A J-class ship, distinct from the earlier generation of "standard" destroyers, featuring a novel layout, larger size, and more powerful armament. HMS Jupiter initially served in the Home Fleet before being shifted to the Mediterranean. Starting in December 1941, the ship joined Allied operations in Southeast Asia, and it was in this region that she sent a Japanese submarine to the bottom. On February 27, 1942, Jupiter was lost when she hit a mine during the Battle of the Java Sea and sank.
