US hopes to make 'flying submarine'
Updated on 24 October 2008
The US military is turning to the realms of science fiction in a bid to invent a flying submarine, authorities said.
Designs for a submersible aircraft are wanted by the agency which commissions advanced research for the US Department of Defence (DoD).
The new machine, dubbed a three billion dollar (£1.9 billion) flying submarine by US media, needs to be capable of carrying eight men and their equipment a combination of 1,150 miles by air, 115 miles by sea, or 22 miles underwater - in less than eight hours.
