The decision on the fate of the second three frigates of the project 11356 has not yet been made

The fate of the second three patrol ships of the 11356 project, destined for the Black Sea Fleet, has not yet been resolved, although Rosoboronexport’s negotiations on the supply of these ships to third countries are known, reports RIA News message from the Vice-President of the United Shipbuilding Corporation Igor Ponomarev.

The Trikand frigate of the 11356 project, built by the Yantar plant for the Indian Navy, 2013.

Earlier in the "Rosoboronexport" stated that negotiations "on the supply of an additional party and the subsequent licensed production of frigates of the project 11356" are conducted with India. It was noted that the Indian fleet "already has six Talwar frigates, predecessors of the 11356 project, designed for export."

“The ships of the second three are built at the Baltic shipbuilding plant" Yantar "in accordance with the state defense order. The decision to transfer these ships to third countries has not yet been finally made. Although it is known that such negotiations are conducted by Rosoboronexport, ”

said the corporation's vice president.

Recall that the construction of these ships was suspended due to the refusal of Ukraine to supply gas turbine power plants.

If it were my will, I would build such ships instead of corvettes.
A lot of. With shells instead of the AK-630. Pieces of 9-12 for each fleet.
A 22350 displacement should be increased by 1000-1500 tons and something like Rif-M ++ set. Then there will be a normal escort ship.

[Berkut24]

Firstly, the project is far from the newest and most relevant in itself. Already written many times. They are building exclusively for the Black Sea Fleet and not from a good life, but it seems that the replacement has already taken place.
Secondly, adaptation of the "Shell" to sea conditions has not been completed. There are no test results and it is not known when they will be. And the ships are needed the day before yesterday.
And to increase the displacement of 22350 at a time when the project is not only approved and not only built, but has already been launched for testing - this is generally out of the realm of fantasy and means a complete redesign of the project "for expensive" and within 3 years at least. In my opinion, project 22350 is already quite balanced, the only thing that can be corrected is the ship's rather weak air defense system.

[Alex777]

As for the Armor, the topic is a separate, interesting one. The manufacturer is simultaneously "numb" and makes a hypersonic missile defense system. The SAM is interesting and, if successful, will give a revolutionary breakthrough. The firing range is 40 km. Maneuvering in the final section of the trajectory using the second stage engine. The current Carapace has only a booster engine.
The main drawback of 22350 in my opinion is the range. For an escort ship, you need 6000 miles with at least 18 knots. IMHO if on a fuel frigate for 2 helicopter flights - then why is this helicopter needed at all? So here the supply of volume also does not hurt.
Much more can be said about powerful generators, etc., but all this is lyrics. I’ll just attach one photo. Here and air defense corrected and much more ...

Well, if we consider the watchman from the point of view of an escort, then in a normal squadron there is always room for a tanker, and a helicopter is so that the summarians are afraid

and + beyond-the-horizon control center is not bad channel.

[Berkut24]

The main drawback of 22350 in my opinion is the range.

If we talk about using 22350 as an escort ship, you first need to decide who and what he will escort. The decision on the creation of aircraft carriers will be made when project 22350 is already completed in a series, and when / if the first aircraft carrier is built, then 22350 will already be an old man.
In general, there is a tendency in which the largest ships in the fleet - be it the Orlan or the future Leader - are being made self-sufficient floating arsenals with virtually unlimited range. Those. our concept has some differences from the American one, where the escort covers the "floating airfield", without which the squadron loses its range and becomes almost useless in solving its usual tasks. Here the leader of the group can stand up for himself and cover the escort. In this case, the group's armament allows you to "reach" the target without approaching the shore.
At the same time, we should not forget that supply ships and tankers that are already launching should be part of our compound. Those. 22350 in the group will have a completely different range.
To date, 22350 is still in fact a coastal defense ship and the range for this purpose is sufficient. The ocean fleet must be different. That is why the Ministry of Defense is inclined towards the gradual transition of large ships to nuclear power plants, so that the entire connection of ships does not have problems with this very range.

Too expensive for this role. And they built it like an escort.
And for the defense of the coastal zone 11356 is enough. And it’s 2 times cheaper.

[silver_roman]

Leaders are not planned to have as Berkov under 80 pieces.
Besides, it seems to me that we don’t really need an aircraft carrier. I am sure that Amer’s AUGs can be drowned without much difficulty. Another thing is that this does not happen for subjective reasons.
We have complex coastal areas, estuaries of many rivers, we need boats of the coastal zone. So we will never get away from RTOs. Another thing is that 11356 are not needed, just 22350 have not yet been finished.

As far as I know, the domestic GSU is undergoing tests now, which shows better characteristics than the Ukrainian counterpart. But on the GSI, the correction of shortcomings and refinement takes time.

[Denis Obukhov]

Well I do not know. The engines will be ready for delivery to frigates in 2018, maybe in 2019. You can wait a couple of years, even if the frigates are not of the 22350 Gorshkov level, nevertheless, they are worthy ships with anti-aircraft missiles, anti-aircraft missiles, and anti-ship missiles.
Do we have a surplus of new ships?

Most likely, this will not end there. We must either make a copy of the Ukrainian turbine, or remake the ship under ours.

Replacing one power plant with another is at least a quarter of the ship to do again. Any engineer will confirm.

No.

Establish M90FR. Plus, there are different others in the work afterburners turbines of lesser / greater power.

11356 operates on a scheme of 2 marching turbines + 2 afterburners.
22350 operates on a scheme of 2 marching diesel engines + 2 afterburner turbines.

If the afterburners can still be replaced (it is difficult at Butakov), having worked nicely with files and digested the bases. So there are no marching and will not be in the foreseeable future. Moreover, marching there need certain.

Total options:
1) Sell India.
2) Convert the ships under the scheme of 2 mid-flight diesel engines + 2 afterburner turbines. This will affect the running, price and timing.
3) Dismantle the hull to Borodin and Fog. The truth is where to put the ordered equipment, the question. The same Styles, Frigates, BIOs, etc.

[Berkut24]

The technical level of what Zorya Mashproekt supplied us is the solutions of the late 70s of the last century. There was only one reason to buy this equipment - cheapness. On the one hand, it saved money when building the ship. On the other hand, the cheapness and sophistication of not the most advanced design completely killed the desire to design something of their own. As a result, the country with the longest maritime border did not produce engines for its ships.
Once it had to be changed. And I am convinced that a solution will be found. For solutions for new aircraft engines have appeared, which means that there is already engineering and production potential on the topic. This stage once had to go through. Ukraine straightened our brains. Now she will find a competitor in another niche. Like helicopter engines.

[Xnumx vis]

Buy engines through third or fifth parties and deliver. After the revolution, tanks were bought and brought under the guise of tractors. As well as other equipment. Airplanes, engines Steam locomotives. Forgotten how to conduct secret operations. But they learned to hide money offshore. Thief!

[Orionvit]

Yes, do not worry about the power plants. Russia will get out. Here in the USSR they built everything from scratch, and nothing, they managed, even plugged the west into the belt.

The ship at the berth will become obsolete morally and physically.

[Wiruz]

So it’s not like waiting a long time, in 2018 they promise to establish mass production of ship engines.
To me, frigates pr.11356, to be honest, they are not pretty at all, but it’s better to leave them to yourself rather than sell them, since pr.22350 is difficult

[g1v2]

There is only one but. The production of only afterburning GTE M90FR, which are on both series of frigates, is being established. But nothing is heard about the development of marching gas turbines. Donavia has already explained something, but let me remind you.
On frigates 22350 there are CODAG type power plants - that is, 10D49 marching diesel engines plus M90FR afterburners.
On frigates 11356 there are COGAG type power plants - that is, marching gas turbines plus afterburning gas turbines M90FR.
The production of afterburning GTE M90FR is being established and by 2018 they will obviously be. PM frigates 22350 will be gradually equipped with them.
But what they cannot do with the second triple 11356. They were laid, because they were worked out and they could be quickly built, which is evident from the first three, which will be all commissioned this year, since Makarov is the third of it. For the second three, you need 3 pairs of marching gtu, that is, only 6 pieces. To deploy production for the sake of 6 pieces is in no way profitable, since after that it will need to be minimized. You can wait for the Ukrainians to give them away for a long time. The option is to sell the ships to the Indians, everyone is happy, because Ukraine is ready to sell the GTD to the Indians, but the Indians are aware of the situation and seem to be trying to bring down the price.
There is another option - to redesign for a diesel engine, but this is also very long. And the fourth ship of the Admiral Butakov series has also been launched.
That’s been decided for two years. There is of course an option still in my opinion - still make ukrov give the gas turbine engine, blackmailing them with something. In general, of course, much here depends on the hands of the enterprise. The Cossacks do not take a steam bath and sell us helicopter engines, bypassing the prohibitions. But nikolayevets so do not want.

[kepmor]

Damn, why are we in Russia used to doing everything through the tremendous ... opu?
There is also excellent experience in operating gas turbine ships in the USSR - projects 61,1135,1134B, 1155!
Indeed, in terms of motor resources and ease of maintenance equal to GTU, nothing has been invented yet!
Just compare the service life of ships with GTU and other engines! Heaven and earth, as they say! Neither "locomotives", nor a diesel engine, and "were not near"!
He himself commanded the IPC 1124, where there was a mixed scheme - the marching M-507 diesel engines and the turbine! And at sea he always tried to walk more under the turbine than on diesel engines, they were very moody in service.
One drawback of our turbines - they took a lot of hodgepodge, it is a fact!
Our diesels, that the main ones, that the auxiliary ones are just "hell" for the mechanics!
Well, we can’t make high-quality ship diesels like the Germans, Swedes or Japanese, there isn’t that technological culture, just not!
Our Kolomenskoe to "sultzer", as to Shanghai on foot ... and by the motor resource, and by the consumption of the hodgepodge and by the control system. It's a shame, but it's a fact!
Yes, they are now promoting the 10D49 diesel engine in full, they say, its prototype has proven itself well on locomotives, but the fact of the matter is that ship diesel engines are more complicated than locomotive ones and the conditions and loads are completely different. And they really haven't been tested on ships yet, because. the same "Gorshkov" covered a maximum of about 10000 miles - for statistics it is pshyk!
And our shipbuilders, let's copy the Germans, put a mixed scheme. Only before it was necessary to learn how to make the same diesel engine with gas ducts, and to train sailors in proper operation, and to create a service department in the fleets, as the Germans did all this!
Back in Soviet times, the "industry" themselves admitted that a mixed layout of the main engines was an unfortunate decision - you need cleanly or diesel engines or turbines! Then the ship will serve for a long time!

These ships were modern at the beginning of the 2000's, they are being built now not from a good life, but to plug yawning holes in the fleet over surface ships!
When I was studying at one of the naval institutes in those days, I wrote my thesis on the Talvar project, a special question was on the control systems of the power plant - then yes, it was almost fantastic - everything is automated, everywhere monitors ... domestic ships seemed like steam battleships of the Tsushima times in comparison with these frigates, and it was terribly insulting that all this beauty was for the Indians ...

Really competent thought, colleague. Unfortunately, in this situation, waiting will in no way increase the combat effectiveness of our fleet. And a simple warble at the mooring wall, in an unfinished state, only exacerbates the situation.

[alexmach]

Will become obsolete. But what do you offer? Sell ​​the Hindus? First, damage to the image. Secondly, nonetheless there should be non-import equipment, it is not clear what scope of work needs to be done to prepare it for sale. Thirdly, the Indians, knowing the situation, will surely twist their hands to the fullest.

We can’t finish building, and it’s not clear whether we can.

There is only one way out, it is worth it to preserve and eat. Perhaps a solution will appear. Relations may improve, even if not with the whole of Ukraine, well, at least with its part. Maybe they will become unnecessary - it will be possible to sell ... or to cut ...

The ship is certainly not new, but there is a nuance. 22350 are still not accepted for service. How successful they will be in operation, and what their real combat characteristics will be, is not yet clear. Suddenly Polen-Redoubt will not fly up, what will happen to the power plant? And with seaworthiness?

We will bake like pies 22350 - we will write off these - sell. So far, the prospects for 22350 are not very clear.

[Banishing liberoids]

There are two options - to leave Russia, and wait for the appearance of diesel engines for them, or buy turbines or diesel engines through third countries, put them on the boxes and use them for their intended purpose - that is, let them serve Russia.

I agree with you. If you do not have your own turbines, then, as a temporary measure, the purchase of Chinese will come down.

the purchase of the Chinese will do.

China is direct Greece, in which there is everything!
When will Russia come at least to the level of Greece?
Over 25 years have passed since there was no Union, and during that time no one was bothered by the question that Russia was paying someone jobs abroad, so that our ships would go.

[Phosgene]

Greece is not Greece and Chinese engines in terms of resources are worse than ours, but since domestic turbines are not yet ready, we need to buy Chinese ones, since the Russian government, out of great mind, did not timely launch their release in the Russian Federation

Firstly, in the 90s and 2000s it was not before. In fact, nothing was built, unless developed.
Secondly, Kudrin persuaded everyone to hide the money "in a box". And Ukraine also lived well from engine sales. No one had ever thought of such a turn of events. The localization of critical industries was started relatively recently, elementary did not have time before the events of 2014.
Somehow you want everything at once. There is no such thing. And so at the limit of opportunity, everything is updated. The United States generally counts on disrupting the modernization of our armed forces in the face of sanctions.

The USA did not give consent ... But Glonass-K compared with Glonass-M is heaven and earth ... A completely different level.

[okroshka79]

Who was responsible for the puncture with turbines and diesels? Apparently, nobody. In general, everything has been going towards this for a long time. More precisely, in my understanding, it was essno, when the ordering departments and research institutes of the Navy began to recruit, with the beginning of perestroika, not the best specialists from all fleets and they had to wait for an apartment for about 3 years, and Muscovites who had served in the Navy before. Because housing in Moscow and St. Petersburg had already become very expensive and the fleet did not buy it. I know of cases when such "dubars" came to the positions that determined the direction of development in the military and in the navy after serving in naval warehouses! I talked to them at Bolshoy Komsomolsk (now Zlatoust)! And then these were dispersed. The optimization was accomplished and the girls came with their feet from their teeth ... Now the fleet has become without any intelligible management and a clear ordering system. Sadly, all this. Indeed, one involuntarily thinks that Stalin with his pipe is oh so needed.

[mr.redpartizan]

It is unfortunate that the frigates 22350 decided to put diesels as marching engines, and not gas turbine engines. It is necessary to develop the technology of ship electric transmissions, similar to those installed on the British destroyers Type 45 or American Zamvolte. Or even abandon the division into marching and afterburning gas turbine engines by installing four gas turbines as on Arly Burke-type destroyers. It is a pity that we do not have turbines like the American GE LM2500.

[Wiruz]

The electric motor on the warship is essentially not needed, their efficiency is much lower. They are placed only when there is a great need for electric energy. On all kinds of yachts, cruise liners, etc. They were installed at Zamvolt only because of future railguns.

Everything is so .. there is one BUT. Where does the electric motor get lipids? Probably from an external source, which has its own efficiency. Usually a diesel engine .. ..therefore, from its 50%, it is also necessary to take away losses in power transmission. Although, speaking generally, the diesel efficiency can reach 70%, but in a narrow range of rotational speeds. Such diesel engines are called sustainers, they work well in a narrow range and rotate the generator in this range. However, this is not an option for a warship.

Everything is so .. there is one BUT. Where does the electric motor get lipids? Probably from an external source, which has its own efficiency. Usually a diesel engine .. after all, from its 50%, losses in power transmission must also be taken away

Losses in energy transfer through internal networks are minimal of the order of 0,2%, but take the losses on the gearbox, the load on the shafts, and the fact that the location of the motor-reducer-screw system is not unimportant. But the system with an electric motor allows you to get away from the classical scheme layout, cross out the gearbox, transmission shafts, reduce weight and naturally reduce losses!

[Grigory_78]

Is logical. The efficiency of the gearbox can be taken approximately 0,9-0,95. That is - 5-10% of losses, which is definitely more than losses on internal networks under normal conditions. The question will be about the security of internal networks. It would be interesting to know the probability of an increase in losses during operation. Also, their dependence on temperature. In principle, the decision is reasonable. With BBM came to this. In ships, such decisions are also obvious.

[mr.redpartizan]

It is not clear what to do now with the three ships already built. What to do in case of malfunctioning of marching gas turbine engines as a result of the end of their resource? Namely, on these engines the ship goes most of the time. There is no answer to this question yet. It would be worth considering the transfer of the first three ships to the Indians, especially since they are more powerful than the export type Talwar. We need to focus on the production of more advanced frigates of project 22350 / 22350M and accelerate the development of destroyers like Leader with nuclear power plants for us and gas turbine engines for export.

Blessed is he who believes. You can put one or two Stalin, three-five of Beria, to shoot several dozen of those who are at the head of the shipbuilding industry, but that would not change anything. The belief that Stalin would have been at the helm is only faith and nostalgia. If not PRODUCTION - be even a dozen Stalin-nothing will change.
They may object to me that it was necessary to think, to establish production at home, etc. Yes, it was necessary to establish, but do not forget one. It was necessary to resolve the issue not only in this one industry, but in all. For the collapse of the Union is not only the division of the state into several states, it is also the collapse of cooperation, horizontal and vertical ties. And there it was all the same: wherever you throw - everywhere a wedge. Therefore, they began first of all with the area that was most important - with nuclear missile forces. What next. Do not forget that we and crises did not pass. In some areas, in some

Although comrade rudolff is right, he had to move more actively

Quote: Old26

The belief that Stalin would have been at the helm is only faith and nostalgia. If there is no PRODUCTION - be even a dozen Stalin - nothing will change

I strongly apologize. Where was the USSR industry at the time of Stalin's rise to power and where was the USSR industry at the time of Stalin's death? You somehow strangely divided industry and Vissarionycha, although they were very much interconnected

[mr.redpartizan]

That's it. Stalin came to power in the mid-20s and by the beginning of the Second World War the USSR already had a fairly powerful industry and science, without which we could not have won. And this is in the face of severe sanctions, famine, devastation after the civil war, mass illiteracy among adults. Yes, all the power of the state machine was used to force those who disagree, it was not without the use of forced labor, purges among managers, but the task was completed.

What are these sanctions? America sold us everything we needed: tractors, steam locomotives, machine tools. Even built factories and power plants on a turn-key basis.

I will supplement the question:

- by whom and due to what factories under Stalin were produced-built-launched?

Here are a couple of examples, if you want, you can find a lot more:

In May 1929, The New York Times reported that the architect Albert Kahn, the Soviet foreign trade organization Amtorg, proposed a $ 40 million contract for the design of several tractor plants. The United States at that time was on the verge of a powerful financial crisis - the Great Depression. Therefore, the offer from distant Russia for Kahn became more than tempting ... The first Kahn plant in the USSR - the Stalingrad Tractor - was designed and built in America. Then it was disassembled and, together with the equipment on 100 ships, delivered to the customer. The enterprise was an exact copy of the Caterpillar tractor plant, just like the Gorky Automobile Plant, also designed by Kahn, was a copy of the Ford auto company

And now we are thinking - will the American "partners" agree now in the current environment on similar feats? IMHO is unlikely

[voyaka uh]

Detroit firm Albert Kahn (Kogana) designed and built on a turnkey basis
more than 500 factories in the USSR, including all key factories of the military-industrial complex,
... factories of the aviation industry, automobile industry, engines.

do not worry so everything will be!

put yaeu and not bother ,

[mr.redpartizan]

Firstly, a major restructuring of the project will be required for conversion to a nuclear power plant, and secondly, the displacement of the ship is too small, which makes it difficult or even impossible to make an atomic conversion.

[ZAV69]

Most likely difficulties in operation and other risks, frigates are now the main plowmen of war. Almost everyone will die. To write down losses in small local wars, ships with a nuclear installation seem to have decided that it is very cool. As for the dimensions, power plants based on tractors were also developed in the 60s, was there a huge reactor?
Really make a small ship. Just risks, time, costs, it’s easier to screw a gas turbine

[mr.redpartizan]

The tractors had a mobile power station with a capacity of only a few megawatts. For the movement of a frigate-type ship, a shaft power of tens of thousands of horsepower is required, and this is TENS of megawatts. For example, Borey-type submarines are equipped with an OK-650V reactor with a thermal power of 190 MW, which makes it possible to output 50000 hp on the shaft. A nuclear power plant of such power weighs hundreds of tons, because for the operation of the reactor, circulation pumps, steam generators, GTZA, many different automation systems and reliable biological protection from radiation are required.

[Rambylbafen]

please remember the displacement of pr. 705, yes it’s flat, but they pushed it in and it turned out well , and modern water-water in size is not much and larger (this is together with the GTZ) you just need to set the task, profile designers, layout in place in a given volume.

[mr.redpartizan]

Submarines of project 705 were originally designed for a reactor with a liquid metal coolant, which is several times smaller than water-water. The reactor requires a mass of other equipment, under which it is necessary to find a place on the ship. A nuclear power plant is advantageous on ships of large displacement, for example, on aircraft carriers and heavy missile cruisers. A gas turbine power plant is several times smaller than a nuclear power plant with the same mechanical power, because in it the energy of combustion of fuel is directly converted into mechanical energy without loss of conversion of heat into energy of expansion of steam.

[Rambylbafen]

I just gave you an example of the use of nuclear power plants in about the same displacement, you can still see the evolution of the 671 project (in the sense of their nuclear power from GTZ) and this was all in the last century in 60-70 years so there’s no need to radically change the project itself, but you need to modify existing projects for the project and, among other things, the displacement can even be reduced with the removal of fuel tanks

[Rambylbafen]

The nuclear power plant (together with the gas turbine engine) occupies less volume than gas-turbine or steam-power plants !!! And if you still take into account: autonomy, released volume (fuel), efficiency (time increase or decrease in power) and the range is unlimited (only by the food supply and the psyche of the crew)

What are these sanctions during the reign of Stalin?
America sold us everything we needed: tractors, steam locomotives, machine tools. Even built factories and power plants on a turn-key basis. For example, have you heard anything about Armand Hammer?

I want to fly to the moon and what. Who will serve them? For rent, yes, we rent to Indians, but the responsibility lies with us. Do they have nuclear reactor maintenance specialists? No, but no and there are no nuclear ships and is not expected

If we are talking only about these three frigates, then such a solution is possible -
Snake >> now China itself produces an analogue of the Zorevsky UGT-25000

If China stamps them as famously as destroyers, then why not make them an offer they cannot refuse?

The fate of the second three patrol ships of the 11356 project, intended for the Black Sea Fleet, has not yet been decided, although Rosoboronexport is aware of negotiations on the supply of these ships to third countries, RIA Novosti reports.

No money left! But you hold on there! And good mood in honor of the day of the Navy!

So what is this "news" to interpret?

And a song in the subject:

[Santor]

Quote: 30 vis

Buy engines through third or fifth parties and deliver. After the revolution, tanks were bought and brought under the guise of tractors. As well as other equipment. Airplanes, engines Steam locomotives. Forgotten how to conduct secret operations. But they learned to hide money offshore. Thief!

Sci-fi read well respected? There, in those 30 years, everyone knew everything and looked through their fingers, since they themselves sold not only the latest weapons to Stalin, but also turnkey entire plants.

If you think that there are fuckers in the intelligence of other countries, then your site is "Russian Spring" .... Everything is closely monitored, and no one will go for it. As an example - attempts by Ukraine and its owners to buy ammunition as well as military equipment, including tanks in third or fourth countries. Ve was detained on the "CHOP-UNGENY" line

Quote: okroshka79

Who was responsible for the puncture with turbines and diesels? Apparently, no one. In general, everything has already been going towards this for quite some time. More precisely, in my understanding, it was essential when, at the beginning of perestroika, the ordering departments and research institutes of the Navy began to recruit not the best specialists from all fleets and they had to wait for the apartment for about 3 of the year, but Muscovites who had served in the Navy before. Because housing in Moscow and St. Petersburg has already become very expensive and the fleet did not buy it.

Does it mean that ..... they didn’t have a phone in the kitchen on time? Or do you think that tyap-blooper and the plant is built? Bloopers and engines designed ... Aw ....

The construction of the factories began in 2011, it was simply not advertised, like much that was done in Russia, and which turned out to be an unpleasant surprise for the "partners".

And a surprise for the Russian population, which is still sacredly waiting for when they condemn Serdyukov and put Vasilyev .... well, well ...

There is no puncture .... It just takes a year or two to develop an engine ...

The frigates "Yantar" in fact do not meet the latest modern requirements, but there was no way out, since the series had already been worked out on the Indian order.

Work on them continues, every day I drive by .... If the issue of transferring to India is resolved, the American company General Dynamics is ready to supply the propulsion systems, already spinning around the Indians wagging its tail ...

While the issue of transfer is not resolved .... Rybinsk began production of engines under the Chinese license, but so far only for small ships. Its developed, but brought and tested ... Time, time and time again ....

You do not need to consider Putin and his entourage as suckers .... But in fact, what you wrote is what turns out ...

We have a minimum of information, often distorted or deliberately misinformation .... And on this basis, as well as on the lyrics of various bloggers, we judge what is happening ....

Cool gentlemen, everything is under control, but not so simple. For over the years of the rule of the females of the liberals, almost everything was ruined, not just the army.

And now it’s not necessary to restore anything, but to do everything from scratch ... Since building a new one is cheaper than upgrading the old one.

Cool down.
