Do you even know how 1970s was? Was there radars like AESA, PESA back then?
Actually yes, active phased array technology did exist in 70s. Although it was very immature and mostly at the start of their development cycle to become what they are today. Much like in same position where India is right now. Although we are helped by advancements made by other countries which allowed us to leapfrog and take shortcuts.
For example we would be nowhere near what we are today if we never imported computers with Intel processors and relied only on Indian-origin equipment to compute our data.
Was there a high end plane like Tejas?
In the 70s, there existed many planes that can drop Tejas like a fly. In 70s, Lockheed was flying tech demonstrators for stealth aircraft like Have Blue. Where is our stealth fighter TD today?
What was there is 1970s at all? If you look at items like assault rifles then 1940s technology is still being used. There has been no major improvements.
Only if you know nothing about rifles and think that Sturmgewehr and AK-47 are still epitome of assault rifle technology. Ok by that logic there has no major breakthrough in flight since Wright Brothers - everything still uses lift to counteract gravity.
Have you compared? Do you have any background research?
You're asking me?
Yeah, got an example of 6x6 or 8x8 and became a hero! The 6x6 or 8x8 are not some great disruptive technology. These are low end technology which is not complicated. That does not require major research. For god's sake, civilian sector is not useful. The applications like computers, satellites etc all started as military use, not civilian. The question of money or profits does not come in strategic uses.. You seem to lack any understanding of economy and simply blabber.
If you pursue R&D for technologies with no regard for civilian sector uses, then you end up like Soviets did. That is basic rule.
Yes, tech is pioneered for strategic purposes - but almost all tech has dual use. If you don't tap into those dual uses, then you get no revenue. No revenue means you don't have the budget to research the next level of strategic tech.
In short - the civilian sector is what makes things economically viable.
The reason why India uses Israeli radars is because India did not invest in R&D earlier and India is catching on.
Exactly. Glad you finally realize that. But the catching up won't happen till next decade at the very least.
The BARAK-8 has been indigenised
Really? Where does the most important component (i.e. the seeker) coming from? Here's a hint: in the factory which makes seekers for Barak, they speak Hebrew.
and the radars will also be indigenised soon.
I'm sure you mean soon in Indian Stretched Time. Meaning after around 15 years.
India has developed Akash SAM on its own
You mean we managed to re-paint Russian Kub SAM on our own.
and has many other things like Tejas plane with FBW,
You talking about the same Tejas which is still unable to fire its 23mm cannon and god alone knows when will receive FOC? Please, Israel already did more than that with IAI Lavi prototypes.
All the ballistic missile techs India developed as part of Agni series are things which Israel had already had at least 10-15 years earlier as part of Jericho series.
Jericho-3 is pretty much superior to Agni-5. And J3 is already in service since last ~7-8 years. By the time A5 enters service there will again be 10+ years lead. And this is not even including the sheer technological superiority Arrow series has when it comes to BMD systems.
You mean the same ones the Russians pretty much walked us through building? If you really think Arihant class boat or the PWR powering it are the result of Indian R&D, you are way too naive to even have a conversation with.
which Israel does not have
...which Israel does not need is more like it. Where exactly should Israel patrol with an SSBN even if they did have one? In the Mediterranean Sea?
I am asking you about the reason behind the problem, not the problem itself. The problem of poor technology exists because someone did not allow it to be developed in the past and catching up has been a problem once the thrust was given by later governments, not because of magic. My question is who is that and what was the intention behind that. You are telling everything other than what is relevant.
Money is the reason.
If you think anything else was the reason why there exists a poor tech base, you are either stupid or an some kind of conspiracy theorist. I mean, ask yourself: who exactly are these idiotic external influence who is "not allowing" development of tactical tech like radars but have absolutely no strings to pull in terms of developing strategic, balance-changing technologies like ballistic missiles?
