That’s inexplicable because spotting that submarine is completely trivial. They run on diesel if I’m not mistaken, even now. You could easily blanket the area below you with radar. They must have simply not been looking, probably because there wasn’t any threat at all of attack.

And that laissez-faire attitude towards operational security is what an adversary would count upon in a sneak-attack first strike scenario. Remember the USS Cole?

The Swedish sub that surprised a US carrier at a training exercise was indeed diesel-electric, which is a great advantage. When stealth is required, they can use only their electric engine, or even stop it all together if the enemy is very close and listening. With a nuclear sub, the reactor and its cooling are always there.

  I think the secret ingredient of "the Swedish submarine that sank an US aircraft carrier" is the Stirling engine: https://en.wikipedia.org/wiki/Gotland-class_submarine https://en.wikipedia.org/wiki/Gotland-class_submarine

    Ah indeed, forgot that tiny bit.

Blanket the area below, as well as detect incoming very fast and small RCS objects, furtive aircrafts, small surface vessels, all on high sea clutter... I feel people have a very inflated idea of the actual performance and capabilities of on-ship multimission radars.
