Objective: The main objective of this article is to present the results of the radar cross section (RCS) reduction measurements of radar absorbing materials (RAMs) carried out by the insertion loss method in a semianechoic laboratory environment, in the X band (of 8.2 at 12.4 GHz) and subsidize the continuity of the activity by carrying out the operational assessment of these items in an operational environment. The laboratory tests carried out aim to seek subsidies to refute or confirm the following hypothesis: The MARE constructed contribute to the reduction of the RCS of naval means constituted by metallic structures. Method: The method employed allowed obtaining reflected power values of up to –42dBm for the measured samples. Results: The results obtained were considered satisfactory. Conclusion: The results obtained allow concluding the validity of the hypothesis that all manufactured MARES contribute to the reduction of the STR of naval assets made up of metallic structures in the X band.
