The 5"/38 gun was the ubiquitous dual-purpose mount throughout the United States navy in World War Two. Used well into the 1980's, this gun was the finest DP gun of the war, and one of the best of all time. This weapon was made even more effective when coupled the proximity-fused round when used in an AA capacity. The 5"/38 was also used by the Royal Navy, as well as some in other foreign service, and was still being issued as late as the 1960's.
