Great Horned Owl program-
Super Silent drones (2012(-
"Iarpa has reportedly awarded a $4.8 million contract to Connecticut firm D-Star Engineering to develop the ultra-quiet drone, Aviation Week reports. It's the next step in developing a workable drone as part of the agency's Great Horned Owl Program, which the agency hopes will let the military collect intelligence "without anyone knowing you are there," (.pdf) according to an agency briefing.
Sound, after all, is the number one signature "that gives away the location of low-altitude UAVs and gives away their presence." Which sort of defeats the point of having a secret surveillance eye in the sky. In some cases, you might want people to know you're watching. At other times, you want to sneak up quietly."
