Yahagi (やはぎ) is a frigate of the Japan Maritime Self-Defense Force, and the fifth ship of the Mogami class. Her namesake comes from the Yahagi River, which flows through Nagano, Gifu, and Aichi prefectures,[1] a name that was chosen by Defense Minister Nobuo Kishi after a competition within the Maritime Self-Defense Forces.[1]

She is the third Japanese warship to bear this name, following the former Imperial Japanese Navy's Chikuma-class cruiser Yahagi of 1911, and the Agano-class cruiser Yahagi of 1942, though the kanji characters are different, as the former Imperial Japanese Navy's Yahagi was named after the old name of the Yahagi River.

History

[edit]

Yahagi was ordered in the fiscal year 2020, based on the Mid-Term Defense Program, with her keel being laid down at Mitsubishi Heavy Industries Nagasaki Shipyard on 24 June 2021,[2] and was launched on 23 June 2022.[1] After undergoing fitting out and sea trials, the ship was commissioned on 21 May 2024,[3][a] assigned to the Escort Fleet 14th Escort Division of Maizuru.[5][better source needed]

The Mogami-class frigates were designed to be multi-functional in various roles, to address the growing peacetime surveillance and monitoring activities around Japan, including anti-submarine, anti-aircraft, surface, and mine warfare.[1]

Yahagi made a port call at Darwin on 5 June 2025 for comparison against the German MEKO A-200 design as part of the Australian general purpose frigate program.[6]
