As Lockheed Martin has found out with the both the F-22 and the F-35, fifth-generation fighters are hard to get right: the F-22 was recently grounded with a system problem that was causing pilots to black out, while the F-35 is behind schedule, over budget and testing the patience of the U.S. Air Force to the limits.
So, because a U.S. deskilled and groupthink-rich environment has such problems, those same problems will be there for the Chinese? Well, that is an environment that would have people shot for doing what the U.S. military-industrial-congressional-complex has done.
Also, I am curious how many communist factories let you drink your lunch under a tree in your pick-up truck?
And, the U.S. only has one fifth-generation fighter. The other that marketing pukes are trying to push as such is a complete disaster.
I suspect that Chinese problems will be somewhat different.
The key challenge facing Chinese designers is not in coming up with a stealthy platform, but the systems that go inside it. These include electro-optic sensors and an AESA fire-control radar – a generational jump in technology that comes as standard on F-35s and F-22s; stealthy coatings; and reliable engines. The latter are a particular bugbear for China, which has for years relied on Russian technology to power its fast jets. Many Western observers believe the Shen Fei is powered by two Russian-sourced Klimov RD-93 turbofans, reinforcing perceptions that this particular weakness is holding China back. The fact that the same images show that these engines appear to be ill-fitting suggests that Shenyang may be following the lead of Chengdu, which is believed to be trying out a number of different engines on the J-20.
The author needs to use a push mower on a warm summer day while wearing winter gear. Then maybe he will understand the concept of "thermal issues" with the F-35 and the show room options he claims work in an unproven and troubled weapons system that is way short of real operational testing.
As for the avionics, I would think the Chinese will not over reach like the U.S. has with the Just-So-Failed. They might use something like, oh, I don't know, a HUD, instead of a helmet/display fubar.
Engines? Yeah sure. And, we will see.
