Naval Air Station Key West, located at Boca Chica Field, is a United States Navy installation situated on Boca Chica Key in Monroe County, Florida. It serves as a premier tactical air warfare training facility, taking advantage of the extensive restricted airspace and warm-weather flying conditions available in the Florida Keys region. The installation hosts various Navy and Marine Corps aviation squadrons, as well as tenant commands and visiting units conducting combat training exercises. Its location near Cuba and proximity to the Gulf of Mexico and Atlantic Ocean make it strategically significant for military operations and training. While it carries IATA code NQX, the facility is a military airfield and does not serve scheduled commercial passenger flights. Civilian access is restricted, and the airfield primarily supports U.S. military aviation activities.
