Analysis of 155mm M483A1 Projectile Accuracy Based on 155mm M107 projectile Registrations

Abstract : Current Field Artillery doctrine requires that each family of projectiles, such as the 155mm M483A1 and 155mm M107 projectile families have its own registration. This requirement dictates the firing of many projectiles which is not only expensive, but it also takes time and, in combat, probably reduces the chances of survivability. By being able to conduct a registration with one type of projectile and having the firing data applicable to all projectiles of the same caliber, regardless of shape and ballistic similarity, these problems would be minimized. This report presents an analysis of a series of test firings, which was conducted at Ft. Sill, OK during the Fall of 1977, to ascertain the ability of the 155mm M107 projectile to be used as a registration (spotter) round for the 155mm M483A1 projectile.
