The SLAM was also used during United Nations air raids in Bosnia before "Operation Joint Endeavor". An F/A-18C (N) Hornet from VFA-151 in February 1999 tested the SLAM's special GPS only guidance mode against a simulated SA-10 radar van in a target complex located on San Nicolas Island. In the year 2000, the SLAM was replaced in service by the AGM-84H SLAM-ER (Standoff Land Attack Missile Expanded Response), which had numerous new capabilities including increased target penetration and nearly twice the range of the older AGM-84E SLAM.
