The Asahi-class destroyer is a destroyer class of the JMSDF - two ships are planned. The Asahi class is optimized for undersea threats. This class used to be designated "25DD" - referring to a date on the Japanese calendar, specifically the 25th fiscal year of the Heisei period (2013). It is the third ship to hold the name after the Asahi-class destroyer escort lent from the US Navy in 1955, and the Imperial Japanese battleship. Shiranui is the third ship to hold the name after the Murakumo and Kagero-class destroyers.

Development:
The procurement of the destroyer began in 2013 in response to the reduction in the number of destroyers (namely the Hatsuyuki class) within the JMSDF. The two major characteristics of this destroyer is its bigger emphasis on anti-submarine warfare and the adoption of the COGLAG (combined gas turbine electric and gas turbine) propulsion system. A second destroyer was procured a year later.

Design:
The Asahi class is based on the existing Akizuki-class destroyer to reduce acquisition cost and allow future development and growth. Unlike the Akizuki class (which focuses on anti-aircraft warfare) the Asahi class focuses on anti-submarine warfare.

Features:
The Asahi class is the first Japanese warship to be equipped with a COGLAG propulsion system. This allows the destroyer to be more fuel efficient than previous warships. Another unique feature about this destroyer is the usage of a GaN-AESA (gallium nitride - active electronically scanned array) Multifunction Radar. The Asahi class is the second Japanese class of warship to be outfitted with this technology (the Akizuki class was the first). The destroyer's radar is based on the FCS-3A radar used for the Akizuki class and uses gallium nitride to improve performance. In radar technology, gallium nitride offers a number of advantages over the traditionally used gallium arsenide (GaA). These advantages include higher power density, efficiency, thermal spreading and frequency coverage. This in turn allows the GaN chip to be smaller than their GaA counterpart, thus reducing cost and increasing overall cost effectiveness.
