{{Short description|Type of aircraft radar}}
'''AN/APQ-13''' radars were a ground scanning radar developed by Bell, Western Electric, and MIT as an improved model of the airborne [[H2X radar]]. They were used on [[B-29]]'s during [[World War II]] in the [[Pacific war|Pacific theater]] 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 [[radome]] was carried on the aircraft belly between the bomb bays and was partially retractable on early models. The radar operated at a frequency of 9375 ± 45 megahertz and used a [[superheterodyne receiver]].

== Weather radar use ==
The AN/AQPAPQ-13 radar was the first military radar converted to civilian use as a weather warning radar. About 30 systems were converted, starting in late [[1945]]. They were installed in the aircraft at military bases.<ref name="HEM">Historical Electronics Museum [http://www.hem-usanationalelectronicsmuseum.org/past-gallery.shtml <http://www.hem-usanationalelectronicsmuseum.org/past-gallery.shtml>] {{Webarchive|url=https://web.archive.org/web/20120128121138/http://www.nationalelectronicsmuseum.org/past-gallery.shtml |date=28 January 2012 }}.</ref>
 
The last operational APQ-13 was removed from the [[Fort Sill|Fort Sill, Oklahoma]] post weather station in October 1977 for display at what is now the [[National Museum of the United States Air Force]]. The museum intended to display it in its original configuration as a navigation and bombing radar, but would note the radar's much longer history as an operational weather radar.<ref name="amsrad">Roger C.
