Adelaide Class Guided Missile Frigates
The RAN introduced six guided missile frigates of the Adelaide Class (HMA ships Adelaide, Canberra, Darwin, Melbourne, Newcastle and Sydney), based on the US Navy Oliver Hazard Perry design. Each FFG ship was a long-range escort ship with roles including air defence, anti-submarine warfare, surveillance, interdiction and reconnaissance.
These ships were the first RAN ships to be powered by gas turbine for the main propulsion and could be underway from cold in less than 30 minutes. The FFG’s principal weapons were the Standard medium-range anti-aircraft missile and the Harpoon anti-ship missile. A 76mm gun to counter air and surface threats is fitted forward of the funnel and one 20mm Phalanx close-in-weapon-system for anti-missile defence is located above the helicopter hangers.
For long-range anti-submarine tasks, the FFG is equipped with a flight deck and hangers for two S-70B-2 Seahawk helicopters. For close-in anti-submarine defence, the ships are fitted with two Mk32 triple torpedo tubes.
