Frigate Adelaide-class warships

Search Contents

The frigate class Adelaide is the Australian variant of the American Oliver Hazard Perry-class guided missile frigate. A total of six Adelaide-class frigates were built for the RAN. Four were built by Todd Pacific Shipyards inSeattle, Washington, while the final two were built by AMECON in Williamstown, Victoria. They first entered service in 1980, and with the retirement of the Perth-class destroyers, have become the RAN’s primary air defence asset. Four of the frigates received upgrades to their weapons and systems during the 2000s, of which three remain in service. The other three ships have been paid off: the first two in the late 2000s to free up funds for the modernisation, and the third in 2015.

Defense systems and Armament

Several changes occurred in the RAN since the withdrawal of the Perth-class destroyers. these ships are the RAN’s primary air defence vessels, armed with a Mark 13 missile launcher for SM-2 missiles. They also have significant anti-surface capability, being armed with a 76-millimetre (3.0 in) Mk 75 gun and the Harpoon ASM (also fired by the Mark 13 launcher), and a pair of triple torpedo tubes for ASW. In addition, two S-70B Seahawk helicopters are carried.

From 2005 onwards, all RAN frigates deploying to the Persian Gulf are fitted with two M2HB .50 calibre machine guns in Mini Typhoonmounts, installed on the aft corners of the hangar roof] Two TopLite EO directors are used with the guns.

The Australian frigates were originally fitted with American Mark 46 anti-submarine torpedoes, but by 2008, they had been replaced with the European MU90 Impact torpedo in three of the four frigates as part of the FFG Upgrade, with the conversion of Newcastleunderway at that point.

There have been two major upgrades distinguishing the Adelaide class from the American Oliver Hazard Perry-class.

Frigate surface Force (11): The principal striking force of the RAN comes from the eleven frigates of the surface force: eight of them belong to the Anzac class and the rest (three) are units from the Adelaide class.

Submarine Striking Force (6): The RAN operates six Collins-class submarines. Due to technical and manpower problems these submarines might be replaced in the future by Japanese Soryu-class submarines.

Amphibious Force (3): There are a huge variety of amphibious warfare units, which include two Canberra-class landing helicopter dock ships and the landing ship HMAS Choules.

Patrol Boat Force (13): There are thirteen Armidale-class patrol boats that perform coastal and economic exclusion zone patrols.

Mine Hunting and Warfare Force (4 + 2 in reserve):
There are four Huon-class vessels that are used for minehunting and clearance (another two are commissioned but in reserve since October 2011).

Replenishment Force (2 + 6 survey duties):
The task for replenishment at sea is provided by two ships, Sirius and Success. In addition, there are two Leeuwin-class and four Paluma-class vessels perform survey and charting duties.

Training Units (1 + 1 support vessel + 2 patrol boats):
The RAN operates the sail training ship Young Endeavour, the support vessel ADV Ocean Shield, and two Cape-class patrol boats. The latter ones are acquired thanks to the Australian Border Force.
