IAI provides sneak preview of long-range maritime drone

It can fly 1,000 kilometers and stay in the air for 20 hours without refueling, hover at 9,144 meters (30,000 feet) and provide high-definition radar and visual images of targets spanning hundreds of kilometers.
These are the capabilities of Israel Aerospace Industries’ Maritime Heron drone, a hitech pilotless aircraft that is already in service in the Israel Air Force, the Israel Navy and the armed forces of several other countries.
