Torpedo tubes.

08-22-10, 02:59 AM

In modern USN SSNs the torp room is not forward, but closer to amidship. The torpedoes must penetrate the pressure hull at less than the 10° angle at which they exit the ship. A greater than 0° pressure hull penetration would require an unwanted weakness in the form of an elipse in the pressure hull. Yet at some point the 10° angle is attained. In a 256” tube the obvious answer is that a larger tube inboard is represented to accommodate the torpedo, before and as it exists the boat.

Did any of that make sense?

Any thoughts? Or am I just giving up un needed info?

Consider it forgotten. Whatever it was.

forget what?

That doesn't really make sense to me. Perhaps a better context would make it more understandable.

Only if you want to be shot.

hanging is the usual method of execution.

But none of this is secret.

and what I know or have knowledge of, it is quite another.

Other than the shutters rotating as apposed to sliding you won't get anything else from me on this subject.

Positive control.

Explain how you would be violating OPSEC?
