flagshipicon Jupiter '42 - British Tier VII Premium Destroyer 1939

A J-class ship, distinct from the earlier generation of "conventional" destroyers, featuring a unique layout, larger size, and more powerful weaponry. 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.

Key Features:

Similar to her sister ship Jervis, Jupiter is armed with six 120mm guns. She has improved characteristics in the form of better reload, improved AP ricochet angles (identical to those found on British destroyers Jutland and Daring, for example), and longer-range torpedoes, but in exchange has only one torpedo launcher, low damage per torpedo, less fire chance on her HE shells, and worse concealment.


Jupiter will play effectively as a second-line destroyer, helping her stealthier compatriots duel enemy destroyers. Her gunpower can also be put to good use harassing enemy capital ships, but captains will want to be careful as she lacks killing power in the form of torpedoes to finish them off.
