In other words, 117S is not a F-119's equivalent, reinforcing my point that China has no need for 117S. Since China has no need for the most valuable thing on Su-35, the Su-35 is worthless to China.
As for 117, it is not for sale and is not used on Su-35. Even if it is, China still does not need 117 as China has WS-15 which will be ready around the same time.
LMAO. You "do not know" does not have any relation to WS-10A's status whatsoever. WS-10A is in serial production and that is a fact.
As for AL-31F, the primary reason China still buys it is to equip existing aircraft that are not designed to take on WS-10A. New engine type requires redesign of the inlet, which in turn leads to structural modification of the aircraft. For example, J-11B's inlet is slightly bigger than standard Su-27 inlet to match the flow rate of WS-10A. That is why only newly designed aircraft such as J-10B, J-11B, J-15 and J-16 are equip with WS-10A.
