DARPA's ICARUS Program To Develop Self-Destructing Air Delivery Vehicles (darpa.mil)
Zothecula contributes this excerpt from Gizmag that illustrates the latest chapter in the long history of denying equipment of military technology to the makers' adversaries: Two years ago, DARPA started developing self-destructing electronics as a way to prevent advanced military gear falling into the wrong hands. Now the agency is expanding on the idea with its Inbound, Controlled, Air-Releasable, Unrecoverable Systems (ICARUS) program, which is tasked with developing small, unmanned, single-use, unpowered air vehicles that can can be dropped from an aircraft to deliver supplies to isolated locations in the event of disasters, then evaporate into thin air once their job is done.
Let's call the powered one "missiles" and the unpowered ones "bombs".
