В ОСК сообщили о закладке двух больших подлодок проекта "Лада" в этом году
Решение о заключении госконтракта на строительство новой серии судов принимает Минобороны России
МОСКВА, 22 марта. /ТАСС/. Две большие многоцелевые дизель-электрические подводные лодки проекта 677 серии "Лада" будут заложены на судостроительном предприятии "Адмиралтейские верфи" (входит в Объединенную судостроительную корпорацию, ОСК) в текущем году. Об этом ТАСС сообщили в ОСК.
"Закладка двух больших подводных лодок проекта "Лада" состоится в нынешнем году", - сказали в холдинге.
В ОСК отметили, что решение о заключении государственного контракта на строительство новой серии лодок этого проекта принимает Минобороны России.
Головная лодка серии "Лада" Б-585 "Санкт-Петербург" в сентябре 2021 года вошла в боевой состав Северного флота. Подлодка Б-586 "Кронштадт" и третья по счету субмарина серии Б-587 "Великие Луки" готовятся к передаче флоту в 2022 году.

Подводные лодки проекта 677 относятся к четвертому поколению ДЭПЛ и на сегодняшний день признаны самыми современными и перспективными отечественными неатомными подводными кораблями как с точки зрения боевой эффективности, так и по другим тактико-техническим характеристикам. "Адмиралтейские верфи" являются единственным заводом - строителем подлодок данного класса.

USC announced the laying of two large submarines of the Lada project this year
The decision to conclude a state contract for the construction of a new series of vessels is made by the Russian Defense Ministry
MOSCOW, March 22. /tass/. Two large multipurpose diesel-electric submarines of Project 677 of the Lada series will be laid down at the Admiralty Shipyards shipbuilding enterprise (part of the United Shipbuilding Corporation, USC) this year. This was reported to TASS in USC.
"The laying of two large submarines of the Lada project will take place this year," the holding said.
The USC noted that the decision to conclude a state contract for the construction of a new series of boats of this project is made by the Russian Defense Ministry.
The lead boat of the Lada B-585 Saint Petersburg series joined the Northern Fleet in September 2021. The B-586 Kronstadt submarine and the third B-587 Velikiye Luki series submarine are being prepared for transfer to the fleet in 2022.

The submarines of Project 677 belong to the fourth generation of the DPL and are currently recognized as the most modern and promising domestic non-nuclear submarines both in terms of combat effectiveness and other tactical and technical characteristics. Admiralty Shipyards is the only factory - builder of submarines of this class.
Two submarines were being laid down in 2022, and the lead boat was part of the Northern Fleet and joined in September 2021. They laid down three to start with and the first was completed but the second two were put on hold when the performance of the first was not what they expected, so after work on the first ironed out all the bugs and problems and changes were made those changes were applied to the two other boats on the slips so they were completed using the improvements applied to the first boat. Those two other boats were to join the navy in 2022.
So there are five subs in total so far, two have only recently been laid down and the first entered service in September 2021 and the two others will be put into service soon if not already.
No mention of the first B-585 being withdrawn from service.

Two Lada submarines were laid down in St. Petersburg on Russia Day
The Commander-in-Chief of the Russian Navy Nikolai Evmenov took part in the laying ceremony
ST. PETERSBURG, June 12. /tass/. Two diesel-electric submarines of the Lada project 677 were laid on the Day of Russia at the Admiralty Shipyards in St. Petersburg. This was reported on Sunday in the press service of the company.
"The Vologda and Yaroslavl submarines have become the fourth and fifth ships in the Project 677 series under construction at Admiralty Shipyards JSC for the Russian Navy," the report says.
It is noted that the Commander-in-Chief of the Russian Navy Nikolai Evmenov took part in the laying ceremony. By his order, the submarines were laid down simultaneously with four more ships at other shipbuilding enterprises of the country. The construction of the mine defense ship project 12700 "Polar" was launched at the Sredne-Nevsky Plant in St. Petersburg, the corvette project 20385 "Reasonable" was laid at the Amur Shipyard, and the research ships of project 03182p "Leonid Bekrenev" and "Boris Bobkov" were laid at the Zelenodolsk plant named after A.M. Gorky.
According to Evmenov, the Russian navy has "a powerful scientific and design potential, centuries-old experience in the construction and operation of ships by highly qualified personnel." According to the admiral, by the end of 2022, the Navy will receive 46 warships and support vessels.
The press service of JSC Admiralty Shipyards noted that the construction of a series of submarines 677 of the Lada project is being carried out according to an adjusted project, based on the results of the pilot operation of the lead ship St. Petersburg, which serves in the Baltic Fleet. The ships have upgraded the control system of the ship's technical means, the electric propulsion system, and the navigation complex. By the end of 2022, the second ship of the Kronstadt series, which was launched in 2018, will be transferred to the Northern Fleet. In 2015, the company laid down the third ship of the series - Velikiye Luki. On June 12, after the docking of the solid hull, completion work continues on it. The company started cutting metal for Vologda and Yaroslavl, the fourth and fifth boats of the project, in February of this year.
The submarines of Project 677 belong to the fourth generation of non-nuclear submarines and are recognized as the most modern and promising domestic ships of this class, both in terms of combat effectiveness and other tactical and technical characteristics. Currently, the corresponding ships are being built only at the Admiralty Shipyards in St. Petersburg.
This article says the first boat is operating in the Baltic Fleet, which I would think it would be ideal for.
It seems to say one of the two boats is going into service at the end of 2022, while the other is still being completed and has not yet been launched...

I know Russians have developed energy packs using hot radioactive elements.
Thermoelectric power plants have been used in satellites, but I think they would like to develop something that uses hydrogen... especially in the form of hydrocarbons as that would be a useful technology.
People wont be allowed access to nuclear batteries any time soon even if they were amazing and safe, but something that used petrol or diesel or kerosene and created a solid block of carbon that you could then sell or recycle to make carbon nanotubes or carbonfibre... ie a relatively expensive commodity... then that is a rather more useful goal and investment of money.
Replacing internal combustion engines with fuel cells that used hydrocarbons but did not create carbon based gas emissions is the real goal because the creation and distribution of fuel already exists and is extensive, an being able to use that to distribute hydrogen without enormous pressure containers or super cold gas storage would be really handy.
Essentially all the advantages of fossil fuels but without the pollution that is bad for the climate.
