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 aft quintuple 21-inch tube mounts replaced by an additional 40mm quadruple mount (prior to completion on later ships) for 16 total 40mm guns. The Gearing Class Frigate was for all intents and purposes, a missle (sic) boat. The drone could carry two Mark 44 homing ASW torpedoes. Plan NOTES for BT's, the Oil King and other engineers The Gearing design was a minor modification of the immediately preceding Allen M. Sumner class. Some Gearings served in the Naval Reserve Force (NRF) from 1973, remaining in commission with a partial active crew to provide training for Naval reservists. The first Gearings were not ready for service until mid-1945 and saw little service in World War II. DD-858 to DD-861 awarded to Bethlehem Steel, San Pedro.

After the Yang-class destroyers were decommissioned, the SM-1 launch boxes were moved to Chi Yang-class frigates to improve their anti-air capability. In June 1942, the 1.1" gun was replaced by a twin Bofors 40 mm gun mount; in some ships, another twin mount may have been added on the fantail between the depth charge racks. for the 20MM GUNS, location and supporting equipment.
