The Adelaide class is the name given to the Oliver Hazard Perry class frigates in service in the Royal Australian Navy. The first four units were built as the eleventh, twelfth, twenty-ninth and thirty-eighth in the US Navy production run, with the final two units built in Australia. The ships are classed as guided missile frigates, with a weapons fit optimised for general warfare.
Since the withdrawal of the Perth class destroyers, these ships are the RAN's primary air defence vessels, armed with the SM-1 missile. They also have significant surface capability thanks to a 76 mm Mk 75 gun and the Harpoon ASM, and a pair of triple torpedo tubes for ASW. In addition, a pair of S-70B Seahawk  helicopters are carried.
