New Fast-Attack Nuclear Submarines to be Named Arizona and Oklahoma

[Wookie]

Just in case other readers are perplexed by this comment: The saying goes:

With new detection systems, the only submarines are diesel boats running submerged and nuke boats sitting still. If it’s moving, it’s making enough noise to be a target.

I've been browsing the U-Boat forums on this subject and it seems that U-65 collided with a sunken wreck in the Irish Sea on her first patrol. There's more stories that I have not gotten to yet.

Besides the fictional Red Storm Rising where the Victor class was using the wreck to hide its plant noise and confusing MAD equipment, there seems to be no known cold war era stuff that is public.

Don't give away anything you might want to use again, and they call it the silent service for a reason.

Theoretically speaking it wouldn't matter if the nuke boat was moving or not - with the exception of subs that have natural circulation reactors like the S8G units on the Ohios, if the plant is active there will be cooling pumps running. Of course, the big question might not be how sensitive your sonar is; it's how to filter out all the other noises in the water and how to deal with phenomena such as density layers.

Speaking of sub stories, I had a little fun recently trying to look up a summary of a French "documentary" on the Kursk sinking some kook mentioned on another forum. It made that crap video on the Thresher look semi-plausible by comparison; basically it tried to mishmash every "an American sub sank it" theory.

In the fictional tale, the Victor was using the wreck to hide its reactor signature as the "currents whistled through the wreck". Having dove on several dozen individual wrecks they've all been dead silent...

Unlike the Thresher, the crew was alive for a day or two and their government failed them. National Geographic made a lost subs documentary that is about the only thing on the Kursk that is palatable to watch.

Following salvage operations, analysts concluded that 23 sailors in the sixth through ninth compartments reached refuge in the small ninth compartment and survived for more than six hours. As oxygen ran low, crew members attempted to replace a potassium superoxide chemical oxygen cartridge, which accidentally fell into the oily sea water and exploded on contact. The resulting fire killed several crew members and triggered a flash fire that consumed the remaining oxygen, suffocating the remaining survivors.

So the spinning propeller makes no sound?

Obviously depth has input, as does thermo/haloclines, but a spinning prop makes a racket.

Well duh, just do this instead

Maybe. I know I can neither confirm nor deny.

Hmmm, that sounds like a yes.
