Intended Readers This report is intended to be read by members of a research group who have an interest in physics and aeronautical engineering and wish to have a brief exploration of the development in RCS reduction technology 3. Executive Summary  RCS reductions are the primary method to reduce radar observability.  The main methods for RCS reductions are purpose shaping, absorption and trapping  RCS reductions are accompanied by limitations such as high costs and poor aerodynamic performance 2 / 6 4. Introduction Since radar was first invented to watch the sky, it has been a long history for the opponents trying to penetrate the warning system to deliver airstrike. Early attempts by the German were to cover the surface of the aircrafts with wo
