To be able to assess the penetration capability of long rod projectiles (LRP) in modern armours, it is necessary to know how yawed and/or deformed/fragmented projectiles interact with subsequent components in the armour design. In this report, a survey of the open litterature on yawed and deformed LRP penetration capability in homogeneous targets and oblique plates is made. Rather few early such studies are reported, but the number has increased in the last 10-year period. Most of the studies are on yawed, undeformed LRP penetration in perpendicular, homogeneous targets. These studies show that for modern, large aspect ratio, LRP even yaw angles of a few degrees are strongly detrimental to the penetration capability of the projectile. Larger yaw angles, of the order of ten degrees, can more than half the penetration capability and side-on attitudes give only a fraction of the inherent penetration. Only few studies are reported on the penetration capability in oblique plate targets, which is an important application. No systematic studies are as yet reported on the penetration capability of deformed LRP.
