Scientists and engineers at UK defense and aerospace company BAE Systems believe that within this century they will be capable of growing Unmanned Air Vehicles (UAVs) using advanced chemistry and large chemical baths. The process would be capable of creating functional, near fully assembled drones for specific military operations within a matter of weeks. The process would require a cutting-edge chemical 3D printer and computer called a “Chemputer” that would grow the customized aircraft and some of their electronic systems at the molecular level.
