To assist U.S. troops in Afghanistan, the United States Army has awarded a contract to Northrup Grumman to build its LEMV surveillance ship. This surveillance airship is longer than a football field. It can carry 2,500-pounds while hovering 20,000-feet above sea level at a whopping 34 mph(watch it in action!). LEMV will sustain altitudes of 20,000 feet for a three-week period and it will operate within national and international airspace. They are expected to go into use by the end of 2011. Three ships will be made, and the Army will pay 517 million dollars for this project.
