Soryu-class submarines are the world’s largest conventionally powered submarines. They have an excellent operational track record and are equipped with state-of-the art technologies, including Air-Independent Propulsion (AIP) systems that enable them to remain fully submerged for long periods of time, and advanced stealth technologies that make them extremely difficult to detect.
