Enemy Subs
 

I was roaming around Japan checking out the ports and I found one with a sub at the dock (I have seen a few others but ignored them).

Since I had never sunk one I thought I would just for the fun of it. I put two torps into her and she just sat there. Then I put another one into her and nothing. Annoyed at wasting torps on this I let go one more. Nothing. The torps were set at 7 feet and it is mid 44, I can't imagine they went under her and the reported impact was the dock.

Really pissed off so I surfaced and hit her about 8-10 times with the deck gun. Bright flashes on the hits.

By then a subchaser with a gun started zeroing in on me and there were 3 Destroyers coming so I went to periscope depth and slunk away with my tail between my legs.

I looked back at her and she wasn't even smoking.

Are they hard to sink?

Do you have any mods?
I think the stock game has enemy subs in port, but they're just decoration. They don't act like a ship in the game.

They will sink, but the expenditure of precious torpedoes is not worth the effort. It takes between five and eight to do the job. Not very satisfying. :/\\!!
