127 mm artillery

The term "127 mm artillery" typically refers to artillery pieces that have a bore diameter of 127 millimeters (mm). This caliber is often associated with naval guns rather than traditional ground-based artillery. A notable example of a 127 mm naval gun is the American Mark 45 naval gun, which is widely used on various classes of U.S. Navy destroyers and cruisers. It is designed for engaging surface ships, land targets, and is also capable of launching guided munitions.
