The F-100 was also the first Wild Weasel air defense suppression aircraft, whose specially trained crews were tasked with locating and destroying enemy missile defenses. Four F-100F Wild Weasel Is were fitted with an APR-25 vector radar homing and warning receiver, IR-133 panoramic receivers with greater detection range, and KA-60 panoramic cameras. The APR-25 could detect early-warning radars and emissions from SA-2 Guideline tracking and guidance systems. These aircraft deployed to Korat Royal Thai Air Force Base, Thailand, in November 1965, began flying combat missions with the 388th Tactical Fighter Wing in December. They were joined by three more aircraft in February 1966. All Wild Weasel F-100Fs were eventually modified to fire the AGM-45 Shrike anti-radiation missile.
