Combat Skyspot was the ground-directed bombing (GDB) operation of the Vietnam War by the United States Air Force using Bomb Directing Centrals and by the United States Marine Corps using Course Directing Centrals ("MSQ-77 and TPQ-10 ground radars"). Combat Skyspot's command guidance of B-52s and tactical fighters and bombers—"chiefly flown by F-100's"—at night and poor weather was used for aerial bombing of strategic, close air support, interdiction, and other targets. Using a combination radar/computer/communications system ("Q" system) at operating location in Southeast Asia, a typical bombing mission (e.g., during Operation Arc Light with a "cell" of 3 Boeing B-52 Stratofortresses) had an air command post turn over control of the mission to the radar station, and the station provided bomb run corrections and designated when to release bombs. Planning of Vietnam GDB missions included providing coordinates with accuracy to the radar sites, handoff of the bomber from air controllers (e.g., a DASC) to the site, tracking the aircraft by radiating the bomber (e.g., activating the 400 Watt Motorola SST-181 X Band Beacon Transponder),〔http://www.navy-radio.com/manuals/AN-NAVY.HTM〕 and radioing of technical data from the aircrew to the radar site such as the airspeed/heading for the central to estimate wind speed on the bomb(s). With the bomber near a designated "Initial Point" the GDB site would begin a radar track (Bomb Directing Centrals would calculate a computer track and solve the "bomb problem" for the aircraft position.) For B-52 missions the site personnel verbally transmitted guidance commands to the aircraft crew by radio (lead aircraft for multi-ship formations) to adjust the flight path toward an eventual release point for the actual bomb(s). Site personnel verbally directed release of the ordnance from the aircraft by voice countdown. This was a manual process requiring training, practice and adherence to procedure. Both the site and aircrew were authorized to "withhold" release at any point if doubt arose. All communications were tape recorded by the aircrew for post strike debriefing. ==Development==
Similar to World War II GDB and Korean War GDB, Combat Skyspot was planned during 1965 development of the Reeves AN/MSQ-77 Bomb Directing Central with a new integrating ballistic computer using vacuum tubes to continually compute the bomb release point during the bomb run (the USMC AN/TPQ-10 directed aircraft to a predetermined release point). Planning for the USAF vacuum-tube trajectory computer/radar system began in early 1965 and in October 1965, F-100s tested the AN/MSQ-77 at Matagorda Island General Bombing and Gunnery Range on the Texas Gulf Coast〔 (the Matagorda training unit was later moved to Bergstrom Air Force Base). In 1967 a helicopter-transportable variant of the AN/MSQ-77 in rigid shelters (AN/TSQ-81) was developed for Commando Club bombing of northern North Vietnam targets (Red River Delta), and in 1969 training for an additional transportable variant with tower-mounted antenna and digital computer (AN/TSQ-96) was being conducted at the Reeves Instrument Corporation in New York. "In March 1966 the first MSQ-77 arrived at Bien Hoa" Air Base ("activated" April 1 to use the "reverse MSQ method".)
