JS Tōryū (SS-512) is the twelfth boat of Sōryū-class submarines. She was commissioned on 24 March 2021.

Construction and career[edit]

Tōryū was laid down on January 27, 2017, at Kawasaki Heavy Industries Kobe Works as the 2016 plan 2900 ton type submarine No. 8127 based on the medium-term defense capability development plan (23 medium-term defense), and launched November 6, 2019. The naming and launching ceremony was held on that day.^[2]^[3]

Tōryū is the second submarine in class to follow the lead of the Ōryū. Both bear the distinction of being the first and second submarines launched with Lithium-ion batteries, which replaced the AIP Stirling engine system used in the other boats of the Sōryū-class submarines.
