The Joint Committee, along with Armed Services Committee were two of the Electric Drive Submarine's supporters, and with their urging, Navy budget inclusion saw plans for development in 1970. This electric drive submarine, though mentioned in the public Reports from 89th Congress, was highly classified and indicated the US Navy concerns for advancing beyond just nuclear powered submarine technology and propulsion. There were at least a couple of reasons. One of these involved the undersea noise factors from operating nuclear propulsion. Electric Drive offered a quiter and less dectectable submarine and it was one of the early indications for environmental history in technology and its effects upon the ocean environment covering 70% of the Earth.
A cleaner technology had its own advantages and historically would move forward beyond the limitations found in nuclear propulsion, even though 1968 marked a watershed year for developing nuclear power in aircraft carriers and the US Navy transition to nuclear powered surface ships.
Had a once in lifetime opportunity to see the EDS, from a distance, while it was being developed. The submarine reminded very much of Jules Verne and his classic Capt. Nemo submarine from his literary fiction. It was only a moment in time but portended the future of Navy history.
