In the early 90's GE developed the F-412 non after burning engine for the A-12. When the A-12 was cancel it sounds like the F-412 was cancel. It was base on the F-404 but with a bigger fan and it could produce 13,000 lb of trust. Why they did not keep this engine and turn it in to a afterbunering engine. If this was done it could produced around 25,000 lb of trust and could have been used in the F/A-18 E/F, instead of them low powered F-414. Also what was the fan size of this engine, I know it had to be between the F-404 and F-110 size.

B-2's and F-117's use non-augmented versions/deriatives of the F-404 and as far as the F414 goes, GE has already done the research and has already to go pending funding to offer an increased thrust version of the F414 for the Super Hornets. From what I have read on the program, the maintenance savings alone would pay for the upgrades over the service life of the engines.
After the USN royally f#cked the F-14 program you would think that the USN would have learned the lessons of history. From it's inception the F-14 due to budget cuts and program delays forced the SECNAV to cancel the USN involvement into the P&W F401 engines that it had been in with the USAF for the F-15, forcing the entire production run of F-14A's to have to live with the TF-30s which were only meant as an interim solution. I would like to think that USN will remember that ill-fated decision as one of the worst bean-counting decisions ever. More F-14 crew lost their lives due to the TF30 than in all the US fighter combat losses since the Vietnam War.
