I've upgraded my VII-A to a VII-D. We leave dock on out maiden voyage. I turn around to wave farewell to the cute nurses only to discover that there's two bloody big pipes coming out of my sub. One is the periscope, which is now set a lot higher than on my previous ride. What the heck is this other one? Are the grease monkeys in the dry docks pulling my leg?
Included is a nifty pic to highlight.
