The Adelaide class of six guided missile frigates was constructed in Australia and the United States for service in the Royal Australian Navy.[1] Two were later sold to the Chilean Navy. The Adelaide 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, and the final two were 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 offset the cost of a A$1 billion weapons and equipment upgrade to the remaining four ships.[2] As the Hobart-class air-warfare destroyers entered service beginning in 2016, the remaining Adelaide-class ships were progressively decommissioned beginning with Sydney in 2015. Darwin followed in 2017, and Newcastle and Melbourne went last in 2019. The final two were sold to Chile in 2020.
