The 121st Tactical Fighter Wing were called to active duty for a period of twelve months on 1 October. When activated, the federalized wing consisted of three operational units, the 162d TFS at Springfield, the 164th TFS at Mansfield, and the 166th at Lockbourne. The 112th TFS at Toledo and the 145th ATS at Akron were temporally attached directly to Ohio ANG Headquarters at Columbus for the period of federalization. The mission of the activated 121st TFW was to reinforce the United States Air Forces in Europe (USAFE), and deploy to Étain-Rouvres Air Base, France, a standby USAFE base. However, due to funding shortages, only 26 F-84F Thunderstreaks of 166th TFS were deployed to France, although several ground support units from the 162nd and 164th were also deployed.
