Kidd-class destroyer
The "Kidd"-class destroyers were a series of four guided missile destroyers (DDGs) based on the . In contrast to their predecessor's focus on anti-submarine warfare, the "Kidd"s were designed as more advanced multipurpose ships with the addition of considerably enhanced anti-aircraft capabilities. Originally ordered for the former Imperial Iranian Navy, the contracts were canceled when the 1979 Iranian Revolution began, and the ships were completed for the United States Navy. They were decommissioned in 1999 and sold to the Republic of China Navy as the "Kee Lung" class. History. These destroyers were originally ordered by  the last Shah of Iran for service in the Persian Gulf in an air defence role. The original order of six ships was tentatively assigned hull numbers DD 993–998 by the U.S. Navy but it was reduced to four ships after U.S. Congress declined to halt the original production run of 30 "Spruance" ships. Compared to the preceding "Spruance" class, they retained the former's anti-submarine capabilities while adding two Tartar-D missile launchers for the Mark 26/Standard anti-aircraft missile system. In order to operate more effectively in the Middle East, they also had four air conditioning  plants to the Spruances' three, additional dust separators on their gas turbines' air intakes, and increased water distillation capacity. The Shah was overthrown in the Iranian Revolution, prior to Iran accepting delivery of the ships, causing the United States Navy to integrate the vessels into its own fleet in 1981-82 as the "Kidd"-class. On February 3, 1979, Iranian government canceled the second two ships in the class, signing a memorandum of understanding indicating that they were available for acquisition by the U.S. Navy. On February 21. 1979, the Iranian Prime Minister notified the U.S. government that Iran intended to  terminate the contract of the first two ships, officially cancelling delivery on March 8, 1979. Each ship in the class was named after a U.S. Navy Admiral who had died in combat in the Pacific in World War II: Because they were equipped with heavy-duty air conditioning and other features that made them suitable in hot climates, they tended to be used in the Middle East, specifically the Persian Gulf itself. During their service with the U.S. Navy from the 1980s to the late 1990s, the ships were popularly known as the "Ayatollah" class. In 1988–90, the "Kidd"s received  the "New Threat Upgrade", which allowed cooperative engagement with Aegis cruisers, enabling the cruisers to control the "Kidd"s surface-to-air missiles in flight while the destroyers remained electronically silent. However, the arrival of the Aegis-equipped destroyers led to the accelerated retirement of the "Kidd" class. All four ships were decommissioned from the U.S. Navy in the late 1990s, and were initially offered for sale to Australia in 1997 for A$30 million each. In 1999, the offer was rejected, based on extensive problems the Royal Australian Navy had encountered during the acquisition of two surplus s from the  U.S. Navy in 1994. In the early 1990s the Labor government of Paul Keating chose to maintain the Royal Australian Navy's existing "Adelaide"-class frigates instead of replacing them with the more expensive and much more labour-intensive, but more capable "Kidd"-class destroyers. Under the succeeding Liberal government of John Howard, in the mid-1990s they commenced the SEA 1390, also known as the FFG Upgrade Project, to improve the "Adelaide" frigates' capabilities, however this project ran over costs and behind schedule. After the Australian refusal, the four ships were offered to Greece, which also refused. Sale and reactivation. In 2001 , the U.S. authorized the reactivation and sale of all four ships to Taiwan (Republic of China). All four have been transferred to the Republic of China Navy under the Kuang Hua VII program. They were sold for a total price of US$732 million with upgraded hardware, overhaul, activation, and training, included a reduced missile loadout of 148 SM-2 Block IIIA and 32 RGM-84L Block II Harpoon anti-ship missiles. The reactivation was done in Charleston, South Carolina, by VSE/BAV. Section::::"Kee Lung"-class destroyers. The first two ships, ex-"Scott" and ex-"Callaghan", arrived at Su-ao, a military port in eastern  Taiwan, in December 2005, and were named and in a commissioning ceremony on 17 December 2005. Following the tradition of ship class naming, ROCN has referred to these vessels as Kee Lung-class destroyers, with the ships named after military ports in Taiwan. The remaining two units, ex-"Kidd" and ex-"Chandler", were delivered in 2006, and named and , respectively. The opposition-led Legislature Yuan originally allocated only enough money to purchase half of the SM-2 missiles that the destroyers can carry; a further purchase of 100 supplemental SM-2MRs was included in the 2007 annual budget to ensure all four ships had  a full load of SM-2. By end of 2008, "Su Ao" was spotted to have eight HF-3 AShMs installed in place of eight Harpoon AShMs. It has been speculated from 2014 on that a navalized Sky Bow missile system, currently planned for an upcoming shipbuilding programme that involves the procurement of up to 15 general purpose frigates and three or four air defense destroyers, will also be replacing the Standard Missile system on these vessels. No plan for any Mk 26-compatible version of the Sky Bow III missile is ever known to have existed.
