The idea of Taiwanese next generation indigenous fighter in under 10 years is just moronic. Taiwan not only doesn't have the industry and tech to do it, nor the manpower and talents. Even Japan is finding it difficult to produce a stealth fighter. I think it would take Taiwan, Japan and South Korea's combined talent to develop one "indigenous" fighter.
You should be very careful not to underestimate either Korea or especially Japan.
Japan is perfectly capable of designing, developing, and building their own...and they are proceeding forward to do so.
Their biggest problem is cost.
But this has not stopped them from producing an excellent modern, enhanced aircraft in the F-2. It is arguably a new build, very advanced F-16 Block 52 with a better and larger wing, better radar and other sensors, as well as the improved F110-GE-129 engine..
They are just VERY expensive. They could buy three Block 52 F-16s for each one F-2. But that have ordered something like 130 F-2s in any case.
I expect they are looking to do the same type of thing with their own stealth fighter. They will get some F-35s for sure, but I expect they will augment them with their own 5th gen aircraft.
I believe Korea is capable of doing the same...albeit my confidence level is not as high with them.
Taiwan will not produce an advanced 5th generation aircraft on its own...but that does not man that they will not produce a very decent aircraft in any case.
But comparing their F-CK-1 aircraft, particularly the C/D version which is what they are upgrading to, to the JF-17 is simply not an apt comparison. The ROC is upgrading most of its A/B aircraft to the C/ version. That version is simply a very decent 4th generation aircraft with very much enhanced avionics, radar, electronics, and weapons capabilities over the initial aircraft. For Taiwan, which is basically a small nation, to have produced these is pretty amazing actually.
Now they are announcing that they want to develop their own future aircraft. As stated above, I expect they will end up doing something, and it will not be half bad when all is said and done.
Somehow disparaging that simply because it is Taiwan is pretty shortsighted in my opinion.
And this thread is not the place for that anyhow. This is not a place, and SD is not a place, where members throw poop bombs on other threads just because we have a low estimation of them.
Do they have the capabilities of a US...or China...or Japan? Of course not. but they are willing to step up and do what they can themselves...and in their situation, it is pretty much all they can do.
I respect them for it.
