I can confirm that propulsion problems have been smoothed out, but who told him that sonar suite is ok I have no idea. Sonar integration with BIUS is the main reason why SPB is accepted by Navy for “Trial Exploitation” only.

30 dB drop for Lada is an exaggeration, perhaps if you compare to first hulls of 877 it could be true under specific circumstances, but definitely not if compared to latest 636s. Double hull means not only more volume for silencing but also larger geometry and acoustic interaction between two hulls (specific discreets appear in spectre) which is ugly thing against LF sonars.

Yeah.:D

-Is there any information on the Poliment radar? Brochures, news articles, specs…

-Is Poliment serving the roles of both Long-range Volume Search and Air Search/Target Acquisition or is there a second radar like Fregat for Air Search?

-Is the Redut-K SAM a derivative of Shtil or an all-new system? What are its parameters?

-Is the 91R anti-sub missile part of the RPK-9 Medvedka system?

Thank you.

– Yes. Speculations and insider tidbits. It’s not for export yet 😀

– At least the first hull may have Fregat+ for volume search, atlhough Poliment is expected to provide volume search there are no specs on capacity and range

– Redut-K is the “shorter” part of S-400 – SAM Vityaz’, so it has nothing to do with Shtil

– 91R is the anti-sub missile of Club family and has nothing to do with cancelled Medvedka

Severodvinsk has left Suhona dry-dock.

snake65 can you please check that image of Torpedo that put up in post# 632 its in Russian language.

Do you know any progress as been made on UGST-M torpedo ?

Thanks

That image deals mainly with types of engines used on different torpedoes. It says that UGST-M is in development phase and uses a 600 kW turbine D-19T with Hydrazyte + T1 (kerosene) fuel. Russian name for same torpedo is Fizik-2 with 800 KW turbine.

8 SM-346

Isn’t it just producer’s index for the same thing?

Well, it’s 1155.1 Admiral Chabanenko meaning that the other 1155 is Admiral Kharlamov or Admiral Levchenko (Severomorsk has the new Kolchan FCS aft) and 956 Gremyaschy making the other one to be Admiral Ushakov. Can’t see anything else.

What is your image showing? And what is your point?!

It shows 5 torp ports of the same size.

^^ Similar to Akula , what is that bumb on the hull just below the sail ? Sonar ?

Looking at the unevenness of the hull and sail , makes me believe its partially completed they need to perhaps rubber coat it ( anechoic tiles )

Seems quite smooth to me, much better than YD at “launch”.
The “bulb” could be this
