The New Hampshire based Juliet Marine Systems, Inc. has been working with the U.S. Government on the formerly ultra-secret GHOST, the world’s first “super-cavitating” craft, which essentially means that the boat/submarine has the capability to “fly” through an underwater gaseous environment that enables the craft to travel with 900 times less hull friction than water. The idea behind this technology is pure stealth. In super-cavitation, water pressure is consistently lowered below vapor pressure, allowing the specially-shaped nose of the craft to deflect the mass of water around the body at high speeds, thereby creating low pressure and a resulting “cavitation bubble” that travels around the craft and closes behind it.
