Editing Fire-control system (section)

===World War II aerial gunnery sights===
Simple systems, known as ''lead computing sights'' also made their appearance inside aircraft late in the war as [[gyro gunsight]]s. These devices used a [[gyroscope]] to measure turn rates, and moved the gunsight's aim-point to take this into account, with the aim point presented through a [[reflector sight]]. The only manual "input" to the sight was the target distance, which was typically handled by dialing in the size of the target's wing span at some known range. Small [[radar]] units were added in the post-war period to automate even this input, but it was some time before they were fast enough to make the pilots completely happy with them. The first implementation of a centralized fire control system in a production aircraft was on the [[B-29]].<ref>{{cite web |last1=Moore |first1=Christopher |title=Defending the Superbomber: The B-29's Central Fire Control System |url=http://airandspace.si.edu/stories/editorial/defending-superbomber-b-29s-central-fire-control-system |website=National Air and Space Museum |publisher=Smithsonian Institution |access-date=18 August 2020 |date=12 August 2020}}</ref>
