The Murasame-class destroyer was a destroyer class built for the Republic of Japan Navy (RoJN) in the late 1950s as a successor to the Ayanami-class destroyers. Like its predecessor, its main task was anti-submarine warfare, but its improved weaponry also enabled it to perform better in the anti-air role, so this class was classified as "DDA" (anti-air destroyer or all purpose destroyer) unofficially.
Like its predecessor Ayanami-class, this class adopted a "long forecastle" design with inclined afterdeck called "Holland Slope", named after the scenic sloping street in Nagasaki City. The propulsion system was almost the same as the one of the Harukaze class destroyer.
The sensor suite and weapon system was almost the same as the one of the latter batch of the Ayanami-class, but three QF 4.5"/45-caliber Mk.V dual purpose naval guns were added to extend effective range against air and surface threats in addition to four Vickers Mk.6 3"/70-caliber guns. 4.5 inch guns were controlled by one Mark 57 GFCS, and 3 inch guns were done by one Mark 63. Main air-search RDF was OPS-1.
