Sub Brief Project 941 Akula is called Typhoon by the west.  

This is long.  Take breaks.  Some of you know how a Nuc Sub reactor works, please do not post how it it works.  I left part of it out because it applies to US boats.

21:25 Written on the port side: "Aggressive plans of USA will not pass!" :D Interesting that you'd run salt water in steam turbine, indeed. I was listening like "is this normal??!". Hot salty water is highly corrosive so there must be some serious material science involved. There is also risk of blowing some dust into the turbine.

1:47 what is that ring thing on the front of the Ohio? I've seen that on so many subs.

Aaron Amick

That is the mount they use to take the dome on and off. it attaches to a crane.

Thanks for putting so much info into one place. Your insights add a great deal to my enjoyment. I think this is a great use for Patreon. I suspect other content creators will need to go to a similar model. This is well worth my donation.

Trevor Hart

Bloody good stuff, thanks! I must up my Patreon amount when I (finally) find a job. I would have loved to hear more about your experiences of listening and tracking these things but I am sure you cannot say much more. Enthralling to hear you talk about the shocked reaction when she first disengaged her primary coolant cycle pumps. Any insight into why they swapped out the original five-bladed screws so quickly?

Joseph Orr

TY Jive, very interesting information. NG did a special on the dismantling of one of the Typhoons. It was amazing how much work it took to disassemble them. The Russians took great care in the task.

IceMike

Very thorough research, always wanted to know more about the typhoons. Engineering masterpieces. Russians are getting good at what they do.

Don Tidrow

I always thought they had just taken a couple of Delta pressure hulls and siamesed them together, but apparently it's a unique design. Will definitely be watching this later in the week, while I'm on travel.

Amazing job Jive!

Captain ACAB

Wait, so the secondary loop is salt water? Or did you skip a secondary/cooling loop exchange for the sake of simplicity? A salt water secondary loop seems absolutely nuts to me, from a corrosion/filtering/reliability point of view. Imagine being a piece of krill going on that ride! Anyway, thanks for such a fantastic lecture. Keep up the excellent work!

El Portal24

Best Video yet, good job. I learned few things - didn't realize Typhoon had so much empty space between hulls. So movie Red October was wrong you cant shoot the missiles from inside. But plenty of space for corrosion to develop. The maintenance on these puppies is like three submarines.

Nick Rowland

The Hunt for Red October was a very, for lack of a better word, formative movie for me. This was awesome for me to watch. Thank you!

Whitzwolf

In the original construction photos the rear "tongue" is rounded but in the midlife upgrade photos it appears its been sharpened off? I assume that's to do with improved water flow over that section

pin_die

Looking at the test depth I am guessing titanium hull? Perhaps less corrosion issues.

Axel

Can we expect sub briefs about older, now decomissioned US sub classes like the Skipjack or Thresher class?

Aaron Amick

The 5 bladed screws were very noisy. cavitated easily. I suspect they planed on changing them out as soon as the 7-bladed screws were ready.

Aaron Amick

There is another loop that I did not talk about.

Aaron Amick

There is another loop in there that I didn't mention. Probably should have. The Seawater is mainly for cooling.

Mark Codding

The Narwhal (SSN671) had the S5G natural circulation reactor system

pin_die

For a moment I thought this si some mad science and everything I learnt was false. Well, there goes my dream. :(

Aaron Amick

I’ll be doing Narwhal in the future. I’d like to have you as a source

Aaron Amick

I'll be in touch when that topic comes up.

Noah Smith

Such a big scary boat, great job jive

Alexander

I can only fall in line with the others, great piece which keeps up with his Object. Lot of new details at least for me and for allother Subnerds out there it's a Sub Brief and quite a long one but still not a lecture. Sincerely Jive well done and thanks Alex

Burn Hard

One of them allegedly had a missile explode in the tube.

Andrew MacDougall

is it true they could operate a typhoon fully from just one hull or the other? were there two redundant crews?

Seahour

Great Brief Jive. Thank you for the work you put into these! I have a thought as well on the towed array. Could it be both you and the sources are correct? Let me explain, if you take a look at the that top picture again. It looks like the port towed array may have been changed to a fat line tactical like the starboard one. Would that allow for the enhance beam formed contact information as well if beam formed with the starboard towed array? Then the top towed array would be a floating wire like you thought?

Mark McGrath

Hey since you can't do this on youtube anymore could you do a what if the Red October was real kind of thing? That would be a good add for this, and since you wont need sources it shouldn't bother youtube.

Largezo

Great presentation, i loved the pictures from the inside. Not often do you get to see what's inside a submarine.

Jakob Marolt

Great video the only thing that was missing for me was why was Typhon retired, you did tell us how but not why. Was it maintenance issue, too expensive to operate, or Russian realized that is better to have more smaller SSBN instead of six very big submarines?

Ace Tanker

Oh nice a long video! That’s a nice surprise 😊

Aaron Amick

cost. It was too expensive, but U.S. paid for 3 scrapings. So 3 got scrapped and 2 are mothballed.

arash

Amazing work thank you!! can you upload them as private posts on youtube so that we can watch it on youtube app?

Steven Cross

can ya give a link to that guys imgur because all I found was a picture of Goku :p

arash

I watched the video again and again, now I understand why do I love atomic subs so much, I was always fascinated by Doble and White steam cars, and an atomic sub is the ultimate steam machine

Allen

Thanks Jive, it would be good to hear more about beamforming application to Sonar,

T. Owen D’arreigh

Great presentation Captain Jive Turkey. One quick question: Much has been made of the fact that our Navy does not allow photos of reactors. In my own research I have found very few pictures of reactors, even in decommissioned/obsolete submarines. But you show one of a Typhoon’s reactor, rod assembly etc in this brief. I was surprised to see it. Does it concern you, especially since they still operate one of these? Thank you for the awesome content.

I found there is interesting information on the nuclear-powered civilian ship NS Savannah.

pat.h.n123456789@gmail.com

It is a great surprise that the Typhoon's reactor uses seawater as the secondary steam loop fluid. All reactors I have read details of use a closed loop of fresh water to drive the turbine, and heat is rejected from this water through a condenser into seawater.
