Hovercraft having stealth function

A hovercraft having a stealth function comprising:

• a hull in which a cabin is provided;
• a power generator provided on the hull and configured to supply a lifting force with which the hull is lifted and a propelling force with which the hull is propelled;
• a skirt provided at a lower portion of the hull and causes the hull to be lifted by the lifting force supplied by the power generator;
• an opening/closing louver assembly comprising a plurality of opening/closing louvers on air intakes formed in an outer surface of the hull;
• and
• a steering louver assembly comprising a plurality of rudder louvers that are rotated and opened/closed on a port and a starboard of a rear of the opening/closing louver assembly on the outer surface of the hull,
• wherein each louver of the plurality of opening/closing louvers has a rectangular cross section having a longitudinal axis inclined with respect to an axis perpendicular to an upper surface of the skirt, and/or each louver of the plurality of rudder louvers has a rectangular cross section having a longitudinal axis inclined with respect to the axis perpendicular to the upper surface of the skirt, and
• wherein the plurality of opening/closing louvers or the plurality of rudder louvers are positioned as being mutually symmetric left and right, and configured to scatter incident energy of radar electromagnetic waves along with the outer surface of the hull, and to have a shape of an irregular surface.
