mind it! http://thegungeek.com/SGP/download/file.php?id=4919

Sachin, the construction of 3rd boat was widely reported and is noted in wiki as well. it should begin harbour trials soon, as Arighat enters the pre-induction phase to get into IN next year.

in comparison to us using the very latest concept of large tube with UVLS sub caliber adapters, the PLAN SSBNs look weak, old design, lachaar and majboor. I heard their prolific Song class SSK was also a resounding flop. probably the Yuan which is sinicized Kilo is a flop too, hence the keeness to sell to TSP.

Hindu article from 2017. just change the name to Arighat.

https://www.thehindu.com/news/national/ ... 862549.ece

Aridhaman, of the Arihant class, will carry several new pieces of equipment including new-generation sensors and periscope, compared to the first ship.

Construction of the third submarine of the same class is under way in four different parts, and could be completed approximately in a year. This would also be of the same size as Arihant and Aridhaman, but possess more advanced weapons and sensors. The third submarine is planned for launch in late 2018.

As soon as Aridhaman is launched, the final integration of the third submarine will begin in Visakhapatnam, it is learnt.


^^^ this means the 3rd sub launch into water and reactor start may be imminent. 1H this year for sure.

On google earth image 1 can see

-1 nuke sub under construction, there are some more covered docks where we dont know what being constructed.

- 2 Nuke subs, 1 INS Chakra and 1 INS Arihant class side by side each other

- 2 Kilos in harbour plus 1 Kilo in dry dock

what don't know , are there any subs out at sea?

If you see SBC on Google earth and compared with the dry docks next to it, SBC should have only one dock so can accommodate only one SSBN. The next sub would be constructed as modules and should be getting finished in the dry dock. So the second sub has to get out of the dock for the work on third to start. Since the second has been out for more than a couple of months like hnair has pointed out, I came to the conclution that work on third will be in full swing now.

I dont think any construction on a nuclear sub will be happening outside the SBC. The subs is on the operational side of the harbor, so i presume that it is undergoing trials or should be undergoing trials very soon

If the third boat is on harbour trials, then it shows when there is clear will, things get done. With proper funding and clear line of authority, in this case PMO, gets most of the difficult things done.

When there is a need of tech of national importance, we should get it done through PMO. Not MOD. Like nuke sub, jet engine is a good candidate.

Think 3 baby boomers are good enough. We need to start building Vanguard class sized subs. And simultaneously build SSNs.

i wonder why the jin submarine has a huge number of holes on sides of its missile section while vanguard has a kind of "panel" in that region and exposes almost no holes..the troimphant class does not even show any "panel" its butter smooth

see and compare

per a sanjay badri maharaj article the S5 and S6 will be 13,500t and cart 12 x K5 (official range 5000km) or 12 x K6 w/MIRV (official range 6000km)

http://gentleseas.blogspot.com/2019/01/ ... ution.html

the plan for a new line of 6 SSN is also defined but actual work cannot begin in parallel until SBC is expanded maybe...it will take some time for S5 and S6 to be done.

troimphant/vanguard/colombia/borei are in 16 SLBM load. the 24 load of the Ohio is being downsized in Colombia which tries to use all it can from virginia class to reduce bespoke design costs.

Why don't we give order to L&T Kattupalli. It was built to build submarines. Or is the govt little apprehensive on giving SSN orders to pvt shipyards?

The 6 SSNs must be taken up in parallel to be of use to yhe IN, for both attack ops as well as protecting our SSBNs and CBGs.One metjod is to build the modules by L&T which is doing so already for the SSBNs and assemble them at Vizag, the new SSBN base being built
or at L&T's huge facility at Kattupalli near Madtas.Since the reactors are being built by BAARC at Kalpakkam, this facility would be ideal.A new naval.base near Madras is also being planned ,a second N-sub building facility is a must.

I see no other options. the old way of just shipping structures to vizag for total fitting out is not going to work.
someone has to do the complete fitting out and final assembly before perhaps sending it to Vizag to bring up the reactor and do testing.
or maybe just the full fitted out sections get finally checked and welded in vizag....and for that too a 2nd ship building hall and drydock will be needed.

I have been watching developments at Rambilli for some time on google earth and hoping that a bigger version of the SBC will also come up there.
I dont see any space for expansion of the present SBC at vizag due to space constrain unless navy is ready to give up the dry docks adjacent to SBC

Actually L&T itself is hesitant as far as nuclear submarine project is concerned as the lead integrator. They do not want to handle the reactor stuff. As a vendor supplying hulls, they are fine.

In fact I doubt if any private company will show much enthusiasm for lead role in nuclear projects(civil or military). Govt agencies will have to shoulder this burden for the time being

Indeed! I suspect we will never have a true SSN, like Seawolf/Nerpa, but more like the Virginia, with some land attack and more importantly, some stout mijjiles with anti-CVN capabilities :oops: :oops: :oops: . Wonder how many brahmos will fit in each UVLS? Five per UVLS with adapter, for a total of 20?

That will finally bury Philip-saar's dreams of a half-assed and expensive Amur design P75Is carrying a clip of 16 brahmos :D

IIRC, as per open source releases, SBC has space for (atleast) two boats to be worked on. This article from 2011, about that unfortunate incident of a gate mishap

Sources said India's first nuclear submarine INS Arihant is located in the same Naval Dockyard and another submarine was under construction, but these were unaffected by the mishap. Visakhapatnam is the headquarters of the Eastern Naval Command.

Since outsiders' entry is prohibited in the entire area, mediapersons were not allowed anywhere near the dockyard.


Rambili looks like a pure submarine base and maybe one of those special weapons storage and servicing center. The continental shelf drops off into the depths at 1.6 kms or so 8) So need to dredge a channel through

If this is the loc ( :lol: :lol: :lol: ), the pace started climbing rapidly up since 2017:

there were plans to excavate a cavern under that hill with a seaside entrance for subs to directly slide in without showing.
only a abandoned ussr base near sevastopol and allegedly the cheen SSBN base in hainan island has such deep secrecy.
muricans who are blessed with 18 huge SSBNs and 50 SSNs park them insolently and openly. mystic in CT has a impressive line of piers for SSNs to moor.

similar caving expertise may have been gained near vizag iirc where IOC stores gas in a huge stone cavern. was in the news few years ago.

actually looks like bigger play to store 5MT of oil in caverns not just LPG. and more in vizag and mangaluru are in progress

khan does that insolence in another way at Bremerton too, with this lazy "take your time" decommissioning/dismantling of older boats that are at least a generation ahead of the rest. Kind of loves rubbing it in, khan does to friend and foe alike. Hence the H&D salvage claims of Tempest as 6th gen et al :lol:

Some internal dhoti shivering when discussing our own strategic facilities is good, no?

Indeed, we have tremendous experience in digging caves and tunnels especially companies like HCC, L&T etc(although financial health of these companies is suspect.). We should definitely make use of this technical expertise for strategic and defence purposes.

arshyam, there are a plethora of articles out in the web in the past one month, that seem to throw aspersions on the seriousness of Indian second-strike capabilities, resolve of government to take the program to conclusion and even the recent announcement by Prime Minister about the first deterrent patrol was met with some derision about "ways to go" etc. Let them get back on what Rambili means : second strike that got proofed with the first patrol and a soon-to-be fully operational base.

As of now, there is nothing of interest overground there, except a dredger and some earth movement.

the cheen SSBN piers is a mirror image of the murican SSN ones in mystic

https://www.bellingcat.com/news/rest-of ... 094-ssbns/

094 "Jin class" is now 4 active, and 2 fitting out.

i have visited the uss nautilus and the adjoining naval museum , but never realized I was 500m away from the crown jewels!! thats chutzpah and khan-fidence, letting the unwashed hordes trample all around one of their most important base. they used to have a couple of naval ratings on the nautilus , young lads who gave you a stick with a recorded voice that described sections of the sub. the nautilus was old ww2 style not the albacore hull shape.

Cavern dug in vizag for petroleum reserves. This particular cavern was excavated by HCC.

Similar cavern in padur near mangalore

As you can see some of these caverns are absolutely massive with the capacity of atleast 4 trucks parked side by side. We have all this capability. I am not even starting into tunneling works done by different metro rail agencies all over the country.

Advantage of being surrounded by their own lakes. A big lake(Atlantic) on one side. An even bigger lake(Pacific) on their other side. Plus a doctrine which allows for the first use of nuclear weapons.

^Isn't two boomers and a leased SSN (chakra) berthing around lazily sunbathing in full view enough of "open veil" and making the maos shiver? (communist chinese wear mao suits, which start shivering when their wearers are fed doklas for example).

We are speculating from photos that Arighat is under the partial veil, Arihant is berthing lazily and Aridaman is out there oppressing the maos. But we could be completely wrong!

It could be that Arighat is berthing lazily and both Arihant and Aridaman is out there and the one under the veil is an altogether 4th SSBN being kitted out.

^^ Yes, we have no idea which is which. But showing a couple of subs openly could also mean that the other(s) is/are on deterrent patrol, or it's just a slice of the khan-like chutzpah Singha saar mentioned above ("here is a dhoti, wear it and start shivering").

If that's the Arihant, then INS Arihant is not 111m as listed in open source, since the Akula IIs are 113m . Arihant is a few meters longer.

I dont think thats the Arihant but a 120m sub with 8 tubes (akula is 113m and this one is longer at both ends of pic). you can even vaguely make out the outline of 4 more tubes after of the open tube. 2 door outlines clearly visible on our side and 2 would on other side being a inline single row design

gentlemen of the regiment, I present the ARIGHAT !! :twisted:

which means it either arihant inside the half open shed or 3rd sub.
