On March 12, the Japan Marine United (JMU) shipyard in Yokohama will officially deliver the mine countermeasure vessel “Nomi” to the Japan Maritime Self-Defense Force (JMSDF). This is the fourth ship of the “Awaji” class and the first of its type built for the JMSDF in the last four years. Laid down in May 2021 and launched in October 2023, “Nomi” is named after the Higashi-Nomi and Nishi-Nomi islands in Hiroshima Prefecture, a tradition for JMSDF mine sweepers. Designed for mine neutralization and ensuring safe passage, “Nomi” is equipped with advanced sensors such as the OPS-39H search radar, the OQQ-10-2 hydroacoustic system, and the variable depth mine detection sonar ZQS-4. Additionally, it features a medium-class unmanned underwater vehicle OZZ-4 for mine searching, a remotely operated vehicle OXX-2 for reconnaissance, and the Mitsui EMD mine disposal system. With a length of 67 meters, a beam of 11 meters, a draft of 2.7 meters, and a standard displacement of 690 tons, “Nomi” is powered by two diesel engines generating a total of 2,200 horsepower, achieving a maximum speed of 14 knots. The crew comprises approximately 50 personnel. Constructed from reinforced fiberglass, the Awaji-class hull reduces the magnetic signature, enhances durability, and lowers maintenance costs compared to conventional hulls, positioning these vessels among the most advanced non-magnetic mine sweepers globally. The lead ship “Awaji” entered service in 2017, followed by “Hirado” in 2018 and “Etajima” in 2021, with the fifth ship projected for service by 2026. The deployment of “Nomi” underscores Japan’s commitment to modernizing its naval capabilities in mine warfare, enhancing maritime security in the region.
