I've seen a couple references online and it seems to suggest the Aurora project has discontinued. The Galleta is the supersonic heir-apparent, a
smaller aircraft that can achieve mach 6 speed. I've never heard of it previously and suspect it might be a hoax - any thoughts? Thanks for your
help!
Looks like just another fancy name for the supposed "Aurora" or next generation SR-71.
I would suggest reading up on RBCC and TBCC propulsion methods. Also, I would direct you to the
SR-72 Confirmed: Mach 6 Project Blackswift thread since the "Galleta" and
SR-72 are probably just the same plane.
