 SilentEyes looked like a simple metal cylinder with a rounded cap, straight folding wings mounted in the middle of the UAV and with a noticeable dihedral, and a folding inverted-vee tail.The UAV was 46 centimeters (18 inches) long and less than 7 centimeters (2.75 inches) in diameter.Raytheon called SilentEyes a "parasite" UAV, as it would be dispensed from a larger UAV such as a Predator; a gliding submunitions dispenser; or a cruise missile.
