That privately-owned submarine sounds like something that would startle a US Navy attack sub off the coast of the United States, and since they wouldn't know what they're dealing with they might just decide to blast the crap out of you.

Yes they would. The Navy knows EVERY kind of sound under the sea. They know the sound of individual ships in addition to what type. Frankly, I wouldn't be surprised if some of the super-rich don't have private subs already.
