"The submarine of the future may differ greatly in aspect and function from today's system. As he looks to the 21st century challenges, Admiral Frank 'Skip' Bowman sees "five key areas of innovation which we'll need to work on in order for submarines to continue ti evolve and maintain the capabilities needed to carry out the broad and significant roles we are being called to perform. In simple terms, we need to do more to get connected, get payload, get modular, get electric and mean-while remain affordable."
