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.

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. 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.

Construction and acquisition

Following the cancellation of the Australian light destroyer project in 1973, the British Type 42 destroyer and the American Oliver Hazard Perry-class frigate were identified as alternatives. [1] Although the Type 42 met the Royal Australian Navy (RAN)'s requirements as a replacement for the cancelled light destroyers and the Daring-class destroyers, fitting the ship with the SM-1 missile would have been difficult. [1] On the other hand, the Oliver Hazard Perry class was still at the design stage; a design that was described by assessment project staff as "a second rate escort that falls short of the DDL [light destroyer] requirements on virtually every respect". [1] [2] Despite this, the Australian government approved the purchase of two US-built Oliver Hazard Perry-class ships in 1974. [1]

The risk of acquiring an unproven design was seen as acceptable because of the success of the United States Navy (USN)'s Charles F. Adams-class destroyer (of which the RAN operated three ships as the Perth class), when compared to the equivalent British ships the RAN would have purchased. [2] Final government approval to order two ships was granted in 1976, with a third ship ordered in 1977. [3] The order was expanded in April 1980 with the order of a fourth unit. [4] These four ships were built by Todd Pacific Shipyards of Seattle, Washington, as part of the USN's shipbuilding program, and were assigned USN hull numbers during construction, which were replaced with RAN pennant numbers upon entering service. [5] The first, HMAS Adelaide (USN hull number FFG-17, RAN pennant number FFG 01) was built to the Flight I design, while Canberra (FFG-18/FFG 02) and Sydney (FFG-35/FFG 03) were the first and last ships of the Flight II design, respectively. [5] The final American-built ship was Darwin (FFG-44/FFG 04); constructed to the Flight III design. [5] In 1980, two more ships (Melbourne and Newcastle) were ordered, but were built in Australia by AMECON of Williamstown, Victoria, and did not receive USN numbers. [4] [5]

Armament

From the withdrawal of the Perth-class destroyers in 2001 until the introduction of the Hobart class in 2017, these ships were 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 anti-ship missile (also fired by the Mark 13 launcher), and a pair of triple torpedo tubes for anti-submarine warfare (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 Typhoon mounts, installed on the aft corners of the hangar roof. [6] Two TopLite EO directors are used with the guns. [6]

The Australian frigates were originally fitted with American Mark 46 ASW 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 Newcastle underway at that point. [7]

Upgrades

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

Lengthening

The first three ships were constructed to the Oliver Hazard Perry class' 'short' hull design (Flight I and II), with an identical length for both the main deck and the keel. [5] Ships from FFG-36 onwards (including Darwin) were built with an increase in overall length—achieved by angling the transom (the section between the fantail and the keel) to increase the area of the flight deck and allow the operation of Seahawk helicopters. [5] Adelaide, Canberra, and Sydney were later upgraded to match the slightly larger ships, and were fitted with the updated sonars and ESM systems of the Flight III design. [5]

FFG Upgrade

In the mid-1990s, Paul Keating's Labor government decided to retain the Adelaide-class frigates instead of replacing them with the more expensive and more labour-intensive, but much more capable Kidd-class destroyers that the USN was selling off. [8] [9] Upgrades to the Oliver Hazard Perry class were problematic, due to "little reserved space for growth (39 tons in the original design), and the inflexible, proprietary electronics of the time", such that the "US Navy gave up on the idea of upgrades to face new communications realities and advanced missile threats". The USN had decommissioned 25 "FFG-7 Short" ships via "bargain basement sales to allies or outright retirement, after an average of only 18 years of service". [8]

Keating's administration was succeeded by the Liberal government of John Howard, which commenced SEA 1390, also known as the FFG Upgrade Project. [8] Originally costing A$1 billion, which eventually increased to A$1.46 billion, the project included improvements to the combat and fire control system, the sonar suite, and the air defence missiles. [8] The upgrade was for four ships and intended to expand their service life to approximately 2020. [8] The project cost was partly offset by the decommissioning of the two oldest units: [10] Canberra paying off in 2005 and Adelaide in 2008. Modification of each ship took place at Garden Island Dockyard, with Australian Defence Industries (ADI, now Thales Australia) selected as project leader for the upgrade phase of the project. [8]

By January 2008, the FFG Upgrade Project was running at least four years behind schedule. [11] The frigates' anti-missile and anti-torpedo detection and defence systems could not be integrated as intended, leaving the ships vulnerable to attack. [11] The first ship refitted, HMAS Sydney, was initially not accepted back into service by the RAN because of the problems, which also prevented any refitted ship from serving in a combat zone. [9] Australian Defence Association executives and serving navy personnel have blamed both political parties for the problems: while the Howard Liberal government was responsible for the project, the preceding Labor government chose to maintain the frigates instead of replacing them with the Kidd-class destroyers in the early 1990s. [8] [9]

By November 2008, Darwin's upgrade had been completed, while the problems experienced with Sydney had been rectified in both ships. [12] It was planned to start deploying these warships to the Gulf in 2009. [12] The RAN and Thales subsequently claimed that the two upgraded ships were the "most capable ships in the history of the RAN", and that once the other two Adelaides were upgraded, the navy would possess the "most lethal frigate fleet on earth". [12] It was reported at the same time that other nations operating guided missile frigates, including the United States, Canada, Greece, and Turkey, were considering similar upgrades. [12]

After the four surviving Adelaide-class ships were refitted, they were capable of firing SM-2MR and RGM-84 Harpoon missiles from the Mark 13 launcher. [8] An 8-cell Mark 41 Vertical Launch System for Evolved Sea Sparrow Missile had also been installed forward of the Mark 13 launcher. The Phalanx CIWS was upgraded to Block 1B, and the torpedoes, missiles, and other ship-mounted weapons were upgraded to the latest versions. [8]

Fates

Canberra and Adelaide were decommissioned to offset the cost of upgrading the remaining four ships, with Canberra decommissioned on 12 November 2005 and Adelaide on 19 January 2008. [10] [13]

Canberra was subsequently sunk as a dive wreck on 4 October 2009, 2 nautical miles (3.7 km; 2.3 mi) off Ocean Grove, Victoria, in 30 metres (98 ft) of water. [14] Adelaide was converted into a dive wreck, but plans to scuttle her off Avoca Beach, New South Wales in April 2010 were postponed following protests by resident action groups and a tribunal hearing, which ordered the removal of wiring and paint from sections of the frigate before she was sunk on 13 April 2011. [15] [16] [17]

Sydney entered port for the final time in February 2015, but remained commissioned as an alongside training ship until 7 November. [18] [19] In May 2017, having not received any offers to convert the hull for use as a dive wreck, Sydney was sold for scrap. [20]

Darwin arrived in Sydney for the last time on 1 November 2017, prior to her decommissioning ceremony on 9 December. [21] [22]

The upgraded Adelaide-class frigates were replaced by three new Hobart-class air warfare destroyers, equipped with the Aegis combat system, starting around 2016.

In April 2017, the Polish government officially expressed interest in purchasing two of the remaining three frigates when they are retired from service. [23] [24] Negotiations between the Australian and Polish Governments for the sale were unsuccessful. In January 2019 the Greek Government sent an expression of interest to the Department of Defence for Melbourne and Newcastle. [25] In May 2019 it was reported that Chile had also showed interest in the two frigates. [26] On 27 December 2019, it was announced that Melbourne and Newcastle had been sold to Chile.

On 15 April 2020 the ships were handed over to the Chilean Navy and renamed Capitan Prat (FFG-11) (ex HMAS Newcastle), and Almirante Latorre (FFG-14) (ex HMAS Melbourne) [27]

The Oliver Hazard Perry class is a class of guided-missile frigates named after U.S. Commodore Oliver Hazard Perry, the hero of the naval 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.

HMAS <i>Darwin</i> (FFG 04) Adelaide-class frigate

HMAS Darwin, named for the capital city of the Northern Territory, was an Adelaide-class guided-missile frigate, formerly in service with the Royal Australian Navy (RAN). One of four ships ordered from the United States, Darwin entered service in 1984. During her career, she has operated in the Persian Gulf, as part of the INTERFET peacekeeping taskforce, and off the Solomon Islands. The frigate underwent a major upgrade during 2007 and 2008. She was decommissioned on 9 December 2017 and was supposed to be scuttled as a dive wreck in Tasmania, but the deal was pulled by the Tasmanian Government and her fate remains uncertain.

HMAS <i>Newcastle</i> Adelaide-class frigate

HMAS Newcastle, named for the city of Newcastle, New South Wales, the largest provincial city in Australia, was an Adelaide-class guided-missile frigate. The last ship of the class to be constructed, Newcastle entered service with the Royal Australian Navy in 1993. During her career, the frigate has operated as part of the INTERFET peacekeeping taskforce, served in the Persian Gulf, and responded to the 2006 Fijian coup d'état. The frigate was decommissioned on 30 June 2019 and transferred to the Chilean Navy on 15 April 2020 and renamed as Capitán Prat.

HMAS <i>Adelaide</i> (FFG 01) Frigate of the Royal Australian Navy, lead ship of the class

HMAS Adelaide was the lead ship of the Adelaide class of guided missile frigates built for the Royal Australian Navy (RAN), based on the United States Navy's Oliver Hazard Perry-class frigates. She was built in the United States and commissioned into the RAN in 1980.

<i>Anzac</i>-class frigate Australian military ship class

The Anzac class is a ship class of ten frigates; eight operated by the Royal Australian Navy (RAN) and two operated by the Royal New Zealand Navy (RNZN). During the 1980s, the RAN began plans to replace the River-class destroyer escorts with a mid-capability patrol frigate and settled on the idea of modifying a proven German design for Australian conditions. Around the same time, the RNZN was seeking to replace their Leander-class frigates while maintaining blue-water capabilities. A souring of relations between New Zealand and the United States of America in relation to New Zealand's nuclear-free zone and the ANZUS security treaty prompted New Zealand to seek improved ties with other nations, particularly Australia. As both nations were seeking warships of similar capabilities, the decision was made in 1987 to collaborate on their acquisition. The project name is taken from the Australian and New Zealand Army Corps of the First World War.

HMAS <i>Parramatta</i> (FFH 154) Anzac-class frigate of the Royal Australian Navy

HMAS Parramatta is an Anzac-class frigate of the Royal Australian Navy (RAN). One of ten warships built for the RAN and Royal New Zealand Navy (RNZN) based on the MEKO 200 design, Parramatta was laid down in 1999, launched in 2003, and commissioned into the RAN in 2003. During her career, the frigate has been deployed to the Middle East on several occasions. In early 2015, Parramatta was docked to undergo the Anti-Ship Missile Defence (ASMD) upgrade. She completed these upgrades in April 2016.

HMAS <i>Sydney</i> (FFG 03)

HMAS Sydney was an Adelaide-class guided-missile frigate of the Royal Australian Navy (RAN). The frigate was one of six modified Oliver Hazard Perry-class frigates ordered from 1977 onwards, and the third of four to be constructed in the United States of America. Laid down and launched in 1980, Sydney was named for the capital city of New South Wales, and commissioned into the RAN in 1983.

HMAS <i>Toowoomba</i> (FFH 156) Anzac-class frigate of Royal Australian Navy

HMAS Toowoomba is the seventh Anzac-class frigate of the Royal Australian Navy (RAN). She was laid down in 2002 by Tenix Defence and commissioned in 2005.

HMAS Warramunga is an Anzac-class frigate of the Royal Australian Navy (RAN). One of ten frigates built for the Australian and New Zealand navies, Warramunga was laid down by Tenix Defence in 1997 and commissioned in 2001. During her career, the frigate has operated in the Persian Gulf as part of Operation Catalyst, and undertaken anti-piracy operations off Somalia. Warramunga underwent the Anti-Ship Missile Defence (ASMD) upgrade during 2014. She is active as of October 2022.

HMAS <i>Ballarat</i> (FFH 155) Anzac-class frigate of Royal Australian Navy

HMAS Ballarat is an Anzac-class frigate of the Royal Australian Navy (RAN). The frigate was laid down in 2000 and commissioned into the RAN in mid-2004. Since entering service, Ballarat has been involved in border protection as part of Operation Relex II, was deployed to the Gulf for Operation Catalyst, and was one of the two ships involved in the Operation Northern Trident 2009 round-the-world voyage. Ballarat has undergone the Anti-Ship Missile Defence (ASMD) upgrade, completing in 2015.

HMAS <i>Melbourne</i> (FFG 05) Adelaide-class guided missile frigate of the Royal Australian Navy

HMAS Melbourne was an Adelaide-class guided-missile frigate of the Royal Australian Navy, which entered service in 1992. Melbourne has been deployed to the Persian Gulf on several occasions, and served as part of the INTERFET peacekeeping taskforce in 2000. On 26 October 2019, Melbourne was decommissioned from the RAN, subsequently being transferred to Chile. The ship was commissioned into the Chilean Navy as Almirante Latorre on 15 April 2020.

HMAS <i>Canberra</i> (FFG 02) Guided missile frigate

HMAS Canberra was an Adelaide class guided missile frigate of the Royal Australian Navy (RAN). Based on the Oliver Hazard Perry class design, Canberra was one of four Adelaide class ships constructed in the United States of America, and one of six to serve in the RAN.

HMAS <i>Kanimbla</i> (L 51) Amphibious Ship operated by the Australian Navy

HMAS Kanimbla was a Kanimbla-class landing platform amphibious ship operated by the Royal Australian Navy (RAN). Originally built for the United States Navy (USN) as the Newport-class tank landing shipUSS Saginaw (LST-1188), the ship was decommissioned in 1994 and sold to the RAN.

<i>Hobart</i>-class destroyer Class of destroyer of Royal Australian Navy

The Hobart class is a ship class of three air warfare destroyers (AWDs) built for the Royal Australian Navy (RAN). Planning for ships to replace the Adelaide-class frigates and restore the capability last exhibited by the Perth-class destroyers began by 2000, initially under acquisition project SEA 1400, which was re-designated SEA 4000. Although the designation "Air Warfare Destroyer" is used to describe ships dedicated to the defence of a naval force from aircraft and missile attack, the planned Australian destroyers are expected to also operate in anti-surface, anti-submarine, and naval gunfire support roles.

HMAS <i>Manoora</i> (L 52)

HMAS Manoora was a Kanimbla-class landing platform amphibious ship operated by the Royal Australian Navy (RAN). Originally built for the United States Navy (USN) as the Newport-class tank landing shipUSS Fairfax County (LST-1193), the ship was decommissioned in 1994 and sold to the RAN.

The Royal Australian Navy, although a significant force in the Asia-Pacific region, is nonetheless classed as a medium-sized navy. Its fleet is based around two main types of surface combatant, with limited global deployment and air power capability. However, in 2009, a white paper, Defending Australia in the Asia Pacific Century: Force 2030, was produced by the Australian government which set out a programme of defence spending that will see significant improvements to the RAN's fleet and capabilities.

<i>Kanimbla</i>-class landing platform amphibious

The Kanimbla class was a class of amphibious transport ships operated by the Royal Australian Navy (RAN). Two ships were purchased by Australia in 1994 and modified. Problems during the handover process and the need to repair previously unidentified defects meant the ships did not enter operational service until the end of the decade.

<i>Perth</i>-class destroyer

The Perth-class destroyers were three modified Charles F. Adams-class guided missile destroyers operated by the Royal Australian Navy (RAN). Ordered from Defoe Shipbuilding Company during 1962 and 1963, HMA Ships Perth, Hobart, and Brisbane were the first guided missiled-armed warships, and the first naval ships of United States design, to enter service with the RAN. All three ships operated during the Vietnam War, while Brisbane also participated in the Gulf War. The class was decommissioned between 1999 and 2001, with all three vessels later sunk as dive wrecks.
