US 3"/50 Naval Guns
 

Destroyers that were modernized during the Fleet Rehabilitation and Modernization (FRAM) program of the 1960s had their 3-inch (76 mm) guns removed. In 1992, the USCGC Storis (WMEC-38) 3"/50 caliber main battery was removed from the cutter. It was the last 3"/50 caliber gun in service aboard any US warship. The gun is still in service, however, on select warships of the Philippine Navy.
