Morning, bro...
And 2 more launched + 2 more under construction..

How do you do Very Happy

There is 4 in construction phases and named, and if I am not mistaken even more are ordered - some info flashed in front of my eyes that 16 pcs are firmed at the moment. I will try to remind myself where I saw that.

...got q dumb question, but what are the full range of the capabilities of these mine sweepers? I tried reading up about them but they clearly seem very important to the Russian navy. What kind of capabilities do they have that make them so important?

Trawling

But jokes aside, the Soviet navy always put a lot of attention to mine warfare. Having dozens of trawlers was part of that strategy. Seems that not much changed, it is a part of the area denial strategy I guess.
New trawlers can be used for reconnaissance, bottom mapping, diversion or antidiversion duties, guarding under sea infrastructure etc.

In Primorye, the minesweeper "Anatoly Shlemov" tested the latest equipment
After the completion of the verification activities, the ship will be commissioned into the Pacific Fleet

VLADIVOSTOK, 30 November. /TASS/. The minesweeper "Anatoly Shlemov" project 12700 "Alexandrit", built for the Pacific Fleet, during factory sea trials in Peter the Great Bay, tested the marine television complex and navigational radar station, the press service of the fleet said on Wednesday.

"During the next stage of the factory sea trials, a marine television complex was tested on the ship in test mode, which meets all modern requirements in solving the assigned tasks. Also, at the exit to the sea, industrial specialists and the crew of the newest sea minesweeper tested a navigation radar station," the report says. .

After the completion of the verification activities, the sea minesweeper will be commissioned into the fleet with the hoisting of the St. Andrew's flag on it.

The sea minesweeper "Anatoly Shlemov" is the third for the Pacific Fleet and the seventh in the project 12700 series, built at the Sredne-Nevsky Shipyard. Two similar minesweepers are serving in Kamchatka - "Yakov Balyaev" and "Pyotr Ilyichev".
The ship has a unique, largest monolithic fiberglass hull in the world. The service life of such a body is longer, and the weight is much less.

The minesweeper "Anatoly Shlemov" will be the 7th project 12700 minesweeper delivered to the Russian Navy.

...got q dumb question, but what are the full range of the capabilities of these mine sweepers? I tried reading up about them but they clearly seem very important to the Russian navy. What kind of capabilities do they have that make them so important?

In very simple terms a sea mine is like a land mine... cheap and easy to produce and if you are at a disadvantage to your enemy you can kill their mobility and speed by dropping them all over the place... of course you also limit your own mobility at the same time if you are not properly equipped to deal with mines too.

But then even if neither side uses mines (incredibly rare though), there will be unexploded ordinance to deal with everywhere anyway.

In combat using mines in specific places allows you to limit the directions the enemy can approach your positions... you can channel them into areas you want them to go and punish them for going any other way.

Obviously sea mines are more of a problem because they can move with currents and tides and all mines have the problem that they don't care about friend or foe and they don't stop fighting just because the two or more sides fighting sign some piece of paper.

Needless to say dedicated anti mine ships are not common in most navies, while the locations they will need to be looking for mines will be enormous... when a real war starts you need lots of dedicated vessels to be continuously looking for mines and clearing them, that is around friendly bases and in friendly waters and international waters you want your ships to sail through.

It is critical you have lots of anti mine ships on hand to deal with mines and also enemy divers and perhaps even sea surface drones moving forward... the Russians take this all very very seriously and have large numbers of mine clearing vessels... they have an enormous range of sea mines of various types that can be delivered by ships, by subs, and by aircraft.

They even have a special pressure magnetic fuse that can be fitted to aircraft bombs and carried by bombers and dropped into shallow water near enemy positions and ports... they sink to the sea floor and then wait for a ship to sail past with a suitable magnetic pattern... and boom.

A bomber or transport plane flying low and slow over any waterway could be laying mines, which might be FAB-1,500 or FAB-3000 bombs sitting in 100m of water waiting to blow up under an unsuspecting ship or sub sailing through that area...

Russia has a lot of mine sweepers and so do the Chinese, but the rest of the world not so many...

Source: the new minesweeper "Anatoly Shlemov" can be handed over to the Russian Navy in December
According to a source in the military-industrial complex, the ship is currently being tested in the Pacific Fleet.

MOSCOW, 1 December. /TASS/. The minesweeper "Anatoly Shlemov" of project 12700 (code "Alexandrite") can be transferred to the Navy (Navy) of the Russian Federation after testing until the beginning of 2023. This was reported to TASS by a source in the military-industrial complex.

"Currently, Anatoly Shlemov is being tested in the Pacific Fleet (Pacific Fleet). If they are successfully completed, it can be transferred to the Pacific Fleet at the end of December," he said.
TASS does not have official confirmation of this information.

In turn, the head of the Sredne-Nevsky Shipbuilding Plant, Vladimir Seredokho, told TASS that before the end of the year, it was planned to transfer two minesweepers to the Navy, two more in 2023, one in 2024, and two annually from 2025.

About minesweeper

"Anatoly Shlemov" is the third sea minesweeper of project 12700, intended for the Pacific Fleet, and the seventh "Alexandrite" in a row. A minesweeper of this type "Yakov Balyaev" is serving in Kamchatka, and the second such ship, "Pyotr Ilyichev", was handed over to the fleet in mid-November.
The minesweeper Anatoly Shlemov was laid down in July 2019 and launched in November 2021. Sea trials started in Primorye in early November 2022.

Project 12700 "Alexandrite" was developed by the Almaz Central Marine Design Bureau. Ships of this type are designed primarily to search for and destroy mines in the waters of naval bases. They are equipped with hydroacoustic stations located both on board and on remote-controlled and autonomous underwater vehicles. At the same time, "Alexandrites" can also use traditional minesweeping weapons.

The advantage of the composite minesweepers of project 12700 is considered to be higher strength in comparison with steel hulls, which ensures greater survivability when searching for mines. The service life of a ship made of monolithic fiberglass is longer than that of a hull made of low-magnetic steel, and the weight of the hull is much less. The displacement of the ship is 890 tons, length - 61 m, width - 10 m, speed - 16.5 knots, crew - 44 people. The ship has high maneuverability due to the use of an effective set of various thrusters.
