I use GW 2.1 too , (only had a couple of crashes when saving or loading some saves with GWX 2.1 which i would really like to solve , my version is freshly installed with no mods , but otherwise it's really great expansion ) , i had the same interrogations about warships , i was wondering where i could find some other than at Scapa Flow , until i encountered a Bogue Class aircraft carrier yesterday in the Atlantic , toward December 1942 , escorted by 4 destroyers , i could sink him because i was extremely lucky , making a sort of kamikaze attack in rough sea despite a destroyer pinging me , and sunk the a/c carrier with only one electrical magnetic torpedo exploding just next to his "propeller" and fired at less than 400 meters from him , was really a lucky shot made hastily , it took lots of time for him to sink ,his escort DD were crazy about me and almost got me with DC before he finally sunk and i got the confirmation message .
I have to say nothing is more satisfying than sinking a war ship , i'm kinda feeling bad when i sink civilian ships thinking about the poor dozens guys who drown , whereas a warship , it's kinda different since the military personel on board knows the risks and wouldn't hesitate to kill me . I'd also like to know appox where i can find some , so if anyone can give us some hints , it would be really kind
One thing i'd like to know too , as i re-installed SH3+GW2.1 just a few days ago after more than a year not playing , is if there is "life" in the pacific Ocean with Japanese and American warships etc.. just to know if it's worth going to the Pacific ocean in southern Asia as it takes time to sail there even in 2048 speed , cheers
