and brought to active duty on March 2, 1951. It was assigned to the Air Defense Command Western Air Defense Force. Afterwards, it was then reassigned to the federalized Washington Air National Guard's 142nd Fighter-Interceptor Wing in April 1951, and moved to O'Hare International Airport, Chicago, Illinois, by May of the same year. The organization was then re-designated as the 142nd Fighter-Interceptor Group on May 1, 1951. At O'Hare International Airport, the 142nd Fighter Group controlled the 62nd Fighter-Interceptor Squadron flying F-86A Sabre interceptors. The group was inactivated on 6 February 1952, being replaced by the 4706th Air Defense Wing. Cold War Resuming its peacetime mission of the air defense of Oregon, Air Defense Command (ADC) upgraded the groups capabilities by allocating the F-94A Starfire all-weather interceptor. With this new aircraft, the mission of the 123rd Fighter-Interceptor Squadron changed from day interceptor to day and night all-weather interceptor. In 1957 the 123rd again upgraded to the improved F-89J Scorpion, and again upgraded to the supersonic F-102A Delta Dagger in 1966. In the summer of 1958, the 142nd implemented the ADC Runway Alert Program, in which interceptors of the 123rd Fighter-Interceptor Squadron were committed to a five-minute runway alert 24/7. The runway alert continues to this day. In 1972 it received the Mach-2 F-101B Voodoo. As an example of the unit's readiness and capability, in 1976, the unit won top honors at a pair of Aerospace Defense Command (ADC) competitions, the Weapons Loading Competition and the famous William Tell Air Defense Competition. In William Tell 1976, the 142nd garnered first place in the F-101 category and Lieutenant Colonel Don Tonole and Major Brad Newell captured the overall "Top Gun" title flying the McDonnell F-101B Voodoo. After the inactivation of Aerospace Defense Command in 1979 and the reassignment to Tactical Air Command (ADTAC), the 123rd began receiving F-4C Phantom II aircraft used in the interceptor mission beginning in 1981. Success came again at William Tell 1984 when the unit placed first in the F-4 category flying the McDonnell-Douglas F-4C Phantom II and beat many of its F-15 Eagle and F-106 Delta Dart rivals in the overall competition. Majors Ron Moore and Bill De Jager were the overall F-4 "Top Guns" of the competition. In 1985, as part of the retirement of the F-4C from the inventory, the Oregon Air National Guard began to receive F-15A Eagles from active-duty units receiving the upgraded
