Just hunt task forces. I was damn lucky and ran into one that had a fleet carrier, 2 DDs and a CL as an escort. DDs rushed at me and got nuked, no hits suffered. I took advantage of my watchmen ability to spot the ships and "ranged" the cruiser, resulting it sank by magazine explosion. After that the carrier was an easey peacey ^^
*Edit* Also, im now packing the modified files that allows you'r watchmen and you to lock on ships at maximum range of 15km (gunners fire that far now also)

Range increased up to 15km, visual also. Hostile ships will fire from ranges 13km and closer, depending on weather conditions.

Just Put it into Mods folder and start through JGSME. If you got issues, i'll see to them. And if you got some suggestions, i'll gladly take 'em into consideration.
O right, and i increased the ammunition on IJN 5" duals, maybe i putted too much (50000 shells or so instead of 240 ^^') but since you need to fire so many salvos to even hit a carrier from 14 km range that you're gonna need them.
