A "disposable aircraft," the CICADA Mark III is comprised simply of a printed circuit board, which minimizes wiring and makes it fast and inexpensive to assemble. (CICADA stands for Close-In Covert Autonomous Disposable Aircraft.) Resembling a toy airplane, it can accommodate light payloads, such as chemical, biological, and other signals intelligence sensors. Other electronic payloads can be incorporated by updating the circuit board and "re-winging" the aircraft.
