130 mm/40 (5.1") Model 1919
Updated 16 May 2006
Conceived during World War I as being more a powerful weapon than those arming contemporary foreign destroyers.  Its superiority was more theoretical than real, as it had a slow rate of fire for a destroyer weapon and was difficult to load at low angles of elevation.
