The idea is based on the USS-Swordfish but totally fictional. It is ready for use with any sargo class submarine.
Credits go to Foofighter for his nice SargoBlackSkin which I used as base for this and for his allowance to use it

Credits also go to the developers of The Gimp and the one(s) who wrote the dds-plugin for it

.
The skin features:
- a swordfish's head and spear right at the boat's nose
- blue fore depth rudders
- an overall weathered/less clean look on the painting as well as the depth rudders for a more realistic appearance
- a stylized version of a swordfish as tower emblem
There's also a version which includes a bloody, fancy, coloured version of the tower emblem, see the screenshots to find out which one you like better

Also, as I recently learned (thanks, tei) that the texture files ending in ...02.dds are used automatically in the late war period, I decided to include the late _and_ black skin into one singe mod. So before mid '44 the game will use the black version and after that the light grey version of the skin. Think that makes sense.
And this applies also to the skin with the coloured emblem, of course.
