OTOH, after three career years of diving at every air contact, the boat became an ace in a day after sufficient annoyance, so maybe I've been missing out on radar too.

i am sure there is plenty of data available on IJN Radar Detection on the web. here is an example.

the use case here is that you are on the attack at close range. radar detection is not the real problem at the range you are attacking because your boat has probably been detected by surface radar. maybe. depends on a lot of variables but probably.

you can either use radar to help you locate enemy vessels at close range or rely on visual detection or stay submerged and try for a sonar shot, which is tough with WWII technology. keep in mind that you still not be able to lock on to a target using either technology...only visual contact will enable you to lock onto a target to fire a torpedo. at the range you are attacking, do you need target lock? use the info you have and attack. you will have to develop your skill at attacking without target lock. it will take practice and you will miss with torpedos but that is the cost of experience. just don't get run over by an AK or CA. it can ruin your whole day.

good luck.
