Indian nuclear submarines

[sayareakd]

Project K is interesting, these are all the strategic programmes that Dr. Kalam thought necessary for India, what is most interesting is the fact that, we know existence of only K15 and K 4, so there exists K1 to k3 and K5 to K14 at least, that is one way of looking at things other way is that it would be bad idea to name the project after numbers, as it would give idea to others how many things you have cooked, if some rival intelligence agency want data they would know exactly what to look and ask for. BTW lot of misinformation and name changing is going on with DRDO they have bad and old habit of playing with names.

dove you are partly right, but need to know that modern sub hunters work very efficiently, but they are not jet power aircraft and helicopters, therefore modified Python-5 with 20km range is good missile against these aerial threats, when the hunter will suddenly become hunted. BTW think of tow equipment for sub.

Some Interesting development by DCN..
Looks like French are making Submarine launch MICAs..

Submarines are probably Scorpions..

SSBN Arihant On Deterrent Patrol With Strategic Nukes By 2012: Navy Chief

India's nuclear triad -- a matrix of weapons delivery systems from land, air and sub-sea -- will be complete with the commissioning of India's first SSBN, Arihant in 2011-2012. In a significant comment at his annual press conference today in New Delhi, Indian Navy chief Admiral Nirmal Verma categorically stated that when the Arihant is put to see in two years, it will be on deterrent patrol with strategic weapons on board.

In a year, India will have nuclear triad: Navy chief

NEW DELHI: Only three countries, US, Russia and China, can be said to have fully-operational nuclear weapon triads -- the capability to fire nuclear-tipped missiles from land, air and sea. India will gatecrash into this highly-exclusive club by 2012.

Navy chief Admiral Nirmal Verma, not given to making dramatic statements, said the triad will be complete once its crucial underwater leg, the country's first indigenous nuclear submarine aptly named INS Arihant or the "destroyer of enemies", is commissioned towards late-2011 or early-2012.

The land and air legs are already in place with the Agni family of road and rail-mobile ballistic missiles as well as fighter jets like Mirage-2000s and Sukhoi-30MKIs jury-rigged to deliver nuclear weapons.

"When INS Arihant goes to sea, it will be on a deterrent patrol (read armed with nucelar-tipped missiles). The triad will then be in place... the aim is to make it as effective as possible," Admiral Verma said on Thursday, in the run-up to Navy Day on December 4.

This comes barely a day after Wikileaks revealed that American and European diplomats were greatly alarmed about Pakistan's feverish production of nuclear weapons. Estimates show Pakistan already has around 70 to 90 warheads, higher than India's 60 to 80. China, of course, is way ahead with around 240 warheads.

While Pakistan is nowhere near getting a nuclear submarine, China has 10 of them in its 62-submarine fleet, with three of them being SSBNs (armed with long-range strategic missiles). India, in contrast, has just 15 conventional and ageing diesel-electric submarines.

Consequently, INS Arihant is crucial to India's nuclear deterrence doctrine, which revolves around a clear "no-first use" policy. A robust and survivable second-strike capability is hugely dependent on having nuclear-powered submarines, armed with SLBMs (submarine-launched ballistic missiles), which can operate silently underwater for several months at a time.

Admiral Verma said INS Arihant, which was "launched" at Vizag in July 2009, would have potent SLBM capabilities to complete the triad. With INS Arihant's miniature 83 mw pressurised light-water reactor slated to go "critical" within a month or two for sea-acceptance trials, Navy also seems quite confident about ongoing undersea tests of the 700-km K-15 and 3,500-km K-4 SLBMs.

The 6,000-tonne INS Arihant, which has four silos on its hump to carry 12 K-15s or four extended range K-4s, is to be followed by another two nuclear submarines under the secretive Rs 30,000 crore Advanced Technology Vessel (ATV) project.

Navy, on its part, wants to have three SSBNs and six SSNs (nuclear-powered attack submarines) in the years ahead. The force will also finally induct the K-152 Nerpa submarine, on a 10-year lease from Russia, towards April-May 2011 after several delays.

While the 12,000-tonne Nerpa will not come armed with long-range missiles due to international treaties, it will help train Indian sailors in the complex art of operating nuclear submarines. It will also be a lethal hunter of enemy submarines and warships, armed with torpedoes and 300-km Klub-S cruise missiles.

'INS Arihant' to sail on deterrent patrol after commissioning

Sandeep Unnithan | December 2, 2010 | Updated 16:40 IST

India's first ballistic missile submarine the INS Arihant will go on "deterrent patrol" or sail with a full complement of nuclear-tipped missiles when she is commissioned in 2012. "The nuclear triad will be there when it is commissioned," navy chief Admiral Nirmal Verma said at a press conference in New Delhi.

This is the first time a service chief has commented on the deployment of a nuclear weapon platform. Launched last year, the Arihant is the first of a series of five indigenously constructed ballistic missile submarines (SSBN). The Indian SSBN is meant to form the third and most survivable leg of a troika of land, air and sea-based platforms enunciated by the Indian nuclear doctrine. The submarines are being constructed at the high security Naval Dockyard Visakhapatnam. "We expect to have it going in two years, end 2011 or 2012," Admiral Verma said. "We are going with the float as far as things go," he said in an attempt to answer speculation that technical glitches with the submarine would delay its commissioning.

Deterrent patrol means a long and lonely vigil where the submarine sails submerged and undetectable for weeks on end with its load of nuclear weapons. It is meant to 'deter' an adversary from launching a first strike on the nation. Only four nations-the US, Russia, France and UK have SSBNs sailing on deterrent patrols. China has two SSBNs and is building three more but its submarines have never sailed on deterrent patrols.

Admiral Verma's predecessor was the first to confirm the existence of the highly classified Advanced Technology vessel (ATV) project two years back. Security analysts however believe that the navy chief's estimates of induction could be optimistic. The Arihant is yet to begin her sea trials or even fire up her nuclear reactor. Missile tests will follow after the submarine completes her sea trials which could take up to a year. Two nuclear-tipped missiles are being developed for the Arihant class. A 700-km submarine-launched ballistic missile (SLBM) called the K-15 or the B-05 has been tested eight times and is in serial production. A 3500 km SLBM, the K-4 has been tested once and will be fielded by around 2017. A second test of the K-4 is expected in the next two months.

Sandeep Unnithan is the journalist , who first broke the news of existence of K4 Missile.

I find this post perplexing - If the K4 is being tested now.....then why will it take 7 years to be fielded.

Also what good is a 700 mile range SLBM. That means that your submarine will have to be parked within 100 or 50 miles off the enemy coast to hit any of the enemy's inner cities, and that would make your Boomer a sitting duck !

So what is the point of an SLBM with a 700 mile range ??

 

[Yusuf]

That is a pak specific missile matt. that range is enough for that country.

As you know SLBM is very complex piece of technology and our SSBN technology is also not field tested. So isn't it be intelligent to allow the SSBN, SLBM and command and control network to get mature before putting them together? I think, it for the safety and robustness that they had fixed 2017 for inducting a +3500 KM range SLBM on a new SSBN (which by then will be mature platform).

Actually K-15 was a technology demonstrator for SLBM. Initially it had only 100-150 KM range. Tt was only when those special and unique SLBM technologies got proven then they increased its range to some usable level i.e 700 KM which brings many of important targets in pakistan within striking radius. Nevertheless DRDO wanted something to start with and a 700KM range SLBM is not that bad at all.

As an engineer I thought about nuclear vs diesl/electric sub. What are the pros and cons?

When MovingBoth leave a wake, even when submerged. Not too hard to detect in these days of hi tec gadgets. In addition both leave a magnetic plume too.

Score even

Submerged and stationary

A nuke sub has a reactor which is active at FULL 24 hours. It ejects a lot of lot of heat. In addition, the nuclear subs are "noisier". Why? D/E sub has only to move its housekeeping machinery. A nuclear sub has nuclear engine to contend with and MUFFLE. If you are an engineer like me me, you should know it is a VERY tall order.


The only plus point for a nuclear is that it can act as a long range interdictor. Does IN need such a ship against Pakistan or China? How long will it take US Navy to detect such Indian subs and blast them?

I know, I know. You can say I am a CIVILIAN. But remember, I deal with large hydel turbines. They suffer erosion, called pitting. It is due to cavitation when a body moves in a fluid. There is NO theory to predict whether cavitation will or will not happen, agreed. Quantification is a far CRY. But I do know turbines and other hydraulic machinery. And propellers are turbines for me. AND cavitation is a FACT.

Kunal check this

IDAS (Interactive Defence and Attack System for Submarines) is a short-range missile currently being developed for the new Type 212 submarine class of the German Navy.
IDAS (based on the IRIS-T air-to-air missile) is primarily targeted against air threats, such as ASW helicopters, but also against small or medium-sized surface vessels or coastal land targets. It is currently being developed by Diehl BGT Defence and HDW, which is a part of Thyssen-Krupp Marine Systems (TKMS), to be fired from Type 212's torpedo tubes. IDAS will be fibre-optic guided and officially has a range of approx. 20 km. [1] Four missiles will fit in one torpedo tube, stored in a magazine. First deliveries of IDAS for the German Navy and operational service are planned from 2014 on.[2]
The IDAS system is also the world's first[citation needed] missile which gives submarines the capability to engage air threats, and the first tube-launched missile that does not emerge in a capsule, but is fired directly from the torpedo tubes.

Indian Navy accelerates Nuclear Submarine programme

According to well placed sources, while work on Arihant, the first nuclear submarine that was launched in 2010, was going on as scheduled, construction of the hull and sub components of the remaining two submarines was also underway. Considerable experience has been built from the development of Arihant, and the successive two submarines would be successively more potent with more power and punch.

DRDO must understand that we already have overkill measures to stress Pakistan out and there's no point of targeting them anymore unless and until something can be done about their nukes which is not possible by us. This means that we need SLBMs to specifically deter the larger neighbour. any Chinese city from Bay of Bengal in India:

And knowing our government that cannot even face Sri Lanka straight, I doubt that Verma has any plans to send the Arihants to South China Sea. So what will a 700 km SLBM do? If Arihant stands on the coasts of Bangladesh, we might be able to strike Lhasa at the most which is no use since ruining Tibet is not the aim at all; for any strategic deterrence, Beijing, Shanghai, Guangzhou, Hainan, Chengdu, Wuhan etc are to be the targets. What will nuking an already desolate and innocent Lhasa do?

DRDO should stop wasting tax payer's money on making a damn missile for every single kilometer in the sequence (first 100km then 200km, then 500 km, then 700 km).

Opposed to what is claimed by our media, this sort of slow and hesitant approach to put Beijing and Shanghai on our nuclear radar shows that the government is still Pakistan-focused rather than China-focused and that MOD and its backers lack the courage to stand up.

 

[sayareakd]

@Tshering22 if DRDO start making things without GSQR or other services requirement then CAG will kill them.

all the system are made after the getting the requirement from the services.

The current Arihant is Pak specific.
