Naval Air Station Midway Island, also known as NAS Midway, Naval Air Facility Midway, and NAF Midway, was a U.S. Naval Air Station in the Midway Atoll, the northernmost group of the Hawaiian archipelago. It was in operation from 1941 to 1993, and played an important role in trans-Pacific aviation during those years. Through its lifetime, the facility was variously designated as a Naval Air Station, a Naval Air Facility, and a naval base. It was finally closed on October 1, 1993.
