Performance of Chrome-Plated 105mm M68 Gun Tubes with Discarding Sabot Ammunition

Abstract

This report describes testing to determine the feasibility of chrome plating the bore of 105mm M68 Gun Tubes to reduce wear conditions which affect performance of the M392A2 Armor Piercing Discarding Sabot (APDS) Projectile and similar rounds. Two chrome plated tubes were prepared and, with a standard tube for control, fired to monitor relative performance. Based on several factors, it is concluded that special characteristics and sensitivities of M392-type projectiles result in a tendency toward degraded performance in chrome plated tubes. Recommendations are made to defer use of chrome plating in the M68 until factors affecting performance are fully identified through an exploratory development program.
