After three years without any permanent flying units, in 1961 Chambley Air Base was reactivated as part of Operation Tack Hammer, the United States response to the Berlin Crisis of 1961. On 1 October 1961, as a result of the crisis, the mobilized Indiana Air National Guard 122d Tactical Fighter Wing was deployed to Chambley from Baer Field, Fort Wayne, Indiana. When activated, the 122d consisted of three tactical fighter squadrons, the 112th at Toledo Express Airport, Ohio; the 113th at Hulman Field, Terre Haute, and the 163d at Baer Field. The deployed wing was designated the 7122d Tactical Wing while in France. By 1 December the ground support units arrived and the 7122d prepared for an estimated overseas deployment of 10 months.
