Nuclear submarine "Leopard" archive

The Northern Fleet will soon receive the project 971 (Schuka-B) nuclear submarine Leopard, which has undergone repair and modernization. According to TASS, citing a source in the shipbuilding industry, the submarine will be launched at the Zvezdochka Ship Repair Center (CS) on December 25.

According to the interlocutor of the news agency, the nuclear submarine Leopard, which has undergone repair and modernization, will be taken out of the boathouse "under the herringbone."

The nuclear submarine "Leopard" after the completion of the repair and modernization will be withdrawn from the boathouse "under the herringbone" - December 25 this year

- leads TASS source words.

Multipurpose Submarine of the North fleet K-328 Leopard arrived at Zvezdochka at the end of June 2011. In May 2012, the ship was placed in a boathouse and equipment dismantling began on it. In 2014, it was reported about plans to complete work on the submarine in 2015, but the work initially went behind schedule due to a delay in documentation from the designer of the SPMBM "Malachite".

Details of the modernization were not reported, it is known that a number of onboard systems were changed on the nuclear submarine. In addition, the Leopard became the carrier of the Kalibr cruise missiles instead of the RK-55 Granat. The submarine's torpedo tubes have been redesigned for launching a new cruise missile.

The nuclear submarine was laid down on October 26, 1988 at the Sevmash shipyard in Severodvinsk, received the name "Leopard" on January 24, 1991, launched on June 28, 1992, and entered the fleet on February 5, 1993.

It is part of the 24th "Animal Division" of the Northern Fleet of the Navy. In addition to the Leopard, the division also includes the Tiger, Vepr, Panther, Wolf, and Cheetah submarines.

Well, fine.

[Borik]

QUESTION?? And after launching, some more work will be carried out on it or after the holidays it will be factory tested ???

[senima56]

At least mooring and then sea trials after dock should take place. So, most likely, no earlier than the first quarter of 2021, it will return to the Federation Council.

[Machito]

And the rest of the boats of this project will be modernized and in what time frame?

[seregin-s1]

Five (with the "Leopard") in the ranks, five on modernization. This year the Vepr was handed over to the fleet. The rest are tryndets!

After the holidays, the channel will be equipped and will open at the beginning of June, i.e. as usual.

9 years! Much nicer.

Are you aware of the scope of work performed during the modernization?

And what will the project 971 Schuka-B multipurpose nuclear submarines gain as a result of repairs and deep modernization, and who will be the first to be issued? "- this question was asked by Rossiyskaya Gazeta to Nikolai Kalistratov, General Director of Zvezdochka CS.

- The ships of this project, - our interlocutor recalled, - were built at Sevmash and the Amur plant in the 80-90s of the last century. Their designer - SPMBM "Malachite" - initially provided for them a complex of medium repairs after ten years of operation. But neither ten years, nor twenty years later, none of the ships of the 971 project underwent average repairs. Now, taking into account the current situation and new tasks, the nuclear-powered ships of the 971 project are being upgraded with large-scale changes to the ship according to a separate project ...

For obvious reasons, the director of Zvezdochka did not go into details, but made it clear the following:

- The technical potential laid down in the modernization of the ships of the Shchuka-B project will be comparable to the fourth generation Yasen multipurpose nuclear submarines of the same Malakhit design bureau. In terms of the volume of work, this is comparable to the construction, and in terms of money, it is half the cost of a new ship.

The preparation of production at the enterprise began in advance. The first step was to master the technology of aggregate replacement of large assembly and assembly units, restoration of structures and depreciation of zonal blocks without unloading them in cramped conditions. In parallel, the introduction of other advanced technologies and samples of ship technology was under way.

The creation of a virtually new ship required, according to Nikolai Kalistratov, the mobilization of the entire technical potential of the enterprise. Hundreds of new technologies and technical solutions were developed and agreed with the designers and basic research institutes.

“The upgraded Project 971 ships,” the Zvezdochka head is convinced, “will take a worthy place among the fourth generation multipurpose nuclear submarines and will be in demand for solving a wide range of tasks for the Russian Navy and the Ministry of Defense as a whole.

Isn't it easier to build a new one? And yes, the volume is large and the money is probably, as three new ones mastered.

[Orange bigg]

Didn't read the quote carefully. Here is an excerpt from the quote.

In terms of the volume of work, this is comparable to the construction, and in terms of money, it is half the cost of a new ship.

[lis-ik]

But sooo long.

[Orange bigg]

On the other hand, they retained the combat unit, and now there is a shortage of attack nuclear submarines.

[Alex777]

So all the cooperation, thanks to which it was built, was destroyed.
Here the question is rather not what they did for a long time, but what they did.

So yes, the case when the result is achieved not thanks to, but in spite of. Especially when you consider the problems of varying degrees of severity that arose throughout the entire cycle of work on this project.
But, damn it, I was afraid of the master's work.

[g1v2]

Only Sevmash builds an apl. He has everything crammed for years to come. At the beginning of the year, he simultaneously built and tested 13 APLs. Now Prince Vladimir has been surrendered, Kazan must also be surrendered. But immediately they laid down 2 Ash trees. Next year, in theory, one strategist and one Ash tree should be handed over, but there Boreyev already needs to be laid to replace the oldest dolphins - plans have been hammered for years to come. Pt Pike-b, although partially, will have to be modernized.

[frog]

A little ... if they are building for ten years ...

There were about 30 subcontractors in the cooperation. Half from the near abroad, which quickly merged. Therefore, we had to push ourselves up in an adult way. As a result, it turned out what a colleague OrangeBigg (Alexander) wrote. Special thanks to him for the info.

[Thrifty]

The bear is missing this flatility! And, another hedgehog

[fruc]

Such names are not relevant. The new submarine could be called "Chupacabra"

[swnvaleria]

bears, hedgehogs, chupacabras, something is not right for the animal flotilla, but if a new boat is named after a predatory animal with a very beautiful fur, a scribe who will immediately make sense, and no one will look for a meeting with him!

Mooring tests, factory sea trials, state tests, at the very end, interior painting and finishing. Signing of the deed, delivery to the fleet. By the summer it is possible ... after working out the course tasks, he will be included in the permanent readiness forces.

S 2011 to 2020 v remonte.
Uzhas.

Das ist fantastisch. very good.

Esli eto ne litovskaya familia, a vyrazhenie emociy, to naprasno. Nichego takogo uzhasnogo, a naoborot - uspeshnoe zavershenie rabot. I da, zdes' glavnoe - sam fakt modernizacii s vozvrascheniem v stroy fakticheski novoi MCAPL. Posle reinkarnacii iz "rodnogo" v nei razve chto korpus, i tot ne ves'.

[Nross]

Hmm ... Camping with personnel at Sevmash is not very dense.
Sevmash needs to be duplicated somewhere. If not the construction of new ones, then at least the RSM nuclear submarines should be mastered somewhere.
Theoretically, it can become a "Star", but there is an order for civilian life.
In Koms, for example, you can try to expand.
