Coast Guard Cutter Sherman crewmembers lay ashore during the Sherman’s decommissioning ceremony in Honolulu, Mar. 29, 2018. The Sherman was the last remaining active Coast Guard war ship to have sunk an enemy ship in combat when its crew sank a North Vietnamese naval trawler during the Vietnam War by firing eight rounds from its 5” gun in 30 seconds.
