Two things you could always tell about a Russian nuke sub - where its reactor compartment was (evinced by the peeling paint on the hull surrounding it), and where it was (evinced by the noise they generated underwater).

with other word Moscow (Nigeria with snow) failed again to build a stealth/AIP - submarine ))

Did you read the article?

Such was the thinking behind the Soviet’s Project 661 submarine Anchar that was conceived in 1959: a speedy submarine that could race forth to intercept American carrier task forces cruising at 33 knots, blast them with long-range cruise missiles fired from underwater, and then get the hell out of Dodge.

It wasn't designed for stealth.

It’s a nuclear powered sub. All nuclear subs are AIP.

AIP doesn’t mean “silent”. It means “air independent propulsion”. All nuclear submarines are by definition AIP.

It was designed to be fast not silent. In the 1950s.

And RUSSIA defeated the Horde.

Moscow Horde = Stupid Talk.

That you can get a submarine to go that fast underwater is indeed impressive - technology-wise.

However - and this a HUGE however - when travelling at such speeds underwater with virtually no ability whatsoever to hear (i.e. "see") anything around you, it's like speeding through dense fog on the freeway.

And another issue with such speed can be mechanical failure - e.g. of fairwater, bow, or stern planes. If you're going to go that fast, you have to be able to recover from a jammed plane without exceeding your design depth. The faster you go, the shallower you must be or...

They likely used tech similar to super cavitating torpedos, where an air bubble is used to reduce drag. Thhose torpedos have been in use since the soviet union still existed, but those torpedos could hit 200 knots in speed, I imagine they just played around with the tech on a larger scale to try and get a sub to perform similar in ratio to size and weight.
