Latest revision as of 16:47, 29 August 2018

The AN/MPQ-2 Close Cooperation Control Unit was a truck-mounted post-World War II automatic tracking radar/computer/communication system ("Q" system) for aircraft command guidance, e.g., missile tracking, and for Radar Bomb Scoring. For ground directed bombing (GDB), an operator would manually plot a target on the "Blind Bombing Plotting Sheet", then use the manual "E6B computer and bombing tables" to plot the release point for striking the target, after which a radar operator used the MPQ to acquire a track of the bomber near an initial point during which allowed ground control of the bomb run to the release point.

Based on the World War II SCR-584 radar developed by MIT and which was used for the "SCR-584-M missile control Receiver and beacon", the MPQ-2 included an "Reeves Instrument Corporation RC-294 Plotter" and its analog computer for converting radar range, azimuth, and elevation to cartesian coordinates, as well as a plotting board for drawing the aircraft track. The AN/MPQ-2 was the basis for the Rome Air Development Center's AN~MSQ-1 & -2 Close Support Control Sets also used in the Korea and the MSQ-1A was used for command guidance of the Matador missile.

Locations

Radar Bomb Scoring detachments of the Colorado Springs Tent Camp|Colorado Springs' 206th Army Air Force Base Unit]] (organized on June 6, 1945) used MPQ-2s at Kansas City, and Fort Worth Army Airfield, and in 1946, the List of V-2 test launches Launches of captured V-2 rockets in the USA after 1945 4th launch of a V-2 at White Sands Proving Ground (1946) was tracked by two MPQ-2s. In addition to the CONUS RBS detachments (e.g., Detachments C, K, & N), Detachment 23's AN/MPQ-2 was at the South Ruislip Heston Radar Bomb Scoring Site on November 10, 1950, and after deployment to the Korean War, the three AN/MPQ-2 radars of the 3903rd Radar Bomb Scoring Group RBS detachments were transferred in January 1951 under the operational control of the 502nd Tactical Control Group (TCG). The MPQ-2 guided Martin B-26 Marauders against enemy positions in front of the 25th Infantry Division.", and On February 23, 1951, the 1st Boeing B-29 Superfortress mission controlled by an MPQ-2 was flown,
