Purpose – The main purpose is to enhance the probability of Kinetic Energy Penetrators (KEP) hit and subsequent defeat of the hardened buried targets (Bunkers) by using modern techniques in missions to ensure precise neutralization of the high valued target in cost effective manner in all-weather capabilities. These bunkers are becoming high value targets to be neutralized. Design/Methodology/Approach - The modeling and simulation approach to validate the design and operational configuration and its warfare efficacy. The scenario is modeled using Matlab in minute details. The aerodynamic performance based upon rocket motor thrust data was achieved. The effectiveness was assessed using Bar’s criteria of perforation in concrete structures. After considering the effect of all the parameters, KEP is designed. Findings – It is observed that hitting of modified vehicle with a speed of 130 m/s will be able to perforate the specified target. For this purpose, selection of propulsion, drop height and wind/perturbation modeling etc. need to carefully chosen to achieve the success of campaign. Limitations – The centre of gravity is assumed to be fixed during entire flight. No roll motion is assumed. Results - The designed Criteria of penetration is successfully achieved to defeat the target by achievement of hit velocity (139.7 m/s), which is greater than critical velocity Vc (129.76 m/s). To attain the penetration, projectile drop at different heights has been performed on the same RCC plate emulating bunker. Conclusions were drawn iteratively that drop of the KEP from 500 m by using rocket motor of 200 Kgf / 2 sec thrust has resulted in optimal defeat of the target. Originality/value – The work is based addressing issue of defeat hardened targets using home developed KEP by adding unique reinforcements in design, which are aided by software simulation work.
