CLEARANCE: Above Top Secret

There was always going to be a next generation engine after the F119/F135. I would hardly expect the DoD to do nothing in the engine dept. I also wouldn't ever have expected it to be significantly larger than the F135 as the preference seems to be "big enough for a single-engine fighter to use but not so big that two of them would be too big for a twin". And given the DoD doesn't seem to be crazy about F-20/Gripen sized aircraft that's going to set the lower limit on engine size. All that said, it seems logical it would end up in a size range that would fit in an F-35. (Though that LM notional 6th gen looks big enough to need a pair of NK-32s.LowObservable said:"Trying to kill" is overstated. However, recall that the Advent concept basically dates to the mid-1990s and was mostly constrained by funding (I am not aware of any critical enabling technologies that have been made possible in the meantime). Once the F-35 was planned as the only fighter until the 2020s, with an ATF-derived engine, the VCE had no sponsor.
The fact that many aircraft have gone through their lives with one engine type may reflect shorter production and service lives in the past. The 737 is on its third engine.
