The GE AN/MPQ-14 Course Directing Central was a Cold War radar/computer/communication system for ground-directed bombing (GDB) during the Korean War and was the 2nd GDB system used by the United States Marine Corps (cf. AN/TPQ-2). The combination ("Q") system provided command guidance for an aircraft to reach a predetermined release point for attacks in bad weather and nighttime, and Korea GDB operations included 900 flown by USMC Vought F4U Corsairs,[2] e.g., VMA-251 flying "...four MPQ flights for the 7th Marines in the early hours of 24 July,..." 1953.[3]

Production and deployment[edit]

The AN/MPQ-14 was created under a production contract[when?] to General Electric, and the central used the radar model from the AN/TPQ-2 Close Air Support System, a diesel generator set, AN/MRW-4 & -3 radios, and from the AN/MSQ-7 [sic]: the "guidance computer-transmitter set", data converter (spherical to rectangular computation), and "indicator-recorder" (plotting board).[1] "Housed and transported in two modified 3/4-ton trailers, two 2-1/2-ton trucks, one 3/4-ton 4x4 truck, and one mobile radar mount",[1] the USMC GDB team was ready for deployment to Korea in July 1951[4] after the USAF had begun Korean War GDB in 1950.[5] The AN/MPQ-14 was "moved into the" 1st Marine Division area[6] by the "First Marine Aircraft Wing"[4] near the 38th parallel north for guiding units such as the VMF-513 Corsair night-fighter squadron flying GDB from 15,000–20,000 feet.[citation needed] A variant of the central, the AN/MPQ-14A, had different radar and communication subsystems, and MPQ-14 was also produced by the "Advance"[7] and "Ultrasonic"[8] companies.

The AN/TPQ-10 Course Directing Central's[9] antenna dish (above) on a transportable mount is similar to the AN/MPQ-14 dish on a mobile radar mount.
