Indian nuclear submarines

I HOW ABOUT INS MAHATMA GANDHI

That submarine will be unarmed and will come out in open and will broadcast to enemy subs about its location and will invite them to hit it with torpedoes. Just like that idiot....

It will ask Indian navy to get destroyed if enemy is coming to destroy you, but we can't retaliate, Ahimsa wadi

 

[Khagesh]

And why would they when their Jl-2 SLBM can target any part of our country without having to come all the way down to the Indian ocean?

I agree the SSBN will not but the Chinese SSNs will come into our oceans. That much is given.

Its about throwing a challenge when an SSN comes close. This is how countries fight, without actually firing in anger.

From the Indian perspective it would matter if Chinese SSNs do come in, unheard.

Chinese still have a ways to go before their SSN are quiet enough to traverse hostile seas. IMHO, their conventional submarines are a more immediate threat. Meanwhile, we need to up the military infrastructure on Nicobar. We need to have the capability to permanently base Kamorta class and P-8I as well as a submarine pen for our future indigenous SSNs and our current diesel-electric submarines. We need to expedite that underwater sensor array and completely dominate the stretch between Campbell bay, Banda Aceh and Phuket.

Sorry for off-topic post.

A bigger nuclear submarine is coming

Blue power: The nuclear-powered INS Arihant is seen off Visakhapatnam in this file photo.


After INS Aridhaman, focus will be on more potent version.
India’s second strategic nuclear submarine Aridhaman is just a few weeks from sea launch. But raising ambitions for the Navy’s capability, there are plans to build a bigger and more potent version of the indigenous nuclear submarine in the immediate future, say sources.

That leap for India’s ballistic nuclear submarine capabilities would come with the fourth submarine planned in the same class, named S4-Star. It would have a stronger weapons configuration integrated into an extra compartment that would be added to Arihant’s original design.

On the Aridhaman, sources said the “final checks are under way. All the three modules have been integrated. It is likely to be launched in late November,” an official source told The Hindu. Another source said a November launch may be difficult, but “in December, it will definitely be in the sea.”

Fuel loading in the nuclear reactor for Aridhaman was completed in January, but it would go critical only much later after initial sea trials. Once launched, the submarine will be put to extensive harbour and sea trials, before being formally commissioned in the next couple of years.

The indigenously built second nuclear submarine will add to India’s growing nuclear capabilities, in the face of the new strategic realities of the region, including the assertive Chinese naval presence in the Indian Ocean.

Last October, India commissioned its first Ballistic Nuclear Submarine, INS Arihant. The vessel, weighing 6,000 tonnes, is powered by an 83 MW pressurised light water nuclear reactor.

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.

Indigenous capability

The project to build a strategic nuclear submarine to carry nuclear missiles began as the Advanced Technology Vessel project in the 1980s, and the vessel project was launched in 2009 by Dr. Manmohan Singh.

Arihant, which can carry nuclear tipped ballistic missiles, is of the ship submersible ballistic nuclear class.

INS Aridhaman, Navy's Latest Nuclear Submarine, Set For Sea Trials


New Delhi, October 18: Indian Navy is all set to add more muscle and bolster its nuclear submarine fleet with INS Aridhaman, the country’s second strategic underwater warship, going for sea trials soon. Coming after INS Arihant, the 6,000 tonnes nuclear submarine commissioned into Indian Navy in August 2016, INS Aridhaman will also carry nuclear-tipped missiles after the warship is fully operational.

The two ship submersible ballistic nuclear (SSBN) submarines will give India the much-needed teeth to launch a retaliatory or second strike in case of nuclear attacks and also complete the country’s nuclear triad. Both the submarines have been built under the secretive Advanced Technology Vessel (ATV) project started in the late 1980s. The technology and design of Indian nuclear submarines are based on the Russian Akula class submarines. Indian Navy already operates INS Chakra, an Akula II class Nerpa leased from Russia.

INS Aridhaman is already undergoing finals checks and it is likely to be launched for sea trials in late November or December. The nuclear reactor which will power INS Aridhaman will go critical only after sea trials. The submarine will be formally commissioned into the Navy only by 2019. INS Arihant is powered by an 83 MW pressurised light water nuclear reactor.

Two more SSBN submarines under ATV project are already in the pipeline. With four nuclear submarines, Indian Navy will be able to truly project its blue-water operational capabilities.

The third submarine, which is likely to be launched in 2018, will have much more advanced weapons, systems and equipment than Arihant and Aridhaman, but will be of the same size as its predecessors. It will be followed by the fourth ballistic nuclear submarine with even more advanced weapons. The submarine will have an extra compartment to accommodate the weapons.

According to the Defence Ministry’s 2009 India’s Maritime Doctrine, “By virtue of its stealth and attendant survivability of second-strike capability, a nuclear submarine is particularly suited for nuclear deterrence.” The then Indian Navy Chief of Staff Admiral Nirmal Verma had in 2010 stated, “India’s nuclear triad is there when it (Arihant) is commissioned.”

INS Arihant will have the nuclear-tipped 750-km range K-15 Sagarika short range Sea Launched Ballistic Missiles (SLBMs) and the 3500-km range K4 SLBMs. INS Arihant can carry 12 K-15 SLBMs or four K-4 SLBMs which can be fired from four vertical launch tubes. On the other hand INS Aridhaman has eight launch tubes and will have twice the number of missiles in its belly compared to INS Arihant. The submarine also has six 533-millimeter torpedo tubes.

Apart from being a bigger boat, Aridhaman will use the indigenously-developed USHUS integrated sonar system and the Panchendriya sonar developed by the DRDO. The unified sonar and tactical control system, which can be used for underwater communication, will also help Aridhaman track and detect submarines, torpedoes and underwater obstacles.

Aridhaman is also much faster than Arihant. Powered by a pressurised water reactor, Aridhaman boasts of a seven-blade propeller with a maximum surface speed of 15 knots and 24 knots underwater.

With the commissioning of INS Arihant in 2016, India had joined a select group of five nations – USA, Russia, China, France and the UK to build and operate a SSBN. Along with Arihant, Aridhaman will ensure that India can challenge China’s growing naval clout in the Indian Ocean.

If S-4 Star is coming then we have 3 SSBNs right now in working 2 on Patrol and one on sea trail. S-2 INS Arihant, S-3 INS Aridhaman, on Patrol and S-4 INS ???, on sea trail and S-4 star same as Ohio class with 12 silos coming soon means near completion or ready to be launched. As per my knowledge one more SSBN is to be launched in November/December this year if this is S-4 star then GOI is definitely hiding GOOD NEWS.

And if it is true then whatever news is leaked, it is always a year or 2 late so when GOI excepts S-4 star commissioning it will mean we now have S-5 INS Avinash with 16 Silos..........

I hate to burst your bubble here but the big boys are still some time away.
have spoken to someone involved in designing the SBC where these submarines will be built, they're looking at building hoists & ship-lift systems capable of lifting 14000 to 20000 tonnes as of now. the S-4 Star and her sister will likely only start building around 2020 after the SBC is built in the next 3 odd years.

One question - Why does India want to lease Akula submarine when India is already building Arihant class submarine indigenously? As far as I see, Arihant = Akula made in India. (Akula was reverse engineered to get Arihant).

Thanks in advance

Reverse engineered ??

Arihant was built even before we got our hands on Akula. Sure it may have borrowed some design aspects from Akula with Russian help. But it's not a reverse engineered Akula.

On the contrary, the future SSN fleet may draw a great number of design inputs based on Akula class.

Ok, sorry. But why lease akula when we can make Arihant class submarine? The cost of Arihant is lower and we will have ownership too. Nuclear submarine lasts over 40 years. Why lease in such case?

Because Akula is an SSN which hunts other submarines and ships. While SSBN stays far away from hunting role.
