India launched the fifth Scorpen-class submarine for the country's Navy

India launched the fifth Scorpen-class diesel-electric submarine (Kalvari). The submarine launching ceremony was held at the shipyard of the Indian company Mazagon Dock Limited (MDL) in Mumbai without the presence of officials due to the second wave of coronavirus.

The fifth of the six submarines of this series was named "Vagir". The head submarine "Kalvari", which gave the name to the entire series, entered the Indian Navy in 2017, the second submarine, "Handeri", in September 2019. The third and fourth diesel-electric submarines, Karenge and Vela, are currently undergoing sea trials. Construction of the sixth submarine, Wagshir, continues. In the process of building submarines, the schedule for their transfer the fleet has been revised several times for various reasons and currently envisages delivery of the last sub in the series by 2022 instead of 2017 as previously planned.

The submarines "Skorpen" (Kalvari) are built under a contract signed with the French company Naval Group (formerly DCNS) in 2005. The agreement, worth $ 3,6 billion, provides for the construction of six submarines of this class at an Indian shipyard with the transfer of technology to India. The new submarines are designed to replace the outdated Sindukush (Kilo) and Shishumar (Type-209/1500) class submarines in the Indian Navy.

The main purpose of the submarines of the class "Scorpion" is to fight against submarines and ships of the enemy. Submarines are built from special steel that can withstand high pressure. The entire series of these submarines is built without an air-independent power plant, but with the possibility of installing a VNEU in the process of modernization in the future.

The length of the submarines is 67,5 meters, the width is 6,2 meters, the surface displacement is 1615 tons (underwater - 1775 tons). The submarine is equipped with 360 rechargeable batteries, each of which weighs 750 kg. Maximum underwater speed is 20 knots. Crew - 44 people, including eight officers.

Diesel submarine armament - 533-mm torpedo SUT 266, anti-ship missiles SM-39 "Exocet" and mines.

Yes, they build quickly, unfortunately ...

From the text: "The entire series of these submarines is being built without an air-independent power plant, but taking into account the possibility of installing VNEU in the process of modernization in the future. " It is unclear what kind of VNEU the Indians are going to install on these submarines. There are many types of them, including Stirling engines, electrochemical generators, steam generators ...

So the Indians have always been cunningly done, will beg for any vneu to the last, but always with the transfer of production technology.

Hindus have collected so much of everything around the world ... that they can successfully fight - with themselves! Ours is a stranger, in this country, the concept is abstract. I didn’t track it in the Fleet, I can tell from the arrow ... full! Here words from the White Sun of the Desert are more suitable than ever - he has grenades of the wrong system. A variety of models and calibers, it's certainly fun, only army and naval logistics is complete opa. The chief quartermaster seems to be how their multi-armed god should be - this is there, and this is here

I have not heard that this class of French boats "Scorpen" with VNEU. It's not like hanging a bow. At least the French sold the Chileans and Brazilians without VNEU, and even this boat will be of a different class. It's one thing, you pop up every 4 days, and another thing every 40. I have a suspicion that the "cunning" Hindus' paddling pools have outraged them. After all, this class of boats is made only for export, so they are pumped in in all possible ways.

I would not say fast. The dates have been shifted until 2022. Launching, not yet commissioning. Not to mention the "vinaigrette" with weapons for submarines - missiles, torpedoes, Russian, German, French mines. Retraining l / s, etc.

[Lech from Android.]

Not bad, the Indians bought the French along with the technology ... Presumably this submarine will oppose the Chinese Navy.

[Pavel57]

And how often does she need to charge the batteries?

[qaz]

44 people crew. You can go crazy.

[Yura]

And as you would like, the crew itself and plus the mongrels of each officer, so this is at a minimum.

[Jacket in stock]

Why didn't they buy all the submarines?
The Indians could buy without the transfer of technology to VNEU, it would still be better than nothing.

What seems to me with the number of batteries there is too much ...

Yes, everything is fine, considering that this is a disguise of rowers. Something I was naughty today.

[tech3030]

"The submarine is equipped with 360 batteries, each weighing 750 kg." Multiply the weight by the number - How much does the submarine weigh?

I was joking, I was just joking, there are no grounds for polemics, especially since in this matter I am, to put it mildly, a layman.

[tech3030]

Yes, I myself am! I just figured the batteries weigh 270 tons. I'm just curious!

[Pashhenko Nikolay]

The weight of the boat is its surface displacement. Why calculate the batteries.

[tech3030]

They weigh a lot, for sure they take up a lot of space in the case. About this I wanted to say. But not so expressed my thought.

[Thrifty]

"The hull of the boat is made of special steel that can withstand pressure" - and we probably do the hulls of our submarines from foam? ??
