RAAF Station Williamtown was established on 15 February 1941 to provide protection for the strategic port and steel manufacturing facilities of the Hunter Region. The base was initially served by four runways, each 1,100 m (3,600 ft) in length to meet the needs of the Williamtown Flying School. The School consisted of 62 buildings which accommodates 366 officers and men.
In 1961 the squadron of Meteors were replaced with the Dassault Mirage aircraft. On-base facilities were gradually expanded post war and through until the late 1960s.
In 1983 the role of Williamtown was upgraded to a tactical fighter base in preparation of the replacement of the Mirages with 75 F/A-18 Hornets in 1989. The following year Williamtown became headquarters for the Tactical Fighter group and acquired new headquarter buildings, hangars, workshops, stores, medical facilities and a base chapel.
RAAF Base Williamtown has most of the facilities you would expect to find in a small town, including sporting fields, recreation facilities, cinema and even a fortnightly newspaper highlighting activities around the Base and outside community.
In addition to its military units, RAAF Williamtown is the home to Fighter World, a museum dedicated to Australian fighter aircraft.
