The Adelaide class of six guided missile frigates was constructed in Australia and the United States for service in the Royal Australian Navy. 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.

The Oliver Hazard Perry class is a class of guided-missile frigates named after U.S. Commodore Oliver Hazard Perry, a commander noted for his role in the Battle of Lake Erie. Also known as the Perry or FFG-7 class, the warships were designed in the United States in the mid-1970s as general-purpose escort vessels inexpensive enough to be bought in large numbers to replace World War II-era destroyers and complement 1960s-era Knox-class frigates.
