JS Hiei (DDH-142) was the second ship of the Haruna-class helicopter destroyer of the Japanese Maritime Self Defense Force.
See main article: Haruna-class destroyer. The Haruna-class ships were Japan's first helicopter-equipped destroyers (DDH), and their greatest feature was that they could carry and operate three helicopters in spite of their 5000t class. Such ships, including the development-improved Shirane-class destroyer, can be said to be the only ones 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) was the largest escort ship of the JMSDF.
Hiei was laid down on 8 March 1972 and launched on 13 August 1973 by IHI Corporation Tokyo Shipyard. She was commissioned on 27 December 1974, into the 1st Escort Corps and deployed in Yokosuka.[1]
From July 3 to August 17, 1978, she participated in Hawaii dispatch training with her sister ship JDS Haruna, JDS Kuroshio and eight P-2J aircraft.
JDS Hiei, JDS Amatsukaze and eight P-2Js were dispatched to the United States from January 25, 1980, and participated in the Exercise RIMPAC 1980 exercise between February 26 and March 18. They were the first ships to participate from Japan. Returned to Japan on April 2.

On March 30, 1984, she was incorporated into the 4th Escort Corps as a flagship.
The FRAM refurbishment carried out from August 31, 1987 to March 13, 1989 improved anti-submarine search capability, individual ship air defense capability, combat command / information processing capability, and electronic warfare capability. However, the cost-effectiveness of FRAM refurbishment was not efficient, and similar large-scale refurbishment was only carried out on two Haruna-class vessels.
On March 2, 1995, due to the relocation of the 4th Escort Group Command to Kure, the homeport was transferred to Kure.
