The Aviationist:  “During the Vietnam War the main threat to the strike packages was the V-750 (S-75) Dvinathe first effective Soviet surface-to-air missile (SAM). Better known by the NATO designation SA-2 Guideline . . . . To suppress and destroy this threat, the U.S. Air Force countered with the courage and skill of the Wild Weasels, who not only flew some of the most dangerous missions in Southeast Asia but also became pioneers in Suppression of Enemy Air Defenses (SEAD) operations.  As we have already explained, the first Wild Weasel sorties were flown in the fall of 1965 and were planned around the “hunter-killer” concept by using two aircraft: one had to locate the enemy SAM batteries while the other had to physically destroy them.  The first, tasked to hunt the SAM airplane, was the F-100F while the killer aircraft was the F-105.  In January 1966 the two seat F-105F was chosen to replace the F-100F to improve the performance of both members of the team.”
