The Ministry of Defense has decided on the date of acceptance into the Navy of a new minesweeper and a logistics support vessel

Two ships at once will become part of the Naval fleet Russia in the near future. The Ministry of Defense has decided on the date of raising the Andreevsky flag on the mine defense ship and the logistic support ship.

On August 20 of this year, the Severnaya Verf shipyard will host the solemn ceremony of raising the Andreevsky flag on the project 12700 Georgy Kurbatov mine defense ship and the Vsevolod Bobrov logistic support ship.

According to preliminary information, both ships will go to serve in the Black Sea Fleet. "Georgy Kurbatov" will join the 68th brigade of ships to guard the water area of ​​the Black Sea Fleet, and "Vsevolod Bobrov" will go to the home port of Sevastopol.

"Georgy Kurbatov" is the first serial minesweeper of Project 12700 "Alexandrite", laid down after the lead ship of the "Alexander Obukhov" series. The casting of the hull took place on February 26, 2015, and the official bookmark took place on April 24, 2015. The launch was scheduled for September 2017, but on June 7, 2016, a fire broke out on the ship, affecting about 600 sq. meters.

Vsevolod Bobrov is the second ice-class logistics support vessel. Laid down in 2013 and launched in 2016. There are some changes in the design, made according to the operating experience of the lead Elbrus. Length - 95 m, width - 22 m, draft - 9 m, speed - 18 knots, displacement - 9 tons, cruising range - 500 nautical miles, autonomy - about 5 days.

The vessel is multifunctional, designed for the carriage of goods, towing, carrying out hydrographic research, providing assistance to ships in distress. The ship's hull with ice class ARC4 allows breaking ice up to 0,6 m thick.

Why is a vessel with ice class ARC4 sent to the Black Sea?

Why is a vessel with ice class ARC4 sent to the Black Sea?

on the one hand, your question is natural.
on the other hand, do not build the Black Sea Fleet according to a separate project.

[Avior]

The ice class does not work out just like that, there are no miracles.
this is a deterioration in some characteristics due to the strengthening of the structure of the case and other things, this is an increase in price. And in light of this, the question is natural - for the Black Sea it is not an optimal option.

to the issue of price growth:
How much would a separate "Black Sea" project cost to the treasury?

[Avior]

Why separate the Black Sea? Baltic, Pacific ...
It is northern separately.
I think it's cheaper than building an ice-class ship for the south sea. It is more logical to supply air conditioners.

[Flooding]

Quote: Avior

You're kidding, I guess.
Icebreakers are in full swing in the Baltic.

[Avior]

Icebreakers work both in the Black and Azov seas. But the support vessel is not an icebreaker. He has a different purpose and different tasks.

[Flooding]

Quote: Avior

Icebreakers work both in the Black and Azov seas. But the support vessel is not an icebreaker. He has a different purpose and different tasks.

of course, the need for ice-class vessels is directly related to the ice situation in the water area.
you write, perhaps, about icebreaking ships for port services
and I'm writing about icebreaker escorting ships along the route
feel the difference

[Avior]

Sometimes it happens

The frozen Sea of ​​Azov holds 153 ships today. 65 of them took refuge in ports, 20 are trapped in ice in the sea, and 68 are in the southern part of the Kerch Strait. 19 vessels plan to withdraw icebreakers from the frozen Sea of ​​Azov to the Black Sea in the coming days. Food is delivered to sailors stuck in ice by helicopters. In the Caspian Sea, there is also a difficult ice situation; about 30 ships are waiting for icebreakers at the entrance to the Volga-Caspian Canal, the "Caucasian Knot" reports.

[Barberry25]

well, for example, if necessary, to transfer it through the NSR to the fleet where there is ice)

[Avior]

Ice is everywhere. But it does not mean that ice-class ships are being built for all seas.

[Barberry25]

universality has not been canceled .. it will be necessary to strengthen the grouping ... and what? to build new ships?

Ice at sea in the XNUMXth century
There is information when the Black Sea froze in the south. So, in 1953, the reservoir was covered with ice off the coast of the Crimea. That year, severe frosts completely hid the Sea of ​​Azov under the ice. There are references to such anomalies in ancient scriptures that have survived to this day. Freezing in the XNUMXst century
In 2012, in the regions of Crimea, Romania, Bulgaria, Odessa, everything froze. All maritime movements in these areas were suspended until 15 February. In that year, the thickness of the ice cover reached forty centimeters.

As in the Caspian

I've seen Aviora. But this does not mean that I generally understood what kind of incomprehensible member of the human community it was: either to the non-standard, or to the Denisovans, I have to attribute it ... in no other way.

Is the "ice class" ARC4 "something special"? Half a meter of ice (!!!) Oh horror! Does this require some kind of super-capability?
This is downright rise in price at times?
And if you count: WHAT will cost MORE: build ONE universal project (especially with the possibility of transferring to the Northern Fleet or Pacific Fleet), or build TWO different projects: one for the middle latitudes, one for the southern ones ...

[Avior]

... This is downright rise in price at times?

Have I written at times? This is a rise in the cost of production and operation.

And if you count: WHAT WILL COST MORE

As I understand it, you did not count anything ...

Interestingly, and WHAT did you "calculate" there? Can you share your "calculations"?

[Avior]

Arc4 - Independent navigation in thin one-year Arctic ice with a thickness of up to 0,6 m in winter-spring navigation and up to 0,8 m in summer-autumn navigation. Navigation in the channel behind the icebreaker in the first-year Arctic ice up to 0,7 m thick in winter-spring and up to 1,0 m in summer-autumn navigation.

Ice class for arctic seas.

[URAL72]

I think such ships are needed to supply our stations in Antarctica. The Black Sea is suitable for this - it is closer, has good year-round ports, infrastructure for the delivery of everything you need.

[seregin-s1]

Maybe the ship is more needed at the Black Sea Fleet now? It is not a fact that it will last a lifetime there.

[alex neym_2]

Do not think that the northern coast of the Black Sea does not freeze: how! (Of course, not every year, but it happens quite often) Yes, and Azov drives ice through the Kerch Strait. So there will be enough work for him ... for every "fire" case it will not hurt

[Sergey39]

Today at the Black Sea Fleet, and tomorrow it may be at the Northern Fleet or the Pacific Fleet.

[Xnumx vis]

So the Black Sea freezes in winter. With the exception of the South Coast and Sevastopol, all ports from Odessa to Novorossiysk are frozen.

[Turist1996]

At the very least, there is a practice of inter-fleet transitions and the use of ships from one fleet in a completely different theater of operations.
Therefore, I do not see anything wrong with the presence of an ice class for a ship, even for the Black Sea Fleet.
It may be more expensive, but for the operation of the crew - less troubles.

[Captain45]

Quote from AUL

And that there is no ice on the Black Sea? I remember about two years ago in winter on the coast of Crimea there were almost icebergs, and the Azovskoye field was so completely frozen. Let not for long, but the fact of the formation of ice took place, so according to the principle - and so it was!

[egor1712]

This is wonderful

[Avior]

... "Georgy Kurbatov" is the first serial minesweeper of Project 12700 "Alexandrite"

The situation with minesweepers clearly looks - similar minesweepers of approximately the same level are now being removed from service by the British and sold, replacing them with ultra-modern unmanned ones.
It is not clear only what devices for searching for mines are worth, since special military devices for searching for mines were under sanctions, and French vehicles for civilian use were forced to be installed on the first buildings of 12700, they did not fall under the sanctions. And now I wonder how things are?

[Flooding]

give an example please
modern unmanned mine action vessels are essentially boats that do not know how to operate autonomously and at a great distance
how can they replace, for example, the Alexandrite minesweeper?
they can only complement each other

[Avior]

what you write is a small boat, inspectors. We are talking about autonomous systems equipped with mine search devices, generally based on base ships. Such systems are now in development in England, France and other countries.

The British Navy has formed a concept for the further development of mine action forces. The main emphasis in the mine action is on robotic mine action systems, and the construction of larger and faster modular carrier ships is planned for their delivery.

Under the program "Mine countermeasures, hydrographic and patrol ships" (MNRS - Mine Countermeasures, Hydrographic, Patrol Capability), it is planned to build ships of a new project to replace mine countermeasures ships, hydrographic ships and patrol boats. As one of the options for this project, the Navy command is considering a ship 90 m long, with a hull made of steel, having a speed of 18-24 knots and the possibility of placing 16-21 weapons modules on board. The possibility of making these modules in the dimensions of standard containers is not excluded. This option provides for the construction of eight ships for the conduct of mine action operations.

It was originally planned that the new ships will begin to enter the Navy from 2023, but it was decided to revise these terms and go along a less risky path, namely, first to check the operability and reliability of the developed anti-mine systems based on existing anti-mine ships.

To equip the ships, it is planned to create 11 large and six small-sized mine action systems. The large mine action system includes an unmanned boat that transports various types of mine action vehicles to the border of a mine-hazardous area, as well as ensures their launch and reception. The small-sized system will include an unmanned boat of a smaller displacement, capable of carrying a towed GAS, as well as reconnaissance aircraft and devices for the destruction of mines. These systems (two) can be deployed, including on frigates of the "Aquitaine" type; one large one can be installed on the landing ship.

The concept of a carrier ship is being studied - in the form of a catamaran. Its design combines the advantages of a higher, in comparison with the Eridan-type TSCHM, speed and an increased area of ​​the aft part of the main deck for launching and re-receiving large unmanned surface ships. It is assumed that carrier ships of this design will make it possible to transport up to three large and several small-sized anti-mine systems.

Small unmanned boats were tested in the framework of the Safari program jointly with the Science and Technology Department of the Ministry of Defense of Singapore.

As part of the implementation of the SLAM-F concept in 2009, the main weapons department and the companies DCNS, Thales and ESA signed a contract worth 38 million dollars, which provides for work under the ESPADON program. Its main tasks are: to check the capabilities of automatic launch and reception of an APU and a towed GAS from a large unmanned boat; to establish the boundaries of the conditions under which it is still possible to automatically carry out this operation; check communication and control systems at long range. DCNS, acting as the lead contractor, is responsible for the creation of the unmanned boat and interaction with the base ship. "Thales" is responsible for equipping an unmanned spacecraft with PMO systems, creating a hydroacoustic module, which includes APA and GAS, and communication facilities between various components of the mine action system. ESA designs and develops autonomous underwater vehicles, a system for launching and re-receiving them and a remote control system for an unmanned boat.

By order of DCNS, Pech'Alu International shipyard has built the Strerenn Du unmanned catamaran boat, which was handed over to the customer in 2010. It has an aluminum hull and is powered by two water jet diesel engines. Its displacement with a length of 17 m and a width of 7,5 m is about 25 tons. The boat can be controlled remotely or by a small crew, therefore it has a cabin.

The catamaran boat "Sterren Doo" is equipped with a DUBM-44 towed synthetic aperture GAS and several types of autonomous underwater vehicles. APA type DCL (modification of one of the devices developed by ECA) is designed to detect, classify and determine the coordinates of mines, type I device (APA "Alistair 18 Twin", developed by ECA) - for identification of mines. For the destruction of mines, it is possible to use the K-STER apparatus (of the same company).

"Alexandrite" and serves as such a base, among other things
what then do you think the British write off?

[Avior]

no, it does not serve as such a base

The large mine action system includes an unmanned boat that transports various types of mine action vehicles to the border of a mine-hazardous area, as well as ensures their launch and reception.

these are unmanned boats that will be used instead of the Alexandrite or English minesweepers.

write nonsense without thinking
the boat itself needs basing
it needs to be delivered to the specified area
it has limited autonomy and is controlled just from a carrier of a much larger displacement
all the best. I think further discussion is meaningless.

[Avior]

obviously you just haven't seen them.
This is a small boat that performs auxiliary functions on a minesweeper and without a minesweeper is not capable of independently searching for and destroying mines.

This boat, 12700 ahead.

Able to take pictures using a submersible sonar, clarifying some nuances or getting additional information about the alleged mine.
But the Russian boats-inspectors Skanda developed instead of the French ones based on BL-680 boats.

These are just auxiliary devices for the minesweeper.
The British and French have a completely different thing - there are full-fledged minesweepers without a crew. they carry on board devices for the search and destruction of mines, that is, they perform the same functions as a completely minesweeper.
Read again the composition of the equipment of the new generation of unmanned minesweepers and compare with the boats-inspectors.

The catamaran boat "Sterren Doo" is equipped with a DUBM-44 towed synthetic aperture GAS and several types of autonomous underwater vehicles. APA type DCL (modification of one of the devices developed by ECA) is designed to detect, classify and determine the coordinates of mines, type I device (APA "Alistair 18 Twin", developed by ECA) - for identification of mines. For the destruction of mines, it is possible to use the K-STER apparatus (of the same company).

each of them is actually a full-fledged minesweeper, fully capable of detecting a mine in unmanned form, clarifying its type and confirming the identification, as well as carrying out its destruction.

Here are wonderful people: they argue whether an ice-class ship is needed in the Black Sea, but its main property - an auxiliary one - has been forgotten. It seems to me, gentlemen, that a serious turmoil may begin in the fall, for further time in Skakuasia will work against us. Arguments and counterarguments are listed many times. We will not deprive the outskirts of the coast - we will regret it.
