Niyodo (によど) is a frigate of the Japan Maritime Self-Defense Force (JMSDF), and the seventh ship of the Mogami class. She was named after the Niyodo River,[3] and the second ship to be named so, after the Chikugo-class destroyer escort JDS Niyodo.[4][1] The Imperial Japanese Navy had plans to name the second Oyodo-class cruiser after the Niyodo River, but her construction was cancelled.[3]

Construction and career

[edit]

Niyodo was ordered in March 2022 (for about 47.4 billion yen)[1] by Mitsubishi Heavy Industries as part of the JMSDF's Mid-Term Defense Program and was laid down at MHI's Nagasaki Shipyard on 30 June 2022.[2] She was named and launched on 26 September 2023.[5][1][2] Although the Mk.41 VLS was included in the 2021 supplementary budget, it was decided[by whom?] that it will be fitted later due to the global semiconductor shortage.[6] After fitting out and undergoing a series of sea trials, the ship was scheduled to be commissioned in December 2024.[7] The schedule was later pushed back to the first half of 2025, and according to Kosuke Takahashi, it is uncertain whether or not the delayed commissioning date allowed the Mark 41 VLS to be fitted, or a decision made by the JMSDF to equip the VLS during Niyodo's fitting out process.[8]
