Why would the USA or Isreal care. That think looks almost WW2 vintage.
Probably sprung a leak and sunk.
Well, them there old-fashioned German WWII “short range diesel boats” ended up sinking quite a few US ships sailing ....... right offshore of Galveston carrying Houston ship channel oil.
Seems its not too much of a stretch to see them shooting a couple of modern (Russian/Chinese/NK/Cuban/ex-Ukrainian) modern self-guiding high-speed torpedoes at a few US escorts and tankers a few miles off of the coast of Iran.
To stop a tanker with only one propeller attached to a very large, very noisy direct drive diesel engine that is VERY NOISY all you have to is push a button. To sink a US escort that can’t use sonar because of a VERY NOISY tanker close aboard all you need is two torpedoes. And one button.
