I was about to note that that new sub looks familiar. I wonder how well the Magneto-hydrodynamic drive is working on that sub.
I’m pretty sure the MHD is not in service on that one but that 33,000 horsepower high speed, shrouded screw, is ready to crank as soon as it clears that bridge. The Virginia class boats hide the screw inside a tubular shroud which helps with flow as well as sound suppression.
Also, a real submarine story, as told to yours truly from a co-worker that served on the Archerfish (SSN-678). They spent a great deal of time in the North Atlantic and at one point found themselves somewhere in the Barents Sea area, not too far from the coast of Russia.
One night, my friend was in his ‘rack’, presumably asleep when the Archerfish did an abrupt steep dive (or did they surface, I do not remember that detail) and someone got on the intercom and shouted “Torpedo in the water!!!”
Apparently, the Russians noted their presence and took the liberty of launching a torpedo (probably not armed, just something to get a reaction. Part of the ongoing war games that the 2 nations have played for decades).
Anyway, after my friend explained the cramped quarters in the bunk, and how difficult it was to get out of there when you were pitched at some crazy angle (30 degrees, maybe), I gained a new appreciation for our submariners.
I worked with a couple of other sub guys, and on my last team at work, we had a guy that had worked on a carrier (he used to ask other Navy guys, were you on a sub or a target?). Navy nukes seem to flock to the electric power industry.
