Wild Weasel is a code name given by the United States Air Force (USAF) to an aircraft of any type equipped with anti-radiation missiles and tasked with the suppression of enemy air defenses (SEAD): destroying the radar and surface-to-air missile (SAM) installations of enemy air defense systems. The task of a Wild Weasel aircraft is to bait enemy anti-aircraft defenses into targeting it with their radars, whereupon the radar waves are traced back to their source, allowing the Weasel or its teammates to precisely target it for destruction.
The Wild Weasel concept was developed by the USAF in 1965 during the Vietnam War after the introduction of Soviet SAMs and their downing of American strike aircraft participating in Operation Rolling Thunder in the skies over North Vietnam. The program was headed by General Kenneth Dempster.
"The first Wild Weasel success came soon after the first Wild Weasel mission 20 December 1965 when Captains Al Lamb and Jack Donovan took out a site during a Rolling Thunder strike on the railyard at Yen Bai, some 75 mi (120 km) northwest of Hanoi."
Wild Weasel tactics and techniques were later adapted by other nations...
