This baseline SLAM missile system was developed and fielded in less than 48 months, and was successfully employed by F/A-18 and A-6 aircrews in Desert Storm even before operational testing had begun. Because of emerging operational requirements, the Standoff Land Attack Missile (SLAM) was developed as a derivative of the Harpoon. SLAM-ER roots go back to the original Harpoon anti-ship missile placed in the fleet in the late 1970s.

The SLAM-ER is extremely accurate, and has the best Circular Area of Probable (CEP) in the U.S. It can also be controlled by the F/A-18E/F. The SLAM-ER can be launched and controlled by F/A-18C/D, P-3s, and S-3 platforms. The SLAM-ER is also the first weapon system with a moving target capability from standoff ranges. SLAM-ER was the first weapon to feature Automatic Target Acquisition (ATA), a revolutionary technological breakthrough that helps improve target acquisition in cluttered scenes, overcomes most IR countermeasures, and mitigates the effects of environmentally degraded conditions. Most significant characteristics are: a highly accurate, GPS-aided guidance system an imaging infrared seeker and two-way data link with the AWW-13 Advanced Data Link pod for Man-In-The-Loop (MITL) 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 and a user-friendly interface for both MITL control and mission planning. SLAM-ER provides an effective, long range, precision strike option for both pre-planned and Target of Opportunity attack missions against land and maneuvering ship targets. SLAM-ER addresses the Navy's requirements for a precision-guided Standoff Outside of Area Defense (SOAD) weapon.

The AGM-84K Standoff Land Attack Missile-Expanded Response (SLAM-ER), an evolutionary upgrade to the combat-proven SLAM, is an air-launched, day/night, adverse weather, over-the-horizon, precision strike missile.
