Operation Southern Watch was an air-centric military operation conducted by the United States Department of Defense from Summer 1992 to Spring 2003. United States Central Command's Joint Task Force Southwest Asia (JTF-SWA) had the mission of monitoring and controlling the airspace south of the 32nd Parallel (extended to the 33rd Parallel in 1996) in southern and south-central Iraq during the period following the end of the 1991 Gulf War until the 2003 invasion of Iraq.
