Studies in regard of penetration show that for an equivalent weight in hyper velocity condition, some small penetrators with gap are more efficient in term of penetration than a penetrator alone. To demonstrate this theory in experimentation, the same test must be done at Mach 6.7 for the monolithic and the segmented projectile concepts. The segmented projectile is analysed for two different designs: the conceptual and the engineering. All the characteristics of the projectile in regard of components description, assembly weight and core weight must be the same. Experimental acceleration equipment and adequate instrumentation are necessary to control data and projectile behaviour in term of ballistic aspects. The launch of these two projectiles in the light gas gun needs the presence of a sabot. A sabot allows a projectile of a smaller calibre to be fired within a larger-bore accelerator. The sabot fills the bore of the gun during the firing stage. Usually, the sabot is a lightweight carrier. This means, the sabot’s effect on the core mass must be minimal during the impact with the target. This report will put some attention on the sabot resistance and on its capability to survive the loading conditions inside the light gas gun caused by the acceleration during the launch. This report will show the main results of the development for the sabot/projectile assembly. All the permitted dimensions and materials will be experimented to get a final sabot assembly that can resist t
