   The Haruna class and follow-on improved Shirane class were the world's first destroyer-sized warships designed to carry and operate three large Sea King-sized ASW helicopters. Both ship classes were completed with strong ASW armaments, though as built they were weaker than most contemporary Western designs in both anti-air and anti-surface warfare systems. To help rectify these shortcomings, both classes were refitted in the late 1980s and early 1990s. The Haruna class destroyers had 20-mm Phalanx CIWS and Sea Sparrow missile systems added to improve anti-aircraft and anti-missile point defense.

   The Haruna class, comprising Haruna (DD 141 and Hiei (DD 142), were completed in 1973 and 1974. They have continuous superstructures. Their single combined radar mast and funnel (known as a 'mack') offset to port allow space for the third helicopter in the hangar.

   The Haruna nad Hiei were planned to be decommissioned in 2008 and 2009 respectively. These ships had an operational life of about 35 years and will be replaced with the new Hyuga class helicopter carriers.
