The battery-powered Voyeur weighs just four pounds, stands 27-inches high and is actually designed to be suicidal. It’s meant to hop out of sonobuoy tubes, patrol for threats for a while and then sink itself. Much more economical than helicopters or jets wasting fuel by attempting to ID surface targets (has the Navy’s gas bill gone up at the moment too?) Plus it looks waaay more creepily sci-fi. The company is located in the Purdue Research Park.”]
