Last summer, the U.S. military awarded Northrop Grumman a $517-million contract for a Long Endurance Multi-Intelligence Vehicle (LEMV). The 300-foot-long aircraft gets about 40 percent of its lift from its hull’s aerodynamic shape. It can stay aloft for three weeks at a time running surveillance. Northrop says the LEMV will be ready for action by the beginning of next year.
