BMT, renowned for its world-leading expertise in maritime engineering and excellence in ship design, and JMU, with its long-established track record in constructing high-performance defence platforms, form an outstanding team for this venture. This partnership represents a significant collaborative effort between the United Kingdom (UK) and Japan.
The groundbreaking program showcases close cooperation between JMU and BMT, with the Caimen ® Landing Craft design provided by the BMT team in the UK, and the production design and construction of the vessels carried out at JMU’s facilities in Japan.
The design of the next-generation High Speed Landing Craft introduces unparalleled operational advantages over existing models. At approximately 30 metres in length, she boasts a highly efficient tri-bow hull form, resulting in outstanding seakeeping, performance, and beaching capabilities. This innovative design, born from extensive research and development of Caimen® Landing Craft, propels the vessel to speeds over 20 knots, ensuring rapid deployment in critical situations.
Additionally, she offers extensive vehicle and troop-carrying capabilities, significantly enhancing operational flexibility and efficiency for military operations. This versatility and superior performance make it an invaluable asset for the Japan Self Defense Force, ensuring that personnel and equipment can be delivered swiftly and safely under various maritime conditions.
