After Air Defense Command closed its facilities in 1966, Portland AFB was inactivated and the military facilities were reduced in size. The 142nd Fighter Interceptor Group became the host unit of the military facilities at Portland International Airport. Around 1990, the Air Force facilities were designated as Portland Air Reserve Station, being a secure facility on the south side of the main airport runway and remaining a very active presence at the airport. Following a major overhaul of the USAF organizational structure in 1992, the 142d was redesignated as the 142d Fighter Wing (142 FW) and became an Air National Guard unit operationally-gained by the Air Combat Command (ACC).
