After an extensive underwater search utilizing the bathyscaph Trieste, oceanographic ship Mizar, and other ships, Thresher's shattered remains were located on the sea floor, some 8400 feet below the surface. Deep sea photography, recovered artifacts and an evaluation of her design and operations permitted a Court of Inquiry to determine that she had probably sunk due to a piping failure, subsequent loss of power and inability to blow ballast tanks rapidly enough to avoid sinking. Over the next several years, a massive program was undertaken to correct design and construction problems on the Navy's existing nuclear submarines, and on those under construction and in planning. Following completion of this "SubSafe" effort, the Navy has suffered no further losses of the kind that so tragically ended Thresher's brief service career.
After the sub sank, the Navy investigated and determined that the most probable cause of the accident was a leak in its engine room because of corrosions in its pipes. This, in turn, could have caused electrical problems on the sub.
After the accident, the Navy established additional safety procedures, including the SUBSAFE program, which requires each submarine to pass a series of safety tests.

There was a story in there about one of our nuclear submarines getting lost in there as well, I dont recall the name of the sub but it was claimed that it was one that went missing back in the 60's or 70's but the public was told that it had sunk.

In my opinion one or both were lost in the sea under California and Nevada either due to disorientation or hostile action.
I'm not privy to what goes on at NUWC Hawthorne, but I find it likely that the facility has much more to do with research and testing of underwater ordnance than servicing underground caverns.

it's suspected that several WWII submarines were lost when the torpedo came back around on them and impacted the hull.

I have to say that I found your statement "servicing underground caverns" fatuous, insulting and unnecessary.

Is there a possibility that the Navy does operate submarines from Monterey Bay via an underground sea which extends underneath the San Joaquin Valley, then under the Sierra Nevada mountain range to a Naval Undersea Warfare Center deep below the Nevada desert in Hawthorne Nevada?

I heard time and time again about the sub facility on that lake from NAVY folks, so the idea they do something with subs on that lake is true. Fact, no doubt about it.
You know, it's really much easier to lose submarines the old-fashioned way.
The main problem with theories like these is is that they require thousands of people to be in on it and never tell a soul.
Having spent a good chunk of my life working with submarine support people (bear in mind we're not just talking about sailors, but civilian contractors and their employees and connections as well), I can assure you they're just not that tight-lipped (especially when drinking). :shk:
That certainly doesn't mean there isn't an extensive network of underground caverns under the western U.S., nor that the Navy or some other organization hasn't explored them or used them for some purpose.
But the idea that the Thresher or Scorpion were somehow lost in them strains credibility -- though I can agree that if you sent one of those submarines into such underground caverns, that's exactly what you could expect to happen.
If anything, I suspect we're talking about the USS Red Herring here.

Tens of thousands of Navy personnel have ridden the tubes and I haven't heard one single leak about that mode of transportation and its been what? 50 years? 40 years anyway.
. Any questions?
