"At the front of each foil is a special propeller system that pulls the craft forward. The propellers are powered by a modified gas turbine?a jet engine?housed in each foil; the air intake and exhaust ports for the engines are in the struts. As the ship moves through the water, the motion of the propellers creates a thin layer of bubbly water vapor that surrounds each foil from front to back, helped along by the presence of ?air trap fins? that keep the vapor in contact with the hull (and keep liquid away from the hull). The vapor is what constitutes the supercavitation, so the foils can glide effortlessly through the bubbles."
