After looking over my old notes from Subsim.com Ezboard (circa July 2001), I've decided to look into this topic of American and IJN radar capabilities in SH1. While the radars of the American submarines in SH1 is well documented, next to nothing exists about the Japanese radar capabilities. Anecdotal evidence exists. I think a lot of people here could relate an experience when they were attacked by IJN ships in conditions where only radar could've spotted the submarine. I'd like to dig into it in greater detail and tabulate what I learn so I can share the results with everyone here.
