Greece went through three types of DD from 1912 -
A RN M Type - the Kikládhes (Cyclades Is.) Class
A RN S Type in 1918 - Ionian Is. Class
A RN V&W type in 1920 to serve as Leaders - Kanaris Class (ex Medusa)
The V&W type was developed into the following;
DD1921 - Doxa Class, GREEK Destroyer laid down 1921
