I see the general angst in people about defense development. What many people fail to understand is that defense development is NOT a linear process. That is, if it took 20 years to develop the first prototype, it does not mean it will take 40 years to develop the next 2 prototypes. Once a design ecosystem is set and talent is created, future prototypes are going to get released at a much rapid pace. Engine development is quite similar. Once materials science capabilities and test platforms are created, the simulation and development of prototypes is much faster. What is holding our engine development back is a general lack of use of advanced materials in other sectors of the economy. But by slowly indigenizing materials such as managing steel for ships, crystals for lasers, optical lenses for sensors etc., we would get into a position where making a single crystal blade should happen naturally. For instance, we miniaturized nuke reactors for SSBNs and developed cryogenic engines because we had other ecosystems present that made these achievements feasible. A combination of ecosystems is what led to advanced breakthroughs in the west. Not like yeah I am going to go target a single crystal blade development from day one. It will all come. Robust ecosystems development is what is needed. A sophisticated and advanced quality MIC is what will really deter the enemies. And we are building toward that.
Who would have ever thought that India would be making power plays exporting supersonic missiles? Yet we did. The same will happen in jet engine development. Why? Other ecosystems like a large domestic airline industry with MROs setup in India, will gain us certain advantages that small countries like Turkey will not be able to get. And that is the difference. People underestimate this advantage of being a large ecosystem.

I am somewhat OK with the development and procurement pace of Indian Armed Forces. Previously, we used to crawl then we learnt how to walk and now we are walking. Eventually, we will also learn how to run and sprint.

The biggest problem we face is we are unable to produce world class engineering talent at scale. This is because we lose all our world class talent to other countries. Until this is stopped and reversed, our pace will be slow. Right now the overall engineering talent in the country is not top grade. Some private companies have managed to retain talent but talent could leave any day. We have never focused on producing quality engineering talent that actually builds and makes things including futuristic technology.
Would top Indian students who get educated at MIT return to India to develop products here? Nopes, but an MIT educated Chinese does return to China. That is the major difference. Unless we solve this issue, we never ever would be able to compete with top engineering countries.
‘And we have only begun to solve this issue slowly in this decade. But still the output from IIT students and professors is subpar compared to their overseas counterparts. Not only have these people not founded great product companies in India, they continue to focus on careers in services.
We simply have not been able to create top engineering education and manufacturing ecosystems. Nothing even remotely close to the Chinese ecosystem. For example, entire industries like robotics, advanced CNC machines, precision machine tools etc are totally absent in India. Without building up this entire ecosystem we cannot produce engineering output quickly and with quality. The PLI scheme is a start. Let’s see if it sparks the fire of engineering and moves people away from services to develop advanced manufacturing products. But this is just a hope for now. I don’t see fundamental changes on the ground.

Did India signed deal for such systemd
Ghost of Karachi strikes again .
On topic
@binayak95 i always wondered why our some missile seems to be a lot slower than their counterparts while others have good acceleration ,like ad 1 seems a bit slower but the emission flame is large which proves a high thrust , so what to assume ?? Do we tamper with the videos released to not show actual speed and performance of strategic systems ??? Similar for k4 , it's acceleration is quite good but if we talk of ground based A5 , its initial acceleration in video was lower , what could be a possible explanation??

Difference in first and second stage of the missiles. Others prefer to have a short burning fast accelerating first stage, we prefer slow burning and longer lasting first stages (and consequently, a faster burning second stage) - ergo, we prefer our missile to have near max KE in its terminal stage.

Wouldn't the short burning fast accelerating first stage missile have higher KE at second stage ignition?

What about net reaction time ?? Won't it be affected by slow burn rate ??also what does k4looks like ,never saw a image in open source

Detection of a missile happens based on its altitude, not speed. So whether you are moving slow or fast, after a certain altitude you would get detected by GBR.

Reaction time for a ABM shield is same for any missile irrespective of its speed.

The newest S4 Indian Nuclear Submarine which I believe soon will leave the dry dock; could somebody educate us as to what is power of the nuclear reactor in it? The Arihant has a 85MW reactor. Is the Arighat powered by the same reactor?

What about the higher power reactor needed for future planned nuclear submarines and attack submarines which probably require double the power to operate. Are these new nuclear reactors are ready and operating?

As per Federation of American Scientist.

(45)It has also been reported that the Russian submarine-design bureau Rubin is cooperating in developing the nuclear submarine's 190 MW PWR.
