Naval Weapons Industrial Reserve Plant, Calverton

Naval Weapons Industrial Reserve Plant, Calverton (NWIRP) was a government-owned, contractor-operated (GOCO) facility which had the mission of designing, fabricating, and testing prototype aircraft from 1956 until 1996, in Riverhead, New York, United States.

The Naval Weapons Industrial Reserve Plant (NWIRP) is located on Grumman Boulevard in Calverton, New York.
