The Navy has identified the need for a system capable of simultaneously breaching obstacles and clearing mines, in-stride, from over the horizon, during an amphibious assault. In response to the obstacle-breaching concern, the Enhanced Bomb Effects for Obstacle Clearance program was started. The purpose of the NSWCDD/CSS Bomb Effects program is to study and identify the damage mechanisms of obstacles (on land and in water) subjected to multiple bomb detonations. This acquired knowledge will then provide the acquisition community with the information necessary to utilize the proper technology for development of an obstacle clearance system.
