The fourth ship built for the Varshavyanka Pacific Fleet made its first deep-sea dive as part of sea trials

Diesel-electric submarine "Mozhaysk", built for the Pacific fleet, continues to undergo factory sea trials in the waters of the Baltic Fleet. During the next exit for testing, the submarine made the first deep-sea dive.

The fourth "Varshavyanka" for the Pacific Fleet, as part of the tests, plunged to a depth of 190 meters at one of the sea ranges of the Baltic Fleet. The crew and commissioning team of the Admiralty Shipyards are on board the submarine. During the dive, they checked the operation of the systems and mechanisms of the submarine, and also worked out the control of the submarine at depth. Four days ago, on August 31, Mozhaisk made its first dive to a depth of 50 meters.

After the completion of the underwater part, the crew of the Mozhaysk submarine surfaced and continued to carry out testing activities in accordance with the plan

- declared in the Ministry of Defense.

As with the first dive, the safety of the submarine was provided by the SS-750 rescue ship, as well as warships and aviation Baltic Fleet.

"Mozhaysk" will enter the fleet in November this year. After the official ceremony, the submarine will remain in the Baltic to practice combat training tasks, the inter-fleet transition to the Pacific Fleet is scheduled for next year.

"Mozhaysk" is the fourth serial submarine built in the interests of the Pacific Fleet, after the lead "Petropavlovsk-Kamchatsky" and serial "Volkhov", "Magadan" and "Ufa". The submarine was laid down on August 23, 2021 and launched on April 27, 2023. To date, the company is completing the construction of the last submarine of the Yakutsk series, also laid down in August 2021, it is planned to transfer it to the fleet next year, at which the series will be completed.

Is 190m a deep sea dive? Yes, she has a working depth of 200m, and the maximum depth is 300m. Here "KOMSOMOLETS" went 1000m (1km), wow!

Tests. Boats and crew. Suddenly, a low-quality rivet will be knocked out by outboard pressure or the torpedo operator will open the wrong valve due to lack of coordination.
And "Komsomolets" is a lost technology. Both materialized and social.

[Saburov_Alexander53]

Mikhail, the torpedo pilots on this task sit quietly, like mice and do not touch any valves in the compartment. You confuse them with bilge drivers, but they will not touch anything if the dive is going according to plan and everything is controlled from the CPU. And for some reason I don’t remember the rivets on modern boats, usually seals on the outboard holes, of which there are dozens in each compartment, are usually poisoned. Here they must be strictly monitored and reported to the CPU in time if it starts to poison. In this case, the dive is suspended and the stuffing box is tightened with an ordinary wrench.

[Saburov_Alexander53]

No one said that these were tests for the maximum depth of immersion. Such a test is done once after launching or after overhaul. On my submarine 629A pr, the maximum depth was 300 m according to the factory passport, but no one in the Division ever dived below 270 m, and even then, no more than once a year when passing the corresponding naval task. The hull of boats from such compression greatly "ages", acquires microcracks. Therefore, no one unnecessarily torments iron.

[dump22]

Even a depth of 190m in the Baltic is very difficult to find.
The greatest depth of the Baltic Sea is 470m (Landsort Basin), and the average depth is only 51m.

And in our part of the Gulf of Finland there are no places deeper than 120m at all.

And, you know what Komsomolets is and how you had the conscience to compare Varshavyanka with the heroically deceased, Komsomolets nuclear submarine. I have a friend who survived this terrible disaster. (((
On that day, the entire Federation Council was built and reported on the death of Komsomolets, this was not the case under the USSR.

[Saburov_Alexander53]

died heroically, APL Komsomolets.
I can not turn my tongue, call the death of "Komsomolets" heroic. Gross mistakes were made to control the high oxygen content in the 7th compartment, and when it flared up, all the actions of the CPU (Commander) only led to a deterioration in the position of the ship, when they supplied the VVD to the aft ballast tanks to eliminate the list, but they did not understand that the gaskets had already burned out on the VVD pipelines and only fanned the fire in the compartment. As Romanov, Deputy Chief Designer of the boat, put it, the ship would have survived if the crew had simply done nothing. The fire in the compartment would go out on its own, and the ship would have enough buoyancy for any towing to the base.
So they drowned not only the unique nuclear submarine, but also ruined half of the crew, not being able to drop automatic life rafts into the water and use the rescue pop-up camera.
It is difficult to recall a greater disgrace in the Navy, except for the rescue operation on the Kursk nuclear submarine, but it was not the fault of the crew.

[vadivm59]

what does your comrade and the death of the nuclear submarine have to do with it, and also my conscience? This submarine did not even reach the working depth, but the author presents it as a great achievement. that's what I'm talking about.

[Dmitry Zadorozhniy]

Well, so, the Omerigan "sea wolves", they walk about 160 meters. And! "Backward Russia" is building normal two-hull boats. Avotvamerigevse all! Sea Woolfs, Virginia, one and a half hull.

[Saburov_Alexander53]

Moreover! "Backward Russia" is building normal two-hull boats.
Dmitry, you are behind the times, we also began to build "one and a half hull" ones. But it seems to me that you, in principle, do not understand what are the advantages or disadvantages of the two options for submarines. Maybe it's time to start making triplets? Let's rub our noses to the Omerigans!

[Aag]

... And do the submarines want "seven feet under the keel", or only the NK, to the ships?

"seven feet under the keel"

This is hard trolling for divers.
"So that the ascent is never the last."

"So that the ascent is never the last."

So that the number of ascents is equal to the number of DIVES!
No other way...

[Saburov_Alexander53]

We preferred "Seven Feet Under the Kilt". The Scots immediately understood what it was about ...

[Fast_mutant]

Today it’s 190m deep! We haven't dived in so long! Well, "200 working, 300 ultimate" back in World War II was quite achievable. And on the other hand, where should she dive deeper? In the Baltic?

Fourth "Varshavyanka" for Pacific Fleet

Well, “200 working, 300 maximum” was quite achievable back in World War II.

The Soviet submarines of the "C" and "K" series had the maximum maximum diving depths - 100 meters. If we take the performance characteristics of p/l from 43-45.

[bone1]

And where did she dive deep-in the Baltic then?

[Anton_from_Brest]

Any news about what will be built after Yakutsk?

[Sergey39]

There is talk of boats for the Baltic and Northern Fleets. "War plans will show."

[Boa kaa]

Quote: Anton_from_Brest

Any news about what will be built after Yakutsk?

I was also scratched by the phrase:

To date, the company is completing the construction of the last submarine of the Yakutsk series, also laid down in August 2021, it is planned to transfer it to the fleet next year, this will end the series.

And then what? 677A project or something else NAPL-ovsky thread? And when will it be? Not "Admiralty Shipyards", but some kind of "Baltic fog", the right word!

[Tests]

vadivm59 (Vadim), dear, did you try to compare a pony and a Vladimir heavy truck in terms of carrying capacity? And what about the career BelAZ and Lada Vesta?
Diesel-electric submarines you famously compared the serial and experimental nuclear submarines in depth ...

[vadivm59]

what does horses and all sorts of cars have to do with it? The author gave an ordinary dive (even less than the working depth) as a record and a sensation. So I gave an example of a dive record, that's all. even the first) and a record one, you catch the difference.

Explain what was not in the USSR? Komsomolets died just under the USSR ...

[orionvitt]

to a depth of 190 meters

And I thought that such depths still needed to be found in the Baltic. It turns out there is.
