What external contribution? India already makes sensors like Radars, RWR, SPJ etc, makes avionics, has good design team experienced by designing Tejas. Engine is the only part where India has not achieved much. But even that is within grasps with Kaveri engine certification. So, hardly any...

India has already completed preliminary design and it is in prototype stage. It is true that it is more convenient to have design in the beginning instead of starting from scratch. But with Indian design already in advanced stage, it will be inconvenient to change design as that will cause...

Why will India get USA design? India has to make new technology development according to base technology available. If India gets design from USA, then the requirement for different base technology will cause problems. The development process is not discrete event but is a combination of other...

The fuel is a special grade of kerosene, slightly different from ATF used in civilian planes. But the jets are capable of using ATF kerosene too with some reduction in engine life. So, the density of jet fuel is very similar to kerosene - 0.8kg per litre at 300K temperature

I wonder how you got the 6009 litre internal fuel tank capacity. Who gave you such accurate data to the last litre?

Space x does not have strategic usage. It is only economically efficient. If the country has enough resources to bother about reuse cost, then it doesn't matter. Russian economy didn't think. Russian just got rid of dollars and went into isolationist mode. It is just about foreign exchange...

People are intelligent by birth. Talent must come by birth. But, yes, on an average, it is not correct to say a country is intelligent over any other in most cases. What I intend to say is that Russian population is not crazy (like Islamic population) and are as intelligent and rational as...

Why so? Russia doesn't lack intelligent people and has no security threats of shortage or Resources. So, unlikely that Russia gets lowered in Technology. May be others like India and China will catch up but Russia will not fall behind What is starving funds? How will funds vanish? Funds are...

Yes, absolutely. India has vast Technology base in defence. India makes its own radars, satellite, rockets, missiles, older generation semiconductor (enough for defence), Al31F engine, communication equipment and has vast source codes from development for decades. Turkey has almost none of...

That is because Turkey has 0 infrastructure base. It can't even make a third generation plane. It can't make radars and imports the main components of its own radars but falsely brands it as Turkish radar. Turkey has no real basis for declaring TFX other than ambition. So, it is unviable...

AMCA has 5-6ton internal fuel. Even MWF will have 3.3 ton internal fuel and Rafale has 4.8 ton internal fuel. AMCA is much larger than MWF and even larger than Rafale

Even current 4th & 5th generation can control drone swarm. Drone wingman is a big thing. As that involves autonomous flight of the wingman and hence needs AI. But drone swarm is relatively simple

No, they are making many tools inhouse for 28nm and are developing the next generation ones too inhouse. Chinese import only some EUV for 45nm or older generation as that is allowed. But the 28nm and 22nm under development is made in China.

China is not allowed to get it from Western companies. China is making the tools inhouse and that is the reason for delays. China is being fully self sufficient and can afford it due to its large population of 1.4 billion (more than total population of NATO) and vast natural resource.

Wassenar group and few other grouping like australia group allows sale of high end technology for its member states only, not all states. So, Taiwan is allowed to get the tooling. Also, the dutch tools are having USA IPR but just manufactured in Netherlands. Netherlands has no extensive R&D for...

TSMC has much more than 25% USA IPs. Also, Wassenar and few other conventions ban selling of IPs of first 3 generations of chips. So, currentl, it is 14nm, 22nm and 28nm chips IP which are prevented from being sold to China. Yet, China has got 28nm and are making 22nm chips fab. This shows that...

There is a difference between innovation and invention. Innovation is just manipulation whereas invention is the real deal. Development of fab for newer geenration is invention. TSMC budget for R&D may be high but that does not mean that it can develop things on its own. China puts in much...

Can you tell me how TSMC gets its own fab IP for 14nm, 22nm etc? As far as I know, TSMC does not have an extensive R&D programme to develop fabs. TSMC was founded in 1987 when USA had already made 1um chipset. Starting from scratch and developing latest chipset appears to be too good to be true...

That is true. But, ToT to save time is also a valid option. If we can get technology, why waste extra time to research on it? It is better to catch up with others by copying and once caught up, do ingenious research and development

We should only buy technology. Manufacturing should be hundred percent Indian. Buying off the shelf is not at all meaningful. Only if there is a condition to do so for ToT, it is OK to buy off the shelf. Next, we need FGFA technology to fasten AMCA and it is beneficial to get it so that AMCA...
