    Currently Russia operates 1 Yasen. The second one Kazan should be commissioned in the next few years.

    I didn't realize you had access to classified information about US Nuclear Submarine maintenance...

    Oh wait...you don't?

    Oh right you're talking straight out your ass~.

    I guess a genius like you can search the net for some of the reports that came out the last few years from different agencies/offices/think tanks that revealed the dire straits in which the maintenance of ships/subs and planes in all of the american forces is.

    Arrow wrote:The Russian navy also has a problem with the small number of nuclear submarines. Russia currently has two modern 885 / M and a few 971,945 units. Additionally, several 949As. Compared to the US underwater fleet, this is not much.

    Only 688I USA ships have 23 submarines, 688 submarines with VLS another 8. You can add the older 688Is. Russia only has a few submarines of tier 688I or better. This group also includes 18 Virginia class and 3 Seawolf. This makes over 50 SSNs. When you count your allies, there's even more. With such a disproportion, Western forces can mess up a lot even in the vicinity of Russia, especially the Arctic, Barents. Russia does not have the strength and means to fight such powerful SSN forces even in the vicinity of its territorial waters. Western SSNs may track and attempt to destroy Russian frigates and Corvettes operating in the northern waters. Such an advantage in the SSN may significantly hinder the Russian defensive actions in the areas of their borders and the protection of their SSBN.

    I wonder if Russia will order more 885M submarines. It shouldn't end up in a series of 9 units.

    I will have to refrain what others said here. This ignores the quite capable Russian conventional submarine fleet, like the Kilos, which the US does not have. Russia has several older nuclear attack submarines either active, in reserve or in refit, like Akula, Sierra, and Victor types. Some of which would be highly effective when modernized and into service. A lot of the Akulas were only launched in the 1990s and had minimal use so are in good shape. A lot of these are being refit with Kalibr naval attack missiles, even the Kilo conventional submarines can often fire Kalibr, and Russia is building 6x Yasen types at a time.

    There are a lot of reports that the 688i submarines are in a less than optimal condition being several decades old. At least a decade older than the Akulas and unlike the Akulas kept into active service for most of this time. The Virginias, while a successful design, recently were in the news because of a scandal where substandard steel was supplied to build them so they cannot dive at the project depth because the hull cannot withstand the stress. Their long term hull integrity is also questionable. This had been going on for such a long time the specialist responsible had already retired by the time it was discovered. So you can see how far the institutional rot has gone there.

    Oh really? what offices and agencies, also "think tanks" LOL those don't matter at all as they aren't given such information and even if they do they aren't allowed to comment on it to the public, so any claims of such are false and bogus.

    So show me buddy what US agencies and offices state half the US sub fleet is in need of dire maintenance

    I'll be waiting.

    the reality is you just an online anti-US troll spouting lies and other crap because it makes you happy to think so. That's all this is, fact is there is no evidence of this claim maybe some anti us sources have stated this but that's like me taking everything that comes out of the pentagon has fact.

    Yasen lacks pump jet. The upcoming Khabarovsk should be able to go toe to toe with Seawolf / Virginia. In any event, Russia needs 10 Yasen and 10 Khabarovsk in order to be able to challenge America in undersea.

    There has been stories in the media the last couple years that aren't typical of the USN.

    Bedbugs found on US Navy submarine USS Connecticut

    (CNN)The USS Connecticut, one of the most elite submarines in the US Navy, was infested with bedbugs, and some crew members chose to sleep in their cars.
    https://www.cnn.com/2021/03/11/us/bedbugs-navy-submarine-trnd/index.html

    With the Navy’s submarine maintenance woes, there may yet be hope
    https://www.defensenews.com/digital-show-dailies/navy-league/2019/05/08/among-the-navys-submarine-maintenance-woes-there-may-yet-be-hope/

    The hapless Boise returned from a patrol in 2015, and it hasn’t gone back on patrol since. The inactivity has caused Boise to lose its dive certification, one of three attack subs in the fleet currently unable to submerge. It’s been four years and counting, and now it wasn’t even funded in the Navy’s fiscal 2020 budget request.

    Yasen lacks pump jet. The upcoming Khabarovsk should be able to go toe to toe with Seawolf / Virginia. In any event, Russia needs 10 Yasen and 10 Khabarovsk in order to be able to challenge America in undersea.

    Russia had a Kilo class submarine with a pump jet in 1990.

    It was a design choice. But you are sitting here saying that pump jet is superior full stop. Mad It isn't. If it was, the Yasen would have a pump jet.

    First, pump jets don’t necessary mean quieter running. Propeller blade shape is actually more important, reportedly. Second, most common form of a pump jet employed in submarines, the ducted propeller, is most advantageous at lower speeds, about up to 10 knots, and rapidly lose efficiency above that level, requiring putting more power to the propeller, which actually defeats the noise advantage, as more power = more noise generated by the machinery. So the pump jet is best suitable for the somewhat slow-running subs like boomers, and not much so for attack subs. And, indeed, Russian boomers use pump jets since the project 941 (Typhoon/Akula class), but Yasen trades a somewhat higher noise of the screw for higher efficiency at speed, which allows it to use less power at the same speed. Less power=quieter at that speed.

    In submarines design, you pick a speed range, and you pick your quiet level.

    BTW, many subs in the same class can have different propellers and therefore are optimized for different missions. The operational depth of the sub has a lot to do with choice also. Water is more compressed at depth so less cavitation anyway.

    As I've said a few times, pump-jets are good at reducing cavitation noise, but given that russian subs cruise deeper in colder waters, that is not the problem for them as it is with US subs with shallower operating depths running in warm waters including the tropics.

    Agree especially in one key aspect - if pump jets were all they are cracked up to be, then the Yasens would have too. The fact that they don't (while the Boreis do) is a clear indicator that other factors come into play, not just the feeings of murican armchair admirals and fan-bois. Laughing

    Kazan will likely be in service before the years end, and Novosibirsk stands a reasonable chance of being done with trials in the same timescale.  In 2022 we'll see both Krasnoyarsk and Arkhangelsk finishing trials.

    With some luck that will be 1x 855 and 4x 855M by end-2022 or early 2023.  Thats a much better prospect than you are alluding too. Deliberate misinfo attempt or genuine error?... Hmmm...

    I would think that updates to the electronics would be mandatory, air defence -update to S-350s and take out 4 Granits and replace with 16-28 Tsirkon or Kaliber. Maybe improved drone close in air defence and done.

    It also has the enormous advantage of having SSKs that can operate in shallow waters much more cheaply and efficiently than SSNs can which is a serious gap in Americas inventory.



    GarryB There is no point in including new Russian aircraft carriers in these talks. Two decades have passed before they are created. They can only be considered after they have laid the keel for a new aircraft carrier. It is not known when this will happen. Not fast.

    They have been testing pumpjets on a Kilo class sub for quite some time... the fact that they chose not to use it suggests they have good reasons to do so.

    Russia does not need to challenge the US... and even if they did... how exactly would have twenty very expensive submarines achieve that?

    Submarines are only useful if they are invisible and near Russia their SSKs are better at that than any SSN anywhere.

    If they hit their latest target 1/2 the time would still be 8 years!!!

    Tying up one Kirov for 8 years is not the end of the world... they still have Slava class cruisers and one other operational Kirov that could escort the Kuznetsov around the world.

    A few upgraded old destroyers would be ideal to support world wide operations because their size should allow good endurance while the newer ships patrol the waters around Russia and keep the home country safe.

    GarryB There is no point in including new Russian aircraft carriers in these talks. Two decades have passed before they are created. They can only be considered after they have laid the keel for a new aircraft carrier. It is not known when this will happen. Not fast.

    When you are planning you have to allow for what happens when you achieve your goals and their goals will be that probably by the mid 2030s they will have a CVN in the water fitting out supporting Kuznetsov operations... likely later on with two CVNs and perhaps four or six Helicopter carriers of the 40K ton class based on the two currently laid down would mean at best they could probably handle two major situations, where cruisers and destroyers and a CV/N could be sent to two locations allowing for one CV/N to be in dock or refit.

    If you are not planning to have 10 CVNs then that will effect how many destroyers and cruisers your need and the timescale you will need to have them ready by... otherwise like the UK you might find you have two new aircraft carriers but no decent ships to escort them both on actual missions because the funding all went to these two aircraft carriers and their enormously expensive fighters while neglecting the support ships and escort ships they actually need to operate safely and effectively.

    On the cost of the fleet that Russia needs

    In the previous article " On the fleet that we need ", I outlined in the most general terms the composition of the fleet that would meet the requirements laid down in the Decree of the President of the Russian Federation of July 20, 2017 No. 327 "On the approval of the Fundamentals of the state policy of the Russian Federation in the field of military -marine activities for the period up to 2030 ".

    It turned out, of course, on a very large scale. We will need aircraft carriers, missile carriers, new types of submarines, destroyers and all sorts of other things. And, of course, questions arise - are we capable of building such a fleet technically, and will we pull it economically?

    Just because the americans can´t design and build a proper screw for there subs doesn´t mean that pump-jets are better.

    The same folks that keep on telling us that western subs are quieter, western sonars are better, pump-jets are better then screws told us the last 20 years that the F-35 is the best fighter jet ever developed, with unmatched capabilities... and now the americans need a new fighter jet (propably a slightly modernised F-16) because the F-35 turned out to be a lemon.

    Looking at real facts: russian subs are faster and can dive deeper then western ones. They´re equipped with rocket-propelled torpedos, super-cavitating torpedos, ASW missiles with far greater range then western ones, and now with tube-launched anti-ship and cruise missiles and soon hypersonic missiles. The only way westerners can still claim "superiority" is by unproven measures like "quieter" and "sonar better".

    Russia leads the world in things like nuclear reactors/propulsion, there rocket engines are unmatched, metalurgy and welding capacities are world leaders, but still some people try to tell us that somehow russian engineers are unable to build quiet subs. Rolling Eyes

    Well tbh the soviets were like 30 years behind in CNC machinery compared to Japan and the US until they allegedly bought it from Toshiba in 1988 I think. Before that their screws were very primitive and caused a lot more noise from cavitation and vortices, due to extreme backwardness in precision manufacturing compared to western SSN screws. Idk how much they've bridged the gap by now,but I believe it's safe to assume their Victor 3s and sierras, have garbage screws unless they were replaced.

    Didn't kvs already address this to be a fraud? BTW I like the logic behind the idea that the Soviets could create a space station but couldn't create a CNC machine....it's like saying Aquaman has drowned in a bathtub.

    Didn't kvs already address this to be a fraud? BTW I like the logic behind the idea that the Soviets could create a space station but couldn't create a CNC machine....it's like saying Aquaman has drowned in a bathtub.
    I cant find any english info about the claim that soviets had to pruchase japanese CNC machinery for their screws being a fraud

    Found kvs post on the CNC subject:

    Ah the Toshiba myth. That's right Soviet engineers could never create NC machinery that could produce the metal part
    geometry needed. Even though the USSR had world leading understanding of the science and applied mathematics of
    fluid boundary layers and turbulence. The USSR could make a world leading propeller design, but couldn't produce it.
    What a retarded joke.

    Anyone who spends any time thinking about this "insurmountable" problem would realize it is the usual NATO quasi-racist
    propaganda. They could produce the right geometry by hand if they had to, down to 0.1 mm. It's not like they needed 10 million propellers
    per month. This trope is the same one as the "Soviet ICBMs were not accurate". More pap for uneducated saps who don't
    know what laser gyroscopes are and what determines the accuracy of a missile (hint: it ain't much besides the gyroscopes, missiles
    aren't sailing ships where the crew performance with the sails and astrolabe matters). The USSR had good solid state ring laser
    gyroscopes as of 1970 (glass-ceramic).

    This is also another case of Fantasy vs Reality, and unsubstantiated claim vs a real-world incident/event.

    Fantasy: Russian/Soviet CNC machines were crap, which lead to having loud subs. Rolling Eyes

    vs

    Reality: A Soviet era nuclear attack sub, Project 971 (Akula Class) went an entire month in the Gulf of Mexico undetected by the USN, and congressmen were concerned.

    Russian attack submarine sailed in Gulf of Mexico undetected for weeks, U.S. officials say

    A Russian nuclear-powered attack submarine armed with long-range cruise missiles operated undetected in the Gulf of Mexico for several weeks and its travel in strategic U.S. waters was only confirmed after it left the region, the Washington Free Beacon has learned.

    It is only the second time since 2009 that a Russian attack submarine has patrolled so close to U.S. shores.

    The stealth underwater incursion in the Gulf took place at the same time Russian strategic bombers made incursions into restricted U.S. airspace near Alaska and California in June and July, and highlights a growing military assertiveness by Moscow.

    The submarine patrol also exposed what U.S. officials said were deficiencies in U.S. anti-submarine warfare capabilities—forces that are facing cuts under the Obama administration’s plan to reduce defense spending by $487 billion over the next 10 years.

    The Navy is in charge of detecting submarines, especially those that sail near U.S. nuclear missile submarines, and uses undersea sensors and satellites to locate and track them.

    The fact that the Akula was not detected in the Gulf is cause for concern, U.S. officials said.

    The officials who are familiar with reports of the submarine patrol in the Gulf of Mexico said the vessel was a nuclear-powered Akula-class attack submarine, one of Russia’s quietest submarines.

    A Navy spokeswoman declined to comment.

    One official said the Akula operated without being detected for a month.

    "The Akula was built for one reason and one reason only: To kill U.S. Navy ballistic missile submarines and their crews," said a second U.S. official.

    "It’s a very stealthy boat so it can sneak around and avoid detection and hope to get past any protective screen a boomer might have in place," the official said, referring to the Navy nickname for strategic missile submarines.

    The U.S. Navy operates a strategic nuclear submarine base at Kings Bay, Georgia. The base is homeport to eight missile-firing submarines, six of them equipped with nuclear-tipped missiles, and two armed with conventional warhead missiles.

    "Sending a nuclear-propelled submarine into the Gulf of Mexico-Caribbean region is another manifestation of President Putin demonstrating that Russia is still a player on the world's political-military stage," said naval analyst and submarine warfare specialist Norman Polmar.

    "Like the recent deployment of a task force led by a nuclear cruiser into the Caribbean, the Russian Navy provides him with a means of ‘showing the flag’ that is not possible with Russian air and ground forces," Polmar said in an email.

    The last time an Akula submarine was known to be close to U.S. shores was 2009, when two Akulas were spotted patrolling off the east coast of the United States.

    Those submarine patrols raised concerns at the time about a new Russian military assertiveness toward the United States, according to the New York Times, which first reported the 2009 Akula submarine activity.

    The latest submarine incursion in the Gulf further highlights the failure of the Obama administration’s "reset" policy of conciliatory actions designed to develop closer ties with Moscow.

    Instead of closer ties, Russia under President Vladimir Putin, an ex-KGB intelligence officer who has said he wants to restore elements of Russia’s Soviet communist past, has adopted growing hardline policies against the United States.

    Of the submarine activity, Sen. John Cornyn (R., Texas), member of the Senate Armed Services Committee, said, "It's a confounding situation arising from a lack of leadership in our dealings with Moscow. While the president is touting our supposed ‘reset' in relations with Russia, Vladimir Putin is actively working against American interests, whether it's in Syria or here in our own backyard."

    The Navy is facing sharp cuts in forces needed to detect and counter such submarine activity.

    The Obama administration’s defense budget proposal in February cut $1.3 billion from Navy shipbuilding projects, which will result in scrapping plans to build 16 new warships through 2017.

    The budget also called for cutting plans to buy 10 advanced P-8 anti-submarine warfare jets needed for submarine detection.

    In June, Russian strategic nuclear bombers and support aircraft conducted a large-scale nuclear bomber exercise in the arctic. The exercise included simulated strikes on "enemy" strategic sites that defense officials say likely included notional attacks on U.S. missile defenses in Alaska.

    Under the terms of the 2010 New START arms accord, such exercises require 14-day advanced notice of strategic bomber drills, and notification after the drills end. No such notification was given.

    A second, alarming air incursion took place July 4 on the West Coast when a Bear H strategic bomber flew into U.S. airspace near California and was met by U.S. interceptor jets.

    That incursion was said to have been a bomber incursion that has not been seen since before the Soviet Union collapsed in 1991.

    It could not be learned whether the submarine in the Gulf of Mexico was an Akula 1 type submarine or a more advanced Akula 2.

    It is also not known why the submarine conducted the operation. Theories among U.S. analysts include the notion that submarine incursion was designed to further signal Russian displeasure at U.S. and NATO plans to deploy missile defenses in Europe.

    Russia’s chief of the general staff, Gen. Nikolai Makarov, said in May that Russian forces would consider preemptive attacks on U.S. and allied missile defenses in Europe, and claimed the defenses are destabilizing in a crisis.

    Makarov met with Army Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, in July. Dempsey questioned him about the Russian strategic bomber flights near U.S. territory.

    The voyage of the submarine also could be part of Russian efforts to export the Akula.

    Russia delivered one of its Akula-2 submarines to India in 2009. The submarine is distinctive for its large tail fin.

    Brazil’s O Estado de Sao Paoli reported Aug. 2 that Russia plans to sell Venezuela up to 11 new submarines, including one Akula.

    Russian Foreign Minister Sergei Lavrov said Moscow’s military is working to set up naval replenishment facilities in Vietnam and Cuba, but denied there were plans to base naval forces in those states.

    Asked if Russia planned a naval base in Cuba, Lavrov said July 28: "We are not speaking of any bases. The Russian navy ships serve exercise cruises and training in the same regions. To harbor, resupply, and enable the crew to rest are absolutely natural needs. We have spoken of such opportunities with our Cuban friends." The comment was posted in the Russian Foreign Ministry website.

    Russian warships and support vessels were sent to Venezuela in 2008 to take part in naval exercises in a show of Russian support for the leftist regime of Hugo Chavez. The ships also stopped in Cuba.

    Russian Deputy Premier Dmitri Rogozin announced in February that Russia was working on a plan to build 10 new attack submarines and 10 new missile submarines through 2030, along with new aircraft carriers.

    Submarine warfare specialists say the Akula remains the core of the Russian attack submarine force.

    The submarines can fire both cruise missiles and torpedoes, and are equipped with the SSN-21 and SSN-27 submarine-launched cruise missiles, as well as SSN-15 anti-submarine-warfare missiles. The submarines also can lay mines.

    The SSN-21 has a range of up to 1,860 miles.

    In the technology thread on this forum companies in Denmark and Germany are buying Russian C&C machines because they are just as good as German and Japanese models but are much cheaper.

    Precision in production has dramatically changed in the last few decades... just look at the early MiG-29s with the current ones... there are gaps in the skin of the early model MiGs you could poke your finger through... but at the time it was pointed out in the west but it didn't matter... surface airflows actually improve with rough surfaces... the dimples on a golf ball improve its flight range by creating turbulence at the surface so the the airflow follows the surface of the ball... a smooth golfball the air detaches at the edges so the full width of the ball creates drag and slows the ball in flight... a ball the same size and weight but with dimples even if that makes it slightly heavier means the airflow attaches to the surface and follows past the sides of the ball so the airflow drag volume area is reduced so hit with the same power a dimpled ball will travel quite a bit further with every shot.

    The rough surface of a MiG-29 probably didn't improve drag, but it certainly didn't make it worse as western experts suggested.

    At the time it made the planes quicker and easier and cheaper to make... now the skin of the aircraft is used for fuel tankage so the gaps would allow fuel to leak and would increase the RCS of the aircraft so new planes are much better made.
