Naval Air Station Key West Truman Annex

Naval Air Station Key West Truman Annex was a United States Navy facility located on the western end of Key West, Florida that served as a coastal fortification, naval base, and aviation support site across the 19th and 20th centuries. The site originated with Fort Zachary Taylor, played roles during the American Civil War and Spanish–American War, hosted aviation and maritime units through both World Wars and the Cold War, and later became part of historic preservation and public recreation efforts near Boca Chica Key and Dry Tortugas National Park. The annex's evolution connected it with national leaders, strategic commands, and regional transportation nodes such as Key West International Airport.

History

The property traces to the construction of Fort Zachary Taylor beginning in 1828 under the United States Army Corps of Engineers and was garrisoned during the Mexican–American War and the American Civil War. In the late 19th century the fortification responded to tensions with Spain during the Spanish–American War and later supported the Atlantic Fleet in the prelude to World War I. The United States Navy established a presence in the area in the early 20th century, especially as aviation emerged during and after World War I. During World War II the annex expanded with coastal defenses and aviation facilities supporting Fleet Air Wing operations and antisubmarine patrols in the Atlantic Ocean and Caribbean Sea. Cold War exigencies linked the annex to United States Southern Command and North American Aerospace Defense Command airspace interests, while Presidents Harry S. Truman and Dwight D. Eisenhower visited the region, influencing federal attention. In the late 20th and early 21st centuries, base realignment and closure reviews, including actions by the Base Realignment and Closure Commission (BRAC), and local civic initiatives led to the decommissioning of some annex functions and repurposing for historic preservation, municipal use, and tourism associated with Key West National Wildlife Refuge.

Facilities and infrastructure

The annex comprised masonry fortifications from Fort Zachary Taylor, barracks, piers, hangars, fuel storage, and administrative buildings typical of a mixed coastal and aviation installation. Runways and support facilities were coordinated with Key West Naval Air Station (Boca Chica Field), aircraft maintenance units, and seaplane ramps used by patrol squadrons that traced lineage to Patrol Squadron 6 and other Patrol and Reconnaissance Wing units. Communications infrastructure linked the annex to the Naval Telecommunications Command and coastal radar sites installed during the Cold War. Logistic support involved piers capable of servicing destroyers and smaller combatants from the United States Atlantic Fleet, and warehouses that stored ordnance and aviation fuel following standards promulgated by the Department of Defense.

Operations and units

Operationally, the annex hosted aviation, coastal defense, and support elements including squadrons assigned to Commander, U.S. Fleet Forces Command and units tasked with antisubmarine warfare during World War II and the Cold War. Training detachments affiliated with Naval Air Training Command and transient carrier air wings utilized the facilities for live-aboard and shore-based operations. Tenant commands have included elements of Naval Air Station Key West (Boca Chica), fleet logistics units, and search and rescue detachments that coordinated rescues with United States Coast Guard Sector Key West. The annex also supported visits by aircraft assigned to Carrier Air Wing Eight and naval vessels conducting fleet exercises with partners such as the Royal Navy, Canadian Armed Forces, and regional navies.

Role in aviation training and missions

The annex augmented maritime patrol and fighter pilot training in the region, serving as a staging and support area for low-altitude and overwater training missions common to Carrier Air Wings, Helicopter Sea Combat Squadron detachments, and maritime surveillance squadrons. Proximity to restricted ranges and the Gulf Stream allowed training for tactics that involved anti-surface warfare and antisubmarine operations, coordination practiced with Air Force and allied air components during joint exercises. The facility's airspace and ranges were instrumental for weapons delivery training, carrier landing practice coordinated with Naval Air Station Pensacola and United States Naval Test Pilot School outreach, and for seasonal deployments that prepared units for operations in the Gulf of Mexico and Caribbean littoral.

Environmental and geographic setting

Geographically located at the western terminus of Key West Island, the annex occupies a subtropical maritime environment characterized by coral reef ecosystems contiguous with the Florida Keys National Marine Sanctuary. Habitat types included mangrove fringe, beach and dune systems, and nearshore seagrass beds that support species protected under statutes such as the Endangered Species Act and national conservation programs administered by United States Fish and Wildlife Service. Environmental stewardship efforts on and around the annex addressed legacy contamination remediation under guidance from the Environmental Protection Agency and coordinated with state agencies including the Florida Department of Environmental Protection. Sea-level rise, storm surge from systems like Hurricane Irma (2017) and long-term climate trends have influenced planning for infrastructure resilience.

Historic preservation and public access

Deactivation and transfer actions enabled portions of the annex to enter historic preservation and public recreation use, integrating the fort complex with interpretive programs administered by Florida State Parks partners and local historical societies in Monroe County, Florida. Museums, walking tours, and adaptive reuse projects preserved masonry works of Third System coastal fortifications and Cold War-era structures, while public access connected cultural resources to tourism corridors centered on Duval Street and Mallory Square. Collaborative stewardship involves the National Park Service, state preservation offices, and civic organizations that curate exhibits on figures such as President Harry S. Truman and events including Cuban Missile Crisis context for Florida Keys defense history.
