During the 1960's the Akizuki and her sister Teruzuki lost the Mk.108 Weapon Alpha ASW and it was replaced with a quadruple ASW rocket-launcher from Bofors. This system was widely used by France, Sweden, the Netherlands and other countries.
The ships also had Mk.32 ASW torpedo tubes and a VDS was installed. It was SQA-10 using the SQS-35 body and was known in Japanese service as OQA-1A (Akizuki and Teruzuki OQA-1B)
And here is Teruzuki after her MLU
