How surprising... Developing a specific supersonic jet engine for this kind of plane would not be cost effective anyway, the fleet would be too small to worth the investment. Even starting from a military jet engine, the way they are run and maintained is very different from civilian jet engines.

On the maintenance side it's night and day, I used to work upstairs in the hanger building but not on the floor of a base with f-22's and before that f-16's and they rebuild those engines like clock-work there is always at least one being rebuilt if not a few.

Also good luck getting government approval for using a military engine derivate for commercial flight to Asia, or basically any country other than the origin of said engines. And even that will be difficult. Export control can be a bitch.
