2. The J-35A also serves as an aggressor aircraft, simulating the large numbers of F-35 in China's vicinity during BVR and close-range air combat training.
3. The J-35A's internal fuel capacity exceeds 8 tons, giving it a range no weaker than that of older Flanker variants
And people are still saying "The PLAAF doesn't need the J-35A! Only J-20 is enough!" in this forum.
Aggressor aircraft squadron purpose aside - That means the PLAAF will be
fielding mid/lo-end 5th-gen fighters that are
Flanker-ranged (which is about 1250-1500 kilometers of combat radius). And given the comparably cheaper price tags to the carrier-based J-35, let alone the J-20/A/S - Having a sizeable fleet of J-35As in service with the PLAAF means that China will
further solidify and expand upon her advantage and control of the skies within ~1000-1250 kilometers of her coastlines and borders - Whilst leaving the J-20/A to conduct missions beyond the 1IC and/or other battle areas of greater significance/importance.
Wanna know what 1000 kilometers out from the Chinese coastlines and borders look like? Here's how it looks like:
~1250+ kilometers of combat radius, let alone with mid-air refueling support is only going to push those circles' borders farther outward. So there's that.
