And from National Interest.org:
The Yasen class measures 390 feet long and displaces 13,800 tons. It has a crew of just ninety, far fewer than its American equivalents, suggesting a high level of automation is built into the submarine. In shape it resembles the earlier Akula class, but much longer behind the conning tower and a hump to accommodate vertical launch tubes. According to the authoritative Combat Fleets of the World, Severodvinsk has a OK-650KPM two-hundred-megawatt nuclear reactor, good for the life of the boat, which drives it to speeds of up to sixteen knots surfaced and thirty-one knots submerged. Other reports peg it slightly faster, at thirty-five knots. It can run quiet underwater at twenty knots.
Severodvinsk’s sensor suite consists of a Irtysh-Amfora sonar system, with a bow-mounted spherical sonar array, flank sonar arrays and a towed array for rearward detection. It has a MRK-50 Albatross (Snoop Pair) navigation/surface search radar and features a Rim Hat electronic support/countermeasures measures suite.
Armament for the submarines consists of four standard-diameter 5,333-millimeter torpedo tubes and four 650-millimeter torpedo tubes. The torpedo tubes can accommodate homing torpedoes and 3M54 Klub missiles, which are available in both antiship, land attack and antisubmarine versions. For even more firepower, the Yasen boats are each equipped with twenty-four vertical launch missile tubes behind the conning tower, each capable of carrying P-800 Oniks ramjet-powered supersonic antiship missiles.
From the same source, before we get the usual scoffing idiots:
In October 2014, one of the U.S. Navy’s top submarine officers, Rear Admiral Dave Johnson, the Naval Sea Systems Command’s program executive officer (PEO) for submarines, said “We’ll be facing tough potential opponents. One only has to look at the Severodvinsk, Russia’s version of a nuclear guided missile submarine (SSGN). I am so impressed with this ship that I had Carderock build a model from unclassified data.”
According to 60 Minutes, unnamed Pentagon officials claimed that Severodvinsk “slipped into the Atlantic Ocean and for weeks evaded all of the attempts to find her” in the summer 2018.

Russia actually has had heavily automated (as in crew-requirement-reducing machinery, not as in unmanned operation) subs out for several decades, with the first widespread example being the Alfa class boats, which don’t seem to have had many show-stopping problems with their automation. The US, not so much.
And the Yasen-Ms are even quieter than the Yasen-class Severodvinsk. Something to think about.
