The Japan Maritime Self-Defense Force (JMSDF) commissioned the replacement submarine rescue ship JS Chiyoda in a ceremony held on 20 March in Okayama Prefecture in western Japan.

The 128 m (420 ft)-long ship (with pennant number ASR 404) was inducted into the JMSDF's Submarine Flotilla 2, based in Yokosuka, shortly after being handed over by shipbuilder Mitsui Engineering & Shipbuilding (MES) at its facility in Tamano, the service said in a statement.

The move marks the first time a submarine rescue ship has been inducted into the JMSDF since March 2000 when JS Chihaya (ASR 403) entered service with the force.

The recently inducted ship, which was launched in October 2016, replaces the former JS Chiyoda (AS 405), which was decommissioned on the same day.

According to specifications provided by MES, the new vessel has a speed of 20 kt, a standard displacement of 5,600 tonnes (6,173 tons), a beam of 20 m and a draught of 5.2 m. The ship, which cost JPY53.4 billion (USD504 million) to build, is powered by two diesel engines, each of which generates19,500hp, according to MES.
