Ship History
Built by Yarrow & Company at Scotstoun in Glasgow. Laid down September 20, 1937. Launched October 27, 1938. Commissioned June 16, 1939.

Wartime History
During 1940 and 1941 participated in missions in the European Theater of Operations (ETO) including:  Minelayer operations of Dutch coast, shelling of Cherbourg and the British raid on Genua.

On November 29, 1941, the HMS Jupiter and HMS Encounter, detached from the Mediterranean Fleet and join Force G at Colombo Harbor on Ceylon (Sri Lanka) and the five ships departed later that day. They rendezvoused with HMS Repulse at sea, and set course for Singapore, arriving on December 2, 1941.

On January 17, 1942, Jupiter sank a Japanese I-60 submarine.

Sinking History
On February 27, 1942 participated in the Battle of the Java Sea. During the evening Jupiter was streaming near the northern coast of Java and suffered a violent explosion and sank. At the time, the explosion was thought to be a Japanese torpedo. But, there where no Japanese forces in striking distance at the time of the explosion.  Later it was found that she had entered a minefield and struck an Allied mine laid earlier that same day by Dutch minelayer Gouden Leeuw.

The shipwreck is near to northern coast of Java. Shipwreck known prior to 2002, discoverers unknown. The wreck is very broken up and noted on British Admiralty charts. The shipwreck has been extensively salvaged.

Kevin Denlay adds:
"Jupiter is the only one of all the Battle of the Java Sea wrecks (2/27/42) that I haven't dived. Skipper has dived her many years ago and reports very very broken up from salvage and extremely poor vis, what we would call 'braille' diving. And its a little out of the way being right down on the coast, so although I would like to dive her just to complete the circle as it were, it's not something I expect to happen any time soon."
