For the WWII folks, Zvezda has announced a 1/144 Shchuka class sub for this coming year:

It's in Russian, so non-Russians will have to make-do with turning on auto-translated subtitles, but an interesting little documentary courtesy of Russian State TV with some onboard views of the fitting out of the first Borei-A Class Ballistic Missile Submarine Knyaz Vladimir or Prince Vladimir:

Great video!
And that is a pretty funny name, ironic or historical, or both? Russian Navy humour?

I gather it is named after Vladimir the Great from medieval times:

https://www.bbc.com/news/world-europe-33689641

'Russians celebrate Prince Vladimir the Great as the man who converted their country to Christianity'

So he is a significant historical figure in Russia it seems.

"Three Russian nuclear submarines surface from under Arctic ice simultaneously for the first time in the history of Russia as a part of the Umka-21 Arctic expedition".

https://www.youtube.com/watch?v=n4SOXOE44ms

https://www.rt.com/russia/519310-nuclear-submarines-emerge-ice/

"The stunt took place near Alexandra Land, a large island and the site of the Nagurskoye military base, around 3,000km north of Moscow."

Looks like three Delta IV Classes. No pennant numbers or coats of arms visible, so not possible to identify which three. The article doesn't specify either.

It's one standard Delta IV, one Borey-A (there's only one, so Knyaz Vladimir), and the special ops Delta-IV BS-64 (has same sail as Delta IV, but lacks the missile hump, so the ice doesn't rise as high on the aft end of the sail).

Indeed you are correct Timmy. I should have looked more closely!

Interesting little documentary about the Northern Fleet's Akula Class attack submarines or 'Project 971 Shchuka-B' in Russian parlance. It's in English too which helps:

For those interested in the Russian efforts in employing liquid metal (lead bismuth) in their submarine reactors here is a link to an interesting technical paper from the year 2000. There is also a paper on the US liquid metal reactor effort in the second nuclear submarine, SSN 575, Seawolf.

While liquid metals (sodium of SSN 575 Seawolf, lead bismuth of the Project 705 Alfa’s) offer advantages in higher operating temperatures and at the same time, lower operating pressures than pressurized water reactors (PWRs) they also bring another set of difficult technical challenges, described in these reports.
