Ikazuchi-class Destroyer Escort

The Ikazuchi-class Destroyer Escort (いかづち型護衛艦 Ikazuchigata goeikan) was a destroyer escort (or frigate) class built for the Coastal Safety Force (later Japan Maritime Self-Defense Force, JMSDF) in the late 1950s.

In the FY1953, the Japanese government ordered three destroyer escorts, JDS Akebono (DE-201) and this class. These vessels were the first indigenous post-World War II Japanese destroyer escorts, but their propulsion systems were different because the JMSDF tried to find the best way in the propulsion systems of future surface combatants. Akebono was a steam-powered vessel, but this class was diesel-powered vessels.

So equipment of this class were almost the same as those of the Akebono, with two American 3"/50 caliber Mk.21 guns (or Type 54, the Japanese version) with two Mk.22 single mounts controlled by Mk.51 director each, four Bofors 40mm anti-aircraft guns with two dual mounts, a Hedgehog anti-submarine mortar and eight K-gun depth charge throwers. And in 1959, all Mk.21 guns were replaced by Mk.22 rapid-fire guns with Mk.34 single mounts and Mk.63 GFCS was introduced in exchange of the reduction of Bofors 40mm guns.

This class had a twin-shaft machinery installation with two diesel engines (6,000ps each). This propulsion system was less powerful than the steam turbine machinery of the Akebono, but it was able to propel the ship at a top speed of 26 knots (48.15 km/h; 30 mph) still. The JMSDF appreciated the lower cost of maintenance of machinery of this class, so every Japanese destroyer escorts adopted diesel propulsion system until the period of gas turbine powered vessels.
