A question was asked in the OMEGA accident thread abuot 707's being re-engined with JT8D-219 engines. Doing some research I found that the USAF is going to put the -219 engine on their E-8's instead of the CFM engine like the KC-135 and so on. Any guesses as to why?

It sounds like a shockingly sensible idea. A 19% savings in fuel burn, probably millions more per plane saved in retrofitting each plane, a huge performance increase, works better with their sensor arrays, way cheaper per engine...and only 6% less fuel efficient than the -56.
Makes so much sense I'm surprised they are actually doing it.
