April 6th was the last update and I'm still being offered the SJ-I Improved Surface Search Radar.
I've also noticed some of these destroyers have got surface search radar, as a test I marked the subs position on the nav map when a Kisaragi turned towards us and then I submerged and moved away and waited. Sure enough that destroyer knew exactly where I had been, its a good job it was dark because I had an easy shot and I put two torpedoes up his ass.
