The Aerocon Dash 1.6 wingship, a 5,000-ton ground effect vehicle concept

The Aerocon Dash-1.6 wingship was a proposed ground effect fixed wing aircraft. As part of a five-million dollar congressional grant,[1] the aircraft was studied by the Defense Advanced Research Projects Agency (DARPA) in the 1990s to recommend to the United States Secretary of Defense whether to spend billions of dollars to develop a wingship program for military uses.[2] The aircraft could also transport a combination of 1,500 short tons (1,400 t; 3,000,000 lb; 1,400,000 kg) of cargo and 2,000 passengers a distance of 11,500 miles (18,500 km; 10,000 nmi) at speeds close to commercial airliner levels.[3] By the end of 1994, the Department of Defense decided that constructing wingships of this size was too risky compared to their advantages.[4]
