Sorry, what is ATEP, VCE and what engine are you talking about? LOL

WS-15 just need to be better than WS-10C and more reliable than F-135 to be a very good engine. Will be a great step in the right direction.

ATEP is the tech development program for the US’s next generation fighter engine. The specific engine candidates for the program are the XA100 and XA101. VCE=Variable Cycle Engine.
Not sure about thrust but F35 optimized for strike so F135 has higher bypass than F119, conferring greater efficiency/range at the cost of lower top speed and supercruise. WS-15 goes for the F119 approach, emphasizing speed over efficiency.
i think gap is not that large. but i m not the right person to answer this question.
@latenlazy can you please answer.

So can I interpret this to mean that to the best of your knowledge, despite the 20 year gap, there are no (or very few) technological milestones separating the F-119/F-136 (without consideration the the vertical lift ability) and the ATEP? And also, by that logic, between the WS-15 and the ATEP? Thanks
To expand on this since it's a current topic, variable cycle engines allow you to have the best of both worlds. The engine can vary its bypass ratio in flight, so it can optimize for speed or endurance as the mission requires.
Indeed, so range is gonna take a hit for the J-20 with WS-15. Don’t know how it compares with WS-10C variant.
No. There are definitely going to be some big milestones between ATEP and F119/F135. Three stream variable cycle is a good leap in technological capability. And they’ll be pushing the frontiers on materials. But the ATEP is also still in development. It’s probably not going to finish development for another few years.
WS-15 should have compare with F-119 and F-135
ATEP is the program for next generation engine. in which Variable cycle engines have participated.
for ATEP comparison we should wait for China's next generation engine. currently under development.
