I am a C-5 Mechanic for the USAF, and we are being told that the engine program is on hold due to budgetary constaints. They need to do something fast, with a 70% launch reliability rate, and alot of that stems from engine related problems. I think that the
CF-6-80C2 will be the likely choice for it. Performance wise it will be like having a 5th engine on it. The TF-39 is getting real old, and we are doing alot of engine changes here lately.
At Pope, where not happy, until you're not happy!
