NAS Whidbey Island KNUW Map Art Naval Air Station Whidbey Island is a naval air station of the United States Navy located on two pieces of land near Oak Harbor, on Whidbey Island, in Island County, Washington. The main portion of the base, Ault Field, is about three miles north of Oak Harbor. The other section, called the Seaplane Base for the PBY Catalina flying boats once based there, holds most of the island’s Navy housing as well as the air station’s main Navy Exchange and DeCA Commissary. The NASWI commanding officer also has command of a lightly used satellite airfield, Naval Outlying Landing Field (NOLF) Coupeville, on central Whidbey Island at 48°11′24″N 122°37′48″W, roughly nine miles south of Ault Field.
