With its supersonic F-106s, the squadron intercepted Russian bombers on missions over the Bering Sea. Then, in June 1969, with tensions mounting following the Pueblo Incident and the downing of an EC-121 electronic observation plane by North Korea, the squadron deployed to Osan AB, South Korea, for six months. It then replaced the 75th FIS at Wurtsmith AFB, Michigan until 1 July 1971. At that time, the squadron was redesignated the 94th Tactical Fighter Squadron, reassigned to Tactical Air Command, and reunited with the 27th and 71st Squadrons under the 1st Tactical Fighter Wing (1 TFW), flying the F-4E. The 94th assumed the duties of a Replacement Training Unit (RTU), providing F-4 aircrews for operational combat squadrons.
