Was radar difficult to retrofit to older Royal Navy warships, and did the Navy distrust it?
Short answerRetrofitting was challenging, but radar had been developed through the 1930s and was not viewed merely as an unproven wartime experiment.
NotesFitting complex equipment into older hulls brought practical challenges in power, cabling, antenna placement, and integration. Radar had nevertheless been tested at sea through much of the 1930s before wartime refits accelerated. Officers were therefore familiar with the technology rather than being asked to accept an unknown invention on faith. The practical questions concerned which set was available, how it could be installed, and how the ship would use its information.
