Development and design

The Chikugo class was designed as the modified variant of the Isuzu class, the preceding destroyer escort class. The main anti-submarine (ASW) weapon was changed from the M/50 375 mm (14.8 in) ASW rocket launcher to the ASROC anti-submarine missile. The octuple launcher for ASROC was stationed at mid-deck, leading the entire ship design.[1]
