Summerdale Naval Outlying Field (ICAO: KNFD) is a military auxiliary airfield located near Summerdale, Alabama, in Baldwin County. It serves as an outlying landing field for naval aviation training, primarily supporting touch-and-go and field carrier landing practice (FCLP) operations associated with nearby Naval Air Station Whiting Field. The facility is not open to commercial or general public aviation and has no passenger terminals or scheduled airline service. It functions strictly as a training asset for U.S. Navy student pilots learning carrier landing techniques and basic flight maneuvers. Summerdale NOLF is one of several outlying fields in the Gulf Coast region that support the high volume of pilot training conducted under the Naval Aviation Schools Command. Its flat terrain and proximity to the Gulf of Mexico make it well-suited for low-altitude training operations.
