Naval Amphibious Base Coronado is a United States Navy installation on the Silver Strand in Coronado, California near San Diego Bay that supports maritime, amphibious, and special operations forces. The installation provides berthing, training, logistics, and staging facilities for units associated with United States Special Operations Command, United States Pacific Fleet, Naval Special Warfare Command, and regional assets such as Commander, Naval Surface Forces Pacific and Navy Expeditionary Combat Command. Established during World War I and expanded through World War II, the base has been integral to operations linked to Battle of Guadalcanal, Korean War, Vietnam War, and post-9/11 operations in Operation Enduring Freedom and Operation Iraqi Freedom.

History

The site was first developed as part of early 20th-century expansion tied to Panama–California Exposition era growth and strategic needs identified by General John J. Pershing and planners influenced by Alfred Thayer Mahan. Initial construction in 1917 created facilities used by United States Army and United States Navy units during World War I and later during World War II for staging amphibious training linked to operations such as Operation Torch and Operation Overlord-adjacent doctrine development. Postwar reorganizations under Department of Defense (1947–present) and directives from Secretary of the Navy offices transformed the base into a center for Naval Amphibious doctrine, supporting units involved in Inchon landing-era lessons, Hainan Island Incident-era contingency planning, and the emergence of SEAL Team One and SEAL Team Two doctrine. Cold War expansions were influenced by strategic guidance from National Security Council documents and joint exercises with United States Marine Corps elements stationed at Camp Pendleton and allied forces such as Royal Navy and Australian Defence Force contingents.

The base encompasses piers, berthing, ranges, and training beaches adjacent to Silver Strand State Beach and infrastructure coordinating with San Diego International Airport airspace and Naval Air Station North Island aviation assets. Key fixed facilities include small craft piers used by Mark V Special Operations Craft, logistics hubs interoperable with Military Sealift Command vessels, explosive ordnance disposal ranges supporting EOD Group elements, dive lockers and hyperbaric chambers used by Navy Experimental Diving Unit and Underwater Demolition Teams predecessors, and simulation centers connected to Naval Strike and Air Warfare Center curricula. Utilities and environmental remediation projects have involved partnerships with California Coastal Commission, U.S. Fish and Wildlife Service, and Environmental Protection Agency programs to manage wetlands, dunes, and infrastructure upgrades funded through military construction authorities from Congress and oversight by Department of the Navy engineering commands.

Tenant commands include elements of Naval Special Warfare Command, SEAL Team One, SEAL Team Three, and training detachments for Special Warfare Combatant-craft Crewmen and Naval Special Warfare Development Group-affiliated support, alongside Navy Information Warfare Community units and logistics elements from Commander, Navy Region Southwest. The base also hosts shore support for Explosive Ordnance Disposal Group units, Naval Mobile Construction Battalion contingents during exercises, and liaison detachments coordinating with United States Southern Command and United States Indo-Pacific Command task forces. Cooperative presences include Civil Air Patrol units, Federal Emergency Management Agency coordination cells for disaster response, and interoperability links with United States Border Patrol and California National Guard during homeland missions.

Training on the base ranges from amphibious assault rehearsals with Maritime Prepositioning Force elements to maritime interdiction and counterterrorism drills with Joint Special Operations Command participation and integration with Carrier Strike Group tasking cycles. Amphibious assault courses draw on doctrine codified with input from Marine Corps Warfighting Laboratory and exercises such as RIMPAC and Talisman Sabre where allied units from Japan Ground Self-Defense Force, Royal Australian Navy, and Royal Netherlands Navy have participated. Diving, parachute, small-unit tactics, and close-quarters battle training include ranges and simulators developed in coordination with Naval Special Warfare Center, Airborne Command, and civilian contractors historically tied to Lockheed Martin and Sierra Nevada Corporation for training systems. Logistics and staging support operations including pre-deployment inspections aligned with Defense Logistics Agency standards and joint readiness reviews under United States Transportation Command oversight.

Environmental stewardship involves habitat protection agreements with California Department of Fish and Wildlife and conservation measures to protect species listed under the Endangered Species Act coordinated with U.S. Fish and Wildlife Service and local agencies such as City of Coronado. Community relations include coordination with Coronado Unified School District on outreach programs, partnership initiatives with San Diego State University for research, and public safety collaboration with San Diego County Sheriff's Department and Coronado Police Department. Noise, range safety, and public access issues are managed through public meetings hosted with California Coastal Commission and county supervisors from San Diego County Board of Supervisors, while land-use planning interfaces with State of California coastal management policies and federal compatibility reviews.

The base has experienced incidents and security events ranging from training accidents involving SEAL Team alumni and Explosive Ordnance Disposal accidents to high-profile security alerts prompted by regional crises such as tensions involving People's Republic of China naval activity in the South China Sea and terrorist threats in the post-9/11 period. Investigations have involved Naval Criminal Investigative Service, Federal Bureau of Investigation, and interagency coordination with Department of Homeland Security components. Notable responses have included force protection changes influenced by doctrine updates after incidents such as USS Cole bombing and policy shifts under secretaries from the Department of Defense (1947–present) leadership.
