The F-105G was the designation given to Wild Weasel F-105Fs which were fitted with greatly improved avionics. The designation EF-105F was temporarily applied to these aircraft, but their designation was eventually changed to F-105G. The first F-105Gs went to the 357th TFS at Tahkli RTAFB during the second half of 1967. The electronic warfare officer (EWO) in an F-105G ran all the new electronic equipment for locating SAM or anti-aircraft artillery (AAA) radars, warning of SAM launches, and sending Shrike missiles down the radar beams.
