Juliet Marine’s “Ghost” Ship Emerges from Stealth Startup, Gears Up for War -- Xconomy
About an hour north of Boston, in a city by the sea, there’s a project underway to reinvent the marine industry. More specifically, the marine defense industry.
Imagine a boat that moves through the water differently from any other boat in existence. It uses “supercavitation”—the creation of a gaseous bubble layer around the hull to reduce friction underwater—to reach very high speeds at relatively low fuel cost. Its speed and shape means it can evade detection by sonar or ship radar. It can outrun torpedoes. Its fuel efficiency means it has greater range and can run longer missions than conventional boats and helicopters.
