What about the plans to develop a new LRMP aircraft based on Tu-204 platform is it still on the cards ?

Snake65 , How well have the Russian Sea Dragon ASW suite have performed in trials any information on it ?

It’s Novella for Russia. Aleggedly has succesfully passed the tests. No really detailed info or rather – I haven’t been looking into it 🙂
In the end of 2009 it was still under tests and no information on serial production of Novella was available. Apparently there were problems encountered, because the first phase of state tests were carried out in 2005-2006 and were not fully satisfactory, therefore second phase started in 2007.

Does any one have any performance specifications on the new Zarya sonar suite on the Stereguchy class corvette? Information on sonar performance, in general, is hard to come by.

That’s easy

At the end he mentions that the boilers are still leaky even after overhauls, though not as much as before.

Of course they are when operated by undertrained conscripts

What is KTM-6 Next Gen Reactor , Any further details ?

A characteristic feature of Russian nuclear submarine the 4 th generation was to be a new type of power plant. Especially for the new project in the late 80’s developed a new water-water-steam supply system (PPU) KTP-6-85 from reactor KTP-6-185SP (sometimes a false name KPM) with termal power output of about 200 MW by Afrikantov OKB. A distinctive feature of the new type of reactor is so-called integral single-block design in which the reactor itself and its first cooling circuit is mounted in a single package. This solution eliminates from the construction large diameter pipelines (their maximum diameter was reduced from 675 to 40 mm) and, thus, facilitates the natural circulation of coolant at all modes. The latter is one of the key criteria for low noise throughout the boat without the need for continuing the work of circulation pumps and reducing energy consumption on the order of the reactor on its own needs (a higher overall efficiency). This is much more compact than the previous generation, more easy to maintain, more secure and reliable. At the same time, the integration of all systems and components of the reactor in a single body has a negative impact on the maintainability of the installation because of poor accesibility. Due to this the developers of 4-th generation reactors have been tasked to ensure no-service throughout the life cycle of the boat. The reactor is constructed so that it needs recharging twice less frequently than in similar installations on third generation boats.

Sorry for Google translation.

OK-650 reactor on 971,949A,941.. OK-650V is a different reactor

No, it’s just another modification of the OK-650 family. There were OK-650A, B and M before. This is just an upgrade, possibly incorporating some features of the KTM-6 next generation reactor, but nothing completely new.

Good for you.

If I spoke Russian I would. I don’t.

It’s good for you as well as you get documented info from me and don’t have to study Russian.

It has very much to do with the 20 very big missiles and the double hull standard. Pure and simple. Typhoons were nicknamed “water-ferrys” (vodovoz) for good reason.

Well, if the new design was a failure…

I guess this dims the export prospects of the Amur for a few years at least. Hopefully if the Indian Navy opts for Amur for their second submarine line they’ll ask for a European-origin sonar suite.

The trouble with Lyra sonar was appreciated already in 2006, a different organization is working on new sonar since then (I expect two themes elaborated simultaneously – trying to salvage what can be done from Lyra and go for an all-new sonar).

Returning to the matter of how silent Lada is – the comparative trials have shown them to be 6-8 times (that’s around 10 dB) quieter than late 877/636.
