Groton–New London Airport (IATA: GON, ICAO: KGON, FAA LID: GON) is a state-owned public-use airport located three nautical miles (6 km) southeast of the central business district of Groton, a town in New London County, Connecticut, United States.

[3] Groton-New London Airport has been used by several presidents speaking at the commencement of the nearby US Coast Guard Academy.

Through all of 1943, a total of 10 squadrons of P-47 Thunderbolt fighter groups trained at the field, with the last unit departing for overseas combat in January 1944.

Groton–New London Airport covers an area of 489 acres (198 ha) at an elevation of 9.1 feet (2.8 m) above mean sea level.

For the 12-month period ending December 31, 2009, the airport had 38,582 aircraft operations, an average of 105 per day: 87% general aviation, 10% military, and 4% air taxi.

[4] Groton-New London has been home to the Connecticut National Guard’s 1109th Theater Aviation Support Maintenance Group (abbreviated as "TASMG") since August 1st 1979 when the groups location was changed to the airport when it was converted and redesignated from "Detachment 1, 1109th Transportation Company" to Detachment 1, Groton Connecticut Army Aviation Classification and Repair Depot.

In 2012, faced with declining demand for services, the two proposed merging their Groton operations as a joint venture called Mystic Jet Center.

In January 2013, the U.S Department of Justice's Antitrust Division announced that it would not interfere with the merger, citing sufficient competition from nearby airports.
