JS Haruna

These ships were Japan's first helicopter-equipped destroyer (DDH), and their greatest feature was that it can carry and operate three helicopters in spite of its 5000t class. Such ships, including the development-improved Shirane-class destroyer, can be said to be the only one in the world to this day, and strongly reflect Japan's special military ideology. In terms of equipment, it was the first self-defense ship to be equipped with a fin stabilizer to stabilize its attitude during helicopter operation, and a landing restraint device (bear trap) was installed to improve the safety and efficiency of flight work on a swaying ship.

Until the introduction of the Kongō-class destroyer (Aegis ship), this class (including the Shirane-class destroyer) were the largest escort ship of the JMSDF.
