Standoff Land Attack Missile Expanded Response (SLAM-ER)

The AGM-84K SLAM-ER is an air-launched, day/night, adverse-weather, over-the-horizon, precision strike missile that provides a long range option for pre-planned and target of opportunity missions against land and sea targets.  SLAM-ER roots go back to the original Harpoon anti-ship missile placed in fleet service in the late 1970s. Because of emerging operational requirements, the SLAM was developed as a derivative of the Harpoon.  SLAM-ER incorporates a global positioning system-aided guidance system; imaging infrared seeker and two-way data link for man-in-the-loop control; improved missile aerodynamic performance characteristics that allow both long range and flexible terminal attack profiles; an ordnance section with good penetrating power and lethality. SLAM-ER uses automatic target acquisition, a revolutionary technology that helps improve target acquisition in cluttered scenes, overcomes most infrared countermeasures and mitigates the effects of environmentally degraded conditions. The SLAM-ER can be launched and controlled by F/A-18C/D/E/F and P-3 platforms.
