Kidd-class destroyer
In contrast to their predecessor's focus on anti-submarine warfare, the Kidds were designed as more advanced multipurpose ships with the addition of considerably enhanced anti-aircraft capabilities.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.[5] 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.[8] The Royal Australian Navy was a strong supporter of buying the Kidd-class destroyers to replace the Perth class as their air warfare ships.[8] 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.
