    Yes. Its the reactor/area that is being worked upon. Not sure whats going on - an upgradation or removal for scrapping. But the two 945 boats (Karp & Kostroma) were up for an upgradation programme (2015-2017/3 years) and enter active serivce. I've posted that status of Russian navy ships in the other thread.

    Works on the repair and modernization of nuclear submarines of Project 945 are suspended

    As reported on April 27, 2017 web resource FlotProm, the modernization of the main titanium nuclear multipurpose submarine B-239 "Carp" project 945 (cipher "Barracuda") of the Northern Fleet and was limited to the unloading of fuel from the ship in 2014. According to the source FlotProm in the defense industry complex, the resumption of work is unlikely.

    "The modernization of the Carp is too expensive and laborious, the candle is not worth the candle," the source said. "Today, the Defense Ministry has much more relevant projects whose expediency is not questioned."

    The source added that he was not sure about the very possibility to bring the structurally complex "Karp" to the requirements put forward by the Defense Ministry to the submarines of the 4th generation, and also stressed that the final decision has not yet been taken.

    According to the founder of the site "Storm of the depth" by Andrey Nikolayev, if the expediency of upgrading the 945 submarine raises questions, the money saved for the modernization of Carp and Kostroma (the second submarine of the project, which was planned to be updated after Carp - etc.) It is more logical to direct the construction of new "Ash".

    "Each submarine is relevant at the time, if it is possible to get modern ships, such as the modernized Yaseni, it's more logical to concentrate on them, or to try to get 971 projects back in. Perhaps, it is more economically feasible," the expert shared his point of view.

    The Ministry of Defense signed a contract with the Severodvinsk Ship Repair Center Zvezdochka to repair and upgrade submarines of Project 945 B-239 Karp and B-276 Kostroma in 2014.

    It was assumed that the Barracuda will receive new sonar stations, combat information management systems, radars, GLONASS / GPS navigation systems and weapons systems.

    In February 2015, it became known about the suspension of modernization, but the press service of the company announced the continuation of the repair work.

    The submarine "Karp" became part of the Northern Fleet in 1984, "Kostroma" - in 1987, withdrew in reserve in 1998 and in 2000, respectively. Both submarines are built at the Nizhny Novgorod shipyard Krasnoye Sormovo.

    mod wants there refurbished submarines to have noise levels like yasen and newest missile weaponry- that means cutting hull, new systems, and new propellers, shipyard wants huge price for that, refueling is having problems some things have to be cut,  and now it turns out there is low number of titanium welding skilled staff, even tu-160 constructors had problems to gather welding staff since no new personell training was done for 20 years.
    its hard to tell but it seems you can buy new yasen-m for those 2 submarine upgraded.

    Let's be real these things were utterly pointless to modernize the cost wasn't worth it from day one, The Akula make sense, the Oscars make sense.

    These things are dated and Russia only uses them since it's all they got right now.

    Cutting this project was a wise idea and the better.

    The Sierra was the capable expensive model... it is better to have them in service than to scrap them.

    The cost of upgrading them is spending money in areas that have not had money spent for too long... it is putting Russians into work, so it is well invested money.

    The point is that there is no capacity for building more Yasen-Ms than they are already making so upgrading these subs still makes sense as the money earned will be reinvested in improving technology in important areas.

    no it was not, marginaly in some areas but akula is ahead of it , let alone yasen.... its better to have whole old ussr fleet in service than this today, but modernisation and new weapons must come.

    no. that spending is inflation and making people poorer , titanium welders are already very busy tnx.

    1 yasen every 3 years for next 2 decades is well enough and good enough capacity for money available thats coming along.

    the Sierras at this point are too old imo...
    Keeping them in service is fine but modernizing them is pointless....

    Better invest the funds into newer Subs like the Yasen which can still be Upgraded even more in the future with newer systems...

    SeigSoloyvov wrote:The Akula make sense, the Oscars make sense.

    Oscar's make sense because for its role, the IMPORTANT parameters can be easily upgraded (the VL Systems from the Granit launchers to UKSK) and other side systems like the sonar can also be replaced to increase its combat effectiveness... Since Other areas like Noise Acoustics and such (Where upgrading them is nigh impossible without changing the hull which would be expensive as hell) was of no concern for the Oscars.... I mean sure the 949AM has significantly better acoustics than the Oscar Is (even supposedly surpassing the Akula I) but its still short of an Akula II and any furthur 4th Gen Sub (Which at this point is the norm) hence dangerous for frontline Offensive operations (Oscar IIs would make good prey for NATO SSKs/SSNs in one way to put it i guess but for sure the Russians would attach at least one Yasen/Kilo class as an escort for the Oscars)....

    Akula Is.... the Improved Akula Is i'd say was taking the upgrade to the limits... a design that is 2 years older than the Sierras.... Even i was surprised that the Russians managed to modernize the Akula Is... but its still short of the Akula IIs... Make sense... Before the Improved Akulas came out, I'd say that upgrading the Akula Is also doesn't make sense BUT the russians somehow managed to upgrade it to a barely acceptable level for a modern Frontline Submarine so... yeah...

    But i'd rather divert funds to more Yasens or even Husky's in the future.... Don't get me wrong, Akulas are GREAT subs for its time but she's aging alright.... and she's aging pretty well...

    *Note all of this is IN MY OPINION....*

    Sorry, but that is the height of stupidity.

    If something is going to be in service then it needs to be kept up to date as much as possible.

    You wont get to choose which boats get involved in international incidents and the boat involved should not be a 1980s technology unupgraded piece of crap.

    Think about computer power in the 1980s. Think of safety performance in the 1980s. No upgrades? Fuck off you tight bastard... would you work for a company with 1980s period cars that wont upgrade them because that would just waste money they could spend on other things...

    They are introducing new weapons and new C4IR systems... are you telling me you only want your new vessels tied in to your command and control and communications, intel and recon system with old computers too?

    Get real.

    Mate i never insulted you in that statement so whats with the insults?

    Like i said, its all in my opinion and IS the reason WHY i want to discuss it here......

    Now for the argument....

    GarryB wrote:would you work for a company with 1980s period cars that wont upgrade them because that would just waste money they could spend on other things...

    How about because they could spend money on newer cars to replace the 1980s period cars....

    How much will the upgrade cost anyways? From what i heard, even the overhauls of the sierras were delayed due to pricing issues in 2015... (https://lenta.ru/news/2015/03/19/sierra/ , http://svpressa.ru/war21/article/114524/)

    At the same time, i can see where you are coming from.... Having upgraded Subs even if they are old does help.... However i still believe that its better to move to the Yasens....

    Where did I insult you?

    If you say things I think are stupid I will say so... don't take things so personally.

    How about because they could spend money on newer cars to replace the 1980s period cars....

    But they can't.

    If they don't spend money on upgrading existing vessels then keeping that money aside to spend on newer models does not work... they have a lot of different things they need to spend money on... if they don't spend money allocated to upgrade in service vessels they wont just hold that money to buy extra Yasens in 5 years time when they are ready to lay down a new one... what are the Russian Navy supposed to do in the mean time? Use a crapped out old sub that is not compatible with the current communications systems or new weapons?

    That is just silly.

    At the same time, i can see where you are coming from.... Having upgraded Subs even if they are old does help.... However i still believe that its better to move to the Yasens....

    I would suggest they are already making the number of Yasens that they can afford and need... it is not just about building space, but you need to operate it from somewhere too.

    The Sierra was the follow on to the Alpha class sub and are made of titanium... of course they are cheap to upgrade... geez... :rolleyes:

    Like I said, these are expensive boats, and also very capable for their time and with proper upgrades could be very very capable boats.

    It has a smaller turning circle than any US submarine and is light and fast and deep diving... the Sierra II boats were even quieter and had improved sonar arrays.

    The point is that upgrades in the Russian navy are all about standardisation... modular new components fitted to make older boats compatible with new standard systems... fitting them in will be a pain but once they are in then it is standard so any Russian port will be able to deal with them in terms of support, training, maintainence, etc.

    If you want to have it the different boat then fine... a mobile support team you fly around to whatever Russian port it docks at so it can be supported properly would be expensive and annoying.

    Yeah... I did more research into the Sierras...

    I guess what you're saying makes sense.... curious though on how would they cram the new systems in since that was one of the issue points for me.... Cramming it in and somehow making it work with what they have that cannot be modernized or replaced with better versions (Only Overhauled)

    Many bits on a sub are already modular, and newer bits tend to take up rather less space than older bits.

    A lot of the brand new modular bits are based on the bits they put in the Sierras and Alphas.

    The wiring and piping will all need to be replaced anyway... but that is generally kept together anyway.
