well, i'm not talking about functioning in space, but rather would it survive. space ships are designed to hold everything together, retaining positive pressure inside, hence designed to "pull in". a submarine, on the other hand is designed to withstand pressure from outside, hence technically designed to "push out".

now, if u take a submarine and instantaneously put it in space, wouldnt its structural integrity fail?

(doesnt matter about propeller functions, ballast tanks or whatever)
and yes, yellowsubmarine can go anywhere
