Changing torpedo firing depth

[VONHARRIS]

According to http://www.uboataces.com/uboat-type-xxi.shtml

" Equipped with a sophisticated echo chamber, which could identify, track and target multiple vessels, the Type XXI could fire blind from up a depth of 160 feet. "

After several tries to find the correct entry to edit , I am in need of help.

1. How can I change the torpedo firing depth for the XXI only?

2. How can I remove the 20mm guns , so that the XXI would look as a modern submarine?

Thank you in advance.

1) should be simple:
data\Submarine\NSS_Uboat21\NSS_Uboat21.cfg\[Properties]\TorpLaunchMaxDepth
2) comlex way:
a) extract & edit 3d model of the turm + its shadow + its reflection
2) delete all corresponding entries (nodes, lines, values) from files in data\Submarine\NSS_Uboat21
3) delete/edit all files in data\Cfg & data\Menu folders...
simple way:
edit basic.cfg\[SUBMARINE_AMMO10]
set A01_00=-1 & A02_00=-1 for every year
