In July 1960, the 125th converted from the F-86D to the all-weather, supersonic F-102A and F-102B Delta Dagger. In 1968, following completion of the new Jacksonville International Airport, the 125 FIG relocated from the Jacksonville Imeson Airport to a newly constructed military installation, the current Jacksonville Air National Guard Base, at the new airport. With the concurrent closure of Imeson Airport to all flight operations and its conversion to an industrial park, the 125 FIG vacated its former facilities and turned over same to the City of Jacksonville.
