The 127/54 Compact was developed in the 1960s and set up specifically for use on destroyers . It fires the 127 mm naval weapons projectiles standardized in NATO. In the 1990s, Oto Melara began developing a lighter and more powerful version, the 127/64 Lightweight , for use on smaller warships. This version with a caliber length of 64 and lower weight is intended to enable greater ranges with a lower tower weight.
