The H2X radar, nicknamed the "Mickey set", provided a ground mapping capability for both navigation and in daylight when overcast (and at night) for the USAAF during World War II. USAAF recruitment poster. ... World War II was a truly global conflict with many facets: immense human sacrifice, fierce indoctrinations, and the use of new, extremely devastating weapons—the atom bomb being the ultimate. ...

The H2X system replaced the British H2S radar. It used a shorter wavelength that gave a sharper picture. The U.S. converted fifty B-24 Bombers into Pathfinder Aircraft equipped with the H2X radars. The radar dish replaced the ball turret of the Pathfinders. The "Mickey set" was installed in the radio room and navigational and bombing information was given to the Navigator and Bombardier. These aircraft recorded 1132 sorties during World War II. The H2X in production was called the AN/APS-15 and was a three-centimeter radar. It was designed to see through clouds for bombing as well as a navigation aid. In Europe several P-38 fighters were also converted to carrying H2X radar in the nose, along with an operator/navigator to obtain radar maps of German targets. The H2S radar was used in bombers of RAF Bomber Command, it was designed to identify targets on the ground for night and all weather bombing. ...

In the Pacific theater, B-29’s were equipped with the improved H2X radar called the AN/APQ-13, a ground scanning radar developed by Bell, Western Electric, and MIT. The radome was carried on the aircraft belly between the bomb bays and was partially retractable. The radar operated at a frequency of 9375 ± 45 megahertz and used a superheterodyne receiver. The radar was used for high altitude area bombing, search and navigation. Computation for bombing could be performed by an impact predictor. A range unit permitted a high degree of accuracy in locating beacons. The Pacific War, which is known in Japan as the Greater East Asia War and in China as the War of Resistance against Japanese Aggression (kang-Ri zhanzheng, literally Resist Japan War), occurred in the Pacific Ocean, its islands, and in Asia. ... The Superheterodyne receiver (or to give it its full name, The Supersonic Heterodyne Receiver – usually these days shortened to superhet) was invented by Edwin Armstrong in 1918. ...

After the war, late 1945, the APQ-13 became the first military radar converted to a domestic peacetime application as a storm warning radar. About thirty systems were converted and installed on military bases. It was replaced by the CPS-9 system in 1949.
