Acronym for Standoff Land Attack Missile. This is a weapon adapted from the AGM-65 Harpoon - it is a small rocket/cruise missile with a television relay system in the nose and remote control capabilities. It was used to good effect in Operation Desert Storm by Allied aircrew; the CNN shots of weapon point-of-view rapidly approaching a target and then cutting to static were mostly from SLAMs. They carry a multi-hundred pound high explosive warhead and are dropped (and guided) from aircraft such as the F-18 Hornet and the A-6E Intruder. It can trace its lineage all the way back to the World War II German weapon Fritz-X, which was really the exact same system with more primitive components: a radio-guided, television-relay air-breathing missile dropped and controlled from an aircraft.
