context_page_description: The Sōryū-class submarines are diesel-electric attack submarines. The first boat in the class entered service with the Japan Maritime Self-Defense Force in 2009. The design is an evolution of the Oyashio-class submarine, from which it can most easily be distinguished by its X-shaped stern combination diving planes and rudders. The Sōryūs have the largest displacement of any submarine used by post-war Japan.
  It is Japan's first air-independent propulsion submarine. From Sōryū to Shōryū are fitted with Kockums Naval Solutions Stirling engines license-built by Kawasaki Heavy Industries, allowing them to stay submerged for longer periods of time. Furthermore, Ōryū is the world's first lithium-ion battery submarine. The cost of the sixth submarine was estimated at 540 million USD.
  In 2019, the replacement to the Sōryūs, the 29SS submarine, entered the planning phase.
context_section_description: Japan offered Sōryū-class submarines to Australia to replace the Royal Australian Navy's Collins-class submarines as part of the Collins-class submarine replacement project. On 9 April 2014, then-Australian Defence Minister David Johnston, while discussing Australia's future submarine options, described the Sōryū class as "extremely impressive". On April 26, 2016, Australian Prime Minister Malcolm Turnbull announced that the Australian contract had been awarded to the French-designed Shortfin Barracuda.
  India and Taiwan have also approached Japan and expressed an interest in buying Sōryū-class submarines. During a visit by India's Defence Minister Manohar Parikkar to Japan he asked the Japanese government to participate in the multi-billion-dollar Project 75I-class submarine project.
