Фрегаты типа «Аделаида»

The Adelaide class was a ship class of six guided missile frigates constructed in Australia and the United States of America for service in the Royal Australian Navy. The class was based on the United States Navy's Oliver Hazard Perry-class frigates, but modified for Australian requirements. The first four vessels were built in the United States, with the final two being constructed in Australia.

The first ship entered service in November 1980. Canberra and Adelaide were paid off in 2005 and 2008 respectively, and later sunk as dive wrecks: their decommissioning was to offset the cost of a A$1 billion weapons and equipment upgrade to the remaining four ships. Sydney was decommissioned in late 2015, after spending most of the year as a moored training ship. Darwin was decommissioned in late 2017, Newcastle in June 2019 and Melbourne the last in October 2019. The Hobart-class air-warfare destroyers progressively replaced the last four frigates from 2016 onwards.
