Suppression of Enemy Air Defenses (SEAD, pronounced ), also known in the United States as "Wild Weasel" and (initially) "Iron Hand" operations, are military actions to suppress enemy surface-based air defenses, including not only surface-to-air missiles (SAMs) and anti-aircraft artillery (AAA) but also interrelated systems such as early-warning radar and command, control and communication (C3) functions, while also marking other targets to be destroyed by an air strike. Suppression can be accomplished both by physically destroying the systems or by disrupting and deceiving them through electronic warfare. In modern warfare, SEAD missions can constitute as much as 30% of all sorties launched in the first week of combat and continue at a reduced rate through the rest of a campaign. One quarter of American combat sorties in recent conflicts have been SEAD missions. Despite generally being associated with aircraft, SEAD missions may be performed using any means, including through actions by ground forces.

The United States Air Force, Navy, and Marine Corps carried out air strikes, code-named Operation El Dorado Canyon, against Libya on 15 April 1986 in retaliation for the West Berlin discotheque bombing ten days earlier, which U.S. President Ronald Reagan blamed on Libyan leader Muammar Gaddafi. There were 40 reported Libyan casualties; one U.S. plane was shot down. One of the claimed Libyan deaths was of a baby girl, reported to be Gaddafi's daughter, Hana Gaddafi. However, there are doubts as to whether she was really killed, or whether she truly existed.
