CIA’s Office of Advanced Technologies and Programs developed the Unmanned Underwater Vehicle (UUV) fish to study aquatic robot technology. The UUV fish contains a pressure hull, ballast system, and communications system in the body and a propulsion system in the tail. It is controlled by a wireless line-of-sight radio handset.

If that doesn’t impress you how about a covert “Seismic Intruder Detection Device” that looks like a turd.
