During the war the IJN found out (the hard way) that small and cheap escorts are essential, and this resulted in the Tachibana class (see here
one of which was raised after the war and used as trials ship.
The idea of a small escorts was revived in 1955 with the 'B' type the Akebono
This ship had steam turbines while others had diesels, and that is why the Akebono has two funnels.
The ship is armed with 2 3"/50 in single mountings, 2 40mm guns in a twin mounting and one Mk.11 Hedgehog and depth charges, all armament and electronics are of American origin.
