Municipal authorities in Sarov, Nizhny Novgorod Region, accidentally revealed the design for the latest Russian submarine when it posted an account of a meeting with its commander on its website. The high level of secrecy surrounding the submarine suggests that it is a unique experiment on the part of scientists and the military.


www.kommersant.com...

Here is where it gets interesting;

The theory was advanced on an Internet forum yesterday that experimental Project 20120 is to test unique technology – the installation of an atomic reactor on a diesel submarine as a backup energy source. Similar experiments were conducted in the USSR. In 1985, a B-68 diesel submarine was equipped with a supplemental VAU-6 atomic reactor with a capacity of 600 kW, which gave it the ability to spend longer periods under water.


A small, quite sub with an atomic reactor, that’s what they want.

They want to compete with the new generation of German subs.

I wonder if people will still insist that Russians are so broke that they can’t pay for the fuel to run what ever rusted piles of crap they have left over from the Cold War.

I'm not referring to the online Russian leak, I was commenting on the validity of the online forum guesses as to what kind of technology is being developed.

I see. Since you still refuse to read the article in question, what is “anaerobic engine”, why is it a very good idea, and which online forum you keep referring to?
Guesses which as far as I can tell are unsupported, however you seem all too ready to accept them.

What exactly can you tell? What guesses? Project 212A? Further development of VAU-6 maybe? I’m not following you here.
I’m sorry WestPoint23, it’s obvious that we are not on the same page here.
If you care to take the time to read the article in full, then I’m sure will be talking about the same thing here, because as of now, we’re obviously talking about different things.

The concept sounds a bit retarded first off. Diesel submarines are small and cheap but due to their propulsion are short-ranged thus limiting them to more defensive roles closer to home.

Hi danwild6, I also recommend that you read the article. It clearly explains the advantages of anaerobic engine configurations. It’s all in the article.

Nuclear subs are larger and more expensive, both to build and maintain, but can operate for extended periods of time at sea and independent of any external support thus making ideal for the long range strategic role.

All true, but again, as stated in the article, not all subs are built for long range strategic roles, and it’s not the type of the new sub that we are discussing here.
It is possible that the new sub is a test bed for a new, mini-reactor.

Right here;

A second theory is that the submarine would test a new nuclear reactor. That possibility was first mentioned in February of this year in an issue of Nizhegorodoskaya delovaya gazeta (Nizhny Novgorod Business Newspaper) dedicated to the anniversary of the Afrikantov Experimental Heavy Equipment Design Bureau, the leading developer of nuclear reactors for submarines. It says in an article that the bureau last year “developed a project for the new atomic submarine Kalitka, on which a principally new steam generating system, the Phoenix KTP-7I, is being installed.” It is possible that the mysterious Project 20120 is connected with the equally mysterious Kalitka project.


It’s all clearly PRINTED, so please READ FIRST, speculate LATER.

Trying to combine the two by putting a nuclear reactor on what otherwise would be a diesel submarine may seems like a logical move to develop a versatile all-purpose warship relatively cheaply


That’s what I was thinking, I do agree with you there. More and more countries are actively persuing smaller, more versatile subs. German exports have proved that.

(Russia still spends only a fraction of the money on defense that the USSR did during he cold war).


How do you know that? Russian defense budget has always been classified, as clearly shown in CIA fact book.
The only data available is Russian arms export and annual increases in MIC output.

On that note, please let’s leave all kinds of speculation out of this, and talk about the topic at hand.

Does this new sub project display a fundamental change in Russian naval doctrine, or is it an effort to create an affordable export sub for the aspiring regional powers?

Russians obviously did away with massive Typhoon class and producing much smaller, stealthier and faster subs, could this sub be one of them?

AIP boats still use batteries- as they offer more endurance than an AIP system (and more speed) - AIP would be used for `silent running` but at slow speeds (typically 14 days at 5 knots) as an entire AIP system will generate much less power than conventional battiers - typically 400kw vs 3mw for batteries (and 20+ for a nuke boat) - but batteries still need charging - even the latest german and swedish AIP boats snorkel - adding a tiny reactor would eleminate the need for this.

i could see this being fitted to AMUR class of russians SSK`s (which is comparable to the Scorpène class or Type 212) and as allready been shown battery boats are deadly (recent SA boat vs nato anyone)

Cheap, small, fast, quiet, stealthy = very dangerous+great deterrent, aka force multiplier.



Cheap:Anything that involves a nuclear reactor isnt cheap regardless of its size or thermal output, if you want a cheaper means of increasing underwater endurance you do what everyone else is doing and utilize AIP.
Generally speaking half the price of an SSN is its nuclear power plant.

Small: The reason nuclear subs are larger is a weight issue, any reactor regardless of its size requires substantial shielding with lead and that makes them bloody heavy, therefore nuke boats have larger hull forms to increase there displacement. The only boat that does not meet this criteria is the NR-1, if she had been fully shielded she would have sunk at the pier so the entire aft of the boat was sealed off and flooded (12 foot of water has the same density as 1 foot of lead), even then the entire aft of the boat inside and out was a no go area when the reactor was running, on a small boat with a highly specialized and trained crew you can get away with this, not a good idea on a fleet boat.

Fast: With a miniture nuclear reactor providing minimal thermal output and batteries? A full size nuke would run rings around it. An AIP would manage the same speeds if not faster.

Quiet,Stealthy: Full size nukes can run just as quiet, by winding back the reactor output you can shut down all the pumps in the primary coolant loop and utilize natural convection thereby making the reactor plant completely silent. It is doubtful if you could do that with a mini plant because winding that back wouldnt provide enough power to move the boat. Yes running on batteries is quieter but you can do that on a full size nuke too by designing a nuke boat with larger battery capacity. The whole point is if you have a reactor on board giving you an unlimited supply of power you dont need a diesel to augment it.

Very Dangerous: Any boat of any design can be dangerous, that comes down to the crew manning it.

Great Deterrent: Ok, if you say so.

Force Multiplier: Not even going to dignify this with a response.


My question stands, Why the hell would you? What does it achieve? What is the point?

(shakes head in dismay and exits the room again)
