Yes I am, sorry if I didn’t make that clear enough
tech level =/= construction numbers, China can have all the required technology but starting late they can theres only so much they could do about it. Also Chinese ships used AESA starting with 052Cs in the 2000s while the US did not field theirs still much later.
Chinese warship tech is no worse if not slightly ahead than the US, especially with domestic gas turbines entering service now. With aeroengines, once CJ-1KA enter serivce than China should catch up in comericial, WS-15 is already in LRIP since 2023, which is similar to F-135 in material if not slightly better in design due to newer. So approx ~10 years behind going by milestone dates, but China has been working concurrently on VCE engine since 2018 if I recall correctly so its possible by next gen engines this distance might shorten to 1-2 years if not shorter.
