I think PAF will get a couple of J-35 for evaluation in 2026, with operational induction in 2027 insha Allah
Your timeline is overly optimistic. PAF's actual work efficiency may not reach that level.
General analysis:
SAC currently does have a small number of J-35A (WS-21 engine) fighter jets. These will be used for public evaluation by international customers of the FC-31/J-35 fighter jet. You can consider these J-35A (WS-21 engine) fighter jets as the top-of-the-line version of the FC-31/J-35 fighter jet.
After the general evaluation, international customers will resubmit customized requirements. For example, radar configuration, avionics configuration, cockpit systems, and even stealth solutions (China currently has three known and publicly available stealth solutions, corresponding to different purchase and maintenance costs).
Subsequently, SAC, CETC, AECC, and other relevant partners will submit price lists to CATIC. CATIC will then develop a contract draft incorporating a comprehensive package of services including weapon systems, logistics support, and pilot training, and engage in in-depth negotiations with the PAF. This process could be very lengthy. The core issues will likely involve multiple rounds of negotiations and discussions regarding payment terms. The involvement of a Chinese bank may also be sought.
The new pulsed production line for the J-35 series fighter jets, built by SAC, is expected to begin trial production in 2026. If everything goes smoothly, the production line could ramp up to near or full design capacity in 2027 or 2028.
==========================================================
Chinese official agencies typically do not release information about predictive, probabilistic, or intended matters. Therefore, they will only announce the arrival of the fighter jet when it is about to appear at a PAF (Pakistan Air Force) airbase.
We can infer the progress by observing changes at various PAF airbases. If a PAF airbase recently begins large-scale construction of new hangar facilities, it might mean that the "new toy" is about to arrive! (5th-generation fighter jets require dedicated hangars and related maintenance facilities.)
