Here's an article about DARPA's recently announced hypersonics initiative to develop a a full scale Mach 20 demonstrator by 2016: DARPA Wants Hypersonic Rocket Plane by 2016 - Space.com.
I had thought this program involved scramjets but they apparently want a rocket powered carrier vehicle to release a glide aircraft (with optional rocket boost capability), which will fly at Mach 20 and test techniques for thermal protection, guidance and control, etc. The propulsion technology area is developing a single, integrated launch vehicle designed to precisely insert a hypersonic glide vehicle into its desired trajectory, rather than adapting a booster designed for space missions. The propulsion area also addresses integrated rocket propulsion technology onboard vehicles to enable a vehicle to give itself an in-flight rocket boost to extend its glide range.
