Dunno if any 4th or 5th gen fighters leave trails like that, certainly not an F117 or a B2. Some kind of drone or something experimental. Looks like the photo was taken during daylight hours, don’t think one would go too obvious with a spy plane.
Advanced aircraft leave contrails, as well. Contrail formation is based upon atmospherics. For a military operation one would get a contrail prediction from weather forecasters for the particular conditions of the day and then avoid those altitudes. You also confirm the contrail altitudes if you can.
Ah, but the modern brother of the ancient V-1 'Buzz Bomb' jet just might! A PDE (pulse detonation engine) fills the combustion chamber with fuel and oxidizer and then uses a detonation pressure wave to ignite it in a pulse of power. It supposedly can be used from subsonic to mach 5+ and is rumored to power the ?Aurora?
