Wartime radar could be used for air or surface search, even when its performance in either role was limited. The example given contrasts radar fitted to Flower-class corvettes in 1940 with periscope-search tactics said to have become established in 1942. By 1944, submarine detection could dominate its use without explaining why the equipment had originally been installed. Reading a later mission back into the earlier fitting date therefore risks reversing the chronology. The exchange does not identify a particular radar set, so it cannot establish the development history of every Flower-class installation.

How later radar tactics can obscure the original purpose
Radar installation dates and later operating practices illustrate the danger of assigning equipment its final role throughout its service.
