Australia's ''future submarine'' could be a super U-boat built by a German company that made many of the submarines that nearly brought Britain to its knees in World War II.
HDW has released details of a concept design, designated the Type 216, for a long-range conventional submarine.
Experts say the design, based on the successful Type 214, is specifically targeted at Sea 1000 - Defence's future submarine program.
