The modern Oregon ANG received federal recognition on 30 August 1946 as the 142nd Fighter Group at Portland Municipal Airport, Portland. Its 123rd Fighter Squadron was equipped with F-51D Mustangs and its mission was the air defense of the state. 18 September 1947, however, is considered the Oregon Air National Guard's official birth concurrent with the establishment of the United States Air Force as a separate branch of the United States military under the National Security Act
Today the 142nd Fighter Wing at Portland and the 173rd Fighter Wing at Klamath Falls both fly the F-15 Eagle with a homeland defense mission. After the 11 September 2001 terrorist attacks on the United States, elements of every Air National Guard unit in Oregon has been activated in support of the Global War on Terrorism. Flight crews, aircraft maintenance personnel, communications technicians, air controllers and air security personnel were engaged in Operation Noble Eagle air defense overflights of major United States cities. Also, Oregon ANG units have been deployed overseas as part of Operation Enduring Freedom in Afghanistan and Operation Iraqi Freedom in Iraq as well as other locations as directed.
