The seventh minesweeper of the 12700 Alexandrite project was laid in St. Petersburg

In St. Petersburg, laid another ship mine defense (minesweeper) of the project 12700 "Alexandrite." The solemn ceremony of laying the ship was held at the Sredne-Nevsky Shipbuilding Plant.

The lead ship of the series "Alexander Obukhov"

A minesweeper laid on the Middle Nevsky GCC, dubbed “Anatoly Shlemov” in honor of Vice-Admiral Anatoly Fedorovich Shlemov (1949-2018), is the seventh ship of this type and the sixth serial after the head ship Alexander Obukhov.

Currently, the Russian Navy includes two minesweepers of Project 12700 - the lead ship of the Alexander Obukhov series, which became part of fleet in December 2016, and Ivan Antonov, transferred to the Russian Navy in January of this year. At the same time, "Ivan Antonov" is the second in the series after the first in the series minesweeper, "George Kurbatov." Kurbatov’s hull burned out almost completely due to a fire, so it had to be restored almost from scratch and the deadlines for shifting to the right were greatly shifted, passing the ship Anton Ivanov forward.

Another minesweeper, Vladimir Emelyanov, was launched and undergoes a test cycle, its launch into the fleet is scheduled before the end of the year. The fourth and fifth serial "Yakov Belyaev" and Peter Ilyichev "laid down in the 2017 and 2018 respectively, and are at different stages of construction.

In total, according to the state armaments program during the 2018-2027 period, the Russian Navy plans to get the 10 the latest minesweepers of the 12700 Alexandrite project.

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.

Who will explain to me the purpose of the minesweeper in modern naval warfare? Without irony, the question is in all seriousness!

[g1v2]

Detect mines and navigate ships and ships through minefields. Isn't that obvious?
Mina is a fairly simple and inexpensive way to disable enemy ships and disrupt their shipping. Again, a great way to block the approach for him.

Detect mines and navigate ships and vessels through minefields

Look at a set of 12700 electronic and mine-torpedo weapons. And you will see that its capabilities are incomparably wider.
CS “Ruberoid”, PGAS “Anapa”, GAS ZS “Structure-35”, GISZ “Altyn-M”, UDM-2, UDM-500, MTPK-2,
MRPK-1, PMR-2, OUKT-B, trawl simulator "Gelatin",
This is not a complete list.

[igorka357]

And many modern mines you name?

quick strike
The Quickstrike series of ground mines (Quickstrike - quick hit) was developed in 1983 to replace the old Destructor mines that were used in Vietnam. At the moment, this is the main American mine, adapted for aerial production from airplanes.
In fact, Quickstrike mines are conventional Mk.82-83-84 high-explosive bombs (weighing 227 kg, 459 kg and 925 kg, respectively), on which non-contact fuses and brake parachutes were mounted. Due to this, mine operations can be performed by any military aircraft without reducing the combat load.
The dumped mine uses a parachute for soft splashdown, lays on the bottom and activates the fuse. The mine fuse - the modern Mk.71 and the promising Mk.157 - is a comprehensive sensor device (located in the tail fairing), which includes acoustic, magnetic and seismic sensors, as well as microprocessors that can match and analyze signals and select specific targets. Due to this, the mine is relatively resistant to trawling, can recognize specific targets and undermine the most valuable.

The main disadvantage of this weapon was the strict requirements for height and speed of discharge. Quickstrike mines could be dropped from a height of not more than 500 meters and at a speed of not more than 600 kilometers per hour. Otherwise, the accuracy of mine setting decreased below permissible. Such restrictions seriously reduced the value of mines, especially in modern warfare at sea.
In September 2018, the U.S. Air Force showed a new generation mine - Quickstrike-ER (ER - Extended Range, increased range). The new mine is the same serial bomb with the Mark 65 fuse, but equipped with a JDAM-ER control kit. This kit is designed for the cheap conversion of unguided free-falling bombs into controlled planners, and includes a folding wing, control planes, and a GPS / INS-based control system.
Dropped from an airplane - from any height and at any speed - the Quickstrike-ER mine spreads its wings, activates the navigation system, and plans to the appointed point. Depending on the height and speed of discharge, a mine can plan up to 75 kilometers (when launched from a height of 11000 meters). The mine guidance system uses GPS satellite navigation, comparing its data with that received from the Autonomous Inertial Navigation System (INS), and can be guided to within a few meters. Having splashed down, the bomb drops its wings and behaves like a regular Quickstriker, sinks to the bottom and detonates a fuse.
The first tests of the system began in 2014. Since the system is just a combination of off the shelf, familiar and reliable components, development took a minimum of time. It didn't even require any significant software upgrade, since the JDAM-ER kit is already able to bring the bomb to the desired point. If necessary, any required stock of "Quickstrike-ER" can be quickly assembled from the existing Mk.82-83-84 bombs, Mk.71 fuses and JDAM-ER serial kits. It should also be noted that due to the widespread prevalence of JDAM kits in the world (they are used by 29 countries other than the United States), similar weapons can almost immediately go into service with other nations.
At the “Valiant Shield” exercises in 2016, a mine dropped from a B-52H aircraft successfully planned 75 kilometers and was brought down exactly to a given point. Moreover: while simultaneously dumping several (inert) mines aimed at one point, the divers who got them from the bottom found that the mines literally touched each other - their system “laid” them so precisely.
The value of this technology is hard to overestimate. In addition to significantly improving media safety, Quickstrike-ER provides the following benefits:
* The possibility of active mine productions anywhere in the world, including in the immediate vicinity of enemy bases. It seems quite real that a group of bombers by a sudden strike miners the water area near the ports and naval bases of the enemy, thereby seriously complicating the operations of its fleet.
* Ability to extremely accurate mine setting provided by GPS / INS systems. Mines “Quickstrike-ER” can be placed with an accuracy of meters, previously unattainable for air mine installations, which allows the use of mines for the exact “locking” of channels, rivers, inland waterways and entrances to the harbor.
* Ability to create minefields of any configuration. Since the mine has high autonomy from the carrier, the minefield can have any necessary configuration, without requiring the aircraft to fly over a given area for a long time. Quickstrike-ER mines can be fired in one salvo, independently taking the assigned positions - and in view of the possibility of giving the minefield any complex configuration, the enemy will experience significant difficulties with trawling.
At the same time, Quickstrike-ER mines have exactly the same dimensions and almost the same weight as the standard air bombs on which they are made. This means that one bomber can set from 24 to 36 minutes at a time. The US Air Force is currently planning to use the B-52H and B-1B strategic bombers for aerial landmines, and in the future also the new B-21 Raider stealth bombers. It is also possible to set mines from tactical aircraft, for example, deck fighter-bomber F / A-18E / F “Superhornet” and F-35B / C “Lightning II”.
American experts call the "Quickstrike-ER" mines the biggest breakthrough in air mine laying since the Second World War - and they are apparently right. Quickstrike-ER is literally revolutionizing mine warfare by giving the art of active mine-setting a whole new dimension of possibilities. Minefields can now be deployed "in real time", including for solving operational and tactical tasks directly during a military operation.
With the help of these mines, in the event of a war, for example, with China, the American fleet can completely disrupt the deployment of the PLA Navy, turning the approaches to the Chinese naval bases into an intricate labyrinth of minefields with one blow. Which will have to sweep for a long time and persistently, or risk the death of valuable units (since the mine is smart enough to recognize targets and not react to tricks). Such measures may well serve as a "trump card in the sleeve" of the US Navy, allowing to neutralize the local numerical superiority of the PLA Navy: to complicate the Chinese deployment, and buy time for the approach of American reserves.

The latest "squeak" of mine fashion.

An example offhand, so to speak: you have ships in Baltiysk, enemy planes flew by, threw a fig cloud of mines on the fairways. And you take the ships out to sea. Who will fight with mines?)))

[cniza]

And also P.L. and surface ships can instruct anything and conduct a civilian fleet, and underwater saboteurs must be fought ...

[igorka357]

Where? At the exits from our bases, if they can instruct, then our fleet will be at the bottom by that time! PDSS divers will fight saboteurs, but not minesweepers!

[igorka357]

Forgive me, of course, but if enemy planes fly over our fairways, we will no longer have a fleet, now it’s not the second world ...

[wellaut]

Some time ago, there was a large article on the VO about the deployment capabilities of our fleets. And there it was examined in detail how a potential adversary could block our communications.
How many mines can a strategist take on board? And the squadron of strategists? Yes, even if at least one of them breaks through and throws, not counting the submarines and other methods, then you can’t get hemorrhoids.
But the fact that now is not the Second World War is just sad, because in terms of the number of these very modern minesweepers we have trouble.

[Xnumx vis]

The submarine launches a mine .. It goes a certain distance, anchors in a certain place in several deep levels, tiers and waits ... for a victim ... It can be quiet for months without reacting to passing ships.

[ZAV69]

Until the war is declared, they can fly without problems, and here the mine plans to 75 km .... So it can easily be mined before the start of hostilities

[Wedmak]

Well, how they laid it, sealed it ..))
Interestingly, but the cost of such a case is very different from the steel?

[wellaut]

And what's the point of comparing in the context of the specialization of the ship? Then with a wooden case)))

[Vladimir1155]

fiberglass costs 7-10 dollars per kilogram, scrap 12 rubles, and metal 50 rubles .... that is 3 times more expensive, taking into account the need for processing of metal during installation? but the specific gravity of sekloplastik is 4 times less ...... conclusion: almost a fiberglass vessel is only a third more expensive in hull than steel (if you work in the summer) but with a displacement of 900 tons where the hull itself is about 50-100 tons, for the budget RF is very small

[Mikhail Drabkin]

It’s excellent, but how to explain .... in addition to gagging and the lack of qualified engineers and workers ... The hull of "Kurbatov" was almost completely destroyed by fire.. "!!!

How much is it possible about fires on ships at the berth or in the dock !!!
I admit that t.s. “..The smoke of war” can explain everything from disappeared funds to planning errors ...

In the words of either Comrade Stalin or Lavrenty Pavlovich, "there is a concrete name for every coming."

[Mikhail Drabkin]

What caused the cons in the commentary? I’ll take into account if that is in the content or form.

Or do you think that% of fires at the berth or in the dock is normal, part of the plan, like shrinking and spoiling in trade? Or did the names make you fear?

Do not be shy in obscurity.

[LeonidL]

I put a plus, Mikhail, because after 2014 the number of all kinds of "strange" fires has sharply increased. For example: the message "Biryusa refrigerator warehouse is on fire ... but behind the fence is the territory of the Sarmatian factory. For the uninitiated, there is the highest degree of air purification, shoe covers, dressing gowns, changeable clothes, expensive filters ... What becomes of expensive filters and the atmosphere inside the assembly workshops, if there is a huge smoking fire nearby? Second example: the other day it was reported that a certain state district power station was burning ... it was so strange that it was burning, gas exploded and caught fire 200 meters from the station ... But there is, by chance, of course, a certain LLC "Navigator", ask what it navigates and in the interests of whom. ... Any arson of a state facility is already the starting point of a serious investigation. And how many "soft" objects burned down? But the arson of a warehouse of tires, for example, paints, refrigerators and so on, in the immediate vicinity of a strategic facility, in principle, it is simple to implement, the protection there is scanty, but it is difficult to extinguish. These are losses, sometimes large, sometimes irreparable. This, in addition to the loss of material flax - tension in society. So, that fires on nuclear icebreakers, minesweepers, shipyards, sinking docks, burning refrigerators and tires, paints and varnishes ... It is possible, and this is the easiest way, to explain bungling, corruption, nature ,,, But is it necessary?

[Mikhail Drabkin]

I agree with you, maybe sabotage or sabotage.
Muddy and unacceptable; Of course it happens, but it’s true that it’s not extraordinary circumstances that cause the above, and next to the military-industrial complex.
Thanks for the addition, I will consider!
