oliver Wolcott — sixteen vertical red and white stripes, one for each state in the Union at the time. It is flown by cutters to signal their law enforcement authority, and it predates the modern service by more than a century.
Always Ready. The motto is also the title of the service march, with lyrics written in 1922 and music in 1927 by Captain Francis Saltus Van Boskerck, adopted in 1928.
Honor, Respect and Devotion to Duty — three values rather than the four or seven other services use, and notably including respect as a stated core commitment.
The blue eagle of the U.S. coat of arms on a white field, with UNITED STATES COAST GUARD above and SEMPER PARATUS and 1790 below — the founding year carried on the seal itself.
August 4, 1790, when Congress authorized ten revenue cutters at Alexander Hamilton’s urging. The modern service dates from January 28, 1915, when the Revenue Cutter Service merged with the Life-Saving Service, but the 1790 date is the official birthday.
Yes. Title 14 of the U.S. Code makes the Coast Guard an armed force at all times — one of the six branches of the U.S. Armed Forces. It differs from the others in that it operates under the Department of Homeland Security rather than the Department of Defense, and it transfers to the Navy in wartime when the President or Congress directs.
More than 39,000 on active duty, about 6,300 reservists and roughly 9,650 civilian employees, plus approximately 20,000 uniformed Auxiliary volunteers — a total workforce of more than 76,000. Force Design 2028 aims to add more than 15,000 members by the end of fiscal year 2028.
Search and rescue; aids to navigation; marine safety; living marine resources; marine environmental protection; ice operations; ports, waterways and coastal security; drug interdiction; migrant interdiction; defense readiness; and other law enforcement. The first six are non-homeland security missions and the last five are homeland security missions.
The Posse Comitatus Act restricts the Army and Air Force from domestic law enforcement, and Defense Department policy extends that to the Navy and Marine Corps. It does not apply to the Coast Guard. Title 14 explicitly authorizes Coast Guard members to make inquiries, searches, seizures and arrests on the high seas and on waters under U.S. jurisdiction.
Semper Paratus — Latin for Always Ready. It is also the title of the service march, written by Captain Francis Saltus Van Boskerck and adopted in 1928.
Enlisted ranks run Seaman Recruit, Seaman Apprentice, Seaman, then Petty Officer Third, Second and First Class, then Chief, Senior Chief and Master Chief Petty Officer. Officers run Ensign, Lieutenant Junior Grade, Lieutenant, Lieutenant Commander, Commander, Captain, then Rear Admiral lower half through Admiral. Warrant officers use only CWO2, CWO3 and CWO4.
It is the service’s visual identity mark, designed by the Raymond Loewy office in 1964 and adopted service-wide in 1967: a wide Coast Guard Red bar above a narrow Coast Guard Blue bar, canted at 64 degrees, with the service shield. It has since been adopted in similar form by coast guards around the world.
Title 14 provides that upon a declaration of war, if Congress so directs, or whenever the President directs, the Coast Guard operates as a service in the Navy until the President transfers it back. It has happened twice — in the First World War from 1917 to 1919, and in the Second World War from November 1941 to January 1946.
Older than any other U.S. sea service. The Coast Guard operates 259 cutters and more than 1,600 boats, and its recapitalization programs — the Polar and Arctic Security Cutters, the Offshore Patrol Cutter, the Fast Response Cutter and the Waterways Commerce Cutter — are replacing hulls that in some cases have been in service for more than fifty years.
