Pretending to be a whale doesn't seem like a sound principle to me. Subs don't follow the migratory paths of whales, as far as I know. Now, we just look for whales that are out of place and send a drone out to check.

Maybe you're right though, that overwhelming the signal pattern, similar to how SDI/Star Wars was deemed moot.

Reminds me of that old joke about then-modern stealth fighters having the radar cross section of a bird, with a reply stating that if they saw a bird going at mach 0.8 they'd fire some missiles at it.

I have a vague memory that nobody knew how high some birds flew until military radar got good enough to see them.

They sent up an interceptor aircraft to check out what was flying up there, rather than missiles.
