Interesting to see these changes are if there are further changes as more aircraft continue to be produced!
As per the United States Air Force, Chinese weapons development programmes are up to 4x faster.
As per the Pentagon, the American aerospace industry can't handle a second 6th gen aircraft programme, without impacting the F-47 programme which was just awarded.
Then look at the difference between China and the USA in terms of STEM personnel, industrial depth and capacity, R&D output, etc

The only reasonable assumption is that China is ahead.
What if the flexible membrane on the nozzle flaps don’t tolerate heat very well and the defect is detected during test flight? They go for off the shelf solution before a better one can be developed.
If only it was easy to move the engines more outward and use the extra space for an extra long IWB or more fuel![]()
If impact on other characteristics is minimal the feature might make a return with some further development. Really depends on the reason for removal.YF-23's embedded exhaust is lined with heat resistant tiles, it would have been quite difficult to implement a thrust vectoring system based off that. If J-36 manages it it would be the world's first thrust vectoring embedded exhaust, just saying it is not at all a trivial task and we've all been taking it for granted.
It is quite likely the thermal load is more substantial than expected that they had to roll back to a less ambitious design. But damn, like you said it really looks like something took a bite out of its arse....weep
Is the second proto of J-36 use two engines than 3 engines?
What I really want to know is whether they've done anything to make that UGLY hump more visually palatable.
Next you’re going to tell us your significant other is a hunchback huh?Monkeys paw curls -- it is made more palatable by the addition of humps on the side (i.e. the side DSIs)
...
I kid, because the hump was always palatable and aesthetically pleasing to begin with.
