Description

edit

The Canon de 130 mm Modèle 1924 had an autofretted built-up barrel and a Welin breech block. Useful life expectancy was 900 effective full charges (EFC) per barrel. These guns were carried in low-angle single turrets on destroyers. They had an automatic spring rammer, but loading was difficult at elevations over 15°.[1]
