The AN/MSQ-77 was a United States Air Force]] ground-based system for directing gravity bomb|bombing]] of targets, also known as COMBAT SKYSPOT. It was developed from the AN/MSQ-35 radar]] used for verifying the accuracy of Strategic Air Command]] bombers in training. For combat operations, it had a 175-mile range, which had to be in line of sight to the target; this made high ground preferable for its installation. AN/MSQ-77 systems were extensively used during the Vietnam War]], most importantly to direct hombing from B-52]] heavy bombers at high altitude. It was also used to direct tactical aircraft during all weather and during darkness, in situations including attacks on supply lines, close air support]], parachute delivery of supplies and personnel, and combat search and rescue]]. It could back up Ground Controlled Approach]] landing systems for aircraft with damaged onboard electronics, and also mark areas to attack, relative to an airborne spotter that discovered a new target. While more accurate attack direction systems replaced it in that role, it continued to be used for training until the AN/TPQ-43]] system was introduced.
