An armor-piercing (AP) shell is a type of ammunition designed to penetrate armor. From the 1860s to 1950s a major application of armor-piercing projectiles was to defeat the thick armor carried on many warships. From the 1920s onwards armor-piercing weapons were required for anti-tank missions. Shot and shell are typically used to denote an artillery projectile and are used to defeat heavily armored tagets such as tanks bunkers and armored warships.
