Speaking to reporters at the annual Air Force Association conference in National Harbor, MD, last week, the head of the Air Force Research Laboratory said both programs present their own technical challenges: The air vehicle for the TBG concept is a warhead design that separates from a booster rocket and glides to hypersonic speeds, up to Mach 10 or greater, whereas the scramjet-powered system would be slightly slower but more complex to build and operate.

It's a boost glide weapon. It's launched on a theater range ballistic missile, that gets it up to speed, then it separates from the missile and glides to the target at hypersonic speeds.
, less likely to be mistaken for a larger attack than a ballistic missile,
more flexibility than a ballistic missile,
more platforms to launch from, more just about everything than a ballistic missile.
