How much weight and space did 1950s radar add to warships?
Short answerEnough supporting power and accommodation were needed that Daring-class destroyers lost both torpedo sections.
NotesBefore-and-after Daring-class plans show that electronics impose costs far beyond the antenna's weight. Radar requires electrical generation, operators, maintenance access, and accommodation for the people who support it. Those systems consume internal volume as well as topside weight and power. In the Daring example, the completed radar fit displaced both torpedo sections, making the lost weapons a visible measure of the electronic installation's true design cost.
