Keep in mind that CAC itself is undergoing large scale factory expansion that has only completed recently. The new facilities are likely to be more automated than ever before so it would need to hire more skilled labors needed to operate them.It's a shame that the J-20 production rate may be close to full capacity. Chengfei's turnover growth rate in 2023 has dropped from more than 20% per year for many years to 10%. This may be the reason why the Air Force received the J-35A. Chengfei can no longer meet the Air Force's production capacity requirements for the 4th generation aircraft.
