Stewart International Airport: From West Point Airfield to Cold War Fortress

The story of Stewart Airport begins with a donation of land and a dollar. In nineteen thirty, a Newburgh businessman named Thomas Stewart persuaded his uncle Samuel Stewart to give the city land for an airport. Four years later, Douglas MacArthur, then serving as superintendent of the United States Military Academy at West Point, proposed using the new airfield to train cadets in aviation. The city sold the land to the military for one dollar, and the arrangement that would define Stewart for the next half century began.

During World War Two the airport became a full military installation, training Army Air Forces pilots alongside West Point cadets. After the war it became Stewart Air Force Base, absorbed by the newly independent Air Force in nineteen forty-eight and assigned both continued cadet training and a frontline combat role. As the Cold War deepened, Stewart became part of the SAGE continental air defense system. A SAGE direction center opened at the base in nineteen fifty-eight, housing one of the massive AN/FSQ-Seven computers that processed radar data from across the northeast and directed interceptor aircraft against any incoming Soviet threat. Alert hangars at the end of the runway kept F-eighty-six Sabres and later F-one-oh-two Delta Daggers on five-minute standby, ready to scramble toward the Hudson Valley corridor.

The Air Force transferred the base to New York State in nineteen seventy, and the state converted it to a commercial airport with a military reserve component. American Airlines began commercial service in nineteen ninety. In the year two thousand the airport was leased to the British firm National Express Group, and the Port Authority of New York and New Jersey took over operations in two thousand seven. The long runway, the Cold War hangars, and the SAGE infrastructure remain as physical traces of the decades when this corner of the Hudson Valley was considered one of the key defensive positions between a Soviet bomber and New York City.
