Hypersonic flight refers to the motion of aircraft, missiles, or spacecraft through the atmosphere below the Karman line at speeds greater than Mach 5, above which thermochemical effects and aerodynam

…renamed to the Experimental Spaceplane Program), with the intent to increase national security by inventing a new, inexpensive, short-notice form of hypersonic aircraft. They promoted concepts such as reaching a Low Earth orbit within days, unmanned reusable rockets, external boosters being replaced by internal…

Velocity-altitude diagram showing different flight regimes: 1) endo-atmospheric and trans-atmospheric flight (including subsonic, supersonic and hypersonic flight); 2) exo-atmospheric flight at suborbital velocities; 3) orbital flight around Earth (circular, elliptic, and parabolic orbits); 4) interplanetary flight (hyperbolic orbits); 5) interstellar flight (highly hyperbolic orbits); and 6) unmanned interstellar flight (too high accelerations).

Hypersonic weapon, demonstrating its non-parabolic trajectory (denoted in red), has a distinctive signature which is being tracked by one of the layers of the National Defense Space Architecture (§ NDSA) beginning in 2021. Tranche 0 is to begin deployment in 2022. The satellites of the NDSA, in gray, are to be deployed in constellations orbiting Earth, and constantly keep Earth in their view, depicted by the blue cones representing the fields of view of the satellite constellations. The satellites are to intercommunicate and serve the defensive systems arrayed against enemy hypersonic vehicles, and build a
