Wild Weasel is a code name given by the United States Armed Forces, specifically the US Air Force, to an aircraft, of any type, equipped with radar-seeking missiles and tasked with destroying the radars and SAM installations of enemy air defense systems. "The first Wild Weasel success came soon after the first Wild Weasel mission 20 December 1965, where both air crewmen were either captured or killed, when Captains Al Lamb and Jack Donovan took out a site during a Rolling Thunder strike on the railyard at Yen Bai, some 75 miles northwest of Hanoi."
