From the frigid waters of the North Sea to the steamy shoals of the South Pacific, DESTROYER COMMAND puts you in charge of one of the proudest and most versatile ships which ever put to sea: the U.S. Navy destroyer.
During World War II U.S. Navy destroyers fought German U-boats in a grim battle for the waters of the North Atlantic. In the Pacific, destroyers battled Japanese warships in vicious night actions, fended off desperate kamikaze attacks and supported the U.S. Marine landings which pushed the invaders inexorably back to their homeland.
Experience for yourself the challenges of a career as a destroyer captain in DESTROYER COMMAND's dynamic campaigns. Fight the whole of World War II in either the Atlantic or Pacific theater. As you advance in rank you can take charge of a whole division or squadron of destroyers, or you can choose to finish the campaign commanding a single ship.
