Editing Courageous-class aircraft carrier (section)

=== Fire control and radar ===
To assist its weapon systems in hitting their target, ''Furious'' was completed with one [[fire-control system]] for each side, with separate [[Fire-control system#Naval fire control|directors]] for low-angle and high-angle guns. The 5.5-inch guns were centrally controlled by a [[Frederic Charles Dreyer#Dreyer Fire Control Table|Dreyer Fire-Control Table]] on the lower deck while the 4-inch guns had their mechanical computers next to their directors.<ref name=f5 /> The existing fire-control directors were removed when ''Furious'' received her new dual-purpose 4-inch mountings in 1939. New high-angle directors, including two for the ''pom-poms'', were mounted on top of the new island and on the former lower flight deck. Over the course of the war [[Type 285 radar|Type 285]] gunnery [[radar]]s were mounted on top of the high-angle directors. She also received a [[List of World War II British naval radar#Type 290|Type 290]] air-search radar.<ref name=f9 />

''Courageous'' was initially fitted only with low-angle directors for her guns, but these were replaced by dual-purpose directors when she was refitted in 1930. (''Glorious'', completed later, had hers from the beginning.) Neither ship was fitted with radar before its early loss.<ref>Burt 2012, pp. 285–286</ref>
