OVERVIEW

Naval Air Station Key West sits at the southern tip of the Florida Keys and is the U.S. Navy's premier Atlantic Fleet adversary air training installation, supporting carrier air wings, joint partners, and select international forces in dissimilar air combat training over the open warning areas of the Florida Straits and the eastern Gulf of Mexico. The base spans about 5,769 acres across several Florida Keys sites, including the operational airfield at Boca Chica Field on Boca Chica Key, the Truman Annex on the southern end of Key West, and Sigsbee Park and Trumbo Point in the city of Key West.

The host installation supports Strike Fighter Squadron Composite 111 (VFC-111) "Sundowners," which flies F-5N Tiger II adversary aircraft to provide realistic aggressor opposition for fleet strike-fighter training. NAS Key West also supports the Naval Air Warfare Center Key West Detachment, conducting test and evaluation work in the unrestricted offshore airspace, and hosts Joint Interagency Task Force South (JIATF-S) at the Truman Annex — a multi-agency, multi-national counter-narcotics command coordinating detection and monitoring of illicit trafficking across the Caribbean and Eastern Pacific. The base's location 90 miles from Cuba and astride the Florida Straits makes it a critical forward node for naval, joint, and interagency operations in the southern approaches to the United States.

HISTORY

The U.S. Navy's presence in Key West dates to 1823, when Commodore David Porter's West India Squadron established a base in the new port to combat Caribbean piracy and protect U.S. commercial shipping in the Florida Straits and the Gulf of Mexico. Through the 19th century, Key West served as a recurring Navy coaling station, repair facility, and hurricane refuge for ships operating in the Caribbean. The harbor's deep water and sheltered anchorage made it a natural choice for Navy operations even during periods of extreme isolation from the U.S. mainland.

Naval Air Station Key West was formally established in 1917 at Trumbo Point in the city of Key West to support coastal patrol seaplanes flying anti-submarine and convoy escort missions during World War I. After the war, the air station was placed in caretaker status, but the Navy retained its land and facilities. As the prospect of another major war loomed in the late 1930s, the Navy reactivated and expanded the air station, building Boca Chica Field on Boca Chica Key as a conventional runway facility to complement the seaplane operations at Trumbo Point. By 1943, NAS Key West was a major training and operational base supporting anti-submarine patrol, fleet pilot training, and convoy support across the Caribbean and Gulf of Mexico.

The post-WWII era and onset of the Cold War cemented Key West's role as a forward U.S. naval and military base. In 1947, President Harry Truman established the Little White House on the base's Truman Annex, using it as his Florida winter residence — a connection that gave the site its enduring name. The Cuban Revolution in 1959 and the Cuban Missile Crisis of 1962 dramatically elevated NAS Key West's strategic importance: the base hosted Air Force F-100 and F-104 fighters, Navy F-8 Crusaders, and intelligence-collection aircraft during the crisis, and remained a major forward base for surveillance of Cuba throughout the Cold War.

Through the late Cold War and post-Cold War decades, the base evolved into its modern role. The Navy consolidated adversary training at Key West in the 1980s and 1990s, taking advantage of the unrestricted offshore airspace, near-perfect flying weather, and proximity to the carrier air wing East Coast workup cycle. Joint Interagency Task Force South relocated to Key West in 1999 from Howard Air Force Base in Panama, after the U.S. departure from the Panama Canal Zone. Today, NAS Key West continues to serve as the Navy's premier East Coast adversary air training base, the operational base of JIATF-S, and a key forward presence anchoring the southern approaches to the United States.
