    Exactly. If you are able to build nuclear subs there is no need for an AIP just to be able to travel for four weeks under water without surfacing. A longer duration with such small boats would be difficult = diesel subs are proven and more then good enough for patrols or even shooting cruise missiles at some terrorists.

    AIP is quieter than electric batteries and Reactors.

    Nuclear ships are also very expensive to maintain, why would you equip a submarine that is meant to serve has a brown water sub with overly expensive propulsion and powerplant it doesn't need?.

    Lada's aren't going to go deep in the Atlantic for months on end they do not need such a thing

    A kilo without aip will be just as silent as one with. Diesel subs use their diesel engines to recharge their batteries. Then run on batteries.

    AIP help improving the quantity of power stored or help produce electricity under the water like for exemple store oxygen so that the engines can work without the need to surface.

    In terms of accoustic the engine will still need to be turn on and that produce huge noise. Diesel subs are more stealthy than nuk only when running on batteries.

    No they are quieter, propulsion wise AIP is quieter.

    A kilo without AIP will be noisier than one without AIP.

    You added side information I never talked about.

    The process of generating electricity used by a hydrogen fuel cell is as quiet as a battery, but offers better energy storage than most batteries.

    New batteries and HFC or other similar fuel cell technology is quiet, but no matter how the energy is created or stored it runs an electric motor to actually move the sub.

    A Kilo class sub with a German hydrogen fuel cell and batteries will not be any quieter or louder than a Kilo class with batteries... because it will use the same electric motor for propulsion whether the power is coming from a fuel cell or a battery it is just as quiet.

    Not all AIP systems are quiet but all extend the time a sub can operate underwater.

    The new Megawatt NPP for powering lasers would be an excellent component to add to an existing SSK and could be used to charge batteries and operate the sub without needing to surface.

    In fact they could easily fit 2-3 of them in a Kilo sub replacing the diesel engine and diesel fuel tanks that would no longer be needed... they could be used like the diesel engine... each of which generated 1,000Kw, so most of the time they would be off with the sub operating on batteries and then when the batteries need a charge... no need to surface and snorkel... just turn on the two or three NPPs to fully charge the batteries while remaining fully underwater... in fact when you are chasing something you could turn on the NPPs for an extra energy boost to increase speed and endurance...

    Even if these NPPs were noisy when operating they wont be as noisy as two diesel engines and the fact that they don't need to surface makes them vastly more stealthy. You could drop them into the design like batteries themselves and swap them over just as easily.

    As technology improves the power they generate will increase, their size and weight will decrease and the costs will become cheaper and cheaper.

    Nobody has presented a case for AIP based on operation performance of diesel-electric submarines.    Small submarines were never designed to be in the water for
    years without surfacing.   So they were never used in such roles.    Now we have this AIP gimmick and all of the sudden no diesel-electric has any use without it.
    Utter BS.   But this gimmick-think is exactly how western marketing works.   Consumer saps think that they can't live without some new feature that has less than
    marginal impact on the utility of a product.    And western diesel-electric sub makers can then sell their boats for $2 billion each.    Would anyone please demonstrate
    how AIP justifies a 6-fold price markup compared to a project 636.3 submarine?

    Arming submarines with more effective weapons is not a gimmick.

    Dived performance was always crucial for submarines through history, and AIP gives marked improvement in autonomy when dived. When using fuel cells it is also completely quiet, as fuel cells do not have mowing parts. Nuclear propulsion gives practically unlimited underwater autonomy, but it is also the most expensive. So, russian navy needs a number of non-nuclear subs for operations in coastal waters. As pr.677 new type of battery gives something like 650NM dived on 3 knots, there is no substantial deficiencies in comparison with AIP. Consequently, it is good for Russia to work on an AIP powerplant, but there is no need to hurry, as there are so many other "holes to fill" in russian navy`s order of battle - decreasing number of modern and adequate ocean going surface escorts, for instance.
    Also, let western navies "blow off the roof" with devilishly expensive AIP - as this will lead to "impossibly low number of operational subs in western navies" - crippling in the end their combat capability to critical extent. Watch what happened wit swedish navy, for example. 20 years ago they had more than ten operational submarines, but now they have three or four, with no hope of increasing numbers. The increased capability of AIP subs does not merit two or threefold decrease in numbers of operational boats.

    Type 212 costs around 400 mio $ and Lada costed 300-350 mio in the end 1990s, because of inflation you can translate this into 450 mio today. You can drive the price down with scalling up the production. The entire Latin America drives German subs. I think the decrease in size of Russian navy has lead the Swedish navy to do the same.

    lol1 Rolling Eyes Embarassed How would inflation in USD increase the cost of Lada's sold in Rubles? Wink The Ruble circa 2019 has roughly 1/220th the value the Soviet Ruble had (circa 88'-89') during the time the Lada was conceptualized, and still has less value (albeit not as significant) than the Federations Ruble circa the late 1990's. The Ruble circa 1998 had 1/6th value of the USD of that year, and the Ruble circa 2019 has 1/70th value of the USD of 2019. Because they're are sold in Rubles it means that they will sell at the same value as export and generate more income, but the domestic prices can be negotiated privately.

    High Russian inflation would increase relative price of Lada even more and prove that AIP isn't that expensive. But inflation are only numbers. If you translate it in present Russian prices you can tell an ordinary Russian how many loafs of bread Lada buys, but that's all.

    If you prefer fair play, than translate today's 212 prices back to the end 1990s using German inflation: 400/(1,02)^20=270 mio. Much cheaper than Lada, not to say that in the time of those prices being set, 212 wasn't serially produced yet.

    You seem to of completely ignored the information in my original post, and selectively chose what to respond to. You brought up "High Russian Inflation" but you completely ignored the fact that the value of the Ruble circa 1998 was 1/6th the USD, and it's 1/70th the USD circa 2019, and yet you didn't see a massive hike in price did you? So explain to me why Lada prices haven't grown by a factor of 10???

    Because the inflation and the exchange rate effects offset each other Smile the exchange rate effect is static and the inflation rate effect is dynamic.

    If you live in Russia you only take into account inflation effect to capture the price dynamics from 1997-----> 2019 and translate old prices into new. What was worth 1 rub in 1997 is now worth 10 rub.

    If you live in the US you need to offset this inflation effect, which is not present in your country, by multiplying the new price with the new exchange rate, it is a static transformation in this moment in time to get you from Russian world to the US. Note that both effects perfectly offset each other. Russian inflation was averagely more than 10 % in the last 20 years, increasing prices tenfold, just as the exchange rate increased tenfold. So you get again exactly 0,15 USD for 1 rub in 2019 dollars as in 1997 dollars. But now you miss the dynamic effect of 22 years - the inflation rate. It's not representative to talk about 1997 prices in 2019 without adjusting them! So multiply with 1,5, the US inflation.

    Can anyone show an official price tag of Lada?

    By some reports a Yasen sub costs $500 million now that it's in production.

    I really do doubt that a Lada-class sub approaches that; possibly only the head of the series.

    Then they decided to heavily modernise 885M and Kazan costed 3.5 bn.

    You must be very careful when considering prices of "defence materiel" in Russia. Defence industry is exempt from NDS - VAT for products for domestic use. Material prices are lower than stockmarket prices and salaries are rather low - no more than 1.000$ for an engineer. Find an engineer in US who will work in defence industry for such a salary! They work for tenfold salary - and their results are ... rather not talking `bout that.

    Compared to the living costs they earn nearly the same. A small house in Amiland will cost you 500.000+. Your kid goes to college? 50.000+. A small band aid on the knee of your kid? 500+. A hamburger? 20+.

    MIT costs over $40,000 per year.

    The real reason for Russian military product prices being much lower is not the exchange rate or poverty, it is the lack of massive corruption like in the
    USA. The recent failure of the high speed rail project in California because the "ran out of money" is an example. Every contractor and the dozens
    of subcontractor associated with them all gouge the taxpayer for every last dime. American defense sector workers are not making tens of millions of
    dollars. The money goes to the owners and shareholders.

    Fourth Generation Conventional submarines
    15 Jan 2019
    Russia’s proposal for the Indian Navy

    http://www.vayuaerospace.in/article.html?n=fourth-generation-conventional-submarines&d=201

    The second Pr.677 conventional submarine (improved Lada-class), the Kronstadt, was launched in Russia at the Admiralty Shipyards in St. Petersburg on 20 September 2018, the submarine being a Kalibr cruise missile carrier. The highly accurate and destructive power of this weapon was recently demonstrated by the Russian Navy during “counter-terrorist operations”, and combined the lowest level of hydroacoustic field with high detection ranges for onboard sensors of the carrier.

    "It’s hard to overestimate the importance of this event. The submarine began to be built in 2005, and although there have been some pauses in financing and construction halts, this lag however has allowed us to use the experience gained in operating the (lead) submarine (of that class), the St.Petersburg. The Pr.677 underwater combatant outperforms its predecessor, the Pr. 636 (improved Kilo-class) diesel-electric submarine, in major manner. We believe that the Pr.677 will be future of the (Russian) Navy's diesel-electric underwater force and hope for a large series of the submarines (of that class)," stated Admiralty Shipyards CEO Alexander Buzakov during the ceremony.


    Kronstadt to fourth generation of the Russian non-nuclear boats. The Pr. 677 and its export derivative Amur 1650 are meant to supersede the Kilo-class. Lada is more compact: with similar weapons composition (six torpedo tubes with weapons comprising 18 torpedoes and missiles), standard displacement is reduced from 2350 (for Pr. 636) to 1765 tons. Because of increased automation, crew numbers are reduced from 52 to 35 personnel. The Lada is equipped with sonar with quasi-conformal large-area antennae and towed array sonar that considerably surpasses series-produced sonars on the earlier Pr. 636 submarines.

    Speaking at the ceremony during launch of the Kronstadt, Russian Admiral Viktor Chirkov said that due to their noise levels, the earlier Kilo-class submarines have been nicknamed ‘black hole’ by the western military. Trials of the new boats have demonstrated that their noise levels are several times (four or five, as per calculations of designers) lower than that of the Kilo-class. “Given that stealth of Lada-class submarines, which can be neither seen nor heard by the enemy, has increased, this submarine may be called an invisible creature,” he continued. “The new submarine enables us to make a step forward in developing state-of-the-art underwater fleet of Russia,” Viktor Chirkov summed up.

    The Amur 1650 on offer to India has AIP based on fuel cells and the electrochemical generator will covert diesel fuel to produce hydrogen. Rubin Design Bureau CEO Igor Vilnit had earlier expressed his assurance to the Indian Navy, who are anxious to integrate indigenously produced AIP on own ships, would be helped or assistance provided for their development.
    Lada-class submarines for the Russian Navy are also planned to be equipped with AIP developed by the Rubin Design Bureau. The Pr. 677 leading ship, St.Petersburg, is now in service with the Russian Northern Fleet and

    long-term sea trials conducted since the Russian Navy flag raising in 2010 have shown that submarines of this class are suitable for operations conditions of heavy traffic in the confined waters of the Baltic, as well as blue waters of the Barents Sea and the White Sea, with access to the North Atlantic. “St.Petersburg has not only proved its characteristics, but even outclassed them”, stated Igor Vilnit during launching ceremony of the Kronstadt.


    The Kronstadt is being built as an improved Pr.677 design, the same as the third Lada-class submarine Velikiye Luki which is presently under construction at the Admiralty Shipyards. Kronstadt and Velikiye Luki have radically improved their propulsion, engineering control and navigation systems. Igor Vilnit said: “Kronstadt is superior to previous submarines in all technical parameters. Moreover, we have taken into account all required modifications of the lead submarine. Most of the series production equipment, which has passed all tests and complies with the stated technical characteristics, is now installed onboard the Kronstadt”.

    The Kronstadt is planned to be commissioned in 2019 and the Velikiye Luki in 2021. According to the Russian State Armament programme, contracts for two more Pr. 677 submarines are to be issued by the Russian MoD during next year.


    As Deputy Chief of the Russian Navy Shipbuilding Department, Captain 1 Rank Mikhail Krasnopeev, remarked: “The entire history of Admiralty Shipyards, starting from time of Peter the Great, testifies that the company is able to build unique ships. And today’s launch is a vivid confirmation of this. For Russian sailors, it is an honour to serve on such modern submarines”. He also emphasised that the Russian Navy would continue to actively develop the non-nuclear component of its submarine force. “We’ll work further to improve and induct new technologies in the construction of non-nuclear submarines, to improve the parameters of stealth and effectiveness of its armament. Special attention is paid to the training of submarines’ crews, as they will be operating the most modern equipment”, he said.

    Second Yasen-class nuclear submarine on sea trials

    Russia’s improved Yasen-class submarine, Kazan, went for sea trials for the first time on 25 September, sailing out from Sevmash shipyard in Severodvinsk. Kazan is the second of the Yasen-class nuclear powered fast-attack submarines, but the first modernised vessel. The leading submarine of Project 885 Severodvinsk entered service on 17 June 2014, the next six ships in the series being built under improved Project 885M (Yasen-M), characterised by the optimised hull shape and upgraded electronic warfare and automation systems. Kazan was laid on 24 July 2009 and launched on 31 March 2017, is armed with Oniks and Kalibr cruise missiles. As per the Russian Ministry of Defence Spokesperson Yasen-class submarines have the capability to operate not only against ships but also to perform deterrence functions due to its missiles, stealth features and speed.
