Japan commissions 10th Mogami-class frigate JS Nagara in record time
Mitsubishi Heavy Industries delivered the JS Nagara, the tenth Mogami-class frigate, to Japan's Ministry of Defense on June 29, 2026, at its Nagasaki Shipyard. The 5,500-ton vessel is crewed by just 90 sailors—less than half the personnel required by older Japanese destroyers—thanks to extensive automation designed to address Japan's demographic crisis and recruitment challenges. The ship features a 16-cell Mk 41 Vertical Launch System installed during construction, a 127mm naval gun, SeaRAM CIWS, and multi-mission capabilities. Construction took under three years from keel laying in July 2023. The program is on track to complete all 12 baseline ships by March 2027, with a follow-on 12-ship upgraded class already approved. Australia selected the upgraded Mogami variant in August 2025 for its SEA 3000 program, planning to build 11 frigates, with the first three in Japan and eight domestically in Australia.

Mitsubishi Heavy Industries delivered the JS Nagara, the tenth Mogami-class frigate, to Japan's Ministry of Defense on June 29, 2026, at the Nagasaki Shipyard. The 5,500-ton vessel requires only 90 crew members—less than half of Japan's older destroyers—through extensive automation, addressing Japan's demographic crisis and recruitment challenges. The frigate features a 16-cell Mk 41 Vertical Launch System, a 5-inch gun, SeaRAM close-in weapon system, and anti-submarine warfare sensors. Construction took less than three years (keel laid July 2023). Australia selected an upgraded Mogami variant in August 2025 for its SEA 3000 program to build 11 frigates. Japan plans to complete the baseline 12-ship class by March 2027 and has committed to 12 additional upgraded variants with doubled vertical launch capacity.

The Japan Maritime Self-Defense Force (JMSDF) commissioned its tenth Mogami-class frigate, JS Nagara (FFM-10), on June 29, 2026, at Kure Naval Base. Built by Mitsubishi Heavy Industries for approximately 52.3 billion yen ($323 million), the highly automated warship was inducted into Patrol and Defense Squadron 2. The 5,500-ton frigate features a 16-cell Mk 41 VLS, a stealthy design, and a crew of only 90 sailors—dramatically less than conventional destroyers. Its advanced Integrated Ship Handling System allows one-person maneuvering during berthing and reduces bridge crew to four sailors. The class is designed to replace older destroyers and minesweepers while addressing Japan's personnel shortages. Unmanned systems (UUVs/USVs) will be installed later.

Built by Mitsubishi Heavy Industries at a cost of 52.3 billion yen ($323 million), the ship features advanced automation allowing a crew of just 90 sailors, compared to 200 on conventional destroyers. Key innovations include a four-person bridge team during normal operations and a single-joystick Integrated Ship Handling System enabling one-person berthing without tug assistance. From the seventh vessel onward, the class incorporates a 16-cell Mk 41 Vertical Launching System (VLS). The Nagara is assigned to Patrol and Defense Squadron 2 of the newly established Patrol and Defense Group, underscoring Japan's shift toward a leaner, more technologically advanced surface fleet amid personnel shortages.
