The Ben Franklin mesoscaphe, also known as the Grumman/Piccard PX-15, is a crewed underwater submersible, built in 1968. It was the brainchild of explorer and inventor Jacques Piccard. The research vessel was designed to house a six-man crew for up to 30 days of oceanographic study in the depths of the Gulf Stream.
