Why is the thrust of F100-PW (IHI)-220 different?

There is a difference in engine power between the F-15C and the F-16ADF. Why is this? And the same problem is happening with F-15J(M) and F-16AJ

What @kitsune_qq said.
Specifically subsonic losses, as F-15 is designed to go 500+kph faster than F-16, which leads to more thrust losses below the speed of sound than F-16.

The slower an aircraft is designed to go the more thrust they have available in the subsonic range.

The answer is channel loss

But something else here is weird… Why is the F-16AJ equipped with the 220 engine?

It’s a 70s proposal that competed with the F-15J, it would’ve been put into service no later than the F-15J (1981) had it been accepted. The F100-PW-220 engine was only even introduced 5 years later in 1986.

F-16AJ should probably use the same F100-PW-200 as the Block 10.
