After the ''Gearing''-class ships were retired from USN service, many were sold abroad, including over a dozen to the [[Republic of China Navy]] (ROCN) in [[Taiwan]]. These ships, along with ''Fletcher''-class destroyers and ''Allen M. Sumner''-class destroyers also acquired then, were upgraded under the Wu&nbsp;Chin ({{zh|c=武進}}) I, II, and III programs and known throughout the ROCN as the Yang-class ({{zh|c=陽字號}}) destroyers as they were assigned names that all end with the word "Yang".  The last batch of 7&nbsp;WC-III program vessels, all of them ''Gearing'' class, were retired in the early 2000s.<ref>{{cite web|author=John Pike |url=http://www.globalsecurity.org/military/world/taiwan/chao-yang.htm |title=Chao Yang-class [Gearing&#93; Destroyer - Republic of China [Taiwan&#93; Navy |publisher=Globalsecurity.org |access-date=2012-08-17}}</ref>

Under the most advanced Wu Chin III upgrade program, all World War II vintage weapons were removed and replaced with four [[Hsiung Feng II]] surface-to-surface missiles, ten [[Standard Missile|SM-1]] (box launchers), one 8-cell ASROC, one [[Otobreda 76 mm|{{cvt|76|mm|in|0}} Otobreda gun]], two Bofors 40&nbsp;mm AA, one [[Phalanx CIWS|20 mm Phalanx CIWS]] and two [[Mark 32 Surface Vessel Torpedo Tubes|triple {{cvt|12.75|in|0}} torpedo tubes]]. The DASH ASW drones were not acquired, but hangar facilities aboard those ships that had them were later used to accommodate of [[MD 500 Defender|MD 500/ASW helicopters]].

After the Yang-class destroyers were decommissioned, the SM-1 launch boxes were moved to [[Knox-class frigate|''Chi Yang''-class frigates]] to improve their anti-air capability.
