Yep, and it's the same issue there -- if we had the $ to spend on re-engining the entire fleet, that money would be spent on getting new radars or new pods across the fleet first.

About 10 years ago I saw the actual list of prioritized, approved but un-funded upgrades for the F-15E. It was about 5 pages of single-spaced line items. New engines were not on the first page of that list.
