Hatsuyuki supplied fleet numbers with an OTO Melara 76 mm gun, Phalanx, Harpoon, Sea Sparrow, ASROC, triple torpedo tubes, and a helicopter in a roughly 4,000-ton ship. Japanese designers accepted a less redundant COGOG machinery layout to get quiet gas-turbine escorts in numbers, then dispersed helicopters across ordinary destroyers. Asagiri continued the pattern with more helicopter-capable ships, better communications, allied interoperability, and a visible global presence. These classes spread aviation, ASW, and air-defence capability beyond the dedicated command ships. Modern JMSDF strength grew from decades of construction, yard improvement, and continued acquisition of workable ships.
