Aircraft program
Low-earth orbit, unmanned, reusable spacecraft used to demonstrate reusable space advancements, requires launch vehicle to exit atmosphere then can re-enter and land as a spaceplane (upon re-entry, vehicle is capable of Mach 25). DARPA involvement reflects potential military applications.
