First of all, the Aurora may not exist, and in my mind it probably doesn't.
Typically a plane may be fully top secret, as in its very existence denied, when the military do not want their potential enemies to even start
guessing as to what they need to defend against.
In other cases the actual aircraft may be made public, but its operational capabilities may be kept secret when its possible to do this - in some
cases just looking at an aircraft is enough to give you a head start on the technology implemented.
For example, the B-2 Spirit was made public from the start, it was even rolled out at a public event. Its capabilities and technology was kept
secret, but its photo was plastered all over the press.
The F-117 on the other hand was kept secret for quite a while, and when it was made public only a blurry photo was put into the public domain.
The differences between these two are extreme, and thats because the very look of the F-117 told the entire story - angled panels in such and such a
fashion meant stealth. The B-2 was much more subtle, and its technological advances were in other directions, that weren't apparent in any photo
shoot.
The F-22 and F-35 are being developed fully in the publics view, and that is because stealth is expected these days, and they are both going to be
main stream aircraft.
The X-45C doesn't employ any radical new technology in the airframe, its all behind the scenes - theres nothing to be gained in keeping the aircraft
visually secret (and yes, keeping an aircraft 'eyes sensative' costs a *lot* as it restricts what you can do, where you can do it and when you can
do it).
Hope that helps.
