Development of increasingly sophisticated Radar detection systems threatens to reduce the mission effectiveness of many type of modern weapons platforms (such as Surface-Effect-Ship (SES)). Strong attention is now being given to methods of increasing Survivability by reducing detectability with Radar Cross-Section Reduction (RCSR). Surface-Effect-Ship (SES) is a Fast ship that Operate in the near shore, so that with considering the probability of tracking this ship in short operational range from shore, the RCSR of this ship became a great vital task. In this paper the method of RCSR of this kind of marine vehicles with "shaping method" is studied. First A certain SES vehicle is analyzed and the maximizing points in RCS plot is determined. Then by shaping technique, the hulls and superstructure and nose of this SES is modified to reduce the magnitude of these maximizing points. The reduction in RCS by this method is seen to be at least 1.0089 dBsm at φ = ۹۰۰ and 19.9307 dBsm at φ = ۲۷۰۰ which are approximately 20% and 98% in RCS reduction respectively.
