The Japanese Marine Self-Defense Forces have commissioned a tenth submarine of the Soryu type. The ceremony took place on March 18 at the naval base in Kobe. The unit was built by a shipyard belonging to the Japanese industrial group Kawasaki Heavy Industries. The ship was named Shōryū.
Construction of the tenth Sōryū unit for the Japanese Navy began at the end of May 2015, and its launch took place in November 2017. The ship entered service within 16 months of being launched, notes the industry website navaltoday.com.
