F-35 adopts some technologies from F-22, which saves a lot of technology development costs. Moreover, the F-35 is jointly developed by many countries, not by the United States itself. The F-35 is designed considering the needs outside the United States, while the F-22 is designed for the US Air Force, and the output gap will be very large.
The initial production price of F-22 is $654.38+0 billion, and the price of F-35 is estimated to be around $35 million, which will not fluctuate greatly.
The radar of F-35 is more advanced than that of F-22.
Maybe other technologies and products are mature.
In addition, the maximum takeoff weight of the F-35 is about 27 tons.
F-22 exceeds 32 tons.
