tragedy struck the fledgling unit. En route to pick up the adjutant general in Helena, the A-26 Invader Lt. Col. Sperry was flying went down in a heavy snowstorm. The wreckage could not be found until the following summer. Aboard also was Sgt. Charles Glover, for whom the street along the east side of building 64 is named. On 1 April 1951, the unit was activated for duty in South Korea. Personnel were sent to Moody AFB, Ga., and ten F-51s were shipped to Korea. The squadron became a F-51D Fighter-Bomber training unit. The 186th was returned to Montana State control in November 1952 and on 1 January 1953, the squadron was reformed at Gore Field with Captain Rodger D. Young as Commander. Promoted to Colonel, Young served as Group Commander until 1966 when he was promoted to Brig. General and Chief of Staff for Air for the 120th Fighter Group until his retirement in 1973. Under the Command of Brig Gen. Young the unit flew the F-86, F-94, F-89, F102 and F-106 fighters. After the Korean War, the squadron was equipped with the long-range F-51H Mustang and became a part of Air Defense Command. The unit received its first jet aircraft in December 1952, a T-33 Shooting Star. In early 1953 it was equipped with F-86A Sabre jet interceptors. The squadron was redesignated the 186th Fighter-Interceptor Squadron on 1 November 1953 and adopted the "Charlie Chicken" patch. By July 1955 the transition from the F-51H Mustang to the F-86A Sabre was complete. On 1 July 1955, the 186th was authorized to expand to a group level, and the 120th Fighter Group (Air Defense) was established by the National Guard Bureau. The 186th FIS becoming the group's flying squadron. Other squadrons assigned into the group were the 120th Headquarters, 120th Material Squadron (Maintenance), 120th Combat Support Squadron, and the 120th USAF Dispensary. Also in 1955, the F-86A day interceptors were replaced by the F-94A Starfire all-weather interceptor. In 1958, the 120th implemented the ADC Runway Alert Program, in which interceptors of the 186th FIS were committed to a five-minute runway alert, a task that would last for 38 years. The arrival of the F-102 Delta Dagger in 1966 ushered in the supersonic age. In 1968 Air Defense Command was re-designated as Aerospace Defense Command (ADCOM).
