The Ghost uses supercavitation and SWATH to slice through the waves.
rockets). Rocket exhausts could be vented into the water column through the struts, dramatically reducing the vessel's heat signature in combat, too.
Wave impacts are the easiest to overcome, thanks to the use of the previously mentioned SWATH technology. Because the main propulsion elements of the boat are submerged, the only parts of the vessel exposed to waves are its struts. Two main technological innovations help make the"Ghost" an impressive vessel by any standards, SWATH, and its drag reduction technology. Source:This uses the propellers to form a tunnel, or cylinder, of fast-moving air bubbles behind the propellers, and around the Ghosts' nacelles. In other words, Ghost could be described as traveling through a low-pressure tunnel of foam, rather than denser water, making it very fast indeed.
