The Fremantle-class patrol boats were coastal

patrol vessels operated by the Royal Australian Navy (RAN) from 1979 to 2007. Designed by British shipbuilder Brooke Marine and constructed in Australia by NQEA, the Fremantle class were larger, more powerful, and more capable than the preceding Attack class
, and the two primary patrol boat bases required infrastructure upgrades to support them. Although up to 30 vessels were planned, fifteen were ordered and constructed, with an unexercised option for five more.

Their retirement was announced in 2001 and a decommissioning schedule published in 2004. From May 2005 they were replaced by the Armidale-class patrol boats with the last two Fremantles decommissioning in May 2007. Most of the class were scrapped, with two marked for preservation as museum ships. The Fremantle class has also appeared in two drama television series based on the Royal Australian Navy.

Planning and development

The concept for the Fremantle class began somewhere between 1967 and 1969, as the

military of Papua New Guinea),[1] and settling at fifteen.[2]

Plans of acquisition were announced in April 1975, with eleven shipbuilders submitting tenders, of which two were shortlisted in 1976;

Lürssen Werft of West Germany.[2] Brooke Marine won the contract to design and produce the lead ship, with NQEA contracted to build the other fourteen vessels.[2] An option for an additional five vessels existed, but they were placed on indefinite hold in 1982.[2][3] There was a separate acquisition plan for six missile-armed variants, but this was suspended due to the lack of available funding, and the belief that such ships could be constructed on short notice if required.[3]

Design and construction

The design of the Fremantle class called for ships with improved seakeeping, and newer equipment and weapons than those fitted to the Attack class.

.50-calibre Browning machineguns and an 81 mm mortar,[4][8] although the mortar was removed from all ships sometime in the late 1990s.[citation needed] The main weapon was originally to be two 30-mm guns on a twin-mount, but the reconditioned Bofors were selected to keep costs down; provision was made to install an updated weapon later in the class' service life, but this did not eventuate.[3][7]

Early on in the construction program, it was realised that the two main patrol boat bases,

Cairns, Queensland and HMAS Coonawarra in Darwin, Northern Territory, were not capable of supporting ships of this size on a permanent basis.[5] This resulted in a $10 million infrastructure upgrade for the two bases, which was completed in 1981 and 1982, respectively.[7] This included modern maintenance, logistic, and administrative facilities at both bases, and the installation of a synchro-lift at Coonawarra.[5]

Cessnock underway in the mid-1980s

Construction of Fremantle began in October 1977.

commercial trawler following its collision with an oil tender.[6] Construction of the first Australian-built vessel, HMAS Warrnambool, began in September 1978, with Warrnambool launched on 25 October 1980 and commissioned on 14 March 1981.[9] The final ship of the class, HMAS Bunbury, was commissioned on 15 December 1984.[9] The Australian-built vessels were built through an assembly-line method.[7] Hulls were built upside-down from the keel to the second-uppermost deck, then rolled over and built to the top of the hull.[7] After this, the superstructure, which had been fabricated at the same time, was welded onto the hull.[7] Construction of the class (including the two naval base upgrades) cost $150 million.[7] All fifteen vessels were named after Bathurst-class corvettes.[3]

Operational history

The first ship of the class,

HMAS Cerberus.[11] Also by 1984, all of the Attack class had left active service, with many transferring to the RAN Reserve or the Indonesian Navy.[11]

On 31 May 1985, Wollongong grounded on rocks at Gabo Island, causing extensive damage to the vessel.[7] It was repaired by the builder, and returned to service in late 1986.[7]

From May 2005 onwards, the Fremantles were replaced in service by the fourteen Armidale-class patrol boats. During late 2006, the decommissioned Wollongong remained laid up alongside Waterhen in Waverton, Sydney for use as the alongside set for the drama series Sea Patrol. The last two ships, Townsville and Ipswich, decommissioned in a joint ceremony on 11 May 2007.[12]

Fate

Gladstone in 2010, awaiting preservation in its namesake city

During 2006 and 2007, most of the Fremantles were broken up for scrap in Darwin, at a cost of between $400,000 and $450,000 each to the Australian government.[13] A total of 11 of the class were dismantled at Darwin, although the MTU engines were salvaged and sold on market, and some high value item were also saved.[14] The exceptions were Wollongong (which was instead scrapped in Port Macquarie), Townsville (gifted to the Townsville Maritime Historical Society for preservation as a museum ship), and Gladstone (gifted to the Gladstone Maritime Museum for preservation).[13][15]

Fremantle class in fiction

HMAS Hammersley alongside at HMAS Waterhen

The fictional HMAS Defiance, portrayed by HMA Ships Launceston, Townsville, Warrnambool, Whyalla, and Wollongong featured in the second season of the Australian Broadcasting Corporation television series Patrol Boat.[16]

The fictional HMAS Hammersley is the setting of the first season of Channel Nine's 2007 drama series Sea Patrol. This vessel was portrayed by HMA Ships Wollongong and Ipswich.[17] A second patrol boat, HMAS Kingston, also appears in the series. From the second season onwards, an Armidale-class boat is used.
