AN/MPQ-14

The AN/MPQ-14 was a height and direction-finding radar which was used for Ground Directed Bombing (GDB), during the Korean and Vietnam War. The AN/MPQ-14 was employed to guide attack aircraft at night or during adverse weather conditions. It was the first guiding radar system used to direct bombing missions conducted by the US Marine Corps, introducing the ability to deliver ordnance in close air support missions in poor visibility conditions. The AN/MPQ-14 operated in the frequency range of 2,740 to 2,960 MHz and had an azimuth of 360º.
