World's first pilotless supersonic combat drone on sale for $16m

"The main driver for supersonic unmanned combat aerial vehicles (UCAVs) is to allow them to operate alongside piloted, supersonic fast jets in tactical situations without having to coordinate between aircraft types with very different levels of performance," said Justin Bronk, research fellow for airpower and technology at the Royal United Services Institute (RUSI). "In other words, UCAVs designed for 'loyal wingman' type operations are more likely to be designed with supersonic performance than ones designed to operate independently."
