Mitsubishi Heavy Industries Maritime Systems has officially delivered the fifth Miyako-class large patrol vessel, JCG Goto (PL-205), to the Japan Coast Guard at its Tamano shipyard in Okayama Prefecture. The handover highlights Japan’s ongoing efforts to strengthen its maritime security and expand its patrol fleet as regional maritime activity becomes more complex. Once commissioned, the Goto will join the Nagasaki Coast Guard Office under the 7th Regional Coast Guard Headquarters, where it will handle missions such as territorial water protection, maritime rescue, law enforcement at sea, maintaining public order, and safeguarding Japan’s marine resources. The Goto follows earlier deliveries from Mitsubishi’s Tamano facility, including the lead ship Miyako (PL-201), Osumi (PL-202), and Amami (PL-204). The fourth vessel, Yaeyama (PL-203), was built separately by Japan Marine United Corporation at its Isogo shipyard in Yokohama. Mitsubishi has also launched two more vessels in the class: Daito (PL-206) and Hiroshima (PL-207). These ships are currently being outfitted with propulsion systems, electrical equipment, and weapons, and are expected to be delivered in late 2025 and 2026. Japan plans to operate up to nine Miyako-class patrol vessels by 2028, according to its 2024 supplementary coast guard budget. Each Miyako-class vessel measures 117 meters in length and has a 3,500-ton capacity. They are equipped with two 40 mm machine guns and powered by four Yanmar 8EY33W diesel engines producing 24,000 horsepower, enabling speeds above 25 knots. While official range figures are not disclosed, the class is expected to exceed the earlier Shikishima-class vessels, which travel around 20,000 nautical miles.
