When you look at what the F3 could do with only 16,000 ish thrust, it does very well.
Having spent some time rebuilding them and speaking to Rolls Royce, it would have been very easy to upgrade that to 18,000 at least. We did not buy that.
We bought more time on wing.
A better LP comp would have boosted dry power like the German MK 105 motors.
