In February 1997 the 121st Expeditionary Fighter Squadron (121st EFS) was first formed from 113th personnel and aircraft and deployed to Incirlik Air Base, Turkey in support of Operation Northern Watch (ONW). Operation Northern Watch was a US European Command Combined Task Force (CTF) who was responsible for enforcing the United Nations mandated no-fly zone above the 36th parallel north in Iraq. This mission was a successor to Operation Provide Comfort which also entailed support for the Iraqi Kurds. The 121st EFS returned to Andrews in April 1997. The 121st EFS was again formed in January 1998 when the Wing was tasked with a second Operation Northern Watch deployment to Incirlik Air Base. This time the deployment was only for a month with less than 100 personnel being deployed.
