As the threat from kamikaze aircraft mounted in 1945, and with few remaining Japanese warships to use torpedoes on, most of the class had the after quintuple 21" torpedo tube mount replaced by an additional 40 mm quadruple mount (prior to completion on later ships) for 16 total 40mm guns. In place of mount 52, a practice 5 inch reloading machine was installed with the MK-32 triple torpedo launchers aft of the loader. Twelve 40 mm guns and 11 20 mm guns were also retained.
