Construction and career

Ōryū was laid down at Mitsubishi Heavy Industries Kobe Shipyard on November 16, 2015, as the 2015 plan 2900 ton type submarine No. 8126 based on the medium-term defense capability development plan (23 medium-term defense). In October 2018, the submarine was named and launched on 4 October. The delivery ceremony and the self-defense ship flag awarding ceremony were held on 5 March 2020, and it was commissioned. It was incorporated into the 1st Submarine Flotilla and deployed at Kure Naval Base.^[2]^[3]

Ōryū bears the distinction of being the first submarine launched with Lithium-ion batteries, which replaced the AIP Stirling engine system used in the other submarines of the Sōryū-class submarines.
