According to Aviation Week, defense contractor Northrop Grumman has completed the critical design review for the blimp-like drone they’re building for the U.S. Army. The Long Endurance Multi-Intelligence Vehicle or LEMV, was designed to fly at an altitude of 20,000 feet for three weeks while toting surveillance equipment and an array of sensors. Assembly is set to start in February and by summer 2011 it will be operational and most likely tested in Afghanistan before the NYPD is allowed to buy a few of their own.
