RB199 is in the same size class. Higher performance variants were mooted, maybe they would be developed.
Rafale might wind up using RB199 prior to M88 availability in place of the F404.
No F404 means no F412, so the A-12 program would have needed a different engine. Not that it mattered. No F412 also means no F414, so SuperHornets would need a different engine, but since the Hornet is also gone there wouldn't be Superhornets anyway, so yay, a path to Supertomcats.
Same for F404 upgrades for the A-4, and the A-6F.
The Gripen would likely be built with upgraded RB199 or EJ200 in mind.
On the other hand, the PW1120 might prove viable. A Gripen designed around it might be interesting, and non-afterburning versions might work for A-4s and the A-6F, assuming they fit. If they don't maybe Allison licenses RB199s.
