THE LARGEST COAST GUARD BASES: RANKED BY LAND AREA & POPULATION
Defining the “largest” military base means considering both land area and population for true scale and community. Here, we examine five of the largest U.S. Coast Guard bases using verified data on acreage and personnel. Each section outlines why the base matters for the mission, families, and community.
1. Base Kodiak (Kodiak Island, Alaska)
Land Area: ~23,000 acres.
Personnel/population: Rough estimates indicate ~1,100 military personnel and ~1,600 dependents in the Kodiak community.
Why it leads the list:
- By land area, Base Kodiak is widely cited as the largest USCG base.
- Mission footprint is massive: supporting search and rescue, cutters, aviators across roughly 4 million sq mi of Alaskan waters.
- For families: remote island life, dramatic weather and landscapes, and a unique community dynamic.
Interesting fact: The base supports both cutters and aircraft — the only USCG base to do so in one command structure.
2. Base Elizabeth City (Elizabeth City, North Carolina)
Land Area: ~822 acres.
Personnel/population: ~2,000 Coast Guard personnel & civilian employees, plus hundreds of dependents.
Why it ranks high:
- It’s the largest aviation/mission-support hub on the East Coast for the USCG.
- Strong community infrastructure: a base anchoring a mid-sized city and economy.
Interesting fact: Base Elizabeth City is the largest employer in northeastern North Carolina and contributes a significant economic impact to the region.
3. Base Alameda (Coast Guard Island, San Francisco Bay, California)
Land Area: ~67 acres (artificial island footprint).
Personnel/population: ~1,200-plus active duty, civilians, and contractors.
Why it still makes the list:
- Base Alameda is a key West Coast mission hub: home to a major command (Pacific Area), high-visibility cutters.
- An urban setting offers many amenities and employment options for spouses, though at a higher cost of living.
Interesting fact: The island is artificial, formed by dredging in 1913, and now hosts four national security cutters.
4. Base Miami Beach (Miami Beach, Florida)
Land Area: Not widely published for the overall complex; however, Causeway Island accounts for about 11.5 acres.
Personnel/population: The official allocation document lists ~240-288 personnel for Base Miami Beach in FY 2021.
Why it’s notable:
- Base Miami Beach is a strategic location covering South Florida, the Caribbean, and Atlantic maritime operations.
- Lifestyle appeal: tropical climate, coastal living, access to major metropolitan areas.
Interesting fact: Although smaller in acreage and personnel than others, its mission scope in the 7th District and Caribbean is substantial.
5. PATFORSWA — Forward-Deployed Overseas (Manama, Bahrain)
Land Area: Not applicable in the base-land sense; however, this is the USCG’s largest unit outside the U.S.
Personnel/population: The main parent installation, Naval Support Activity Bahrain, hosts around 7,200 military and civilian personnel, many of whom are USCG.
Why we included it:
- While not a “base” in the traditional sense of large land acreage, its scale of personnel and global mission make it significant to the USCG’s global footprint.
- For families or service members considering assignments outside the continental U.S., both the scope and scale of this unit are important.
Interesting fact: Six fast-response cutters are deployed here, making PATFORSWA the Coast Guard’s largest unit overseas.
Key Takeaways for Families
- Mission matters: A smaller land base may offer high-tempo, rich assignments (e.g., Miami).
- Community infrastructure: Family-friendly services, schooling, and housing may vary dramatically even within the “largest” bases.
- Lifestyle vs. mission trade-off: Urban vs. remote; cost of living; housing availability; operational tempo.
- Don’t overlook OCONUS/overseas: The USCG isn’t just domestic; scale and mission globally may present assignment opportunities and lifestyle differences.
Largest U.S. Coast Guard Bases Ranked by Land Area & Population
7 Surprising Facts About the Largest Coast Guard Bases
1. The Coast Guard’s “mega-base” is in Alaska.
Base Kodiak spans roughly 23,000 acres—larger than many Army and Navy posts—and oversees operations across almost 4 million square miles of ocean.
2. Elizabeth City is the Coast Guard’s aviation powerhouse.
With ~2,000 personnel and multiple aviation commands, it’s the service’s largest aviation complex and a critical East Coast search-and-rescue hub.
3. Alameda sits on a man-made island.
Coast Guard Island was created by dredging in 1913 and now hosts major cutters, the Pacific Area command, and more than a thousand personnel.
4. Miami isn’t large—just mission-heavy.
Despite only ~11.5 acres of base footprint on Causeway Island, the operational reach across South Florida and the Caribbean is enormous.
5. The Coast Guard has a major overseas presence.
PATFORSWA in Bahrain is the Coast Guard’s largest unit outside the United States, forward-deploying fast-response cutters to protect key waterways.
6. “Largest” doesn’t always mean most populated.
Some of the most spacious bases (like Kodiak) have smaller populations due to remote geography and mission specialization.
7. Coast Guard bases shape local economies.
Elizabeth City alone is one of northeastern North Carolina’s biggest employers, influencing housing, schools, and regional growth.
