”Soft caps” are AP caps made out of soft metal and is was original design in use. Unlike hard caps, soft caps primarily only helps with protecting the penetrator on impact.<ref name=”navweaps”>http://www.navweaps.com/index_tech/tech-055.htm</ref> They function by spreading the radial shock outward from the impact along the radius of the now flattened soft cap, keeping the shock from traveling into the body of the shell itself.<ref name=”navweaps”/> Soft caps, however, does not function at high impact angles. Starting at obliquities of 15°, they begin to be torn free prior to functioning, and stops fully functioning over obliquities of 20°.<ref name=”navweaps”/>

Following [[WWI]], soft caps started being discarded for naval shells. One reason being their inability to function at high impact angles, but also because of improved [[metalurgy]] following the war, which had lead to [[face-hardened]] armor that could negate soft cap projectiles.<ref name=”navweaps”/> When impacting tough [[face-hardened]] armor with a soft cap projectile, the soft cap will project the penetrator on the initial impact, but due to the properties of [[face-hardening]] (hard surface, soft spongy depth), once the penetrator passes through the soft cap and hits the armor, the hardened surface backed up by the soft depth plate will be unable to effectively cave in, which in short leads to the penetrator being destroyed by the crushing forces surrounding it.<ref name=”navweaps”/>
