Between June 1978 and May 1979, Litton Industries laid keels for these four ships at its Pascagoula, Mississippi shipyard. On 1 April 1979, meanwhile, the Iranian people voted in national referendum to replace the Pahlavi dynasty with an Islamic Republic under Ayatollah Ruhollah Khomeini. The new government soon canceled its order, placing the ships’ future in doubt. After a vigorous debate in Congress, however, they were completed and delivered to the US Navy in 1981–82 as Kidd, Callaghan, Scott and Chandler (DDGs 993–996), all named for admirals lost during the Pacific war.

From the beginning, the Kidds’ designers contemplated operations in the Persian Gulf where heat, dust and sand were factors. Accordingly, they received four air conditioning plants rather than the Spruances’ three, additional dust separators on their gas turbines’ air intakes and increased water distillation capacity. To the Spruances’ anti-submarine capabilities, they added two Tartar-D missile launchers—modifications that increased displacement by 700 tons but also earned them contemporary acclaim as the US Navy’s best destroyers ever.
In 1988–90, the Kidds’ air defenses were enhanced with a “New Threat Upgrade.” This included a new superstructure and heavier mainmast that somewhat detracted from their appearance but enabled cooperative engagement with Aegis cruisers and the soon-to-arrive Arleigh Burke-class Aegis destroyers, which could control the Kidds’ surface-to-air missiles while they remained electronically silent.
As in the case of the Spruances, however, delivery of the more cost-effective Arleigh Burkes shortened the Kidds’ US Navy careers. They were decommissioned in 1997–99, when it appeared Greece might acquire them to replace its four ex-Charles F. Adams-class destroyers until it declined in November 1999. Following Congressional authorization in 2001, however, the four Kidds were reactivated, upgraded and recommissioned in 2005–06 as the Republic of China (Taiwan) Navy’s Kee Lung class: Kee Lung (ex-Scott), Su Ao (ex-Callaghan), Tso Ying (ex-Kidd) and Ma Kong (ex-Chandler). They remain in commission today.
