June, 1942 I detect a single Japanese merchant that is 8nm away, as I begin to maneuver towards him to with plans to submerge at 5nm I suddenly come under accurate fire *way* out of range for a simple Japanese merchant with a deck gun. In face while surfaced I decided to raise my periscope just to see if I could see the merchant and I could not.
So here we have a scenario where a US warship cannot spot and shoot at a simple merchant, but it can spot a submarine and shoot it accurately from 8nm away. Once I realized how ridiculous that was I decided to put a crew on the deck gun to see if they could see them and shoot back.. Nope. A bit overpowered when a merchant can out detect, and outgun a U.S. Warship on full alert during a wartime patrol.
In SH3 GWX and SH5 you can regularly submerge at 5nm away from merchants and 6-8nm away from enemy warships to sneak up on them at that point.
Is this an overzealous Sim.cfg setting I can tune down, or is this a setting somewhere else? Senors.sim?
