Generally, the penetration capability of an armor piercing round is proportional to the projectile's kinetic energy.
The armour-piercing concept calls for more penetration capability than the target's armour thickness.
Generally, the penetration capability of an armor piercing round increases with the projectile's kinetic energy and also with concentration of that energy in a small area.
During additional tests it showed excellent penetration capabilities: it could penetrate 40mm of steel armour at 200 metres distance.
Also, she can combine with Kaguya's power to make up a bow and arrow weapon which has a high penetration capability.
The key feature of the weapon was its high muzzle velocity which enabled high accuracy and good penetration capabilities.
The 17-pounder was of a similar bore, but had far superior armor penetration capability.
Total penetration capabilities are classified, but are known to be at least 550mm in rolled homogeneous armor.
Besides enhanced penetration capabilities these overpressure variants offer a flatter trajectory and lessened recoil.
Due to its low penetration capability, it's mostly used against light armored targets.
