Фрегати класу New FFM (проєкт)

The New FFM is a frigate class planned to be built for the Japan Maritime Self-Defense Force. These were reordered from 10 Mogami-class frigates, which was planned to have 22 ships before being scaled back to 12. The order for the new ships increased in quantity, and a total of 12 ships are to be built over a five-year period from the fiscal year of 2024.

The Japan Maritime Self-Defense Force began constructing the Mogami-class (30FFM) frigates from 2018. These vessels were designed for mine countermeasure operations in addition to various littoral missions currently undertaken by destroyers and destroyer escorts of the 10th Escort Squadron, which is not part of the Fleet Escort Force. The original plan was to build 22 ships to replace the eight destroyers and six destroyer escorts of the 10th Escort Squadron, as well as the eight minesweeping vessels of the Mine Warfare Force.

However, on 25 January 2023, the Defense Acquisition Agency announced the «Guidelines for soliciting participants for the 'Planning and Proposal Contract for New FFMs'», and construction from fiscal year 2024 onwards would switch to the new ships. On 31 March of the same year, Japan Marine United and Mitsubishi Heavy Industries completed the planning contract. The government, having received proposals from each company on 15 June, decided on 25 August the procurement partner for the class, with MHI being the main supplier, while the JMU would be the subcontractor. On 31 August of the same year, a total of 12 new FFMs were to be built starting with the 2024 planned ships, and 174.7 billion yen will be invested into the construction of two ships in the following fiscal year's budget. The first two ships are scheduled to be commissioned in 2028.

On 11 April 2025, it is reported that the first FFM was already being fitted with the Mk 41 VLS.

The Mogami-class frigates are being built at a rate of two ships per year, but the new FFMs will be built at a faster pace, with a total of 12 ships planned to be procured over a five-year period from 2024 to 2028.
