Hello from SFO, CA. I think SH5 is one of the better games once modded. There should be a SH6 that does the more modern submarine warfare; like the modern Diesel/Electric Subs and the Nuclear ones. I am into Civil Aviation in real life and have a penchant towards most simulators tilled to their most realistic settings.
On current SH5 patrol - Arctic Convoy - Distant Covers and I am totally sucking at it coz I am not able to spot even a single BB or a carrier. Actually I did sink a carrier earlier in the Arctic Convoy campaign but that didn't count towards my mission. And now I am just floating around like a moron looking for only those ships that'll count. I am bored sinking convoys already.
