Groton New London Airport (KGON) is a public, tower-controlled airfield on the Connecticut shoreline near Long Island Sound, serving the Groton, Mystic and New London area. It offers an ILS approach and a mix of general aviation and business traffic, making it a useful VFR and IFR destination for pilots exploring southeastern Connecticut.
Groton New London Airport lies on the Connecticut coast close to the towns of Groton, Mystic and New London, and is operated as a public airport under the Connecticut Airport Authority. It is presently used for general aviation and business flying rather than scheduled airline service, though there has been recent local discussion about the field's capacity to support commercial flights again. For a simulator pilot, its coastal position, control tower, and instrument approach make it an interesting and instructive stop along the Connecticut shoreline.
The airport sits on the Connecticut coastline near Long Island Sound, within reach of Providence Approach and Departure control, which operates on 125.75 MHz. It is a tower-served field, with ground movements handled separately from tower frequency. Its position places it close to the towns of Groton, Mystic and New London, useful reference points for a pilot transiting the shoreline.
Groton New London has two physical runways. Runway 05/23 is 4,985 feet long with a hard surface and runway lighting, and is equipped with an ILS on the 05 approach. Runway 15/33 comprises two hard-surfaced, lit strips of slightly differing published length, 3,687 feet for runway 15 and 3,782 feet for runway 33. Field elevation is 3 feet above mean sea level.
The airport is served by a control tower, with tower and CTAF both listed on 125.6 MHz, and ground control on 121.65 MHz. Clearance delivery operates on 119.85 MHz, and ATIS broadcasts on 127 MHz. Providence Approach/Departure works traffic on 125.75 MHz. Additional frequencies published for the field include an operations channel (Army National Guard Ops) on 126.2 MHz and a Bridgeport radio outlet on 122.1 MHz. The field's ILS supports an instrument approach to runway 05.
The airport does not currently host scheduled airline service, though the Connecticut Airport Authority has stated the field could support commercial flights and is reported to be in the middle of renovations, according to a 2026 local news report. It continues to operate as a general aviation field with a functioning control tower and instrument approach capability.
