Brand spankin nooby can't find his own butt

Two questions.

First, when you resupply with empty tubes, you need to change to the torpedo loading screen and slide one of the torpedoes into a tube to "prime" the loading process, then click the resupply anchor icon again to get a full load of torpedoes.

Second question is more complicated. Ordinary engineering uses a design safety factor of 150%. What that means is if they want a car trailer that will carry a load of 1000 pounds, they design it so it will carry 1500 pounds before something breaks.

The pressure hull of a sub is the same way, but most are engineered beyond the 150% factor. The "test depth" is the depth that the builders guarantee, each sub is taken out by civilian workers and dived to the test depth before delivering the sub to the Navy. The design depth is deeper than that, the crush depth is estimated since you obviously can't test it in real life since nobody can come back and tell you what it was. Most WWII subs were designed with a safety factor of 200% or more, if the specified design depth was 300 feet the engineers would design something they were sure would survive to at least 600 feet.

In game it's different from real life since the programmers didn't really understand what they were doing, plus it had to be translated into English and some terms were translated wrong. "Crash depth" for example is used for both the depth at which the sub will level off if a "crash dive" is ordered, and also used for crush depth in a different file.

The red needle on the gauge is different depending on if you have the shallow or deep gauge selected, for the shallow gauge it's periscope depth, for the deep one it's "MaxDepth" as defined in the CFG file for the sub. The actual crush depth (mis translated as "crash depth") is in the ZON file for the sub, much deeper than the needle. Stock game GATO for example, MaxDepth (red needle) is 100 meters, crush depth is 190 meters. There's also a "crash speed" in the ZON file, that defines how many "hit points" the sub loses per second when below crush depth.

Then there's the damage factor - if you look at the damage control screen in the upper left corner there's a "hull damage" percentage, if it's anything other than 0% then the crush depth will be shallower than the default. For example if the hull damage says 20%, you'll start taking crush damage at 150 meters instead of 190. And of course as the "hit points" accumulate the hull damage percentage will increase and the crush depth will decrease, so you're between the devil and the deep blue sea if there are destroyers overhead.
