The two retired U.S. Navy Kidd (DDG-993) class destroyers recently added to the Taiwanese Navy are by far the most capable and powerful surface warships ever to enter service with their fleet. Initially offered for sale by the United States in January 2001, the first to be reactivated, Keelung and Suao , sailed for Taiwan in November 2005. The remaining two units, Tsoying and Makung , are expected to enter Taiwanese service early in 2006. Contrary to previous reports, the destroyers appear to have been named after Taiwanese port cities. While in U.S. Navy service, the four were named Kidd (pictured to the right), Callaghan (DDG-994), Scott (DDG-995), and Chandler (DDG-996). The warships have been extensively refitted during their three-year reactivation overhauls, performed at Detyens Shipyard in South Carolina. Total cost for the four destroyers is approximately $800 million. Capable of employing a single antisubmarine warfare helicopter, their primary armament consists of Harpoon antiship missiles, SM-2 Standard surface-to-air missiles and 5-inch guns.
