Project 971: Akula class

https://www.youtube.com/watch?v=K6IIH6lbMSc

This video claims the two akula's that are with the carrier have Kaliber missiles.

Any ideas what's going on here?

A Trafalgar class with what looks very much like the SOKS sensor off the sail of an Akula

I seem to recall reading that UK had their own system similar to SOKS but it would seem pretty odd to use the same rake angle, on the other hand where could they have gotten one from?
From what I've seen Nerpa was delivered sans-SOKS, seems fairly unlikely that Russia would sell one?
Severodvinsk & Boreis don't have obvious SOKS so maybe it's considered obsolete tech, or never actually worked?

Edit: also since it was in the comments & I'd failed miserably to re-find it recently when I wanted to, this is a really good imgur album about the class https://imgur.com/a/pZCb0

Inside Akula-II [New]

On the last scene, the door has the pressure rating of the bulkhead and volume of the section .

It is a door on the Kursk, it was on the bulkhead between the main section and the torpedo room (they forgot to close on of these as I remember)


Anyone can read the pressure rating of the door under the damage/rubbish?

It seems like 100 for me.

Upgraded Russian Nuke Sub SSN Leopard to Join Navy in 2019

Zvezdochka Ship Repair Center will complete in-depth modernization of the Project 971 Leopard multirole nuclear-powered submarine in 2019, an insider in Russian defense industry told Mil.Today.

"She'll leave the dockyard next year and be commissioned in 2019. Retrofitting of the second sub in the series, Volk, will finish after Leopard’s handover", said the interviewee

As for earlier reports, Leopard was supposed to return to the ranks in 2018. Thus, the submarine’s delivery faced the one-year extension.

Modernization of the 3-generation attack subs includes renovation of weapon systems, radio electronics and sonars. In particular, Leopard and Volk will be capable to launch Caliber cruise missiles. According to Izvestia, combat features of these subs after upgrading will reach parameters of Project 885 Yasen fourth-generation submarines

As for the expert, such delay in delivery of the submarines is accounted for the shipyard’s heavy workload. Hopefully, while the technologies are mastered on Leopard, further subs would be upgraded faster, Nikolayev added.

K-328 Leopard nuclear-powered attack submarine was built by Sevmash Shipyard and commissioned in 1992. In 2011, the sub was docked at Zvezdochka for interim overhaul and in-depth modernization.

Her sister ship, K-461 Volk, joined the Russian Navy a year earlier, in 1991. The sub arrived at Zvezdochka in the summer 2014. Initially, the retrofitting was planned to finish in 2017

Not at all convinced about Izvestia claims the Leopard & Volk will be brought to near Yasen capabilities, but if the rebuild is extensive enough they could be extremely effective boats, even against USN Virginias & Seawolf.

No way in hell they will be even close to Yasen, reporters are talking out of their asses as usual but with Kalibr/Onix functionality they will go from being able to attack ships from several dozen kilometers away to attacking from several hundreds kilometers away.

And from zero to couple of thousand kilometers for land targets (but I don't think they should hassle with this, there are plenty of other vessels that can deal with ground targets)

Estimate would be that they have space for roughly 40 torpedoes/cruise missiles.


So if wiki and that table George1 posted ( https://www.russiadefence.net/t5541p150-russian-naval-construction-plans-and-update#206866 ) are correct they have up to 6 Akulas that are undergoing upgrades and 3 in service. Combined with Oscars and Yasens these would be enough to get Russian Navy up to speed while production of new SSNs stabilizes.

Having up to 9 Onix capable nuke subs would help a lot. And this upgrade would automatically make them Zircon capable as well.

They are sitting on something pretty good here, hope they put it to use.

These Akulas (and also the other Soviet nuclear subs) do carry the GRANAT cruise missile. But that was nuclear tipped.

The Russian Navy is quietly upgrading all its subs to be able to launch Kalibr cruise missiles from their torpedo tubes.
Even their oldest nuclear sub (Victor III class) are now getting Kalibr capable. One of them was reported to fire one on an exercise a year ago.

I suspect that some of their surface units can launch Kalibr from their torpedo tubes as well. After all, we have seen in videos, Udaloys and Peter the Great launch anti-sub versions of the Klub missile from torpedo tubes.

Good to hear. Having so many ships up to fresh standard is great.

But important part here is number of subs. Getting extra 6 SSNs into service will go a long way in this dicey period.

Akula "export" version. Big deal. Goes to show that they should never waste time on India and their bullshittery.

Honestly I am surprised that Yeltsin did not deliver to USA blueprints for these things long ago.

And these are same dipshits that claimed that they will rent Severodvinsk SSGN?

Doubt there is any real harm done other than to Indian already non-existent reputation.

Still time to add certain Indian neighbor to Iskander export list and give them nice startup discount. Fair is fair.

it's a Russian akula as it is leased to India. India doesn't actually own the vessel.

Although, even though the US had a chance to see the inside, it doesn't make a difference as the only way to learn of ships weakness is through schematics. Which India doesn't have. But the part of the agreement signed was no foreign specialists onboard. Which India broke directly which means Russia can go after India legally.

In this case, its best Russia sells India basic and export only equipment. Ones that they don't care if US gets hands on. Cause otherwise, India is very untrustworthy

You are right they aren't.    The two-seater PAK-FA fiasco was giving us a hint of their mentality.   From all the yapping you
would think that India funded the PAK-FA project itself.   They want the latest and the greatest for cheap.    Russia should
do as the US with the F-22 and simply refuse to export it or work on any derivative projects.    For some reason everyone
and his dog thinks Russians are stupid.

There is no such thing has akula "export" model that akula was a standard one leased to India.

this would depend where the indians let them go in the sub only certian areas of the sub would be "secert" stuff like crew quarters is harmless.

That said, assuming this true (because just because someone says something on tumblr doesn't make it true") this would depend where the indians let them go in the sub only certian areas of the sub would be "secert" stuff like crew quarters is harmless.

Besides the point where they went or had access to. Political fallout is still the same if true.

Nerpa/Chakra appears to have been nerfed, eg SOKS sensors have been removed from the exterior.

Depends if nothing was added in place, I do not have access to information regarding that submarines specifics.

The Chakra is an Improved akula which is one of three total the Russians built. I'd need to see alot more design specifics to say it was downgraded. Since that would be hard to do in the short time the Russians worked on it considering it seems to take them over 6 years to modernize a single submarine. I have great doubts it was downgraded since that would involve swamping most of the subs inner parts and equipment with lesser ones.

It is downgraded.
If it wasn't, is it even possible to lease or lend it legally?
IIRC Russia has laws against this because they have foreseen stuff like this happening.

Guys, India probably already delivered blueprints for this thing to USA years ago. If not officially then some Indian locals on Uncle Sam's payroll did it.

And everyone, Russia first and foremost, knew they would before they even leased it.

No way that sub contained anything sensitive or too new.

India doesn't have the blueprints to this. Its leased, not sold.

And it's staffed by Indians who are not immune to cash.

you assume the russians follow the law all the time, they do not just like any country and government they follow laws when it suits them.
