You'll need to do 3D models that follow the way the models in Game are done.
Low poly, seperate parts.
You'll need to do the internal stuff as well for them.
Then the cfg file stuff.
As well as the Flotilla stuff.
Biggest problem?
They used external torps.
The Game only renders the torps when fired.
Fireing them is easy.
Makeing the external torps on the subs vanish is not as easy.
Unless you REALLY know how things work.
