The SR-72 Darkstar, often called the “Son of Blackbird,” is an American hypersonic unmanned aerial vehicle (UAV) for surveillance, intelligence, and reconnaissance missions. Unlike current UAVs like the Northrop Grumman RQ-4 Global Hawk, which can take hours before arriving at station, hypersonic UAVs could be on station six times faster.
