The Ministry of Defense has decided on the timing of the start of state tests of diesel-electric submarines "Kronstadt" of project 677 "Lada"

Submarine "Kronstadt" project 677 "Lada" will enter the combat structure of the Russian fleet next year, this follows from the timing of the state tests of the submarine. This was reported by the press service of the Ministry of Defense.

Diesel-electric submarine "Kronstadt" will begin state tests at the end of December this year. Such terms were approved by the Commander-in-Chief of the Navy Nikolai Evmenov. Currently, the submarine is completing, or has already completed, factory sea trials, which lasted quite a long time. Now the submarine should be at the Admiralty Shipyards and is preparing for state tests. There is no exact information about this.

At the end of December this year, JSC "Admiralty Shipyards" will begin state tests of the submarine project 677 - "Kronstadt"

- said in a statement.

The diesel-electric submarine "Kronstadt" is the first serial submarine of project 677 "Lada" after the lead "St. Petersburg". The construction of the submarine turned into a long-term construction, carried out with long interruptions, stops and adjustments to the project. The laying of the submarine took place in July 2005, in 2009, by decision of the Ministry of Defense of the Russian Federation, the construction of the order was suspended until 2013, the launching took place only in 2018. At the end of 2021, the submarine entered sea trials for the first time. According to the shipbuilding enterprise, "Kronstadt" was completed according to the adjusted project, taking into account the trial operation of the lead submarine of the series.

According to the latest information, the Kronstadt will replenish the combat strength of the Pacific Fleet, although it was previously reported that the submarine will go to the Northern Fleet, where it will join the lead submarine of the series. However, all this is still at the level of rumors, so we will wait for the official announcement.

VNEU is not and is unlikely to be in the foreseeable future. Therefore, we rivet what we can, and not what the military needs. But soon, indeed, our diesel-electric submarines will be unparalleled in the world, because in the rest of the world it will not occur to anyone to build (or purchase) non-nuclear submarines without VNEU.

[Osmodey]

Good afternoon. And on a global scale, besides the French, does anyone use VNEU?

[UAZ 452]

Uh... And the Swedes? Germans? Japanese? Now also the Turks. Like they write about Spain. Well, those to whom they sell them.

[Osmodey]

I read about the Swedes and Germans. I'll take a look at the rest, thanks!

[Smirnov Sergey]

The Japanese use And it seems like they sold their boats to the Australians. Like the Swedes too.

[Ezekiel 25-17]

Nuclear submarines are being built by the Russian Federation, the USA, France, Great Britain, this is standard. The presence of VNEU on it is not necessary; Suitable for diesel and battery.

[UAZ 452]

Uh ... And what is the connection - nuclear submarines and VNEU (I didn’t really understand about diesel on nuclear submarines either)? If tomorrow they learn how to make compact, relatively cheap and low-noise (at the level of modern VNEU) nuclear reactors, then all of today's developments in anaerobic propulsion systems will be safely put on the shelf, but so far, alas, they have not learned.

[shikin]

I think VNEU with a Stirling engine, with fuel cells is a dead end. In this case, the diesel and batteries from the boat do not disappear, but a bulky additional remote control plus liquid oxygen and liquid hydrogen is added. But the progress in the development of batteries is much more interesting. In this case, it will generally be possible to create a hybrid propulsion system with full electric propulsion with a long submerged course. By the way, Lada has full electric propulsion.
And one more thing: can anyone justify why a small boat designed to protect coastal waters needs to spend more than 10-15 days underwater?

And one more thing: can anyone justify why a small boat designed to protect coastal waters needs to spend more than 10-15 days underwater?

First you need to justify - why submarines to protect coastal waters? On the Black Sea, coastal-based anti-ship missiles did an excellent job with the flagship of the Black Sea Fleet, while the Ukrainian Navy did not have a single submarine. And the fleet, in fact, was not. To protect coastal waters, there are coastal anti-ship missiles, coastal-based aviation, minefields, and, in the short term, autonomous underwater vehicles.
A submarine with a crew (not a strategic one) is presented as a weapon for attacking the coast, the enemy’s sea transport communications, but this requires stealth, first of all, noiselessness and long-term autonomy. There is currently nothing in the Russian Navy that meets these two requirements at once (they prefer to compare the noiselessness of our "black holes" with our own boats of previous generations, but by no means with their modern foreign potential opponents).

[Ezekiel 25-17]

Boats with VNEO are in service with fleets that do not have nuclear submarines.

[Buyan]

Very well. I wish you to go through all the stages and excellent service!

Diesel-electric submarine "Kronstadt" will begin state tests at the end of December this year. Such terms were approved by the Commander-in-Chief of the Navy Nikolai Evmenov.

The award of the quarter is covered!

Vladimir Vysotsky, the former commander-in-chief of the Navy, said in 2012: “The declared technical characteristics of the Project 677 submarines are not confirmed on tests of the lead submarine Saint Petersburg. Russia does not need it. "

Earlier, the Russian Navy planned to build 20 boats of Project 677, but the lack of an air-independent installation and a number of other problems led to the fleet abandoning Project 677. Only two already laid down boats will be completed - Kronstadt and Velikiye Luki. Moreover, these two boats will also be built without an air-independent installation (VNEU), as reported by the general director of the Admiralty Shipyards, Alexander Buzakov.

[Codett]

Unfortunately, the fleet has to take what they give, it does not have VNEU and this is very bad, although they wrote about other problems with the boat, but this is the main one. Hydrogen fuel cells, similar in principle to the promising Lad engine, which will not eventually appear on it, are used on German submarines of projects 212 and 214. These submarines have already become a popular export product and are produced for the fleets of Italy, Norway, Turkey, Greece and South Korea. A similar mechanism will be used on Spanish diesel-electric submarines of the S-80 type.
On Swedish boats of the Gotland type, a Stirling engine was used as a VNEU. The same system is used by Japanese developers on the Soryu project. Last year, Japan was the first in the world to launch a promising diesel-electric submarine with lithium-ion batteries
