Minegumo-class Destroyer
The ''Minegumo''-class destroyer is a destroyer class of the Japanese Maritime Self-Defense Force, the successor of the . This class derived from its predecessor to be fitted with the QH-50D DASH, the new anti-submarine drone helicopter in return for the removal of the ASROC system. And similarly, it mainly tasked with Anti-submarine warfare. In 1969, after the production of the QH-50D ceased, this class was no longer built and construction of the ''Yamagumo''-class resumed. The JMSDF considered refitting Light Airborne Multi-Purpose System Mk.1 with the Kaman SH-2 Seasprite helicopter in return for the facility of DASH, but this plan was abandoned because of the problem of cost. Finally, the facility of DASH was removed in 1979-82, and Mk.16 GMLS for the ASROC system was fitted. Murakumo was refitted in 1978 for use as a gun trials ship. Rear Mk.33 gun was removed and a new OTO Melara 76 mm The OTO Melara 76 mm gun is a naval gun built and designed by the Italian d ...

Yamagumo-class Destroyer
The ''Yamagumo'' class are vessels of the Japanese Maritime Self-Defense Force, usually classified as a destroyer, but due to their relatively light displacement, in other sources as a destroyer escort. This class is the successor of the . This class was planned to become the new generation workhorse of the fleet of the JMSDF. In support of this objective, it was equipped with some new generation weapon and sensor systems such as the ASROC anti-submarine rocket and the OPS-11 early warning radar (Japanese equivalent of the American AN/SPS-40 radar). The ''Minegumo''-class destroyer derived from this class as the new DASH The dash is a punctuation mark consisting of a long horizontal line. It is similar in appearance to the hyphen but is longer and sometimes higher from the baseline.

Haruna-class Destroyer
The ''Haruna''-class destroyer was a destroyer class built for the Japan Maritime Self-Defense Force (JMSDF) in the early 1970s. These helicopter carrying destroyers (DDH) are built around a large central hangar which houses up to three helicopters. Originally, the Coastal Safety Force and its successor, the JMSDF, had intended to enable its fleet aviation operating capability. In 1960, the Defense Agency planned to construct one helicopter carrier (CVH) with the Second Defense Build-up Plan, but this project was shelved and finally cancelled because the JMSDF changed their plan to dispersing its fleet aviation assets among destroyers, not concentrating in a few helicopter carriers. The Japanese DDH was planned to be a hub with this dispersing fleet aviation concept with their logistics service capability for aircraft. At the beginning, equipment of this class were similar to those of the DDA. All weapons, two 5-inch/54 caliber Mark 42 (Type 73) guns and one Type 74 octuple missi ...

JS Hatakaze
The ''Hatakaze'' class of guided-missile destroyers is a third generation class of vessels in service with the Japan Maritime Self-Defense Force (JMSDF). They were the first of the JMSDF's ships to have gas-turbine propulsion. The core weapon suite is similar to that of the preceding , but various improvements were made in many areas. Most notable are those that allow the ''Hatakaze'' class to function as a group flagship. Normally this duty resides with a larger type of ship, but in case of their absence due to repairs, accident, or battle damage, the ''Hatakaze'' design allows for it to function as a command ship. ''Hatakaze'' destroyers operate the OYQ-4-1 type tactical control system. Its weapon systems include the Standard missile surface-to-air missile, anti-submarine rockets, the RGM-84 Harpoon anti-ship missile, two Mark 15 20 mm CIWS gun mounts, two torpedo mounts in a triple tube configuration and two 5 inch/54 caliber Mark 42 rapid-fire guns.

Tachikaze-class Destroyer
The ''Tachikaze''-class destroyer was a second generation guided missile destroyer class, formerly in service with the Japan Maritime Self-Defense Force (JMSDF). The ships of this class have had successive improvements after their completion, especially to their C4I systems. These air-defense warships are the natural successor to the first generation air-defense ship, the , and they were in turn, followed by newer air-defense ships, the . The ''Tachikaze'' class was equipped with the Tartar-D system as the key weapon system, the fleet-area air defense weapon system with the Standard-1 MR missile. At the same time, this was the American first native integrated weapon system with the Naval Tactical Data System (NTDS), so this class was the first of the Maritime Self Defense Force's ships that utilised computers widely. As the NTDS, OYQ-1 Weapon Entry System (WES) was on board on the lead ship, ''Tachikaze''. The OYQ-1 WES was based on the technology of the NYYA-1 which was on boa ...

JS Hiei
JS ''Hiei'' (DDH-142) was the second ship of the ''Haruna''-class helicopter destroyer of the Japanese Maritime Self Defense Force. Overview 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.
