Military Transformers: 20 Innovative Defense Technologies
May 15, 2012 11:00 AM Department of Defense technologies under development, from brainy microchips to battlefield transformer vehicles, promise to make the U.S. military more nimble. Here's a visual tour of 20 breakthrough ideas.
DARPA's Nano Air Vehicle (NAV) program aims to develop a miniscule "air vehicle system" that's less than 15 centimeters long and weighs less than 20 grams. One experimental design incorporates flapping wings, disguised here as a hummingbird, making it possible for the device to navigate both indoors and outdoors. DARPA expects the NAVs to push the limits of aerodynamics and maneuverability.
