The Mark 38 25 mm machine gun system (MGS) is a shipboard weapon system designed to protect warships primarily from a variety of surface threats, especially small, fast surface craft.[1] It consists of an M242 Bushmaster chain gun mounted on a turret that can be either manually or remote controlled, depending on variant.[2][3] Originally designed by the United States in the 1980s for use on their warships,[3] the Mark 38 is today in service on warships of various NATO countries.[4]
