Calverton Executive Airpark is a general aviation facility located in Calverton, New York, on Long Island's North Fork. It occupies land that was formerly part of the Grumman/Northrop Grumman Calverton facility, a major aircraft manufacturing and test site that was active during and after World War II. The airpark serves private pilots, charter operations, and small aircraft, providing an accessible reliever airport for the eastern Long Island region. It does not handle scheduled commercial airline service. The surrounding area is known for its vineyards and rural character, making the airport a convenient access point for visitors to the East End of Long Island.
