On the Middle Nevsky Shipyard, the formation of the eighth Alexandrite Corps began

At the Sredne-Nevsky shipyard, the formation of the hull of the new Alexandrite project 12700 mine defense ship has begun. According to the press service of the enterprise, the ceremony of laying the new minesweeper will be held on July 24, 2020.

The shipbuilders of the Middle Nevsky Shipyard began forming the corps of the next minesweeper. In a hermetically mounted matrix, repeating the contours of the hull of the future ship, under the influence of negative pressure, a binder is impregnated with specially laid layers of fiberglass. The impregnation process will take about two days.

The new ship will receive the name of Lev Davydovich Chernavin, a Soviet submarine officer, rear admiral who commanded the submarine formations of the North fleet. The Lev Chernavin will be the eighth ship in the line of project 12700 Alexandrite, laid down at the Sredne-Nevsky Shipyard and the last, built as part of the first series. Starting from the ninth, the minesweepers of this project will be built taking into account the changes made to the project during the operation of the first ships. Most changes will affect the automation of mine action.

Minesweepers of the 12700 project are able to use the latest hydroacoustic stations located both on the ship itself and on remote-controlled and autonomous underwater vehicles, and they have an automated mine action control system. Able to use traditional and traditional weapons. The ships of the Alexandrite series have a unique hull made of monolithic fiberglass, formed by vacuum infusion.

The 12700 project was developed by the Almaz Central Marine Design Bureau for the Russian Navy. These mine defense ships have a displacement of about 890 tons, the length is 62 meters and the width of 10 meters, the crew has 44 man.

Minesweepers need to saturate the fleet. I would just like to quickly.

Modern minesweepers ... not anyhow

Do you have something against Alexandrites? How did they displease you?

Do you have something against Alexandrites?

Only one thing, few of them, very few ... and it looks like there are no more capacities to produce them. And not only in the buildings, but also in the filling.
And to saturate the fleet, anyway with anything, if only it would be, as it would not be desirable

3 have already been built, another 5 are under construction. Not too bad.

Four fleets and a flotilla ... with many basing points ... not even funny

[g1v2]

Well, in theory, the Alexandrites should change all our minesweepers and they need about 40 pieces. The naval authorities spoke about this more than once. They will be built a couple of decades. Moreover, in series and in fact the series will gradually differ in the filling. Just like the alexandrites being built now with a filling and a crewless boat are different from the head Obukhov, the minesweepers, which will be laid in 5 years from now, will be different from those that are being built now. I think they will also go through time through several modernizations.
But in general, in peacetime after 3 years there will be a necessary minimum. In fact, we need them at the Black Sea Fleet, which is constantly located in areas of potential and real hot spots. Look, Ukrainians constantly mine the coast, and sooner or later they will begin to set the sea. According to their Navy, they still have about 2 thousand mines left. The Black Sea Fleet should be provided with alexandrites at least up to 5-6 pieces. In second place is the Pacific Fleet. And only then BF and SF.

Here, as they say without comment ...

I would argue, Pacific Fleet and Northern Fleet, or rather the Northern Fleet and Pacific Fleet, the second stage and the last BF. Do not forget that at the SF and Pacific Fleet our missile carriers, the exit and return of which must be well ensured

[g1v2]

For SF - this is a danger in the case of a large p ..... For BF too. There, besides NATO, we have no opponents. In addition, mining in the SF area is not too simple. In the Arctic, mine danger is much less, unless of course you put mines right at the exit from our bases. But such a case means a complete proser of all the services of the fleet and the aerospace forces; The main zone of NATO defense there is the Faroe-Icelandic border and it is intended not to let the Northern Fleet enter the Atlantic. That is, they will mine there.
Of course, in the event of a conflict with NATO, the Baltic will quickly become a "soup with dumplings", but the rest of the time the mine danger there is only from WWII mines.
Pacific Fleet is still in a more dangerous region. Japan is not a member of NATO, A CONFLICT WE HAVE WITH IT. And she has a claim to the islands. Plus, there are many passages between the islands where you can carry out mine operations. Again, setting up in Peter the Great Bay or Avachinsky is easier - it’s a stone's throw to the shores of a likely enemy and it’s easier to approach. The experience of mine productions in the Russo-Japanese war on this TVD showed their effectiveness. Well, in general, there are too many contradictions in the region. which can develop into a conflict even without our participation, but it’s all the same mine put on us, or it, for example, the Koreans put on each other.
Well, the Black Sea Fleet is without a doubt the main priority. By the way, in the films of Dergach it was said that before the Ukrainian drg in 16 tried to break into the Crimea, our group detained a group of 4 scuba divers. The 73rd center of naval special operations of the Ukrainian Navy has not gone anywhere. The swimmers can also perform staging.

Do you have information that we don’t have them?

Marina Raskova was accompanied by three minesweepers, this did not save her .... and three minesweepers on two oceans and three seas ... not enough like that .... the entire Russian Navy is not operational because there are only three minesweepers ... and how much is needed? Three for ships of the first rank (NPS), a pair for the second rank, and one for the third rank ... I don’t write about transports, so you need a large number of much-needed ships, but there are none, only three now and .. ...

[Alexey from Perm]

it's good that at least these do. What is enough for our resource-based economy is what they are doing.

[Shurik70]

At least the case is without metal, as is necessary for a modern minesweeper.

Something I can not click the "asterisk" to like the article ...

[Imperial Technocrat]

No gauges

[Doccor18]

Minesweepers are certainly needed. Yesterday ... And now, like air, we need unmanned mine-seekers-destroyers. Own production. And so that at least 2 pieces on each Alexandrite.

The Navy needs to be updated, well done!

[APASUS]

With this technology, the main emphasis is on the matrix, and then you can rivet at least one body per week. Only have time to cut and lay the fiber. It’s a completely different matter with the equipment for such ships. Do they allow the capacity to increase the production of equipment
Radar armament NRS "PAL-N"
Radio-electronic armament of the COP "Ruberoid",
PGAS "Anapa",
GAS ZS "Structure-35",
GISZ "Altyn-M"

[Alex 2020]

There was information that part of the search equipment was of foreign origin. In particular, towed and telecontrolled French trawls. Replaced by domestic equipment?

I think it is for this reason that ours did not demand compensation from the French for undelivered ships, but simply received the costs back. We had a lot of projects with the French on electronics

[Serpet]

What is there with Kurbatov? Will they hand over this year?

They will not surrender. After a fire, they still won’t even be allowed to enter the water. This year they will hand over Balyaev for the Pacific Fleet.

[Mountain shooter]

As far as I remember, the only warship of this size with a non-metallic hull. And for a minesweeper, such a hull - a great help - magnetic mines do not react.

[petrol cutter]

I watch him form an overkill (judging by the photo).
Interesting method. Only once did I encounter such a method on the edge of a small vessel (from AMg true). Honestly, such a construction technique seemed very troublesome and time-consuming to us.
How our craftsmen are burning - we are "Old Believers" and prefer the traditional method of building a ship / ship ("Comet" 120M - for example, which I have the honor of doing for a week now).
I beg your pardon, I got into the jungle. "Novinka" is engaged in plastic at our NW. Not strong in this matter. Perhaps it is more convenient for the ladies there / even most likely.
