I publish on subs, other military/naval, nuclear weapons & political issues. Aussie sub changes are slow: talk since 2009 rather than actual new subs. The Collins LOTE 2028-2040 might help Australia's sub availability temporarily. UUVs help. POTUS 2031 may cancel AUKUS Virginia offer due to USN advice it needs all its SSNs through to the 2040s to face China & Russia. US has sacrificed Virginia production pace in favour of Columbia SSBN production. Shawn C is an excellent contributor.

Russia's Improved Kilo II Submarine (Project 636.3)
Russia's original (Project 877) Kilo subs have been operating since 1980.
But the newest sub-class is the Improved Kilo II, Project 636.3. The Improved Kilo II first entered service in 2013 and is being supplied to the Russian Navy only.
The indomitable "Jive Turkey" presents a clear, well-paced, Youtube description of Improved Kilo II Project 636.6 at https://youtu.be/OIpILOFfnYMand below
Highlights of this August 2019 Youtube (usefully seen in conjunction with this list) include:
1:43 - First of class, B-261, was laid down in 2010 in St Petersburg
4:42 - list of weapons carried
5:27 - Russians are clever in the way they load torpedoes from outside through 2 torpedo tubes in the bow
6:02 - uses an advanced (for Russia) Lama-EKM combat system
7:10 - Rubicon-M Sonar System with details (search for Rubicon-M in this very comprehensive article here)
8:15 - speed, test depth, noise "117 DB AT 1/YARD" ("Jive" doesn't reveal how decibels (DB) were determined from 1 yard of B-261)
