Groton New London Airport — Groton, United States

GON is Groton-New London Airport, located in southeastern Connecticut near the cities of Groton and New London. The airport primarily serves general aviation, corporate flights, and has historically supported activity tied to the region's strong submarine and naval industry, including nearby Naval Submarine Base New London and Electric Boat's shipbuilding operations. Scheduled commercial airline service has been intermittent over the years, with GON more consistently functioning as a base for private aircraft, flight training, and charter operations. The surrounding area, including Mystic Seaport and the Connecticut coastline, draws some tourism traffic as well. GON's role reflects the broader pattern of smaller regional Connecticut airports operating alongside the busier hubs in Hartford and nearby New York airports.
