Key West NAS is a United States naval aviation installation located on Boca Chica Key adjacent to Key West. The station provides airfield, training, and range support for naval, joint, and allied aviation units, and supports operations in the Caribbean Sea, Gulf of Mexico, and Atlantic Ocean. Originally established during World War I, the base has hosted a succession of squadrons and tenant commands and serves as a permanent hub for maritime patrol, strike, and training activities.
Established in 1917 during World War I as a seaplane base, the installation expanded significantly before and during World War II to support anti-submarine patrols against German U-boats in the Atlantic U-boat campaign (World War I). During the Cold War the site hosted Anti-submarine warfare training and surveillance missions tied to tensions with the Soviet Union and operations in the Cuban Missile Crisis. Post-Cold War reorganizations saw tenant units associated with Carrier Air Wing detachments, Maritime patrol, and Fleet Replacement Squadron activities. The base has supported contingency operations including Operation Urgent Fury and Operation Uphold Democracy, and has periodically hosted allied exercises with partners such as Royal Air Force, Canadian Armed Forces, and Brazilian Air Force.
The installation comprises runways, ramps, hangars, maintenance shops, and an integrated maritime training range complex. Key infrastructure elements include an east–west runway suitable for F/A-18 Hornet-class operations, ordnance handling facilities compliant with NATO standards for allied interoperability, and a sprawling overwater training area with instrumented target arrays and threat simulation systems. Support facilities host tenant commands such as Fleet Logistics Support Squadron detachments, medical clinics aligned with Naval Hospital protocols, and family housing areas proximate to the Key West Historic District and municipal utilities.
NAS Key West hosts a mix of active-duty Navy squadrons, reserve elements, and transient carrier air wing detachments. Tenant organizations have included patrol squadrons equipped for P-3 Orion and P-8A Poseidon missions, strike fighter detachments such as those flying F/A-18 Super Hornet, and rotary-wing units conducting search and rescue and logistics flights. The station supports commands involved with Naval Air Training Command syllabi, Naval Special Warfare support, and cooperative mission planning with United States Coast Guard units based in the Florida Keys. Joint-use agreements have allowed United States Marine Corps and United States Air Force units to operate from the field for integrated training.
Over its operational life, aircraft flown to and from the installation have included seaplanes of the Curtiss era, patrol aircraft such as the P-2 Neptune, the long-serving P-3 Orion, and modern platforms including the P-8 Poseidon. Fighter and attack types that have deployed include F/A-18 Hornet, F/A-18E/F Super Hornet, and earlier models such as the A-7 Corsair II. Rotary-wing assets have included the MH-60 Seahawk and CH-46 Sea Knight for logistics and SAR. Training and target systems on the ranges incorporate telemetry pods, aerial target drones like the BQM-34 Firebee, and surface-to-air threat emulators compatible with allied munitions.
NAS Key West functions as a principal site for carrier air wing detachment work-ups, live-fire gunnery, and air-to-surface bombing practice for naval and allied aviation. The overwater ranges support combined-arms exercises with United States Southern Command objectives and interoperability drills with partners from NATO and regional militaries. Specialized events have included air combat maneuvering exercises, anti-surface warfare drills, and maritime interdiction training aligned with task forces operating under U.S. Fourth Fleet. The station’s proximity to international airspace permits realistic training against complex threat scenarios.
Situated within the ecologically sensitive Florida Keys, the installation balances operational tempo with protections for habitats such as coral reefs, mangrove wetlands, and endangered species like the Florida Keys National Marine Sanctuary resources. Environmental compliance involves coordination with agencies including the United States Fish and Wildlife Service and state environmental regulators to mitigate noise, ordnance debris, and water quality impacts. The base engages with the local Monroe County, Florida community through outreach initiatives, emergency response coordination with the City of Key West Fire Department, and economic ties that influence regional tourism and labor markets.
Significant events include support operations during the Cuban Missile Crisis maritime posture, emergency responses to hurricanes including Irma, and notable aircraft mishaps during training sorties that prompted investigations by Naval Safety Center protocols. The station has hosted high-visibility visits from senior leaders of the Department of the Navy and international delegations during joint exercises. Periodic environmental and community controversies have arisen over range usage and noise, leading to negotiated adjustments in operating hours and mitigation programs with local stakeholders.
