For much of the Cold War period, Grumman was the largest corporate employer on [[Long Island]].<ref>{{cite web |title=Facts You Didn't Know About Long Island Businesses |url=https://www.newsday.com/business/facts-you-didn-t-know-about-long-island-businesses-1.9812995 |website=Newsday |access-date=28 January 2019 |url-status=dead |archive-url=https://web.archive.org/web/20190128083423/https://www.newsday.com/business/facts-you-didn-t-know-about-long-island-businesses-1.9812995 |archive-date=28 January 2019}}</ref> Grumman's products were considered so reliable and ruggedly built that the company was often referred to as the "'''Grumman Iron Works'''".<ref>Skrula and Gregory 2004</ref>

As the company grew, it moved to [[Valley Stream, New York]], then [[Farmingdale, New York]], finally to [[Grumman Bethpage Airport|its facility in]] [[Bethpage, New York]], with the testing and final assembly at the {{convert|6000|acre|km2|adj=on}} [[Naval Weapons Industrial Reserve Plant, Calverton|Naval Weapons Station]] in [[Calverton, New York]], all located on Long Island. At its peak in 1986 it employed 23,000 people on Long Island<ref>{{cite news |url=https://query.nytimes.com/gst/fullpage.html?res=9A06E7D91F3AF93BA35750C0A962958260 |title=Long Islanders Shocked by Grumman's Merger |work=The New York Times |date=March 8, 1994 |last=McQuiston |first=John T.}}</ref> and occupied {{convert|6000000|sqft|m2}} in structures on {{convert|105|acre|km2}} it leased from the U.S. Navy in Bethpage.<ref name="nyt_dec28_97">{{Cite news |last=Shaman |first=Diana |date=1997-12-28 |title=Commercial Property/Selling Off Northrop Grumman's Surplus; Cablevision Takes Last of the Grumman Buildings |url=https://www.nytimes.com/1997/12/28/realestate/commercial-property-selling-off-northrop-grumman-s-surplus-cablevision-takes.html |access-date=2024-06-24 |work=The New York Times |language=en-US |issn=0362-4331}}</ref>

The end of the Cold War at the beginning of the 1990s reduced defense spending and led to a wave of mergers as aerospace companies shrank in number; in 1994 [[Northrop Corporation|Northrop]] bought Grumman for $2.1 billion to form [[Northrop Grumman]],<ref name="nyt_dec28_97"/> after Northrop topped a $1.9 billion offer from [[Martin Marietta]].<ref>{{cite news |url=https://query.nytimes.com/gst/fullpage.html?res=9902E7DA113FF936A35757C0A962958260&sec=&spon=&pagewanted=print |title=Northrop Bests Martin Marietta to Buy Grumman |website=The New York Times |date=April 5, 1994 |last=Sims |first=Calvin}}</ref>

The new company closed almost all of its facilities on Long Island and converted the Bethpage plant to a residential and office complex, with its headquarters becoming the corporate headquarters for [[Cablevision]] and the Calverton plant being turned into a business/industrial complex. Former aircraft hangars have become [[Grumman Studios]], a film and television production center. A portion of the airport property has been used for the Grumman Memorial Park.<ref name="Grumman facts"/>
