Well, considering China is a country that made mass transit work via high-speed trains...
Not sure why that's relevant.
Its not like China invented the concept of mass transit or high speed trains. They have built a successful network, but that has as more to do with its population density and command economy than it does its technological abilities.
...has an impressive space program...
Some of the technology in the Chinese space program was purchased from Russia.
...I'd say they are perfectly capable of resolving any problems they have with their engines.
Then why haven't they?
They've been working on engines for years, and they haven't even got the bugs worked out of their
previous engine design, let alone the one for the J20. They've also had the advantage of borrowed/stolen technology from Russia and the US, and they
still haven't perfected them.
They are the most populous country with the largest economy on earth....so I am not so quick to dismiss their efforts.
Their population size does give them certain advantages, but they seem to be lagging its major competitors when it comes to military technology.
I don't think the J-20 needs to match the F-22 one-on-one. It needs to keep the F-22 busy enough so that the J-11s can move in...
That's a rather silly argument.
With all of the technology that the U.S. has in their planes, do you really think that the F22s will be so distracted by J20s that the J11s will 'sneak in' some how?
A more likely scenario is that the F22 will be busy with the J20s, the J11s will pop up on the radar screens, the F22s will fire off a couple of missles and wipe them out, then it will go back to take care of the J20s.
he F-16s don't have the fuel capacity to fight such a fight in the wide-open expansesof the western pacific.
Which is going to become irrelevant because the F16 will be replaced with the F35... (a plane that, thanks to its single engine design and internal weapons bays that reduces drag)... and the F35 will have a pretty good combat radius.
The F-35 is a dog. Anyone can shoot it down at close range.
Actually no, its not.
The myth that the F35 "can't dogfight" is just that.. a myth. It is based on an article from a blog called "war is boring" that looked at a report during a test flight matching an F35 and F16. The problem is, that test was never a comparison of the 2 plane's combat capabilities... (For example, the F35 did not have all of its software/avionics functioning.) Instead, it was a test of the F35s flight control systems, which allowed engineers to adjust its systems to improve performance.
Other more relevant "dogfighting" scenarios have shown the F35 can hold its own in the unlikely event of close-up combat.
