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.
