Smart beats big.
This is why we play war games with allies. I remember something about Israeli pilots mounting auto radar detectors in their jets to defeat US radar guided missile systems some years ago.
Never understood why we ignore diesel electric subs. Easier to maintain doesn’t mean better.
It was my understanding at the time that the Navy leased that sub, or a similar one, from Sweden, for testing. The U.S. Navy does not like diesel submarines because of their vulnerability when charging and limited time at sea. U.S. submarine missions involve long voyages far from home. Sweden is concerned with protecting their littoral. They do not intend to fight more than a few hundred kilometers from home.
Death from below!

The Americans never saw it coming… and never saw it leave…
Or , they heard it, tracked it, and coolly didn’t react and give away their capabilities...
I don’t remember that, but many attack subs are close to equal nowadays. What let’s me sleep at night is our Trident boomers. Every nation knows they’re out there, but no one knows where they are at any given time. They are the best held Top Secret in our arsenal. They could end any country if so ordered. God love our Submariners.
I hope the Navy has fixed this issue.

Nope. They have various excuses like: if it were real, there would be active pings and the sub would have been seen, but due to environmental regulations, they are not allowed to active ping because of the whales an such. So nothing to fix, just like the US Navy will not build electric boats like the Swedes, Germans and Russians to name a few.
Sunk by...
IIRC, the sub uses fuel cells to generate electricity and is ultra quiet as there is no steam flowing through pipes and valves and turbines to make noise.
Unless their first virtual torpedo volley was adjudicated undodgeable and sufficient to sink her I doubt the outcome. They’d certainly notice fish in the water, especially any that hit! And then their behavior would have changed.
What’s worse is that the sub was put together over a weekend using a kit from IKEA. They were guided by the guy who wrote the instruction manual.
Well, if the submarine hadn’t turned on its GPS transmitter, how were we supposed to detect it?
Almost certainly they have. Anything mechanical generates noise. Subs with AIP propulsion are incredibly quiet but not impossible to find, if you know what you’re looking for and where on the noise spectrum to look. The U.S. Navy learned a lot from these exercises, which is why they kept the sub around for so long.
