Calverton Executive Airpark is a public-owned private-use airport located three miles (5 km) west of the central business district of Calverton, in Suffolk County, New York, United States. It is owned by the Town of Riverhead.
It was formerly the Naval Weapons Industrial Reserve Plant which was owned by the United States Navy and used to assemble, test, refit and retrofit jets built by the Grumman Corporation on Long Island.
The airport covers an area of which contains two asphalt and concrete runways: 14/32 measuring 10,000 x 200 feet (3,048 x 61 m) and 5/23 measuring 7,000 x 200 feet (2,133 x 61 m). Older aerial photos show both runways marked with X's which indicate they are closed, but more recent photos show runway 14/32 with the X's removed and that runway is operational according to the town's airport rules and regulations.
The airport is lightly used with most planes using the nearby Francis S. Gabreski Airport. Its most visible commercial air tenant is Sky Dive Long Island which since 2000 has been using the airport for its skydiving operations.
The Navy was to build among other things a runway. It is labeled on topographic maps as Grumman Peconic River Airport with an FAA code of CTO.
The Grumman site consisted of "Plant Six," where final assembly of F-14s, A-6s, EA-6Bs, and E-2Cs, and "Plant Seven," Flight Test.
In 1965 New York Governor Nelson Rockefeller proposed converting the airport into the fourth New York City metropolitan airport joining Laguardia Airport, John F. Kennedy Airport and Newark Airport. The proposal was abandoned following opposition from both Grumman and local residents.
In 1974 when the two other National Cemeteries on Long Island (Cypress Hills National Cemetery and Long Island National Cemetery) were running out of space, the Navy was approached about donating its undeveloped land north of Route 25 for a cemetery. On December 7, 1977, a tract was donated to form Calverton National Cemetery. More land would be donated by the Navy in 2000 bringing the total to making it the largest national cemetery in the United States (and also the busiest).
In 1996 the wreckage of TWA Flight 800 which had crashed about south of the airport was reconstructed in a hangar.
Grumman had merged with Northrop in 1994 and the new firm eliminated almost all operations on Long Island and the final Grumman affiliation with Calverton was in 1996.
In September 1998, the bulk of the developed land, , at the airport was donated to Riverhead. Another was donated to the New York Department of Environmental Conservation for wildlife management.
In the 1998 transactions East End Aircraft Long Island Corporation was given 10 acres on Highway 25 which it is developing into the Grumman Memorial Park and Aerospace Museum.
As of January 2006, the Navy still owns 358 acres (mostly areas requiring environment clean up) at the site.
In January 2008 the Riverhead Town Board with newly elected officers signed a deal to sell the airport for $155 million to Riverhead Resorts to build the ski mountain and tear up the airport runway and replace it with a lake overruling a December vote to give the NASCAR track the go ahead.
It will take up to three years to get the necessary environmental permits and the proposed opening date of the project is 2012.
A portion of the facility, including the industrial core, is also being developed as an industrial/office park.
As discussions over whether the airport could be developed the New York State Department of Environmental Conservation announced in February 2008 that endangered Short-eared Owls and Northern Harriers had been spotted at the airport which would prompt the DEC to make the ultimate decision the environmental impact of the development.
