More holes means more drainage! The superstructure is nothing but pipes, tanks, escape trucks and sail struture welded to the hull. It is a maze of steel, valves, wire. Water gets into the super structure and needs to exit the superstructure. More holes and you get this done quickly both ways.
Nisgeis asked me to take some pictures of the superstructure on the Torsk. I did so this weekend. I will post these pictures as soon as I can. I got pictures of the torpedo tube flasks for compressed air, the hydraulic motor/gear for the dive planes and the trunk of the escape hatch. You will see the reason for the drainage holes because the superstructure is really a large void that takes on water as the sub submerges.
