The Astra missile has undergone exhaustive testing; not everything is published in news articles. As of now, other than the Meteor, the Astra missile is the most advanced BVR missile in the IAF inventory. The reason is that R-77 and Mica are based on technology from 20 years ago. BVR technology has moved far beyond the basic techniques in these earlier missiles in datalinks, ECCM, seeker, processing speeds (hardware), software, target discrimination, etc.
Astra missile also has greater speed and range than R-77 and Mica.

How did you concluded SMART is from Shaurya , the Missile doesn't look



There is a lot of research going on in the background , they study about the , salinity , temperature and surveying the ocean frequently , those data's are available for Navy .

View attachment 61675


Why Super Sonic Missile Assisted Release of Torpedoe (SMART) will be a good platform for India.

Through SMART India will get long range ASW capability. Range of SMART is advertised as 650 Km but there are all the possibility that the range is even more. With other ASW platforms , like Kamorta Class Corvettes, P8I Poseidon , Underdevelopment ASW shallow water craft , Unmanned Underwater Vehicles and the most important Underwater surveillance system of Indian Navy will enable Indian Navy to target and destroy Chinese Submarines at long ranges.

India’s underwater wall is connected with US and Japanese SOSUS Underwater network. This will give India an ear warning of approaching Chinese subs even ling before it enters Indian ocean.

Indian Underwater wall might detect and triangulate an SSK diesel engine even if the submarine is 1000Km away in the Indian Ocean. As the submarines gets closer to SOSUS array many additional submarines sounds can be discerned eg SSN reactor water/steam circulation, generator gearing-electrical motor sounds from SSNs and SSKs, dropped tools and water swishing over the hull sounds. Cavitations sounds might be picked up from Chinese SSNs over 15 knots submerged cruising speeds and SSKs over 5 knots submerged cursing. Within 100km the diesel sounds of an SSK might reveal an individual SSK even identifying as SSK known to be captioned by a particular commander (may be judged by his maneuvering habits). Identification of submarine Type or actual submarine is much easier if there are already recordings of the submarines sound on an Indian super computer data base (Library).

So after the detection of Chinese Submarines it only need to press the launch button of SMART for welcoming Chinese subs . If we deploy SMART in Andaman India can takeout Chinese sub way before it entering Indian ocean.

Both these missiles has the same arrangement of parallelogram and trapezoidal shaped fins placed almost in the same place wet to the length of the missile. Just below is the solid booster.

Both Shaurya and K-15 has the same arrangement. If not a variant, the SMART missile uses elements from the Shaurya family of missiles.

Really? You have to know that acoustic signature is not fixed, it changes along with temperature, depth, salt, mechanic status, etc, etc. In order to get a certain type submarine's signature, you have to do the following:

1. the capability to follow the submarine through the whole journey;
2. during the journey, keep yourselves close enough to pick continue record of acoustic signature;
3. Get enough number of anti-submarine platforms to track your enemy's submarine activities through the whole year and keep doing so for years.
4. Have a precise ocean bottom map over the territories where your enemy's submarines patrol.



Unless you have a huge anti-submarine network of US which can track the rksubmarine from South China Sea, to pick up a submarine in the most busistest trait (273 ships per day) in the world? You need 2 things:

1. Magic;
2. Luck.
I think you are under estimating Indian capabilities and over estimating Chinese capabilities.I would think that the first work that would have been completed would be the feasibility of tracking and reliably locating an enemy submarine in real time.
Targeting of the enemy sub in real time is crucial to the success of the system.

What is the point in firing a torpedo riding piggy back on a missile to 650 or even 1000km if it cannot be practically used. We would not be firing the missile for Diwali entertainment. It would be a waste of money and time to develop a system which cannot be used. So I am confidently stating that DRDO has already worked out the targeting part. They are not fools to go ahead and develop the system without it being feasible.

The Chinese raise question marks on the viability of our system but expect the world to believe in their DF-21 anti ship ballistic missile. According to them it is a feasible and proven system. How real time targeting of moving enemy ships several hundred or even thousand km away is done.?.

You have to prove that India has all the necessary systems to achieve that capability. There is only one country in this world has that capability - USA, which took them decades and hundreds of billions dollars to build up with the help of her allies. And it costs them billions of dollars to operate it annually. I simply don't see India has that money and technologies to do that.

Targeting of the enemy sub in real time is crucial to the success of the system.
The question is: does India need such a system now?
Chinese conventional submarines have no real threat to India, simply too far geographically.
Chinese SSBN? Well, they don't even need to come out of their harbor to cover the whole India.

Do you even understand what we are talking about here?
Detecting a hostile submarine is different from recording a acoustic signature of a submarine. The former only needs a couple of ships to detecting while the latter need a huge NETWORK and YEARS OF DATA ACCUMULATION.

What is this related to our discussion. You can question anything about Chinese missile, but I didn't question anything about India's torpedo!

I believe that there are very good reasons to believe that the US and India are collaborating in the search for submarines of China and Pakistan. The US has already established the anti sub network as rightly stated by you and will provide India the data to make the system (missile launched torpedo) workable.

Is China not providing Pakistan with military grade GPS equivalent signals and other satellite reconnaissance data?. What is surprising if India and the USA work together to counter a common threat. Your question on accoustic signatures of submarines is answered.

Indian and American P8 aircraft are already working working together in many cases. As far as the Indian Ocean region is concerned, India has accumulated a large amount of data on factors like salanity gradient, topography of the ocean floor etc.

It will not be easy for Chinese submarines whether conventional or nuclear to enter the IOR without getting detected.

The fact that Chinese drones are getting heartburn over long range hypersonic missile torpedo tells me that it will be quite useful.
India has certain classified technologies, both Indian and American, which have been used to track Chinese submarines in the Indian Ocean region for a while now. I could care less if Chinese drones believe me or not.

Graphics giant Nvidia on Monday said that India's largest high performance computing-Artificial Intelligence (HPC-AI) supercomputer PARAM Siddhi-AI will use its technology along with indigenously developed HPC-AI engine, software frameworks and Cloud platform by the country's Centre for Development of Advanced Computing (C-DAC).

Nvidia said that the supercomputer will be based on its DGX SuperPOD reference architecture, a turnkey AI infrastructure, making it possible for organisations to install powerful AI supercomputers with extraordinary speed -- in many cases in just a few weeks' time.

"Nvidia is committed to supporting nations across the globe in their mission to advance the frontiers of AI-enabled research," Charlie Boyle, General Manager and Vice-President of DGX systems at Nvidia, said in a statement.

"The turnkey Nvidia DGX SuperPOD architecture is central to helping C-DAC deploy its supercomputer in record time. With this new AI supercomputer, C-DAC will be able to unleash AI innovation at incredible scale to help India address some of its most important challenges now, and in the future".

C-DAC said that the PARAM Siddhi-AI scalable infrastructure will accelerate experiments and outcomes for India-specific grand challenge problems in healthcare, education, energy, cybersecurity, space, automotive and agriculture.

PARAM Siddhi-AI will play a pivotal role in developing a vibrant ecosystem for research and innovation in science and engineering, it said.

"It will catalyse partnerships with academia, industry, MSMEs and startups," said Hemant Darbari, Director General, C-DAC.

DRDO readies for another missile test, this time it’s subsonic ‘Nirbhay’
Amid the ongoing India-China stand-off in Ladakh, the Defence Research and Development Organisation (DRDO) is preparing for yet another missile test — an 800 km-range subsonic ‘Nirbhay’ cruise missile — which is likely to take place by the end of October or in early November.

This test is likely to be the last trial before the ‘Nirbhay’ missile is inducted formally into the armed forces.

Since September, the DRDO has carried out multiple missile tests. The first test was that of the Hypersonic Technology Demonstrator Vehicle (HSTDV) on 7 September, and its success paves the way for missiles that can travel at six times the speed of sound, making India the fourth country in the world after the US, China and Russia to develop such technology.


This was followed by a test of the nuclear-capable ‘Shaurya’ missile on 3 October, and the supersonic missile-assisted release of a torpedo on 5 October. The ‘Shaurya’ missile is now ready for induction into the Strategic Forces Command (SFC), which handles India’s nuclear arsenal.

In the interim, a different version of the in-service surface-to-surface supersonic cruise missile Brahmos was also tested on 30 September. The DRDO has also carried out other tests, including one for the indigenous Anti-Tank Guided Missile (ATGM), besides a host of others.

Message to China?

Asked whether the back-to-back tests were part of the messaging towards China, sources explained that some of the tests were planned for earlier but got delayed due to the Covid pandemic, while in some cases the tests were scheduled for now.

“The missile tests were held up due to the Covid pandemic, even though the labs were working round the clock. These tests show that the DRDO is back to business as usual,” a DRDO source said.
