J or JAVELIN-Class Destroyer ordered from Fairfields at Govan, Glasgow on 25th March  1937 under the 1936 Build Programme and laid down on 5th October 1937 and intended to be named JAMAICA. However the name was changed to JUNO before launch on 8th December to allow the selected name to be given to a new COLONY Class cruiser. The new name had been introduced in 1757 for a 5th Rate and last used for a cruiser built in 18945 and sold in 1920. This destroyer was the 9th to carry the name. Build was completed on 25th August 1939
