Since the installation of upgraded engines on the F-14, F-15E, F-16 and Legacy Hornets in the late 80's/early 90's, both the Navy and AF have refused to purchase improved engines for their aircraft despite their availability from GE and Pratt and this in the face constant weight gain and higher drag on all fighter aircraft..
744SPX wrote:Yes, they all did get newer engines fitted, but my point was it was 30 years ago and all these aircraft have continued to gain weight while thrust upgrades have been available for a very long time. The US F-15E and F-16 fleet could have been fitted with 32-34k versions of the F100/F110 20 years ago. The Super Hornet has received no thrust upgrades despite the fact that it needs it more than the C/D ever did. The F-15C never got a thrust upgrade.
744SPX wrote:I get what you are saying about cost benefit, I'm just always of the mind that you can't have too much thrust. Also, considering how much DOD money is uselessly thrown away, I think thrust upgrades are more than justifiable.
744SPX wrote:Also, I'm pretty sure both the F100 and F110 32k versions have proportionately increased dry thrust, between 19,000 and 20,000 lbs I believe. Both engines have higher airflow fans so its not just about afterburner thrust. Also, the F100-232/229-EPE use F-119 tech not just for more power but also more fuel efficiency.
