India's Two New SSNs to Boast 10,000-Ton Displacement, 40% Bigger Than Similar Chinese Type 093 Shang-class Subs Deployed in IOR

NEW DELHI – India's ambitious nuclear attack submarine program has taken a significant leap forward with the recent Cabinet Committee on Security (CCS) approval for the construction of two new SSNs.

Reports from Times of India indicate these submarines will displace nearly 10,000 tons, making them substantially larger and potentially more capable than previously estimated.

This places them in the same league as the US Navy's formidable Virginia-class Block V submarines and significantly ahead of China's Type 093 Shang-class SSNs currently deployed in the Indian Ocean Region (IOR).

These new submarines will be 40% larger than China's Type 093s, which displace around 6,400 tons. This size advantage translates to increased endurance, allowing for longer patrols and potentially greater weapons payload.

Experts believe the submarines will be equipped with Vertical Payload Tubes (VPTs) capable of housing a variety of advanced weaponry, including subsonic cruise missiles like the Nirbhay and potentially hypersonic cruise missiles currently under development, such as Project Vishnu HCM or BrahMos-2K.

The ability to deploy hypersonic missiles, which travel at speeds exceeding Mach 5, would give India a significant edge in both offensive and defensive capabilities within the region.

These missiles are extremely difficult to intercept, providing a credible deterrent and enhancing India's first-strike options. In addition to cruise missiles, the submarines will also be armed with heavyweight torpedoes for both anti-ship and anti-submarine warfare.

India's focus on developing a robust and technologically advanced submarine fleet is seen as a direct response to China's growing naval presence in the IOR.

Beijing has been increasingly assertive in the region, deploying its own nuclear submarines and surface vessels. These new Indian SSNs, with their enhanced capabilities and advanced stealth technology, are expected to play a crucial role in maintaining India's naval dominance in the region.

The development of these 10,000-ton nuclear attack submarines also sets the stage for India's next-generation S5 class of nuclear-powered ballistic missile submarines (SSBNs). Projected to displace 13,000 tons, the S5 will follow the S4 and S4* SSBNs, which have a 7,000-ton displacement.

Both the SSN and S5 programs will utilize 190 MW pressurized water reactors (PWR) and feature modern pump-jet propulsion systems for enhanced quiet operation.
 
There is a factual error in reporting S4 and S4* submerged displacement as 7000 Tons. This figure is correct for S2 and S3 (Arihant and Arighat respectively); both S4 and S4* are stretched version of Arihant class with submerged displacement of 8000+ Tons.
As of now, India has two options for the planned SSNs; one based on Arihant platform with the same propulsion reactor (86 MW thermal) but fine tuned for the specific requirements of SSN such as higher maximum underwater speed. The second option is one based on the S5 platform, again the 190 MW thermal propulsion reactor of S5 will need to be fine tuned for SSN. The big difference is that the Arihant reactor is proven, S5 as yet is not proven. We ought not to forget that every new design is unproven till first used, Arihant reactor and the entire platform was also not proven till Arihant was commissioned and deployed. This is true for any new design anywhere in the world.

The decision for initial sanctioning of only 2 number of SSNs and 3 number of S5 class SSBNs is correct. Lot of new technologies are emerging. Pump jet propulsion is one which has been deployed by all other countries possessing nuclear submarines. All electrical propulsion instead of the conventional one used in nuclear boats utilising RIM motor is another. There are many more. We ought to try to modify the design to absorb these technologies midway in the programme rather than waiting till the next generation of boats.
 
WOW!! Astounding piece of news on paper while in performance.... well we all know about performance. MDL is what HAL is, inefficient. Hope the naval planners will keep a decade of buffer in cost escalation as well as delivery dates for delivery delays by MDL & plan accordingly.
Typical French propaganda.

We know the French role in cost and schedule overruns in Scopenes. Even the tech transfer hasn’t been smooth to say the least … that’s been the case with most of western purchases. But French has been notorious in this regard.
 
Nuclear attack submarines are a critical requirement for our navy as we need large and very fast submarines to cover the Indian Ocean and South China Sea. This submarine will be around 10000T big which is essential so that it can carry more heavy torpedoes and different types of cruise, subsonic and hypersonic missiles.

As for China's nuclear submarines which one of them sank before they had even finished developing their own technology and capabilities which doesn’t inspire any confidence to their poor technology and how’s it’s unreliable, faulty, problematic and dangerous.
 
What a condescending comment without any basis. It is a typical anti national attitude fully knowing that security wise Bharat is in a weak position where fighters & subs are concerned. He is right except the awareness of making of a nuke sub by India. ATV was really a open secret for a long time (couple of decades) which made US pressurise Russia not to collaborate.
I meant secretive as in the actual specifications were released only around 2009 in the public domain. Of course, in the geopolitical arena, it would have been known far sooner, as you pointed out.

They may not have experience or technology of Americans or Russians but they are improving their technology and eventually may better or equal them.
 
10000 t ssn can't believe it because till recently it was a 6000t ssn. Anyways it is not from any official channel or source but the usual propoganda stuff. 190 mw for a 10000 ssn🤔. 6000 is too small for vls in the era of hypersonic cruise missiles usage,maybe a 8000-8500 like the russian yasen-m ssn.

yasen class is 14k ton submerged
 
Your "please" will not work with MDL.
First and foremost, it's SBC at Vishakapatnam, not MDL, "please" get your facts right....

And despite the previous delivery history with DPSUs, as a general public paying huge tax, there's nothing wrong in hoping for quick delivery...

and lately lot of bashing to HAL? You got disinvested or what? Lol

Their recent nuclear attack submarines that has sunk now show and prove otherwise. They claim a lot but in reality their technology, equipment, weapons etc are not as good as they like to claim.

Why is bro hating when we ourselves do not have one of our own, at least China has indigenous manufactured Nuclear subs

We have nuclear submarines already. Their submarines aren’t as good as they say it is as their technology is unreliable, faulty, defective and underpowered than what they say it can do. They have complete control of the media so they never allow people to highlight the problems and defects in their projects or weapons which occur regularly. One of their brand new nuclear submarine sank while it was in harbour.
 
May be after this 10,000 ton class submarine deploymet, China will feel the heat and accept India also as a super power on par with it and will acknowledge it and accept giving permanent member to India in UN.

If not, then India will screw China after its next version. he he.
Chinese netizens have long believed that India is a superpower second only to the United States, and by 2030, India will surpass the United States
 
There r two types yasen and yasen-m.
There is only one submarine of 855 class rest all operational or under construction are 855m and they are 13.4kT submerged , Laika-class which is successor sub of Yasen-m will be shorter lighter and faster with 11-11.5kT submerged , expected to enter service by 2035 onward

BTW: India is already one of the five permanent members of the UN Security Council on YouTube.
