Stewart Air National Guard Base is the home of the 105th Airlift Wing (105 AW), an Air Mobility Command (AMC)-gained unit of the New York Air National Guard and "host" wing for the installation. The former Stewart Air Force Base is also known as Newburgh-Stewart IAP and Stewart International Airport, while the military portion of this now-joint civil-military airport is known as Stewart Air National Guard Base (Stewart ANGB). The base is named in honor of 19th century Scottish-born sea captain, Lachlan Stewart, and his son, who donated the land it now occupies.
