Unveiling India's Underwater Might: Hydrodynamic Testing Shapes the Future of Nuclear Submarines

The recent visit of Vice Admiral Srinivas Kalidoss (Retd), Director General of the Advanced Technology Vessel Programme (ATVP), to the Naval Science and Technological Laboratory (NSTL) in Visakhapatnam highlights the significant strides India is making in its underwater defense capabilities.

His inspection of hydrodynamic test models sheds light on the meticulous engineering and innovation underpinning India's naval ambitions, particularly within its nuclear submarine program.

The Science of Submarine Design​

Hydrodynamic test models are essential tools in submarine development. They allow engineers to simulate and analyze how different hull designs and configurations perform under various underwater conditions.

Factors like speed, maneuverability, stability, and noise reduction are all crucial elements that hydrodynamic testing helps refine. The result – submarines optimized for performance and operational success.

Beyond Replicas: Models and India's Nuclear Ambitions​

While these hydrodynamic models offer valuable insights, it's crucial to note they are not exact blueprints of the sophisticated submarines India is developing within its nuclear deterrent strategy.

The S4 and S5 SSBNs (Ballistic Missile Nuclear Submarines), in particular, are far more complex. These vessels are the cornerstone of India's Nuclear Triad, designed to operate across vast distances – a testament to India's technological prowess and strategic goals.

The Strategic Context​

The S4 and S5 SSBNs are a testament to India's commitment to a robust nuclear deterrent and maintaining strategic stability in the region. Their development reflects the evolving security landscape and India's resolve to meet potential challenges.

Hydrodynamic test models, while just one piece of this puzzle, are integral to ensuring these submarines possess the performance capabilities necessary to fulfill their critical role.

India's Naval Modernization​

The insights gained from hydrodynamic testing and the broader submarine development program contribute to India's ambitious naval modernization efforts.

As a major regional power, India is investing heavily in advanced naval capabilities to secure its maritime interests and maintain its strategic position.

Conclusion​

Vice Admiral Srinivas Kalidoss' visit to NSTL underscores the importance India places on its submarine force. The hydrodynamic models represent the scientific rigor and dedication behind developing submarines optimized for the nation's needs.

Within a larger context of nuclear strategy and naval modernization, these submarines are a crucial component in safeguarding India's security and shaping its role in the Indo-Pacific region.

Such information about nuclear submarines is definitely classified SUPER SECRET.
Any revealations of such information will be prosecuted and jailed for a long time.
How did he even open his mouth?

He could not take pics, nor did he take back any data. Anything he can say, is of no strategic value to our enemies.

Worked in classified areas for three decades so it is deadly sin to talk at all.
It gives our enemies clues about shortcomings of a nuclear submarine.
Not impressed at all.

It will take time to design and develop brand new nuclear submarines and on average it takes about 6-8 years just to design it and almost the same time to manufacture it unless it's a copy.

India has already got the first two Arihant submarines in service which are ideal to keep Pakistan in check as the longest range missile we can use is the K4 which gives us about a 4000km range which keeps our submarine out of range of anything that Pakistan can deploy.

The last 2 Arihant submarines are larger and longer so that we can install much longer range missiles which would be ideal to use against China as it can use the K5 which gives it a range of around 6000km.

The main submarines we need are at least 6 S5 class submarines which are double the size of the Arihant class submarines. This will give us the capability to hold and launch more longer range missiles which don't place our submarines too close to China. These are the type of submarines that we will need to meet future threats which will increase so we shouldn't build anymore Arihant submarines and they should be eventually retired in about 30+ years.

Shortcoming of military equipment is commonly discussed. Eg. Fighter having faulty engines, or missiles having accuracy issues, stealth aircraft haveing shoddy stealth. When you get into specifics and hard data, that is when it becomes dangerous. Just talking about classified stuff is not taboo, discussing classified stuff about classified stuff is wrong. I hope ypu get the difference

No, I do not get it as it is not acceptable practice when it comes to Nuclear Submarines.
You also mentioned the names of specific nuclear submarines INS Arihant and INS Arighat, a BIG NO NO.
Goodbye.

 

[Sathish Kumaram]

We need to aware of future potential threats of underwater drones and to be considered in designing new platforms

 

[Rational Guy]

well, russians helped out India for those reactors. Apparently you can find russian guys there permanently.

What's your source that Russian members are on Arihant?

 

[Rational Guy]

No, I do not get it as it is not acceptable practice when it comes to Nuclear Submarines.
You also mentioned the names of specific nuclear submarines INS Arihant and INS Arighat, a BIG NO NO.
Goodbye.

He also revealed we have coolant issues which means now the enemy knows that our subs will need extensive manufacturing and won't be at sea for extended periods of times

 

[Rational Guy]

Efforts should be first have enough conventional submarines, indigenous fifth generation fighter planes , armed drones , armed under water UUV's , nuclear submarine should come but at last.
And we have non but we are spending our efforts on those which will be used mostly never.

My sweet child, these things exist so that they will never be used

 

[Apocalypse gupta]

Apparently, poor state of technological advancement in a country which thinks it is still USSR, but has to make do with an economy the size of Mexico.

well, russia has stagnated, no doubt about that.

Yes, I mentioned above about revealing issues.
Too sad...

Loose Lips Sinks Ships.

 

[Apocalypse gupta]

I dont know exactlyl where russians are. I doubt they are part of crew. Most like they are stationed at the base. You can read my earlier comment about why I know this.

India only has 2 operational nuclear subs. So onviously I will name those 2. You are beingg paranoid for no reason
