re: Falcon Blackswift?
The names are given by people who are guessing about the black project, not by guys running the project- for them this thing doesn't officially exist or it is hidden as another project:
From article:
"According to the few details available on Blackswift, Lockheed Martin’s famed Skunk Works shop is the main contractor for the vehicle. DARPA, in fact, still isn’t talking about Blackswift; it’s using the HTV-3X designation. But HTV-3X is a departure from the previous Falcon program."
