Because they share the same airframe components. Boeing builds the F/A-18E/F Super Hornets on the same assembly line.

Re: JH-7/JH-7A Thread
wonder why xian do not adapt RD-93 ,instead choose to adapt weight saving composite material.
during the first public flight demonstration in 1999's zhuhai airshow,a lot of western reporter and military attache claim the aircraft was under power.this is open admission by Xian aircraft.

Re: JH-7/JH-7A Thread
Changing the engine would require a massive redesign to the plane, while using composite material is minor modification. So it's quite obvious why Xian choose weight saving instead of power increase.
The rumor of WS-6 in JH-7 is completely BS. Since WS-6 was discontinued in the early 80's, and the dimension is completely different from WS-9.

RD-33 makes even less power than the WS-9 although it has a much lighter weight. On the other hand, that lighter weight on the rear is going throw off the plane's balance. To restore that balance, you wil lbe forced to add weight in the rear as ballast, which will negate the RD-33's superior thrust to weight ratio. You will end up with the same weighty plane with even less powerful engines. Weight reductions on a plane has to be properly distributed or allocated, not concentrated on a single area in order to retain the plane's weight distribution.
