WASP is the smallest UAV in use today, weighing less than 300 grams. The miniaturization is achieved by the use of multifunctional components, like the combined wing/battery. WASP is nearly silent and, when flown at night, it's almost undetectable. The Air Force has just ordered several hundred for reconnaissance and bomb-damage assessment.Photo: U.S. Navy
