Sailors take note: That fast-moving, gray and black object crisscrossing Puget Sound near Everett is not an orca, it’s a Piranha.
As in Piranha USV, a 54-foot-long prototype of an unmanned surface vessel (USV) that began its sea trials this past week.
It’s made of carbon-fiber composites like the 787 Dreamliner, but with an extra ingredient — nanotube molecules that add strength and stiffness, according to developer Zyvex Technologies of Ohio.
