hinmoy, post: 1436634, member: 16906"]Mr Intelligent.............. Open your eyes and look back few pages. A2 was inducted in service during NDA rule in 2001. But after that too it had undergone development. Its design was not freezed after induction. Where I said that its development were only after 2010? Could you dare to pint it?
I simply gave the 2017 failure as example of user trial failure when member Kshithij's claim that India has no user trial failure. You jumped in and gave me a "Do you know" series with a assumption "Of course you don't know". You better re-read what I said. I only answer your question by pointing out all these "Do you know" updates happened before 2010, so EVERYBODY KNOW. Then I asked you what is the new development involved in 2017, you haven't given any answer yet.
Please don't put words in my mouth. Where did I say anything about "original design was implemented after induction"?
Ok, we should sort out the series tests of Agni-2 before any further discussion.
1. The production was only started after 2004 test not 2001;
2. There was no new development on the missile tested in 2004, the so called “enhanced range” was within the original design requirement;
3. There was no test after Aug 29, 2004 until May 2009;
4. The first user trial happened in May 2009, failed. There was no new development in the tested missile as this missile was RANDOMLY selected from the army’s pool of missiles to conduct “a repeat launch”.
5. The second user trial failed in Nov 2009. Again, the purpose of this test was to validate procedures for night firing, there was no source suggesting the “new navigation system” integrated. Both failures were due to the
6. After these 2 successive failures, the Agi-2 successfully tested in May 2010, Sep 2011, Aug 2012, Apr 2013 and Nov 2014.
7. Then, again, there was no test until 2017, very strange.
8. The missile with new navigation system and enhanced range was Agni-II PLUS, which was tested in Dec 2010 with a failure, but later continued with name Agni-IV.

So, form the history of Agni-2 tests, we can find the problem: the operational missile wasn’t tested every year. For the first break (2004 – 2009), it can be explained with production problem. But between 20014 and 2017, there was no test again, and the next test in 2017 was a failure. Then you have to question about the battle readiness of the missile group.
This conclusion is correct only when you take a very small forward step each time.
Wrong. Generally, for any weapon, there are two stages:
1. Technic verification: the verification of blueprint. This stage is to prove the design of the weapon has satisfied all the customer requirements. R&D deportment is responsible for this part;
2. Production verification: this part is the responsibility of manufacturing department, they have to setup the production line specific for this weapon, design/install new machine for new components, design new processing procedures/new standards. In one sentence, it is their duty to sort out all potential issues affecting quality. That is where the most quality problems occurred.
If we use Agni-2 as example, the 3 tests between 1999 and 2004 were technical trial to verify the design. Then it entered the production stage. Obviously, it took India quite long time to complete the production line and produce the first batch of missiles. But it is understandable since at the time India was still at early stage of missile development. And it is also understandable that first 2 tests failed for a new product. Thereafter, we can see the quality improved with next 4 successes.
But the question came up with the next few years: there was no test until 2017. That was strange because generally armed force should test a random example in every production batch. This is the necessary step to keep the production department in check.
There are also some quality issues caused by the daily storage and maintenance. That is why military need to test a random example from certain aged stock at least once a year. Most of the quality issues only expose during the flight.
So, you can see, experience can certainly help improving quality, but periodic test is far more important.
Firstly, you are not developing the sub components from scratch as you already accessed Russian sub-components and their blue prints for at least production purpose.
Secondly, the fact that the new indigenous components are fit back in the existing Brahmos design instead of next generation Brahmos tells me it is based on Russian blueprint because:
1. This datalink, data format, transferring rate, working model, even the shape/weight of this indigenous component must match with other Russian component. You can’t change them. When these were decided, there is no much for Indian scientists to develop;
2. From the designer’s perspective, there is no need to develop a completely new Indian seeker for an old missile, it is just like spending all the time/money to develop a 486 CPU with the purpose of fitting into a 286 PC, it doesn’t make sense economically.[/QUOTE]
You would not have written such a useless long response if you would have followed up the Missile development programme of India. For a layman like you, let me give a brief history of Agni series and specific reasons for coming up with different versions and what improvements been made in each of these.
Agni 1 : Just a tech demonstrator. It was designed to conduct and demonstrate Re-entry technology.
Agni 2 : Project to envisage Industrial capability buildup.
Agni 3 : Project to implement new building blocks in missile tech like Maraging steel and composite motor rocket engine for lighter missiles and longer range.
Agni 4 : Project to implement accuracy over longer range for delivering lower payloads for higher effectiveness. Components like Ring Laser Gyro were first time integrated and tested in it.
Agni 5 : Project to realize a true ICBM buildup capability.
So basically A1 and A2 were tech demo rather then full fledged system. Now lets have a look at test launch for each of them.
A2 first test on 1999
A2 second test 2001
A2 third test 2004
A3 first test 2006
A3 second test 2007
A3 third test 2008
A2 forth test 2009
A2 fifth test 2009
A3 fourth test 2010
A2 sixth test 2010. This was A2 prime which was later classified as A4.
A2 seventh test 2011.
A4 first test 2011
A 5 first test 2012
A2 eighth test 2012
A3 fifth test 2012
A4 second test 2012
A2 ninth test 2013
A5 second test 2013
A3 sixth test 2013
A4 third test 2014
A4 fourth test 2014
A5 third test 2015
A3 seventh test 2015
A4 fifth test 2015
A5 fourth test 2016
A4 sixth test 2017
A3 eighth test 2017
A5 fifth test 2018
A5 sixth test 2018
So when you basically whined about not testing A2 from 2004 to 2009, you have overlooked the fact that we tested A3 three times during this time frame. The improvements of A3 were later implemented in A2 even before 2010 and improvements of both implemented in A4 and improvements of all three are implemented in A5. And A2 was first time tested for 1500km range and it was later during 2004 when its range has been extended to 2500.
Because all your secret upgrades (most of them are original designs not upgrades) have been done before 2010, I really don’t see why you keep whinning about the so called new development?
The underlined part of yours didn't took into regard the fact that 2500 km range was not what intended for A2 at time of design. It was a development, not original design. And as per erstwhile Defence Minister of India, George Fernandez, A2 entered production into 2001-2002 and its induction was under way. It was not in 2004.
Regarding your knowledge of JV and development of sub component design of BRAHMOS, one noob question from me to a layman like you. When you use a fountain pen and have to use a different set of ink in it, do you think that the manufacturer of ink world around might have obtained the formula by industrial espionage rather then R&D? Because we could use ink by different manufacturer in the same pen without hampering its performance. But anyway I can't expect this much of knowledge from anyone who is world known for their copycat image.
