Description

The projectile consists of a hollow steel forging with a boat tailed base and a streamlined ogive, and may be either the normal fuze cavity or deep cavity type. It is loaded with 2.15 pounds of Comp B (1.68 pounds, deep cavity) or 2.15 pounds of TNT (1.6 pounds, deep cavity). Some earlier rounds are loaded with 50-50 amatol and a booster surround of a small amount of TNT. The supplementary charge consists of 0.3 pound of TNT. Most deep cavity projectiles are assembled with supplementary charge, spacers, and closing plug; however, some rounds of earlier manufacture were assembled with supplementary charge and PD fuzes or unfuzed without supplementary charge but fitted with a closing plug.
