Get my bow damaged when I fire Mk37's
 

I get a report that the tube jammed while firing. And then there's a hole in my hull. Anybody else experience this ?

Because you fire torpedo at high speed !, move your sub at low speed before firing !:)

I think 20 kts is the speed where it jams when firing. Go 19 or less. If you are really moving and you need to slow down and fire quickly set engines all back full.

Yes
 

I was beginning to suspect that my speed might be the problem. Thanks.

This is a 'feature' of the game.


I have been trying to get the developers to change this for a year or so.


US submarine(s) can and do shoot torpedoes at flank speed without any issues..
The MK-37 MAY be an exception due to it being a swim-out weapon.

I found the occasional "Captain! Bow damaged!" when I fired a Mk37 at high speed, and/or when activating it immediately. At first I was a little perturbed but then I figured it's an operational thing, maybe it was arming and detonating from my ship's magnetic field (I know, the game may/may not be coded that way but I like to imagine), so I give the torp time to get clear of my sub before activating it. And I never launch over 10 knots, No problem after that.

If you look into the weapons.txt file, you'll see the launch threshold for each torpedo
