Keltos,
I am not disputing your data only your conclusions as it applies to the stock game. Now there are a lot of Damage Models around that change some data. But as it applies to the stock info:
In your post you are stating distances for "Hull Breach" and "out of commission", I am talking doing damage. Even thought the Max range is 40 meters it does not do 100% of it's damage at 40 meters. I have never had a hull breach at 40 meters. Also the game uses hitpoints so it is totally different than RL.
At 40 meters you may get a .03 damage to a component on the sub, you are not going to get a "hull breach" only minor damage if any at all.
You also state "the attacking ship needed to be moving above a certain speed or it would be damaged by the force of its own weapons." Now I realize the hull of a submarine is built to withstand more "pressure" than the bottom of a DD but that DC is not exploding at 10 meters.
To put it is perspective, your subs are 100 meters long, so if a DC went off at the nose you wouldn't feel it in the conning tower (50 meters away)?
I am NOT saying hull breach only that you would feel it and the effect could cause things to break at 40 meters in my opinion.
Put on your diving gear and we will put you 40 meters away and drop a DC, see if you get a headache.
So basically all I am saying in that the data is giving distances for "hull breach" and "disabled", I am talking damage. The article you quote is talking sinking a sub, not damage to components that gets fixed by the men on board.
