Our submarines do use 2 hulls

[mylife]

we call the inner pressure hull the “people tank”

[myknowledge]

Which ones?

I meant double-hulled subs designed along the lines of the Akula, Typhoon and the latest Borei class.

I love all of these Navy threads. Brings me back, ya know?

I think the confusion is that the Russians make subs with two pressure hulls, AND an outer hull. We make ours with one pressure hull and one outer hull.
