Most likely by 2035 J-20A/S would be 500, same would be true for J-35. J-20 would be used for training only. If it turns to successful in operation and performance than 1000+ J-35A would be exported to other air forces. J-36, J-50 And their UAVs would be operationally active by 2035, hopefully.
If J-20A (with WS-15) started mass produced in 2026 for 50 units and increased gradually to 125-50 units in 3-4 years. In 2035 J-20A would be well over 500, likely 800 to 1,000.
Remember there are about 300-400 J-20 already in service, which is very advanced already, arguably the most advanced in the world after J-20A (some people may not agree and arguing with F-22 and F-35)
