Mitsubishi Heavy Industries Maritime Systems has delivered the fifth Miyako-class patrol vessel, JCG Goto (PL-205), to the Japan Coast Guard at its Tamano facility in Okayama Prefecture.
After entering service, the Goto will be assigned to the Nagasaki Coast Guard Office under the 7th Regional Coast Guard Headquarters, supporting missions including safeguarding territorial waters, conducting search and rescue, maintaining maritime order, and protecting marine resources.
This latest vessel follows three Miyako-class ships previously built at Mitsubishi’s Tamano plant—JCG Miyako (PL-201), JCG Osumi (PL-202), and JCG Amami (PL-204).
The fourth vessel, Yaeyama (PL-203), was constructed by Japan Marine United Corporation at its Isogo shipyard in Yokohama, Kanagawa Prefecture.
Earlier this year, Mitsubishi launched the sixth and seventh vessels in the class, JCG Daito (PL-206) and JCG Hiroshima (PL-207).
Following the completion of hull outfitting, engine installation, electrical systems, and onboard weapons, the two ships are scheduled for handover in late 2025 and 2026.
Japan aims to field up to nine Miyako-class patrol vessels by 2028, as outlined in the 2024 supplementary budget for the coast guard.
Miyako-Class Features
Each Miyako-class vessel is 117 meters (384 feet) long and has a standard cargo capacity of 3,500 tons (3,175,147 kilograms).
They are outfitted with two 40-millimeter machine guns and powered by four Yanmar 8EY33W diesel engines producing 24,000 total horsepower.
The vessels can travel at speeds exceeding 25 knots (46 kilometers/29 miles per hour).
Though official endurance figures have not been released, the class is anticipated to surpass the operational range of the Shikishima-class, which can reach roughly 20,000 nautical miles (37,040 kilometers/23,016 miles).
