Japanese Soryu submarine JS Hakuryu in Sydney Harbour, April 15, 2016 (Photo above and below courtesy of Australia's ABC)
Accompanying that submarine (in what is a small fleet (flotilla)) are destroyers:
- JS Asayuki (DD132) of the Hatsuyuki-class, and
- JS Umigiri (DD158) of the Asagiri-class
Each of these destroyers has a SH-60J(K) helicopter for mainly anti-submarine uses.
Commissioned 1991. At 5,000 tons full load thisAsagiri class destroyer weighs 1,000 tons more than JS Asayuki's/Hatsuyuki class. Asagiri class range/speed is 14,870 km at 14 knots. Same armament and helicopter type as JS Asayuki (DD-132). (Photo courtesy qianzhan.com)
These Japanese vessels should not be confused with a separate Japanese submarine, 2 destroyer, flotilla (submarine JS Oyashio, destroyers JS Setogiri and JS Ariake) that visited Subic Bay, Phillippines and then destroyers JS Setogiri and JS Ariake visited Cam Ranh Bay, Vietnam, in early April. That separate flotilla has probably returned to Japan.
