Armament
The Ayanami class was a destroyer class built for the Japan Maritime Self-Defense Force (JMSDF) in the late 1950s. The primary purpose was anti-submarine warfare , so this class was classified as "DDK" (hunter-killer anti-submarine destroyer) unofficially.[ 1]
Design
This class adopted a "long forecastle" design with inclined afterdeck called "Holland Slope" , named after the scenic sloping street in Nagasaki City.[ 2] Their steam turbine propulsion systems were similar to the ones of the Harukaze class , but they varied between each ship in the class as part of the JMSDF's attempt to find the best propulsion system for its future surface combatants.[ 3]
The Ayanami class were the first JMSDF vessels equipped with six 3-inch/50 caliber Mark 22 guns with Mark 33 dual mounts and Mark 32 lightweight torpedoes with two Mark 2 over-the-side launchers.[ 4] 3-inch guns were controlled by two Mark 63 GFCSs.[ 5]
All seven vessels names had previously been borne by ships of the World War II-era Fubuki and Yūgumo -class destroyer classes.
