The AGM-84E SLAM (Standoff Land Attack Missile) was a subsonic, over-the-horizon air-launched cruise missile that was developed by McDonnell Douglas from the AGM-84 Harpoon anti-ship missile.[2] The SLAM was designed to provide all-weather, day and night, precision attack capabilities against stationary high-value targets[1] as well as ships in port.[3]

Design

[edit]

Except for new technologies in the guidance and seeker sections, which included a Global Positioning System receiver, a modified AGM-65F Maverick missile IIR Seeker, and a modified Walleye datalink, all of the missile hardware came directly from the Harpoon missile.[4] SLAM missile uses an inertial navigation system, which is supplemented by Global Positioning System (GPS) input, and it also uses infrared homing terminal guidance.[1] It could also be guided by any aircraft carrying the AN/AWW-9B and AN/AWW-13 datalink pods.[2] The missile however was unable to avoid terrain, meaning that to attack a target, there had to be no obstacles in the path of the missile.[5]

Deployment in the Gulf War

[edit]

Developed in 48 months, three SLAMs were successfully employed during the Persian Gulf War, when they were used to strike Iraqi targets. These strikes, made exclusively by the few A-6E SWIP Intruders assigned to VA-75 on the USS John F. Kennedy (CV-67),[5] were before official operational testing of the new missile had begun.[6] Only five SLAMs were carried to the war, all on the Kennedy.[7] They had also been only been recently moved to carrier.[8]

The first time the SLAM was used in combat came on January 18, 1991, when two SLAMs, fired two minutes apart, were launched by an A-6E SWIP Intruder from VA-75 towards a Hydro-electric plant north of Baghdad on the Tigris River, specifically the power house and turbines.[9][7] This plant was targeted because it powered the Al-Qa'im superphosphate fertilizer plant (nicknamed 'Big Al'), known to produce yellowcake for uranium enrichment. The SLAMs were guided by an A-7E Corsair II from VA-72 (also from the Kennedy) via the use of a Datalink pod.[9][7][8][5]

Although GPS guidance could have done the job without the need of the Corsair II, the Navy need the Corsair II to allow the first SLAM to blast a hole, allowing the 2nd SLAM to fly through the hole and cause damage. The last SLAM used in the war was fired that same night against a dam known to generate electricity near Al Qa'im. The dam was reportedly disabled with that single hit.[7] The strike itself was also successful in that it enabled the Intruder to attack without entering the Missile Engagement Zone of Al-Qa'im.[8]

1990s and retirement

[edit]

Several months after the Gulf War, the SLAM was officially approved for full production on June 28, 1991.[3]

The SLAM was also used during NATO airstrikes in Bosnia during operations Deny Fly (1993-1995) and Deliberate Force (1995).[1] 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.[10][11]

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.[1]
