Let's take a look of Chinese engines development timeline: The WS-10 engine started testing on J-11A from 2002; The engine only became mature enough (life time >300h) around 2010 and enter into massive production; Then after 10 more years usage, PLAAF was confident enough about the reliability...

Are these proving my point? Comparing to India, Israel has so much advantages in fund and purchase channels. Certainly they can plan their military purchase in a whole different level. And people always forget another key point: USA guaranteed Israel that her weapons will always be superior to...

Even as a Chinese, I have to defend Indian generals here. People like to check their performance against other countries military forces without considering the difference of resources they get. Israel spent 4.5% of GDP on their military forces, how much does India spend? Comparing to Israel's...

Very interested in to know your source about these 60 and 40 airports.

Chinese has been holding their industrial automation progress for quite a long time due to the massive new workforce joining the market each year until 2010s. I still remember that in early 2000s a friend of mine visited a US factory. He was shocked by the automation level of this factory, with...

No, because they made their sacrifice. There were plenty of countries willing to take the risk but very few countries were able to spend every dollar they have on it again and again. The key is: they successfully managed to keep their people living with minimum living standard for 30 years...

Because those friendly nations as you mentioned are all sourcing their key technologies from USA. And USA has a good reputation of undermining her allies' military industries.

That is interesting, we haven't seen the prototype of AMCA mk1, people start to claim the designing characteristics of AMCA mk2 are superior than F-35?

Jet's aerodynamic research is much more complicated than rocket. It not only covers different speed, but also different weather condition, different posture. In the past, you may only need a few wind tunnel to test rocket, but the number of wind tunnels required for jet is >20.

Those are only for civilian usage, precision is not good enough for high-end metal component.

Is he aware that F-22's maintenance is much worse than F-35? F-35 was never designed to be a air-superiority fighter. F-35 is probably the most balanced machine on the earth. When we are talking about balance, we can't just judge it between stealth and aerodynamic, we also have to consider...

Did this Doctor say that? On this planet, there is no one has more experiences and knowledge on aerodynamics and stealth design than Americans. Let's see what kind of design that Indian scientists can come up eventually.

How can you do the RCS test on individual parts?

But processing diamond to build the blade is completely different thing: Are you going to "melt" them to a new material or just attach them to the surface of the blade? No matter what you do, you are going to see the new problems. Devil is in the detail.

That is not 100% true. There was no term in the F-35 deal regarding the AESA knowhow. The TOT of AESA was talked about in the deal of KF-21.

No, this kind of off-shelf product is downgraded version. Its capabilities of data processing, multiple tasks, etc, are limited. Most of them are only suitable for civilian usage. For those imported for military jets, it depends on the particular contract, in other words, the will of the sellers.

Is that AMCA? or Korean KF-21?

Only if you find big faults in the original design. Most of the modifications after first test flight are minor and doesn't change the major characteristics of the design.

That is because you only see the prototype. The major changes happen before. The original external design is only based on the theory, unfortunately human's understanding about aerodynamic/stealth is still limited, most of time is based on experience not scientific systematic theory. So, in most...

It is not about who is more efficient, but who gets what! When you bring the private companies getting into the military industrial, the condition is that these private firms must have the knowledge, technician team, equipment and infrastructures to do the job. The tech standard of these in...
