JDS Iwase (DE-219) was the fifth ship of the {{sclass|Chikugo|destroyer escort}}s of Japan Maritime Self-Defense Force.
Development and design
The Chikugo class was designed as the modified variant of the {{sclass|Isuzu|destroyer escort|4}}, the preceding destroyer escort class. The main anti-submarine (ASW) weapon was changed from the M/50 {{convert|375|mm|in|abbr=on}} ASW rocket launcher to the ASROC anti-submarine missile. The octuple launcher for ASROC was stationed at the mid-deck, and the entire ship design was prescribed by this stationing.{{Cite journal|last=Abe|first=Yasuo|date=May 2003|title=Looking back on Chikugo class escort vessels|journal=Ships of the World|language=Japanese|publisher=Kaijinn-sha|issue=610|pages=92–97}}
