How many 4th generation fighter aircraft does the Chinese Air Force have?

As of my last update in October 2023, the Chinese Air Force operates a significant number of 4th generation fighter aircraft, primarily including models like the Chengdu J-10 and the Shenyang J-11. Estimates suggest that there are over 1,000 4th generation fighters in service. The exact number can vary due to ongoing production and modernization efforts, but China has made substantial investments in advancing its air combat capabilities.
