INS Arihant : Updates & Discussion

[DARKY]

The Indian Navy uses both Klub-S and Klub-N variants for the Kilo class submarines (known as the Sindhughosh Class in Indian service), additionally the P-75I will proboly be able to fire the Bhramos.
@Safriz

The INS ARIHANT class will have K series with K-4s already tested and ready to enter service. INS Arihant will enter service by late 2013 or early 2014 with the remaining Arihant class subs entering every subsequent year.It is complete, it has sailed under its own power and will begin sea trails in very early 2013.

It had its sea trials already 1st long endurance deep sea trial/strategic patrol trial was due... which was to take place early previous year but there was no other submarine which could chase Airhant.. now that Akula is ready and fully operational the deep sea trail must be underway If not already happened... the only last step left is firing of a SLBM which would happen later this year... It was also delayed due to lack of long range trails.. and would have happened in December last year If Akula was inducted in time.

Arihant is incomplete and nobody knows when it will be completed...
I was asking if India Currently has such capability?

The second submarine is having its systems integrated and you are talking of 1st The hull of the 3rd and 2nd was completed in 2011... by L&T.

The DRDO is developing a K-4 underwater-launched missile, which will have a range of 3,000 km. Developmental tests of the missile's gas-booster have taken place from a pontoon.
The Hindu : Cities / Chennai : DRDO plans another K-15 missile launch

The secret 'K' missile family
In a dramatic breakthrough in its nuclear offensive capability, India has successfully tested a submarine-launched ballistic missile (SLBM) with an eventual range of 3,500 km. Tested secretly off Visakhapatnam in January this year, the 10-m long and 1.3-m wide missile emerged from a pontoon submerged 50 m underwater and breached the surface. Painted black and white so that it can be distinguished in water, it has passed a critical parameter.

Named after India's missile man, former President APJ Abdul Kalam, the nuclear-tipped K-4 is quite significant in a batch of new-generation counter-strike strategic missiles. The top secret indigenous "K" missiles are faster, lighter and stealthier. They also make India only the sixth country to develop undersea strategic missiles.
A second firing, to be conducted off Visakhapatnam within two months, will revalidate a critical parameter-the ability of a 20-tonne projectile to withstand 50 kg of water pressure and eject from a submerged launcher before engaging its rocket booster. What makes an SLBM relevant in the Indian context is that it is part of the third leg of the nuclear deterrent (air and ground-launched weapons being the other two) and the ideal invulnerable second strike weapon stated in the nuclear doctrine. Defence officials say a long range SLBM like the K-4 will enable an Indian nuclear submarine lurking in the Bay of Bengal to target China and Pakistan simultaneously. Launched last year, India's first indigenous nuclear-powered submarine Arihant has been designed to carry four K-4s or 12 of the 750-km range K-15s.

DRDO officials say that the K-4 will be ready for induction before the end of the decade. This is because most technologies, including the sophisticated guidance packages, were already perfected while developing the shorter range K-15 SLBM. Defence officials, however, are cautious because despite a history of missile expertise, Russia has witnessed multiple failures of its new Bulava SLBM. In the works is an as yet unnamed longer-legged variant of the K-4 with a 5,000-km range. The 12-m long missile is meant to arm future nuclear submarines.

But while the DRDO parades its Agni and Prithvi missiles on Republic Day, it will not even acknowledge the existence of any of these "black projects� that have been cloaked under the Advanced Technology Vessel Project (ATV) that builds the Arihant class of nuclear submarines.
The secret 'K' missile family : The Big Story - India Today

India to test a submarine-based ballistic missile
India's Defense Research and Development Organization (DRDO) started preparations for test launch of a submarine-based ballistic missile (SLBM), reports Express Buzz. The missile will be launched from underwater position off the Andhra Pradesh state. Expectedly, the trials will be held in Jan 2011.

DRDO does not specify which missile is to be tested. At present, India develops two missiles of this class – K-4 (Agni-III SLBM) and K-15 (Sagarika). As for directors of test range Chandipur, the new SLBM will be launched by underwater stand which is almost identical to submarine.

Tests of K-type ballistic missiles will be carried out by above mentioned stand for next several years, since the country does not have a missile-tubed submarine so far. In prospect, trials will be held by Indian nuclear sub Arihant launched in 2009; the sub is to be commissioned in 2011.

According to DRDO, both K-4 and K-15 SLBMs are absolutely ready for tests. K-15 Sagarika will be armed with a 1-ton warhead capable to destroy targets at 700 km. The missile has a weight of 17 tons; its length is 10 meters and diameter is 0.74 meters. It is known that ground-based variant of the missile (Shaurya) is being developed on the basis of K-15.

Being a naval version of ground-based Agni-III SLBM, K-4 will be armed with 2.5-ton warhead capable to destroy targets at the distance up to 3,500 km. Other specifications of this missile are undisclosed so far. Reportedly, it will be smaller than Agni-III and armed with nuclear warheads (yield of 200-250 kiloton).

DRDO developing missile capable of carrying multiple warheads
While the length of the missile would be reportedly around 40 meters as against Agni-V’s 17.5 meter, its diameter will be 1.1 meter, which is almost half of Agni-V. The missile’s launch weight would be around 55 tonne.

The ICBM Agni-VI is said to be the latest and most advanced version among the Agni series of missiles. It will have the capability to be launched from submarine and from land-based launchers. The DRDO is also working on integrating Agni-V with submarine.

This info about K4 launches was leaked by some navy officers on Facebook & was posted on this very forum as well. Later there was discussion in a thread as well right here.

I know few more things but as OSCAR sir said it's always better to hide these things on public forums.(It is idiotic to leak out ANY information without checking with your superiors first or verifying that the information is available publicly.(a different thing if the public inflates the info for their own appeasement.)

This is the first video of the test of Indian K-15 SLBM made public ! This is the 14th successful test of this great SLBM...which now completes the Indian nuclear triad by getting operational..this would now be integrated with INS Arihant ! JAI HIND !
This is the first... | Facebook

K-15 SLBM a beast loaded with gen-next tech: Scientists
The scientists at Defence Research and Development Organisation’s (DRDO) Missile Complex in Hyderabad are an inspired lot, thanks to the successful test (14th) of the 750-km range submarine-launched ballistic missile (SLBM), K-15. The missile (codenamed B-05), was tested for its full range from a submerged pontoon, off the coast of Vishakapatanam on Sunday.

Sources in the Missile Complex told Express that K-15 was launched from an underwater vehicle with an approximate depth of 50 metres. What adds teeth to the killer missile is the array of gen-text technologies that are embedded onboard, a majority of features till kept under wraps. “The medium range missile, with a capacity to be launched from multiple platforms has so far undergone many trials. It is primarily employed against land targets. The missile is incorporated with high accuracy navigation systems with completely different and specific schemes, that can steer the vehicle towards the target with single-digit accuracy,” sources said.

The scientists have designed special alignment techniques with most modern algorithms which are specific to underwater missions. “We have used most modern computing and actuating systems. The missile has a two-stage booster, with one being employed underwater and the other above the surface. The underwater dynamics are totally different from the aerodynamic environment. Here the hydro-dynamics come into the picture and many factors like water pressure, wave speed, direction and many more have to be taken into account,” sources said.

The K-15 missile is ballistic, but travels through the atmosphere all through the mission. It is controlled and guided all through by onboard guidance computer system. The missile now enters probably its most-critical phase, when it will be integrated with India’s first home-grown N-powered submarine INS Arihant, which is warming up for its maiden sea-acceptance trials.

“Though we have more trials on the naval platform, the missile will still get into the production mode. Once the Indian Regional Navigation Satellite System goes live next year, all our future missions will have pin-point navigation support,” sources said.

Speaking from Hyderabad, Defence Research Development Laboratory (DRDL) Director and K-15 Programme Director A K Chakrabarty said his team had a challenging job on hand.

“When you execute underwater missions, the rules of the game changes. While launching the missile (from a submarine) nothing should happen to the platform, considering it’s a manned one. Hence, it was a huge challenge to our designers,” Chakrabarty said.

Over 200 scientists and officers from five DRDO labs, including DRDL (Hyderabad), Research Centre Imarat (Hyderabad), Advanced System Laboratory (Hyderabad), R&D Engineers (Pune) and Interim Test Range (Balasore) are involved in the K-15 project.

INS arihant might enter service in the 1H2013.

Defense Minister A.K. Antony told India’s parliament last May that Arihant might enter service in the first half of 2013.

This capability would complete India’s nuclear triad, making the country capable of launching missiles from air, land and sea. The triad’s other elements are the Agni missile with a range up to 3,106 mi., and the Mirage-2000, Su-30MKI and MiG-29 fighter

INS Arihant, India’s N-powered submarine, to be operational this year end ,will go critical in 2-3 weeks

In a big step towards securing India’s nuclear deterrence capabilities, the reactor on board the indigenously built nuclear-powered submarine INS Arihant is set to become operational within three weeks. The submarine, which is over 100 metres long, has been undergoing trials in Visakhapatnam for the last three years .

Dr VK Saraswat, the chief of the Defence Research and Development Organisation or DRDO, shared these exclusive details with NDTV. He said that once the Indian-made enriched uranium nuclear reactor – which has been in development for two decades – becomes operational, INS Arihant will be ready for sea-trials and will subsequently be commissioned.

The induction of INS Arihant into the Indian Navy’s fleet will complete the crucial link in India’s nuclear triad – the ability to fire nuclear weapons from land, air and sea. So far, the US, Russia, France, China, and the UK have the capability to launch a submarine-based ballistic missile.

Though this comes as good news for India’s defence capabilities, there is some concern over the overall strength of India’s submarine fleet. India has 14 conventional submarines that run on either battery or diesel and are aging and outdated. Each of them will have completed the standard life-span of 25 years by 2017.

Great News!! After a long time. Building a Nuclear Sub which is more complicated than LCA and that too at the first attempt is a great achievement. It will give us a chance to give a bloody nose to our adversaries (i.e 2nd strike capability). IAF should learn from IN.

INS Arihant reactor to be made critical next week

NEW DELHI: Moving towards completing its nuclear triad, India will activate the atomic reactor on-board the indigenous nuclear submarine INS Arihant next week paving way for its operational deployment by the Navy soon.

"We are gearing up for the sea trials of Arihant," DRDO chief V K Saraswat said today at an award function here.

"The nuclear reactor on-board the INS Arihant would be made critical (activated) in first week of June," sources said on the development of the nuclear submarine.

Nuclear triad is the ability to fire nuclear-tipped missiles from land, air and sea. After the nuclear reactor is activated, the agencies concerned can work towards readying the warship for operational deployments soon.

INS Arihant has been undergoing trials at Navy's key submarine base in Vishakhapatnam and would be launched for sea trials after the nuclear reactor goes critical.

The DRDO has also readied a medium-range nuclear missile BO-5 for being deployed on the Arihant and its last developmental trial was held on January 27 off the coast of Vishakhapatnam.

The nuclear submarine will help India achieve the capability of going into high seas without the need to surface the vessel for long durations.

Conventional diesel-electric submarines have to come up on surface at regular intervals for charging the cells of the vessel.

Indian nuclear submarine INS Arihant features environment friendly water mist fire suppressants

New Delhi: INS Arihant, the Indian nuclear submarine features Defence Research and Development Organisation (DRDO) made water mist fire suppressant instead of the ozone depleting Halons. CFEES (Centre for Fire, Environment & Explosive Safety), a DRDO unit has designed and tested generation of water mist to fight pool fires. A water mist fire suppression system generates water droplets to sustain fire sprinkler system with the help of nozzles.

The DRDO technology was validated for INS Arihant submarine in real scale 590 m3 cylindrical submarine fire simulation chamber. The simulation chamber was simulated as nuclear submarine compartment having four decks.

The pool fire and spray fire different heat release rate was created inside the chamber and suppressed with water mist system having internally mixed atomizer as mist generator. The validation was successfully carried out as per IMO Circ 1165.

The technology has been accepted by Indian Nuclear submarine program, the Advanced Technology Vessel program (ATVP), for induction in S3 and S4 submarines as a replacement to Halons.
