I hate to be the bubble popper here but there are no submarines in the desert well at least not in real life.
it is a training facility where they teach everyone how to run the equipment on the submarines. they have
mockups of all the control rooms. there was a pre-existing base at the location so instead of paying exhorbitant rent somewhere else they built in the desert. Easier to protect all their super secret tech. if they can see you coming a mile away.

A good place to hide cylinder UFOs and rods if anyone cares.
Just hearsay that a submarine was wired for the first levitation and
flight experiments by von Braun.
With heavy lifting transports the sub might be lifted out of Nevada to
the Pacific. Well a super advanced lifter.
Perhaps a new engine is being worked on and not weapons.

Not to imply that you are wrong but I am just wondering how you know this? Do you work there or know someone ?

Its sensible to locate in the desert for points already mentioned, however there is additional reasons; the Navy also maintains its own space based weapon and spy program. It is perfect location to carry out testing and research programs.

The other point is the quantity of Nuclear Blasts carried out in Nevada over the years would have carved massive holes in the crust, at one time Russia was using nuclear weaponry as a tool to create caverns for various purposes. Any type of ground penetrating mapping would reveal large caverns and who knows what else as result of the testing over the years.
