The U.S. military considered the Airlander for surveillance and cargo transport. Global Hawks and Grey Eagles, America's go-to surveillance aircraft, can each fly for about 30 hours. Fully stocked, the Airlander could stay in the sky for five days with a human crew. In wars where small armed groups move over vast rural areas, such as in the recent conflict in Afghanistan, a long-range surveillance tool is very valuable. While America's military involvement in Afghanistan is drawing to a close, Hybrid Air Vehicles is billing the Airlander as a tool for humanitarian relief, communications relay, border patrol, search and rescue, and drug enforcement. In addition to surveillance, the Airlander can be set up to carry 55 tons of cargo.
