Topic review - Calling all Russian submarine fans

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.

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:

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

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).

"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".

"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.

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.

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

I hope we get more 3D printed screws, especially badly needed in 1/700 scale. 688, Oscar, Typhoon, Seawolf SSN575, Papa, Victor... etc. Its so easy to upgrade an existing model with one also, which should have good longevity of this product, I hope. Just charge what covers your cost+margin and Ill buy it.

MOSCOW, June 11. /TASS/. The improved Project 955A (Borei-A) strategic nuclear-powered missile-carrying submarine Knyaz Vladimir will enter service with the Russian Navy on June 12, Russia’s Defense Ministry reported on Thursday

Can someone release a 1/350 Plastic Model kit of her now please?!

Great Links. I had a many of those as separate photos. It's great having them all a couple of links though. I will of course download the whole bunch.

I do like those 3d printed props. I still have a few PE versions in brass for US and Russian Subs from YMW and Flagship stash. If these links show any disparity between my old PE, the kit models plastic "things" and the Prototype , I will do that eBay search for the 3D variety.

Thank You to everyone helping out on this PROPer thread.

Might need a "calling all Prop fans" thread...!

You could make some pretty good educated guesses on size by looking at these photos. I think most of us would be very happy to get a 3 dimensional printed screw (as opposed to flat photoetch). Frankly, your propellers above look pretty damn good!! As far as dimensions, try to get as close as the photos allow by measuring other items in the photos.
I doubt that the Russians or the US Navy are going to allow you to take exact measurements. When I used to visit submarines in Groton, the guards were armed....

Attached is a photo of an Ohio R/C submarine from Bob Martin. Again, I think the shape is of prime concern and the physical dimensions are "close enough".

On a somewhat related submarine topic, there is an excellent course on nuclear power engineering (https://mragheb.com/NPRE%20402%20ME%20405%20Nuclear%20Power%20Engineering/ ) with very extensive chapters on just about all things nuclear. Scroll down for the numerous PDF chapters available on the various topics.

Here is the link on the Marine Nuclear Propulsion chapter of the course: Extremely detailed in both engineering and nuclear reactions. https://mragheb.com/NPRE%20402%20ME%20405%20Nuclear%20Power%20Engineering/Nuclear%20Marine%20Propulsion.pdf
As close as you are going to get without enlisting and surviving the Naval Nuclear Propulsion Course (Rickover College of Nuclear Knowledge). There will be a quiz later...


Thanks Tom. Yes, I've poured over those links and then some. There at least one interesting Russian language forum that is useful as well. And armed with Google translate it is easy enough to navigate. Plus, a picture is worth 1000 words...and there are tons of them (well, lots, instead of 1 or 2 for US subs). I haven't found similar of US subs other than an occasional image here and there, collected into reddit (and the link above, have that one book marked) postings. The Russian forums often offer multiple images from multiple angles, subject to the photographer's skill of course (and camera quality), and you have to go digging deep into multi-hundreds of pages deep forums.

I don't know the exact diameter, but based on satellite photos and some Navy drawings I have, the diameter is about 19.2 feet. Also, I've since found out that the 688 propeller is 18'0".

Really nice work. I will pass around your pics/Post. Many of us want proper Props.

Thanks for the update.

I've released my Oscar II and Delta IV screws on eBay for those interested. Not being an expert on either (or, well, anything for that matter submarine-wise, babe in the woods compared to some of you guys!), they are what they are. I am willing to correct if deemed outrageously wrong. But part of it is a balancing act, getting the look right. You have to balance how the screw mates to kit hull, with that diameter driving the size of the screw boss vs. what you can find regarding the overall diameter of the screw, all subject to finding hard numbers for any of it.

The Ohio screw diameter is based off dimensions acquired from Russian sources. These were the ONLY numbers I found anywhere, and frankly the satellite photo indicated to me it is enormous and decidedly much larger than ever portrayed. Is it too big? I honestly don't know. But it's again, decidedly better portrayed than what comes with the DML/Dragon kit.

Nice work on modeling those propellers! Looking at these photos, the shape looks good but they look a bit large (perhaps it's the perspective of the photos). The Ohio should have a propeller diameter of about 19.2 feet and the 688 a diameter of about 17.8 feet.
