Difference was in material and quanity used.

The material difference was balao's (and tench's) High tensile steel. On top of that, the steel plating used was thicker.

Gato and boats preceeding it used a softer steel. Not high tensile steel, and the quanity used was slightly less in thickness.

Thus the nickname of "thick skinned" and "thin skinned" boats.

edit: And i had the part about the thickness of the steel increasing wrong. It was all in the material used.

The USS Pike was the first all welded construction according to what i have read. I think the others may have been partial welded construction. Check the second paragraph in this link.

Hmmm I thought all the Porpoise class were riveted.Currently reading the book "Luck of the Draw" by Captain C. Kenneth Ruiz(Ret) again.Ruiz was aboard the Pollack, he mentions the sub was riveted. Although they were once forced to 500 feet during an out of control dive, rivets and things were popping out and shooting everywhere.

I'm thinking it was based on which shipyard built the boat. I have also read that the USS Shark SS-174 was of all welded construction and i believe the Tarpon was also, which was one of the reasons these two boats were often considered Shark Class instead of Porpoise. I have looked at a couple dive videos of the USS Tarpon and i can't really say for sure one way or the other.

Its actually kind of confusing since some sources claim the USS Shark was the first all welded construction.

Early war torpedoes ran deep, so set them for shallow runs.

A small tip, Floven.

Under NO circumstances should you go below 700 feet in a Balao. It will only spell your doom. This is because it takes a while to finally level out, and by that time you're probably at 800-something.... Balao boats, in TMO (1.9 anyway, not sure about 1.76...), will go to crap at 8-0-3 feet on the dot!

Also, for the Gato, 550 should be the max depth you want to consider. At precisely 597 is when you take a permenant trip to Davy Jones' Locker.

As for the older subs, excluding to S-Boat, you can go 200 feet below test depth (i.e, 250 = max 450).

As for the S-Boat, well.... don't go below 300, trust me.

Good Hunting, and good luck in your patrols!

I've been to 815 feet in a Balao once...didnt implode, think it was TMO 1.6 or 1.7, was a while back.
